Background: Headaches are frequent neurological disorders that are yet to be unveiled and treated comprehensively worldwide. Bearing in mind that the distribution of headache subtypes in neurology clinics (NC) is essential for planning appropriate diagnostic and therapeutic approaches, the primary goals of this multi-centric study are to carry out inter-regional comparisons by using current diagnostic criteria with evaluations of neurologists to delineate headache burden. Methods: A cross-sectional study between April 1 and May 16, 2022 was conducted with the participation of 13 countries from the Middle East, Asia, and Africa. Patients were included in the study on a specific day each week during five consecutive weeks. All volunteers over the age of 18 and whose primary cause for admission was headache were examined. The patients admitted to NC or referred from emergency services/other services were evaluated by neurologists by means of the International Classification of Headache Disorders (ICHD-3) criteria. Results: Among the 13,794 patients encountered in NC, headache was the primary complaint in 30.04%. The headache patients' mean age was 42.85 ± 14.89 (18–95 years), and 74.3% were female. According to the ICHD-3 criteria, 86.7% of the main group had primary headache disorders, 33.5% had secondary headaches, 4% had painful cranial neuropathies along with other facial and headaches, and 5.2% had headaches included in the appendix part showing some overlapping conditions. While the most common primary headache was migraine without aura (36.8%), the most common secondary headache was medication-overuse headache (MOH) (9.8%). Headaches attributed to COVID-19, its secondary complications, or vaccines continue to occur at rates of 1.2%-3.5% in current neurology practice. Pain severity was significantly lower in Ivory Coast and Sudan than in Türkiye, Turkish Republic of Northern Cyprus, Iran, Egypt, Senegal, Tatarstan, and Azerbaijan (p < 0.001). Conclusions: The study showed that migraine is still the most common motive for admissions to NC in different regions. Furthermore, MOH, an avoidable disorder, is the most common secondary headache type and appears to be a significant problem in all regions. Remarkably, pain perception differs between regions, and pain intensity is lower in Africa than in other regions. [ABSTRACT FROM AUTHOR]

Background & Objective: The 28-item General Health Questionnaire (GHQ-28) consists of 4 subscales.Validation of this questionnaire has been carried out by several studies conducted in Iran. Despite the multiplicity of researches which investigated the sensitivity, specificity and reliability of this questionnaire in Iran, few studies have investigated its factor structure. However, it is important to consider if Persian translations of GHQ-28 will indicate the same 4 factors as demonstrated in forign investigations. the aim of the current research was to assess the reliability, validity and the factor structure of the Persian version of GHQ-28.Materials & Methods: The current study was designed based on a survey method. A sample of 415 employees in Kerman hospitals participated in this study and completed the questionnaires.Results: The results showed that GHQ has an appropriate internal consistency for assessing the general health in this sample. Factor analysis using principal component method identified 4 factors in participants’ responses, and these 4 factors accounted for 60% of the total variance. The correlation between GHQ total scores and the Pitsburg sleep quality index was significant at a level smaller than 0.001.Conclusion: According to the evidence of this research it is concluded that explorative factor analysis identifies four factors in the participants’ responses and the fact that this questionnire has an appropriate internal consistency and an adequate validity for the assessment of general health in this sample.

Objective: Modern contraceptive methods have been very effective in family planning and well-being. The injectable contraceptives, though effective, had been discontinued by some users because of side effects like abnormal menstrual bleeding and weight gain. This study compared the pattern of menstrual bleeding and weight gain in users of Depot Medroxyprogesterone Acetate (DMPA) and Norethisterone-Enanthate (Noristerat) in Sagamu. Method: A retrospective study of 323 patients who used either DMPA or Noristerat over a 7-year period (January 2007 to December 2013). Data extracted from case notes included bio-data, parity, previous contraceptive methods and reasons for discontinuation of the contraceptives. Clients' weights, pattern of menstrual cycle and side effects were also documented for the ï€rst, second and third visits, and up to 1 year after commencing the injectable contraceptives. Results: The mean age of the participants was 32.72± 5.47 years. About 13.5% experienced no change in their menstrual cycle, but 55.9% and 58.9% of those who used Noristerat and DMPA respectively, had amenorrhoea by the end of one year. The mean weight was 62.89kg±12.84 for Noristerat group and 0.93kg±9.94 for DMPA group at commencement and 65.15kg±13.70 for Noristerat group and 64.05kg±10.30 for DMPA group at the end of one year. There was significant weight gain (p

