Objective: To examine sleep patterns in adults with maturity-onset diabetes of the young (MODY)., Research Design and Methods: Adults with glucokinase (GCK)-MODY and transcription factor (TF)-related MODY (HNF1A, HNF1B, HNF4A) were recruited (n = 24; age 46.0 years, 79% women, BMI 24.7 kg/m2) from The University of Chicago's Monogenic Diabetes Registry. Sleep patterns were assessed by 2-week wrist actigraphy (total 315 nights), one night of a home sleep apnea test, and validated surveys., Results: Overall, compared with established criteria, 29% of participants had sleep latency ≥15 min, 38% had sleep efficiency ≤85%, 46% had wake after sleep onset >40 min, all indicating poor objective sleep quality. Among all participants, 54% had a sleep duration below the recommended minimum of 7 h, 88% reported poor sleep quality, 58% had obstructive sleep apnea, and 71% reported insomnia. Compared with GCK-MODY, participants with TF-related MODY had poorer objective sleep quality and increased night-to-night variability in sleep patterns., Conclusions: Sleep disturbances appear to be common in adults with MODY despite absent traditional risk factors for sleep disorders. Future research investigating the sleep-diabetes relationship is warranted in this population., (© 2023 by the American Diabetes Association.)

The role of melatonin has been extensively investigated in pathophysiological conditions, including autism spectrum disorder (ASD). Reduced melatonin secretion has been reported in ASD and led to many clinical trials using immediate-release and prolonged-release oral formulations of melatonin. However, melatonin's effects in ASD and the choice of formulation type require further study. Therapeutic benefits of melatonin on sleep disorders in ASD were observed, notably on sleep latency and sleep quality. Importantly, melatonin may also have a role in improving autistic behavioral impairments. The objective of this article is to review factors influencing treatment response and possible side effects following melatonin administration. It appears that the effects of exposure to exogenous melatonin are dependent on age, sex, route and time of administration, formulation type, dose, and association with several substances (such as tobacco or contraceptive pills). In addition, no major melatonin-related adverse effect was described in typical development and ASD. In conclusion, melatonin represents currently a well-validated and tolerated treatment for sleep disorders in children and adolescents with ASD. A more thorough consideration of factors influencing melatonin pharmacokinetics could illuminate the best use of melatonin in this population. Future studies are required in ASD to explore further dose-effect relationships of melatonin on sleep problems and autistic behavioral impairments.

Objective: To describe the sleep disorders in anti-NMDA receptor encephalitis (anti-NMDARe)., Methods: Patients recovering from anti-NMDARe were invited to participate in a prospective observational single-center study including comprehensive clinical, video-polysomnography (V-PSG) sleep assessment, and neuropsychological evaluation. Age- and sex-matched healthy participants served as controls., Results: Eighteen patients (89% female, median age 26 years, interquartile range [IQR] 21-29 years) and 21 controls (81% female, median age 23 years, IQR 18-26 years) were included. In the acute stage, 16 (89%) patients reported insomnia and 2 hypersomnia; nightmares occurred in 7. After the acute stage, 14 (78%) had hypersomnia. At study admission (median 183 days after disease onset, IQR 110-242 days), 8 patients still had hypersomnia, 1 had insomnia, and 9 had normal sleep duration. Patients had more daytime sleepiness than controls (higher Barcelona Sleepiness Index, p = 0.02, and Epworth Sleepiness Score, p = 0.04). On V-PSG, sleep efficiency was similar in both groups, but patients more frequently had multiple and longer confusional arousals in non-REM (NREM) sleep (videos provided). In addition, 13 (72%) patients had cognitive deficits; 12 (67%) had psychological, social, or occupational disability; and 33% had depression or mania. Compared with controls, patients had a higher body mass index (median 23.5 [IQR 22.3-30.2] vs 20.5 [19.1-21.1] kg/m 2 ; p = 0.007). Between disease onset and last follow-up, 14 (78%) patients developed hyperphagia, and 6 (33%) developed hypersexuality (2 requiring hospitalization), all associated with sleep dysfunction., Conclusions: Sleep disturbances are frequent in anti-NMDARe. They show a temporal pattern (predominantly insomnia at onset; hypersomnia during recovery), are associated with behavioral and cognitive changes, and can occur with confusional arousals during NREM sleep., (© 2020 American Academy of Neurology.)

Purpose: We aimed to explore the risk factors of preoperative sleep quality in patients with lumbar spinal stenosis (LSS) and the association of sleep-related beliefs with sleep quality in these patients., Methods: Sleep quality and related risk factors of sleep quality disturbances in patients with LSS preoperatively were assessed by questionnaires. Pittsburgh Sleep Quality Index (PSQI) for sleep quality, Oswestry Disability Index (ODI) for clinical outcomes, Visual Analog Scale for Pain (VAS Pain), Self-Rating Anxiety Scale (SAS) for anxiety level, and Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16) for sleep-related beliefs were assessed. Bivariate logistic regression analysis was used to assess the risk factors of sleep quality disturbances., Results: A total of 227 patients were enrolled, mean age 64 years (SD 13.1), 119 women (52%). The incidence of sleep quality disturbances in patients was 37% (83/227). Increased DBAS-16 scores (OR = 0.781; 95% CI, 0.725-0.841; p < 0.001) significantly decreased the probability of developing sleep quality disturbances, while increased anxiety levels (OR = 1.241; 95% CI, 1.152-1.337; p < 0.001) significantly increased the probability of developing sleep quality disturbances in patients. Factors including educational level, increased age, sex, preoperative length of stay, VAS Pain scores, and ODI scores showed no significant association and were therefore excluded from the model., Conclusions: High levels of anxiety and mistaken sleep-related beliefs were risk factors of sleep quality disturbances in patients with LSS before surgery. The more mistaken sleep-related beliefs were, the greater the probability of sleep disturbances.

Despite decades of research on Parkinson's disease (PD), the etiology of this disease remains unclear. The present manuscript introduces a new hypothesis proposing a hyper-serotonergic state as the main mechanism leading to axonal impairment both in dopaminergic and serotonergic neurons in PD. The strong serotonergic connection between the raphe nuclei and the dorsal raphe nuclei with the basal ganglia, all important brain structures associated with the pathophysiology of PD, emphasize a potential role for this neurotransmitter in PD. Importantly, a hyper-serotonergic state can lead to axonal growth impairment, an effect that seems to be selective to axons that can respond to this neurotransmitter. Serotonin seems to be a promising candidate to explain several of the poorly understood early symptoms of PD, including sleep impairment, anxiety, altered gastrointestinal motility and hallucinations. The hypothesis proposed here emphasizes that a hyper-serotonergic state would initially cause disruption of axonal transportation, an acute state in which axonal changes are reversible and the neurodegenerative process can be halted. As the hyper-serotonergic state persists, the accumulation of neurotoxic products and a sustained impairment in axonal transportation would lead to axonal death and culminate in an irreversible neurodegenerative process. The potential implications of this hypothesis are discussed, as well as how future research can be employed to further elucidate the role of serotonin on PD progression., (Copyright © 2019 Elsevier Ltd.