Objective: Cognitive problems in idiopathic intracranial hypertension (IIH) is generally overlooked in the presence of disabling headache and threat to visual function. The aim of this study was to search for cognitive deficits in patients with IIH using neuropsychologic tests in addition to P300 potential recordings to assess cognition related brain activity., Methods: Fifty IIH patients were examined using Montreal Cognitive Assessment Test, Stroop Test and Visual Aural Digit Span Test to measure different domains of cognition at the time of diagnosis. P300 potentials were recorded by using an oddball paradigm. Hospital Anxiety and Depression Scale was used to determine anxiety and depression. Quality of life (QoL) was assessed by SF-36. The results were compared with fifty healthy controls with matching age, gender and body mass index., Results: Neuropsychologic tests revealed wide cognitive impairment including attention, working memory, executive function, naming, language, delayed recall and orientation in IIH patients. In addition, quality of life was affected in the sub-parameters of general health perceptions, emotional role functioning, vitality, mental health and bodily pain. P300 potential latencies were long and the amplitudes were reduced indicating deficits in attention and working memory. Anxiety scores were high, and health-related QoL was low mainly involving vitality, emotional and mental health. Cognitive dysfunction was not correlated with the levels of anxiety and the correlation with headache severity was mild., Conclusion: A multidomain cognitive decline mainly involving attention and working memory was recorded in IIH patients. It was not correlated with anxiety and only a mild correlation with headache severity was present which may indicate a casual relationship between raised intracranial pressure and cognitive deficits. Screening is important as neuropsychological rehabilitation might be relevant in these patients., (© 2024. The Author(s) under exclusive licence to Belgian Neurological Society.)

Introduction: The study aimed to adapt the "Athens Insomnia Scale" developed by Soldatos et al. into Turkish and to conduct validity and reliability analysis., Methods: This research was conducted on 215 patients with insomnia complaints and applied to Family Medicine, Neurology (Sleep Polyclinic), and Psychiatry outpatient clinics. Introductory Information Form, 8-item Athens Insomnia Scale, and Pittsburg Sleep Quality Index were administered to the participants. After the language adaptation of the scale, Cronbach's alpha value was used as the consistency coefficient for reliability analysis. Exploratory factor analysis was examined for structural validity, and correlation coefficients between the Athens Insomnia Scale and its subscales and the Pittsburg Sleep Quality Index were examined for concurrent validity., Results: Cronbach's alpha coefficient was calculated as 0.87. "Kaiser-Meyer-Olkin value was calculated for factor analysis." In the Exploratory Factor Analysis, a two-factor structure with eigenvalues >1.0 and explaining 73.4% of the variance was obtained. According to the Exploratory Factor Analysis results for the Atina Insomnia Scale, the absolute value of the factor loadings of the eight items ranged between 0.650 and 0.865. The correlation coefficients between the total score and sub-dimensions of the Athens Insomnia Scale and the Pittsburg Sleep Quality Index-a scale assessing sleep quality were between 0.489-0.725 (p<0,01). For discriminant validity, Athens Insomnia Scale discriminated well between patients and healthy volunteers (Z=2.630, p=0,009)., Conclusion: The Athens Insomnia Scale has been shown to have adequate reliability and validity in Turkish., Competing Interests: Conflict of Interest: The authors declared that there is no conflict of interest., (Copyright: © 2024 Turkish Neuropsychiatric Society.)