Sleep complaints are an early clinical symptom of neurodegenerative disorders. Patients with Parkinson's disease (PD) experience sleep disruption (SD). The objective of this study was to determine if preexisting, chronic SD leads to a greater loss of tyrosine hydroxylase (TH) within the striatum and the substantia nigra following chronic/progressive exposure with the neurotoxin, 1-methyl-2-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Male mice underwent chronic SD for 4 weeks, then injected with vehicle (VEH) or increasing doses of MPTP for 4 weeks. There was a significant decrease in the plasma corticosterone levels in the MPTP group, an increase in the SD group, and a return to the VEH levels in the SD+MPTP group. Protein expression levels for TH in the striatum (terminals) and substantia nigra pars compacta (dopamine [DA] cell counts) revealed up to a 78% and 38% decrease, respectively, in the MPTP and SD+MPTP groups compared to their relevant VEH and SD groups. DA transporter protein expression increased in the striatum in the MPTP versus VEH group and in the SN/midbrain between the SD+MPTP and the VEH group. There was a main effect of MPTP on various gait measures (e.g., braking) relative to the SD or VEH groups. In the SD+MPTP group, there were no differences compared to the VEH group. Thus, SD, prior to administration of MPTP, has effects on serum corticosterone and gait but more importantly does not potentiate greater loss of TH within the nigrostriatal pathway compared to the MPTP group, suggesting that in PD patients with SD, there is no exacerbation of the DA cell loss., (© 2019 Wiley Periodicals, Inc.)

Rationale: Hypoglycemia, which is characterized mainly by palpitations, dizziness, and sweating, is common and easy to identify. However, some other symptoms, such as mental disorder or abnormal behavior, are atypical, which may lead to a misdiagnosis of epilepsy, sleepwalking, infarction, or mental disorder, among others., Patient Concerns: We report a case of a patient with type 2 diabetes who presented with abnormal nocturnal behavior due to hypoglycemia., Diagnosis: Hypoglycemia was diagnosed based on a blood glucose level of 2.1 mmol/L when the patient turned up disoriented unresponsive, unable to understand what was said to him, and producing nonsensical speech. After the patient ate a piece of chocolate, his consciousness returned to normal and all mental symptoms disappeared. Polysomnography (PSG) was synchronously performed. The results of the PSG did not show any signs of abnormality during nonrapid eye movement (NREM) or rapid eye movement (REM) sleep., Interventions: We regulated his dose of insulin., Outcomes: No additional episodes occurred during the 3-month follow-up. Therefore, the abnormal nocturnal behavior of this patient was determined to be due to hypoglycemia, while the cause of the hypoglycemia was insulin overuse., Lessons: For physicians, if the cause of abnormal behavior cannot be detected, hypoglycemia should be suspected. Long-term persistent hypoglycemia may cause brain dysfunction and even result in permanent brain damage.

Introduction: Poor sleep quality and excessive daytime sleepiness are common in patients with cystic fibrosis (CF), and both are negatively correlated with health-related quality of life (HRQoL). The objective of our study was to evaluate subjective and objective sleep quality in adult CF patients and its effect on HRQoL., Materials and Methods: This was a descriptive, prospective, cross-sectional study of CF patients > 18 years of age. Patients underwent nocturnal polysomnography (PSG) and were administered the Pittsburgh Sleep Quality Index questionnaire (PSQI) and the Cystic Fibrosis Quality of Life Questionnaire (CFQR 14 + Spain)., Results: The study included 23 patients, 14 women (61%). The mean age of the participants was 32 + 18 years. The mean PSQI score was 5.57 + 3.55; 13 (56.5%) of the patients were poor sleepers, and 13% reported poor sleep quality; seven (30%) had sleep latency > 30 min, 10 (43.5%) had sleep efficiency < 85%. Nineteen underwent polysomnography. According to PSG measurements, sleep efficiency was less than 90% in 61% of the patients. Pathological values were found for the following parameters: intra-sleep wakefulness in 12 patients (63%); microarousal index in 12 patients (63%); and apnea-hypopnea index (AHI) in 2 patients. The desaturation time with SpO 2  < 90% (T90) was > 30% in 3 patients. We observed a significant correlation between PSQI and all dimensions of CFQR 14., Conclusions: Subjective and objective sleep efficiency decreases in adult CF patients. Sleep quality has an impact on HRQoL. The PSQI questionnaire was able to discriminate sleep quality.

Overview: Whilst the majority of evidence supports the adjunctive use of eicosapentaenoic acid (EPA) in improving mood, to date no study exists using low-dose docosahexaenoic acid (DHA) alone as an adjunctive treatment in patients with mild to moderate major depressive disorder (MDD)., Methods: A naturalistic 8-week open-label pilot trial of low-dose DHA, (260 mg or 520 mg/day) in 28 patients with MDD who were non-responsive to medication or psychotherapy, with a Hamilton Depression Rating Scale (HAM-D) score of greater than 17, was conducted. Primary outcomes of depression, clinical severity, and daytime sleepiness were measured., Results: After 8 weeks, 54% of patients had a ≥50% reduction on the HAM-D, and 45% were in remission (HAM-D ≤ 7). The eta-squared statistic (0.59) indicated a large effect size for the reduction of depression (equivalent to Cohen's d of 2.4). However confidence in this effect size is tempered due to the lack of a placebo. The mean score for the Clinical Global Impression Severity Scale was significantly improved by 1.28 points (P < 0.05). Despite a significant reduction in the HAM-D score for middle insomnia (P = 0.02), the reduction in excessive daytime somnolence on the total Epworth Sleepiness Scale (ESS) did not reach significance. No significant adverse reactions to DHA were found., Conclusion: Within the major limits of this open-label pilot study, the results suggest that DHA may provide additional adjunctive benefits in patients with mild- to -moderate depression.

Objectives: This observational, cross-sectional study included 140 women with climacteric symptoms. The aim of the study was to evaluate the correlation between the presence and severity of depressive symptoms and allopregnanolone levels in women during late menopausal transition and early postmenopause., Methods: The study group was divided into two groups: 45 women in late menopausal transition and 95 early postmenopausal women. We evaluated Kupperman index, Hamilton scale and serum follicle-stimulating hormone, luteinizing hormone, 17β-estradiol, prolactin, total testosterone, dehydroepiandrosterone sulfate and allopregnanolone levels., Results: We found that serum allopregnanolone concentration was lower in early postmenopausal women compared to women in late menopausal transition; that there was a correlation between serum allopregnanolone levels in early postmenopausal women and time since last menstruation, intensity of climacteric symptoms, and intensity of depression symptoms and that there was a correlation between serum allopregnanolone levels and several depression symptoms presence (shallow sleep and symptoms of the digestive tract in women during late menopause transition; feelings of guilt, sleep disorders and general somatic symptoms in early postmenopausal women)., Conclusion: We concluded that reproductive aging is characterized by a reduction of allopregnanolone circulating levels that correlate to Hamilton depression index in early postmenopause and presence of specific depressive symptoms during late menopausal transition and early postmenopause.

Introduction: Attention deficit hyperactivity disorder (ADHD) affects approximately 5% of all children and adolescents, and these patients frequently suffer from sleep problems. The association between sleep disorders and ADHD, however, is multifaceted and complex., Aims: To explore the relationship between sleep disorders and ADHD., Development: Sleep problems in children with ADHD include altered sleep and specific disorders per se or that may be due to comorbid psychiatric disorders or to the stimulants they receive as treatment for their ADHD. Today, an evaluation of the sleep conditions in children with ADHD is recommended before starting pharmacological treatment. The first step in managing their sleep problems is good sleep hygiene and cognitive-behavioural psychotherapy. Another option is to consider modifying the dosage and formulation of the stimulants. Atomoxetine and melatonin are therapeutic alternatives for children with ADHD and more severe sleep problems. Specific treatments exist for respiratory and movement disorders during sleep., Conclusions: It is important to evaluate sleep in children who present symptoms suggestive of ADHD, since problems during sleep can play a causal role or exacerbate the clinical features of ADHD. Correct evaluation and treatment of sleep disorders increase the family's and the child's quality of life and can lessen the severity of the symptoms of ADHD.

In Parkinson's disease, motor signs have long been the main targets of the management of the disease. In recent years, non-motor disorders have elicited increasing interest. These disorders are under diagnosed and managed more difficultly than motor signs and are sometimes perceived as more disturbing by the patients. These signs are polymorphous, sometimes occurring before the motor symptoms but increase with the disease duration and complicating always the late stages. They may fluctuate as the motor signs, while being under the control of dopaminergic pathways, or be linked to the degeneration of other neuronal circuits. These clinical manifestations, whether or not fluctuating are classified into three major categories: psycho-cognitive including sleep disorders, autonomic and sensory., (Copyright © 2016 Elsevier Masson SAS.

Objective: To determine if the non-motor sections of the Movement Disorder Society's (MDS) version of the Unified Parkinson's Disease Rating Scale (UPDRS) could supplement the original UPDRS as a patient completed assessment of changes in non-motor symptoms in Parkinson's disease (PD) patients after bilateral subthalamic nucleus (STN) deep brain stimulation (DBS)., Methods: Thirty PD patients who underwent bilateral STN DBS were assessed using the total UPDRS and the non-motor sections of the MDS-UPDRS prior to surgery and one year following surgery. This study focuses on non-motor symptoms as assessed by Part I of the UPDRS and Part 1A and 1B of the MDS-UPDRS., Results: One year following surgery, no individual non-motor symptoms or the total mentation score of the UPDRS were significantly changed. In comparison, the MDS-UPDRS showed significant improvements in sleep and urinary problems and a trend towards improvement in anxiety, constipation, daytime sleepiness, fatigue and pain., Conclusions: This study provides evidence that the MDS-UPDRS non-motor sections, when completed by the patients, can supplement the original version of the UPDRS as an effective method of measuring changes in non-motor symptoms after DBS. It also reinforces the benefits of bilateral STN DBS on non-motor symptoms of PD.

This study aimed at assessing effect of the four dimensions of work-family conflicts (strain and time-based work interference into family and family interference into work) on sleep disturbance in Malaysian working women. This cross-sectional study was conducted among 325 Malaysian married working women. Multiple-stage simple random sampling method was used to recruit women from public service departments of Malaysia. Self-administrated questionnaires were used to measure the study variables and data were analyzed using SPSS version 21. We found that high level of the four dimensions of work-family conflicts significantly increase sleep disturbance. Our analyses also revealed an age-dependent effect of the work-family conflict on sleep disturbance. Women in their 20 to 30 yr old suffer from sleep disturbance due to high level of time-based and strain-based work-interference into family. However, the quality of sleep among women aged 30-39 were affected by strain-based family-interference into work. Finally, women older than 40 yr had significantly disturbed sleep due to strain-based work-interference into family as well as time-based family interference into work. Our findings showed that sleep quality of working women might be disturbed by experiencing high level of work-family conflict. However, the effects of inter-role conflicts on sleep varied among different age groups.

Introduction: The study of sluggish cognitive tempo (SCT) arose largely from research carried out on attention deficit hyperactivity disorder (ADHD). This construct is defined by a range of behavioural symptoms such as the appearance of drowsiness, daydreaming, physical hypoactivity, little initiative, lethargy and apathy., Development: The construct of SCT is reviewed by means of recently published papers on its clinical characteristics, associated symptoms, evaluation, prevalence, aetiology, comorbidity, neuropsychological profiles and treatment. The latest studies propose that SCT should be understood as a cluster of symptoms that is distinct from ADHD. Although there is no clear consensus on the matter, the evidence is becoming increasingly more consistent and endows SCT with a high degree of external validity, associating it with internalising symptoms., Conclusions: We believe the different subtypes of ADHD must be grounded in attentional conceptual models. Hence, the attentional guidance network would be related with SCT, the vigilance or sustained attention network would be linked with the inattentive subtype of ADHD, and executive attention would be involved in the combined subtype of ADHD. The evidence obtained to date, including this review, supports the idea that SCT is an attention disorder distinct from ADHD but, like any dimensional disorder, it can overlap with it in around half the cases.

Introduction: According to the criteria of Hodges and Warlow, transient global amnesia is defined by sudden onset of isolated anterograde amnesia of spontaneous resolution within one to twenty-four hours. Its pathophysiological mechanisms are still uncertain., Methods: In a retrospective study, we have analyzed epidemiological, clinical and MRI data from twelve patients admitted to the only neurological department of French Polynesia for transient global amnesia corresponding to the criteria of Hodges and Warlow between January 2010 and December 2013., Results: The median age of the cohort was 61.5 (53-72), the sex ratio was 1. Ten patients had one or more cardiovascular risk factors, 3 had migraine headaches and 3 had anxiodepressive disorders. Among triggers found, the occurrence during the rest was noted in one case. Retrograde amnesia was observed in 42% of cases, repetitive questioning in 75% of cases, anxious bewilderment in 67% of cases and disorientation in 33% of cases. The median episode duration was 9 hours and the duration of hospitalization was 3 days. Three patients had a recurrence. MRI was abnormal in all patients and showed diffusion-weighted hyperintensities in right (n=8), left (n=3) and bilateral (n=1) hippocampi., Conclusion: Epidemiological, clinical and MRI data from our cohort are similar to those from the literature except for the highest prevalence of cardiovascular risk factors and the most frequent right hippocampus involvement. Transient global amnesia occurring exceptionally while sleeping was also observed in one of our patients., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