Background: Calcitonin gene-related peptide (CGRP) plays a dominant role in migraine. This prospective study was designed to investigate CGRP levels in patients with idiopathic intracranial hypertension (IIH) and compare the results of migraine patients and healthy controls (HC). As a second objective, CGRP levels obtained from IIH patients defining sustained headache after the resolution of papilledema were compared with those not defining post-IIH headache., Methods: Thirty-six patients with IIH, 36 with episodic migraine (EM), 18 with chronic migraine (CM), and 36 HC were included in the study. CGRP levels were studied from blood samples obtained from the antecubital vein by using a commercial ELISA kit., Results: Serum CGRP levels of the patient groups were significantly higher than the HC (p < 0.001). As compared with controls, both CM (p Adj<0.001) and IIH (p Adj=0.039) had significantly increased levels of CGRP. Levels recorded from EM patients did not differ from the HC (p Adj=0.661). In 16 IIH patients, persistent headache was reported after the normalization of intracranial pressure (ICP). Twenty patients did not report post-IIH headaches. Comparison of serum CGRP levels of these two groups revealed significantly higher CGRP levels in patients with sustained headaches obtained from blood samples both at the initial and control visit (p Adj <0.001)., Conclusions: CGRP levels of the patient groups were higher than the HC. High levels recorded in patients with IIH indicates the role of CGRP in IIH related headache and even higher levels in patients with sustained headache after normalization of ICP strengthens this finding., Competing Interests: Declaration of Competing Interest The authors declare that they have no competing interests., (Copyright © 2024 Elsevier B.V.

Objective: The thromboinflammatory process is considered to play a role in the pathogenesis and prognosis of cerebral sinus vein thrombosis (CSVT). The purpose of the study was to compare the thromboinflammatory parameters between individuals with CSVT and healty controls. Additionally, the study sought to compare these parameters among CSVT subgroups with and without haemorrhage, as well as with and without papilledema. Furthermore, the investigation also aimed to identify which parameters had a more significant impact on the risk of hemorrhage and the development of papilledema in CSVT., Methods: Thromboinflammatory parameters were compared retrospectively between the CSVT group of 88 patients and 80 age- and sex-matched healthy controls, and in the CSVT subgroups with (n = 35) /without hemorrhage (n = 53) and with (n = 52) /without papilledema (n = 36) after ethics committee approval. In both groups, parameters contributing to the risk of hemorrhage and papilledema development were determined by univariate and multivariate analyses., Results: Regarding the risk of hemorrhage in CSVT patients, the most significant factors included hematocrit of <30.2 (%), mean platelet volume of ≤8.9 fL, neutrophil count of >5600, and hsCRP of >9 mg/L. Regarding the risk of papilledema development, the most important risk factors were age of ≤49, presence of vomiting, presence of blurred vision, HDL of >47 mg/dL, and D-dimer of >178 ng/mL., Conclusion: It was suggested that evaluating serum thromboinflammatory parameters, as well as demographic characteristics and neurological examination findings, had a critical role regarding prognosis and predictive factors in CSVT., (Copyright © 2023 Elsevier B.V.

Background: Ocular myasthenia gravis (OMG) constitutes 15% of all myasthenia gravis patients., Methods: One hundred eight patients with OMG followed-up for over 36 months were retrospectively evaluated regarding factors associated with remission. Demographic features, neuro-ophthalmologic findings at onset, acetylcholine receptor (AChR Ab) and muscle-specifc tyrosine kinase antibodies (MuSK Ab), thymic status, single fiber electromyography (SFEMG) results were the variables considered., Results: Median age of disease onset was 57 years (range 18-82 years). Clinical features at onset was isolated ptosis in 55 (50.9%) and isolated diplopia in 33 (30.6%) patients. Combined ptosis and diplopia were present in 20 (18.5%) patients. Among 75 patients with ptosis, it was unilateral in 65 (86.7%) and bilateral in 10 (13.3%). AChR Abs were found in 66 (61.1%) and MuSK Abs in 2 (1.9%) patients. SFEMG abnormality was detected in 74 (68.5%) patients. Thymoma was present in 16 (14.8%) and thymic hyperplasia in 6 (5.6%) patients. Forty-one patients (37.9%) had been treated with pyridostigmine alone. Sixty-seven (62%) patients were given immunosupressive drugs. In 53 (49.1%) prednisone was used and in 14 (12.9%) patients it was combined with azathioprine. Thymectomy was performed in all 16 patients with thymoma. Complete stable remission (CSR) was achieved in 49 (45.4%) patients. Fifty-nine (54.6%) patients had reached minimal manifestation (MM) status; 32 (29.6%) having a status of MM-1 and 27 (25%) a status of MM-3., Conclusions: The presence of AchR Abs (p = 0.034) and an abnormal SFEMG (p = 0.006) at onset as increased risk factors for the presence of ongoing signs necessitating medical treatment., (© 2022.