Introduction: The development of atypical features in rolandic epilepsy is part of a clinical spectrum of phenotypes that are variable, idiopathic and age-dependent, as well as having a genetically determined predisposition., Aim: To study the electroclinical characteristics suggesting an atypical development in rolandic epilepsy., Patients and Methods: A retrospective search was performed in 133 children diagnosed with atypical benign focal epilepsy (ABFE), Landau-Kleffner syndrome and continuous spike-wave during sleep (CSWS). Nine patients were selected, all of whom presented atypical clinical features and an electroencephalogram (EEG) pattern of electrical status epilepticus during sleep (ESES) in the course of their rolandic epilepsy., Results: The average age at onset of rolandic epilepsy was 5 years. Patients showed a deterioration of both their clinical features and their EEG recording one and a half years later, on average. ABFE was observed in three of them and CSWS in six. No cases of Landau-Kleffner syndrome were found. The EEG in wakefulness showed the focus to be in the left centrotemporal region in six patients and in three of them it was on the right-hand side. All the patients presented ESES in the EEG during sleep. An atypical pattern was observed in the regional ESES in three of the patients. Moreover, cognitive and behavioural disorders were detected due to deficits in specific learning areas, such as language, memory, attention and restlessness., Conclusions: The early onset of rolandic epilepsy, the appearance of new seizures with an increased frequency and the frontocentrotemporal focus in the EEG, which increases in frequency, both in wakefulness and in sleep, are all electroclinical characteristics of an atypical development.

Hepatic encephalopathy (HE) shows a wide spectrum of neuropsychiatric manifestations. A combined effort with neuropsychological and psychometric evaluation has to be performed to recognize the syndrome, whereas minimal HE (MHE) is largely under-recognized. Subtle symptoms of MHE can only be diagnosed through specialized neuropsychiatric testing. Early diagnosis and treatment may drastically improve the quality of life for many cirrhotic patients. Further research to gain better insight into the pathophysiology and diagnostic accuracy of HE will help determine future management strategies., (Copyright © 2015 Elsevier Inc.

Sleep deteriorates with age. The menopause is often a turning point for women's sleep, as complaints of insomnia increase significantly thereafter. Insomnia can occur as a secondary disorder to hot flashes, mood disorders, medical conditions, psychosocial factors, underlying intrinsic sleep disorders, such as obstructive sleep apnoea (OSA) or restless legs syndrome (RLS), or it can be a primary disorder. Since unrecognized OSA can have dramatic health-related consequences, menopausal women complaining of persisting sleep disturbances suggesting primary insomnia or intrinsic sleep disorders should be referred to a sleep specialist for a comprehensive sleep assessment. Patients suffering from primary insomnia will be preferentially treated with non-benzodiazepine hypnotics or melatonin, or with cognitive behavioural therapy. Insomnia related to vasomotor symptoms can be improved with hormone replacement therapy. Gabapentin and isoflavones have also shown efficacy in small series but their precise role has yet to be established. In patients suffering from OSA, non-pharmacological therapy will be applied: continuous positive airway pressure or an oral appliance, according to the severity of the disorder. In the case of RLS, triggering factors must be avoided; dopaminergic agonists are the first-line treatment for moderate to severe disease. In conclusion, persisting sleep complaints should be addressed in menopausal women, in order to correctly diagnose the specific causal disorder and to prescribe treatments that have been shown to improve sleep quality, quality of life and long-term health status., (Copyright © 2015 Elsevier Ireland Ltd.

Objectives: To prospectively determine the nature and rate of adverse drug reactions (ADRs) in children on antiepileptic drugs (AEDs) and to prospectively evaluate the effect of AEDs on behaviour., Setting: A single centre prospective observational study., Participants: Children (<18 years old) receiving one or more AEDs for epilepsy, at each clinically determined follow-up visit., Primary and Secondary Outcomes: Primary outcome was adverse reactions of AEDs. Behavioural and cognitive functions were secondary outcomes., Results: 180 children were recruited. Sodium valproate and carbamazepine were the most frequently used AEDs. A total of 114 ADRs were recorded in 56 of these children (31%). 135 children (75%) were on monotherapy. 27 of the 45 children (60%) on polytherapy had ADRs; while 29 (21%) of those on monotherapy had ADRs. The risk of ADRs was significantly lower in patients receiving monotherapy than polytherapy (RR: 0.61, 95% CI 0.47 to 0.79, p<0.0001). Behavioural problems and somnolence were the most common ADRs. 23 children had to discontinue their AED due to an ADR., Conclusions: Behavioural problems and somnolence were the most common ADRs. Polytherapy significantly increases the likelihood of ADRs in children., Trail Registration Number: EudraCT (2007-000565-37)., (Published by the BMJ Publishing Group Limited.

Objectives: Gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS) are highly prevalent in the general population, with significant symptom overlap, whereas the interaction between both remains poorly understood. We aim to identify the clinical and psychological factors that contribute toward the overlap of GERD and IBS., Patients and Methods: We carried out a case-control study among 806 GERD and 176 IBS patients from a health check-up cohort (n=2604). All participants were evaluated using the Reflux Disease Questionnaire score, the Pittsburgh Sleep Quality Index score, the Taiwanese Depression Questionnaire score, and the State-Trait Anxiety Inventory score. Endoscopic findings were classified according to the Los Angeles classification. IBS was diagnosed on the basis of Rome III criteria, and metabolic syndrome was defined by the National Cholesterol Education Program Adult Treatment Panel III definition., Results: Among the study population, 727 individuals had GERD, 97 individuals had IBS, and 79 individuals had a diagnosis of both GERD and IBS (GERD-I). GERD-I patients had more severe GERD symptoms compared with patients with GERD or IBS alone (P<0.0001). Moreover, GERD-I patients had more frequent healthcare-seeking behavior, decreased quality of sleep, and higher depression scores than patients with GERD (P<0.0001) or IBS alone (P<0.05). In addition, GERD-I patients had lower blood pressure, waist-to-hip ratio, and higher serum high-density lipoprotein levels than those with GERD alone (P<0.05)., Conclusion: GERD patients overlapping with IBS have different clinical and psychological profiles than those with GERD or IBS alone. Our study suggests that awareness of these symptom presentations will help optimize the treatment of these conditions.

Introduction: It is a well-known fact that epileptic seizures disrupt sleep, yet little information is available about sleep disorders according to the type of epileptic seizures., Materials and Methods: The sleep architecture of rats was evaluated in polysomnography recordings 36 hours after inducing partial and generalised epileptic seizures in them. The epileptic seizures were induced by applying 50-100 IU of sodium G penicillin in the amygdala of the temporal lobe., Results: Partial and generalised seizures triggered an increase in the latency of slow wave sleep (SWS) and rapid eye movement (REM) sleep. The number of episodes of the phases of wakefulness, SWS and REM sleep was reduced and the mean duration of the episodes of wakefulness and SWS increased, while that of REM sleep diminished. The total percentage of REM sleep diminished significantly. During the first period of light the partial and generalised seizures triggered an increase in wakefulness and a reduction in the phases of SWS and REM sleep. In the period of darkness, the SWS increased and wakefulness decreased, while there were no changes in REM sleep. In the second period of light, the percentages of the phases of wakefulness and SWS returned to control values and the percentage of REM sleep continued to be reduced., Conclusions: Changes in the structuring of sleep depend on the type of epileptic seizure that presents. Generalised epileptic seizures caused greater deterioration in REM sleep.

Fibromyalgia has a distinct pathophysiology involving central amplification of peripheral sensory signals. Core symptoms are chronic widespread pain, fatigue, and sleep disturbance. Most patients with fibromyalgia have muscle pain and tenderness, forgetfulness or problems concentrating, and significant functional limitations. Fibromyalgia is diagnosed using an updated set of clinical criteria that no longer depend on tender point examination; laboratory testing may rule out other disorders that commonly present with fatigue, such as anemia and thyroid disease. Patients with fibromyalgia should be evaluated for comorbid functional pain syndromes and mood disorders. Management of fibromyalgia should include patient education, symptom relief, and regular aerobic physical activity. Serotoninnorepinephrine reuptake inhibitors, tricyclic antidepressants, antiepileptics, and muscle relaxants have the strongest evidence of benefit for improving pain, fatigue, sleep symptoms, and quality of life. Multiple complementary and alternative medicine therapies have been used but have limited evidence of effectiveness. Opioids should be used to relieve pain in carefully selected patients only if alternative therapies are ineffective.

This is a review of the different complementary techniques that are useful for optimizing home mechanical ventilation (HMV). Airway clearance is very important in patients with HMV and many patients, particularly those with reduced peak cough flow, require airway clearance (manual or assisted) or assisted cough techniques (manual or mechanical) and suctioning procedures, in addition to ventilation. In the case of invasive HMV, good tracheostomy cannula management is essential for success. HMV patients may have sleep disturbances that must be taken into account. Sleep studies including complete polysomnography or respiratory polygraphy are helpful for identifying patient-ventilator asynchrony. Other techniques, such as bronchoscopy or nutritional support, may be required in patients on HMV, particularly if percutaneous gastrostomy is required. Information on treatment efficacy can be obtained from HMV monitoring, using methods such as pulse oximetry, capnography or the internal programs of the ventilators themselves. Finally, the importance of the patient's subjective perception is reviewed, as this may potentially affect the success of the HMV., (Copyright © 2014 SEPAR. Published by Elsevier Espana.

Objective: To examine the effectiveness of gabapentin and pregabalin in diminishing neuropathic pain and other secondary conditions in individuals with spinal cord injury (SCI)., Data Sources: A systematic search was conducted using multiple databases for relevant articles published from 1980 to June 2013., Study Selection: Controlled and uncontrolled trials involving gabapentin and pregabalin for treatment of neuropathic pain, with ≥3 subjects and ≥50% of study population with SCI, were included., Data Extraction: Two independent reviewers selected studies based on inclusion criteria and then extracted data. Pooled analysis using Cohen's d to calculate standardized mean difference (SMD), SE, and 95% confidence interval (CI) for primary (pain) and secondary outcomes (anxiety, depression, sleep interference) was conducted., Data Synthesis: Eight studies met inclusion criteria. There was a significant reduction in the intensity of neuropathic pain at <3 months (SMD=.96±.11; 95% CI, .74-1.19; P<.001) and between 3 and 6 months (SMD=2.80±.18; 95% CI, 2.44-3.16; P<.001). A subanalysis found a significant decrease in pain with gabapentin (SMD=1.20±.16; 95% CI, .88-1.52; P<.001) and with pregabalin (SMD=1.71±.13; 95% CI, 1.458-1.965; P<.001). A significant reduction in other SCI secondary conditions, including sleep interference (SMD=1.46±.12; 95% CI, 1.22-1.71; P<.001), anxiety (SMD=1.05±.12; 95% CI, .81-1.29; P<.001), and depression (SMD=1.22±.13; 95% CI, .967-1.481; P<.001) symptoms, was shown. A significantly higher risk of dizziness (risk ratio [RR]=2.02, P=.02), edema (RR=6.140, P=.04), and somnolence (RR=1.75, P=.01) was observed., Conclusions: Gabapentin and pregabalin appear useful for treating pain and other secondary conditions after SCI. Effectiveness comparative to other analgesics has not been studied. Patients need to be monitored closely for side effects., (Copyright © 2014 American Congress of Rehabilitation Medicine.

Traumatic brain injury (TBI) is a major health concern in industrialised countries. Sleep and wake disturbances are among the most persistent and disabling sequelae after TBI. Yet, despite the widespread complaints of post-TBI sleep and wake disturbances, studies on their etiology, pathophysiology, and treatments remain inconclusive. This narrative review aims to summarise the current state of knowledge regarding the nature of sleep and wake disturbances following TBI, both subjective and objective, spanning all levels of severity and phases post-injury. A second goal is to outline the various causes of post-TBI sleep-wake disturbances. Globally, although sleep-wake complaints are reported in all studies and across all levels of severity, consensus regarding the objective nature of these disturbances is not unanimous and varies widely across studies. In order to optimise recovery in TBI survivors, further studies are required to shed light on the complexity and heterogeneity of post-TBI sleep and wake disturbances, and to fully grasp the best timing and approach for intervention., (Copyright © 2014 Elsevier Masson SAS.

Unlabelled: The vast majority of Attention-deficit/hyperactivity disorder (ADHD) patients have other associated pathologies, with depressive symptoms as one of the most prevalent. Among the mediators that may participate in ADHD, melatonin is thought to regulate circadian rhythms, neurological function and stress response. To determine (1) the serum baseline daily variations and nocturnal excretion of melatonin in ADHD subtypes and (2) the effect of chronic administration of methylphenidate, as well as the effects on symptomatology, 136 children with ADHD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision: DSM-IV-TR criteria) were divided into subgroups using the "Children's Depression Inventory" (CDI). Blood samples were drawn at 20:00 and 09:00 h, and urine was collected between 21:00 and 09:00 h, at inclusion and after 4.61 ± 2.29 months of treatment. Melatonin and its urine metabolite were measured by radioimmunoassay RIA. Factorial analysis was performed using STATA 12.0. Melatonin was higher predominantly in hyperactive-impulsive/conduct disordered children (PHI/CD) of the ADHD subtype, without the influence of comorbid depressive symptoms. Methylphenidate ameliorated this comorbidity without induction of any changes in the serum melatonin profile, but treatment with it was associated with a decrease in 6-s-melatonin excretion in both ADHD subtypes., Conclusions: In untreated children, partial homeostatic restoration of disrupted neuroendocrine equilibrium most likely led to an increased serum melatonin in PHI/CD children. A differential cerebral melatonin metabolization after methylphenidate may underlie some of the clinical benefit.

Patients with Parkinson's disease (PD) display significant sleep disturbances and daytime sleepiness. Dopaminergic treatment dramatically improves PD motor symptoms, but its action on sleep remains controversial, suggesting a causal role of nondopaminergic lesions in these symptoms. Because the pedunculopontine nucleus (PPN) regulates sleep and arousal, and in view of the loss of its cholinergic neurons in PD, the PPN could be involved in these sleep disorders. The aims of this study were as follows: (1) to characterize sleep disorders in a monkey model of PD; (2) to investigate whether l-dopa treatment alleviates sleep disorders; and (3) to determine whether a cholinergic PPN lesion would add specific sleep alterations. To this end, long-term continuous electroencephalographic monitoring of vigilance states was performed in macaques, using an implanted miniaturized telemetry device. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine treatment induced sleep disorders that comprised sleep episodes during daytime and sleep fragmentation and a reduction of sleep efficiency at nighttime. It also induced a reduction in time spent in rapid eye movement (REM) sleep and slow-wave sleep and an increase in muscle tone during REM and non-REM sleep episodes and in the number of awakenings and movements. l-Dopa treatment resulted in a partial but significant improvement of almost all sleep parameters. PPN lesion induced a transient decrease in REM sleep and in slow-wave sleep followed by a slight improvement of sleep quality. Our data demonstrate the efficacy of l-dopa treatment in improving sleep disorders in parkinsonian monkeys, and that adding a cholinergic PPN lesion improves sleep quality after transient sleep impairment., (Copyright © 2014 the authors 0270-6474/14/349124-10$15.00/0.)

Background: Regular short and long sleep durations are associated with increased mortality and morbidity. While previous research shows significant sleep disparities between people with and without disabilities, less is known about the association between different types of disability and high-risk sleep using nationally representative data., Objective: We examine the association between short and long sleep durations and having a work disability or an impairment in sensory, cognitive, or physical functioning among a nationally representative sample of working-age adults in the United States., Methods: We estimate multinomial logistic regression models using data from the 2003-2012 American Time Use Survey to identify how different types of disabling conditions--net of other sociodemographic factors--relate to the likelihood of reporting short (6 h or fewer) or long (9 h or more) sleep, versus mid-range (between 6 and 9 h) sleep., Results: For respondents with work disabilities versus those without work disabilities, the relative risk of short and long sleep is 1.4 and 1.5 times (respectively) that of those with mid-range sleep. The risk of short and long sleep durations is also higher among respondents with cognitive, physical, or multiple impairments., Conclusions: Individuals with disabilities are less likely than those without disabilities to have optimal sleep durations. These results demonstrate the importance of health promotion services among this population, with specific attention to sleep hygiene interventions., (Copyright © 2014 Elsevier Inc.

Background: Dysmenorrhea is quite frequent and may affect the daily activities especially during the early years of adolesence. This study aimed to evaluate the prevalence of dysmenorrhoea, its impact, and the management strategies adopted., Methods: This cross-sectional study was done with 356 consenting females studying at Mohiuddin Islamic University, Mirpur Azad Kashmir, between 18-25 years of age, with regular menstrual cycles and normal abdomino-pelvic ultrasound and not taking any medication. Information was gathered regarding age, residence, menstrual history, body mass index (BMI), associated symptoms, remedies used and days lost., Results: A total of 56.1% females had dysmenorrhoea. The mean age of participants was 21.01±1.54 years, mean age of menarche was 12.9±1.65 years, mean duration of menstrual flow was 4.75±1.27 days and mean BMI was 24.1±1.6. 17% of the participants were dieting and 26% had daily milk intake. 25% reported being absent due to pain and number of days lost was 1.5±1.0 days. Common symptoms associated with the dysmenorrhoea were difficulty concentrating in 65%, less involvement in social activities and sleep affected in 64%, mood disturbances in 58% and headache in 56%. Household remedies for dysmenorrhea were used by 43% and 66% used analgesics and only 4% sought medical advice for pain., Conclusion: Dysmenorrhoea is a very common problem affecting academic performance and limiting daily activities requiring appropriate intervention.

The pain associated with spondyloarthritis (SpA) can be intense, persistent and disabling. It frequently has a multifactorial, simultaneously central and peripheral origin, and may be due to currently active inflammation, or joint damage and tissue destruction arising from a previous inflammatory condition. Inflammatory pain symptoms can be reduced by non-steroidal anti-inflammatory drugs, but many patients continue to experience moderate pain due to alterations in the mechanisms that regulate central pain, as in the case of the chronic widespread pain (CWP) that characterises fibromyalgia (FM). The importance of distinguishing SpA and FM is underlined by the fact that SpA is currently treated with costly drugs such as tumour necrosis factor (TNF) inhibitors, and direct costs are higher in patients with concomitant CWP or FM than in those with FM or SpA alone. Optimal treatment needs to take into account symptoms such as fatigue, mood, sleep, and the overall quality of life, and is based on the use of tricyclic antidepressants or selective serotonin reuptake inhibitors such as fluoxetine, rather than adjustments in the dose of anti-TNF agents or disease-modifying drugs.

Background: Poor sleep is prevalent in patients with systemic inflammatory disorders, including rheumatoid arthritis, and, in addition to fatigue, pain, depression and inflammation, is associated with an increased risk of co-morbidity and all-cause mortality. Whereas non-pharmacological interventions in patients with rheumatoid arthritis have been shown to reduce pain and fatigue, no randomized controlled trials have examined the effect of non-pharmacological interventions on improvement of sleep in patients with rheumatoid arthritis. The aim of this trial was to evaluate the efficacy of an intermittent aerobic exercise intervention on sleep, assessed both objectively and subjectively in patients with rheumatoid arthritis., Methods/design: A randomized controlled trial including 44 patients with rheumatoid arthritis randomly assigned to an exercise training intervention or to a control group. The intervention consists of 18 session intermittent aerobic exercise training on a bicycle ergometer three times a week. Patients are evaluated according to objective changes in sleep as measured by polysomnography (primary outcome). Secondary outcomes include changes in subjective sleep quality and sleep disturbances, fatigue, pain, depressive symptoms, physical function, health-related quality of life and cardiorespiratory fitness., Discussion: This trial will provide evidence of the effect of intermittent aerobic exercise on the improvement of sleep in patients with rheumatoid arthritis, which is considered important in promotion of health and well-being. As such, the trial meets a currently unmet need for the provision of non-pharmacological treatment initiatives of poor sleep in patients with rheumatoid arthritis., Trial Registration: ClinicalTrials.gov Identifier: NCT01966835.

Introduction: Sleep disorders are frequent among patients with epilepsy and are correlated with a poorer quality of life., Aims: To evaluate the prevalence of sleep disorders in patients with refractory and non-refractory focal epilepsy, and to explore the influence of these alterations on the quality of life of these patients., Patients and Methods: An epidemiological, controlled, cross-sectional study was conducted in 150 outpatient neurology services. Patients who had been treated with two antiepileptic drugs since the onset of the disease (18-55 years) were recruited for the study., Results: The sample included 237 patients with non-refractory focal epilepsy and 264 patients with refractory focal epilepsy. Twenty-two per cent of the non-refractory epilepsy group and 45% of the group with refractory epilepsy (p < 0.0001) suffered from some sleep disorder. The patients with refractory epilepsy had a poorer quality of life (p < 0.001) as measured with the quality of life questionnaire QOLIE-10. A positive significant correlation was observed between quality of life and quality of sleep, in both chronic insomnia (r = 0.65; p < 0.0001) and excessive daytime sleepiness (r = 0.43; p < 0.0001)., Conclusions: Sleep disorders are more frequent in refractory than in non-refractory epilepsy, and affect the patients' quality of life.

Pediatric insomnia is an extrinsic sleep disorder subdivided into two categories: behavioral insomnia and insomnia related to medical, neurological, and psychiatric diseases. This review will cover several types of insomnia, comorbidities and specific pediatric therapies according to clinical characteristics and age. Behavioral insomnia should be differentiated from pediatric insomnia due to medical conditions, mostly occurring during the first year of life. Multiple night awakenings and diurnal hypersomnolence are strong indicators of insomnia due to medical conditions. Insomnia during adolescence and pediatric insomnia associated with psychiatric comorbidity, cognitive disabilities and epilepsy, will be discussed in terms of diagnosis, clinical features and implications for treatment.

Objective: We report a focal morphofunctional brain impairment within the left temporopolar cortex in a patient with a posttraumatic hypersomnia. This case may contribute to better understanding the possible pathophysiological mechanism for posttraumatic hypersomnia.

Background: Fibromyalgia is a common and debilitating condition. The cardinal feature of fibromyalgia is musculoskeletal pain, usually accompanied by other problems, such as fatigue, sleep disturbance and cognitive difficulties. Fibromyalgia commonly coexists with other chronic illnesses and can result in poorer outcomes if untreated., Objective: The objective of this review is to discuss when fibromyalgia should be considered as a diagnosis, how it is diagnosed, the current understanding of the pathophysiology of fibromyalgia and the management strategies available., Discussion: The features of fibromyalgia are similar to those of many other chronic illnesses, sometimes resulting in diagnostic confusion. Fibromyalgia can co-exist with other disorders and it is important to consider the possibility of fibromyalgia contributing to symptoms in any chronically ill patient.

Objectives: The multiple sleep latency test (MSLT) has been employed extensively in clinical and research settings as a gold standard for objectively measuring sleepiness. In a general population or in a variety of work settings, however, a more convenient, rapidly administered measuring method is preferable. We examined the potential utility of pupillometry by comparing its objective measures, pupillary unrest index (PUI) and relative pupillary unrest index (RPUI), with MSLT-derived sleep latency (SL)., Methods: The study cohort comprised 45 patients (39 males, 6 females, mean age 38.9 ± 11.3 years) referred to the Sleep Disorders Center for the two-nap SL test. SL was measured twice before noon, and pupillometric measurement was performed immediately before each SL test. Subjective sleepiness was measured by using the Epworth Sleepiness Scale (ESS)., Results: The association between PUI and SL was significant and far closer than that between RPUI and SL. A significant difference was observed between the two groups, based on each subject's experience of drowsy driving accidents over the past 3 years in the PUI and RPUI, as well as in SL. The subjective sleepiness measure, ESS, did not relate to any other physiological sleepiness measures., Conclusions: In our study cohort, the pupillometric sleepiness measure, PUI, was significantly correlated with, and behaved in a manner equivalent to, MSLT-derived SL in clinically sleepy patients. However, several points remain to be carefully examined before applying pupillometry for screening sleepiness in a general population, or in occupational settings.

The purpose of this pilot study was to evaluate the feasibility and effectiveness of a yoga program as an adjunctive therapy for improving post-traumatic stress disorder (PTSD) symptoms in Veterans with military-related PTSD. Veterans (n = 12) participated in a 6 week yoga intervention held twice a week. There was significant improvement in PTSD hyperarousal symptoms and overall sleep quality as well as daytime dysfunction related to sleep. There were no significant improvements in the total PTSD, anger, or quality of life outcome scores. These results suggest that this yoga program may be an effective adjunctive therapy for improving hyperarousal symptoms of PTSD including sleep quality. This study demonstrates that the yoga program is acceptable, feasible, and that there is good adherence in a Veteran population., (Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.)

Background: There is currently no instrument to systematically assess the range of symptoms/problems and their bothersomeness in patients with chronic non-cancer pain (CNPN). Systematic assessment and prioritizing may target treatments and improve outcomes., Methods: The authors developed a checklist of symptoms and problems, the Copenhagen Symptom Checklist (CSC), presented clinically by patients. Fifty-three items representing biological, psychological and social areas were selected. Symptom/problem severity was rated on a 5-point scale anchored at 0 = 'not at all' and 4 = 'severe'. Patients ranked the five most bothersome symptoms/problems and could add five open-ended items. Patients completed the CSC after the first visit at the multidisciplinary pain centre., Results: One hundred and twelve consecutive patients completed the CSC. Eighty-nine percent scored pain as rather severe or very severe (score = 3 plus score = 4), followed by reduction in physical activity (67%), fatigue (66%) and sleep disturbance (53%). Pain and fatigue, but not reduction in physical activity, were given highest priority. Cognitive problems were important to a third of the patients. Depressive symptoms, cognitive problems and worry explained 17.5% of the total variance. Patients filled in the CSC without important loss of information, but a minority prioritized more than three areas or used the free text alternative., Conclusions: Patients prioritized pain and fatigue as the most burdensome symptoms, but reduction in physical activity and sleep problems were also highly ranked. Patients were positive to the idea of symptom reporting; however, the 53-item number in this version of CSC is larger than may be necessary., (© 2013 The Acta Anaesthesiologica Scandinavica Foundation.

Purpose: In contrast to EEG, which has guidelines for interpretation and a plethora of textbooks, the full range of activity seen in magnetoencephalography (MEG) has not been fleshed out. Currently, magnetoencephalographers apply criteria for EEG waveforms to MEG signals based on an assumption that MEG activity should have morphology that is similar to EEG. The purpose of this article was to show the characteristic MEG profile of positive occipital sharp transients of sleep., Methods: Simultaneous MEG-EEG recordings of two cases are shown., Results: In both the cases, the morphologic features of positive occipital sharp transients of sleep in MEG vary and sometimes mimic epileptic spikes., Conclusion: This report raises a caution that a normal variant may have an even more epileptic appearance on MEG than on EEG. Using the simultaneously recorded EEG to avoid misinterpretation of spikey-looking positive occipital sharp transients of sleep in MEG is a natural and prudent practice.

Background: Sleep disorders are common in patients with advanced Parkinson's disease (PD). Nocturnal akinesia and sleep fragmentation frequently coexist with daytime sleepiness, influencing daytime functioning. Levodopa/carbidopa intestinal gel (LCIG) infusion has been shown to improve motor complications in advanced PD, and preliminary findings suggest that sleep might improve following LCIG infusion., Objective: To analyze the impact of LCIG infusion on sleep symptoms and daytime sleepiness in patients with PD., Methods: Twelve consecutive patients with PD completed the PD-Sleep-Scale-version-2 (PDSS-2) and the Epworth-Sleepiness-Scale (ESS) at baseline and after 2-4 months of LCIG treatment. Activities of daily living, motor symptoms and complications were assessed with the Unified-PD-rating-Scale section II, III, and IV., Results: Nocturnal sleep improved substantially in all patients switched to LCIG infusion. PDSS-2 total score and subscores for 'Disturbed sleep', 'Motor symptoms at night', and 'PD symptoms at night' were significantly reduced. ESS measures of daytime sleepiness also improved. Motor complications and activities of daily living improved significantly with LCIG., Conclusion: Subjective measures of sleep quality and daytime sleepiness improve in patients with advanced PD undergoing LCIG infusion. Further studies with a larger number of patients and polysomnographic recordings are needed to confirm the beneficial effect on sleep and clarify the underlying mechanisms., (© 2013 John Wiley & Sons A/S.)

Introduction: Multiple system atrophy (MSA) is a sporadic and rapidly progressive neurodegenerative disorder of poor prognosis, characterised clinically by any combination of parkinsonian, autonomic, cerebellar, or pyramidal signs. We report our experience in movement disorders consultation concerning the clinical presentation and the course of MSA in Moroccan patients., Methods: A retrospective review of the medical records of 17 patients with diagnosis of MSA seen in our outpatient clinic from January 2007 to December 2010., Results: In our 17 patients, 76.5% were men and the mean age of onset was 52±9 years. MSA-P was the major clinical phenotype (82.4%). Eleven patients (64.7%) were classified as having probable MSA and six patients (35.3%) as possible MSA. Dysautonomic features were detected in all patients; urinary symptoms were found in 76.5% of cases and orthostatic hypotension in 64.7%. Treatment regimen included l-Dopa with a mean daily dose of 621.4±346.8mg/day and symptomatic treatment of dysautonomia. The mean duration of disease evolution was of 4.7±1.9 years., Discussion: Our results show a male predominance and an early age of disease onset. MSA-P was the predominant subtype. Our results are similar to the European MSA series., Conclusion: Multicentre studies are needed to better characterise MSA in Morocco given the rarity of this disease., (Copyright © 2012 Elsevier Masson SAS.

Traumatic brain injury (TBI) has emerged as a major cause of morbidity among U.S. servicemembers who have served in Iraq and Afghanistan. Even mild TBI (mTBI) can result in cognitive impairments that can affect the community reintegration of Veterans postdeployment. The purpose of this study was to explore the needs and concerns of combat Veterans with mTBI to provide support for an mTBI-specific conceptual model (Conceptual Model in the Context of mTBI) derived from Ferrans et al.'s health-related quality of life model and the TBI literature. Content analysis of qualitative interview data was conducted using a thematic matrix with a predetermined code list. Data saturation was achieved after interviews with eight male Veterans. Six key categories and predominant themes emerged: cognitive impairments, physical symptoms, emotions and behaviors, instrumental activities of daily living, interpersonal interactions, and community reintegration. Findings provide preliminary support for a new, context-specific conceptual model that has the potential to identify areas for future interventions to enhance community reintegration of combat Veterans with mTBI.

Fatigue is the most common and debilitating symptom in multiple sclerosis (MS) and is believed to be distinctly different from fatigue seen in other chronic conditions. It can affect a patient's mood, sleep and have a detrimental effect on their quality of life. In the recent years much literature has emerged in an attempt to elucidate the potential causes and treatment of this common symptom. This review article aims to examine the most recent theories on the pathophysiology of fatigue in MS as well as its association with sleep and depression. We describe the pharmacological and non-pharmacological approaches to its treatment and propose a multidisciplinary, patient enabled and individualised manner to the management of fatigue in MS., (Copyright © 2012 Elsevier B.V.

Background: Parkinson's disease (PD) occurs more frequently in men than in women and a higher risk for PD development in males compared with females has been hypothesized, suggesting gender may be a significant factor in the development and progression of parkinsonism. To date, gender differences in non-motor symptoms are under-reported., Objective: To assess gender differences in motor and non-motor symptoms among Sardinian PD patients., Methods: One hundred fifty-six (91 male and 65 female) consecutive Sardinian PD outpatients were included in this analysis. Modified Hoehn and Yahr scale and UPDRS were used to assess motor symptoms, while non-motor disturbances were evaluated with the non-motor symptoms scale (NMSS). Presence of depression, anxiety and other iatrogenic behavioral disorders was also investigated. In order to determine how gender differences could be specific to PD, 132 age-matched normal controls were assessed with the NMSS., Results: Women were more likely than men to present with tremor as initial symptom (p<.025) and worse UPDRS instability score (p<.02). NMSS score in females was significantly higher than that in males (p<.018). A significantly higher severity in cardiovascular (p<0.002), sleep/fatigue (p<.018) and mood/apathy (p<.001) domains was observed in female PD patients, while the sexual dysfunction domain was reported with a significantly higher score in male patients (p<.017). Fatigue (p<.03), lack of motivation (p<.015) and sadness (p<.009) were observed significantly more frequent in females, while altered interest in sex was noted as more common in males (p<.001). Frequency of depression (p<.011) and anxiety (p<.001) was significantly higher in females, while male patients had increased frequency of compulsive sexual behaviors (p<.05). There was a significantly higher frequency of non-motor symptoms in eight domains in both male and female PD patients compared with controls (p<.001, for all comparisons, with the exception of urinary disturbances in females: p<.004). Only sexual dysfunctions were not significantly higher in male and female PD patients compared with controls., Discussion: The present study highlights the role of gender differences associated with the occurrence of motor and non-motor disorders and our findings indicate that spectrum and severity of non-motor symptoms may present with different gender distribution in PD patients, suggesting a possible sex-related effect., (Copyright © 2012 Elsevier B.V.

Traumatic brain injury is a frequent condition worldwide, and sleep-wake disturbances often complicate the course after the injuring event. Current evidence suggests that the most common sleep-wake disturbances following traumatic brain injury include excessive daytime sleepiness and posttraumatic hypersomnia, that is, increased sleep need per 24 h. The neuromolecular basis of posttraumatic sleep pressure enhancement is not entirely clear. First neuropathological and clinical studies suggest that impaired hypocretin (orexin) signalling might contribute to sleepiness, but direct or indirect traumatic injury also to other sleep-wake modulating systems in the brainstem and the mesencephalon is likely. Posttraumatic insomnia may be less common than posttraumatic sleepiness, but studies on its frequency revealed conflicting results. Furthermore, insomnia is often associated with psychiatric comorbidities, and some patients with posttraumatic disruption of their circadian rhythm may be misdiagnosed as insomnia patients. The pathophysiology of posttraumatic circadian sleep disorders remains elusive; however, there is some evidence that reduced evening melatonin production due to traumatic brain damage may cause disruption of circadian regulation of sleep and wakefulness.