Vestibular migraine (VM) is accepted as the most common cause of spontaneous episodic vertigo. In most patients, vestibular symptoms follow migraine headaches that begin earlier in life. The aim of this multicenter retrospective study was to find out the differences between migraine patients without any vestibular symptoms (MwoV) and VM patients and to delineate the specific clinical features associated with VM. MwoV and VM patients were compared regarding demographic features, migraine headache years, headache attack frequency, intensity, symptoms associated with headache and vertigo attacks, presence of menopause, history of motion sickness and family history of migraine. Four-hundred and forty patients with MwoV and 408 patients with VM were included in the study. Migraine with aura was more frequent in patients with MwoV (p = 0.035). Migraine headache years was longer (p < 0.001) and headache intensity was higher in patients with VM (p = 0.020). Aural fullness/tinnitus was more common in patients with VM (p < 0.001) when all other associated symptoms were more frequent in patients with MwoV (p < 0.001) as well as attack triggers (p < 0.05). Presence of menopause and motion sickness history was reported more frequently by VM patients (p < 0.001). Logistic regression analysis indicated that longstanding history of migraine with severe headache attacks, aural fullness/tinnitus accompanying attacks, presence of menopause, previous motion sickness history were the differentiating clinical features of patients with VM., (© 2023.

Background: Healthcare-associated infections (HAIs) are a significant threat in healthcare settings. Since nurses have the most day-to-day contact with patients, their knowledge about infection control (IC) practices is crucial in preventing HAIs. We therefore conducted a study to assess the knowledge and awareness of IC practices amongst nurses across hospitals in India., Methods: An online survey-based, cross-sectional, descriptive study for nurses was conducted in July-August 2021, through a multiple-choice questionnaire, administered via a web-based link across 13 hospitals from various cities of India. Five different aspects of IC knowledge were assessed including general IC, standard precautions, transmission-based precautions, bundle care knowledge, and COVID-19 related knowledge., Results: Complete data filled by 1,000 nurses was analyzed. The knowledge of nurses varied across different aspects of IC. A statistically significant association was found between the IC knowledge and the years of experience (P = .003) and the area of working (critical vs semi-critical areas) (P < .001) of nurses. A statistically significant difference was also found in the knowledge of nurses from different hospitals depending upon the accreditation (P < .001) and the teaching status (P = .035), but no significant difference based on the city category of hospital (P > .05). Accreditation showed the strongest association {β = 2.499 (95% CI = 1.67-3.32)} while non-teaching status had a negative impact {β = -1.76 (95% CI = 2.543 to -2.543)} on knowledge using multivariate linear regression analysis., Conclusions: Infection prevention and control is the biggest challenge in any hospital and improving the knowledge and awareness of the nurses on the same is fundamental to its success. A multifaceted approach of continuing education programs, training, and feedback should be undertaken towards improving the awareness and compliance to IC practices., (Copyright © 2022 Association for Professionals in Infection Control and Epidemiology, Inc.

Background: In addition to motor findings, non-motor findings including alterations in visual acuity, decrease in blink reflex, and pupil reactivity cause the impaired quality of life in idiopathic Parkinson's disease (PD) and multiple system atrophy (MSA). Our study aimed to examine possible latency and amplitude changes in pattern visual evoked potentials (pVEP) along with retinal and macular changes in optical coherence tomography (OCT) in PD and MSA groups. We also intended to investigate whether any OCT parameters could be a biomarker for Parkinson's or MSA., Methods: Our study included 50 patients with PD, 15 with MSA, and 50 healthy control subjects. All patients in the study underwent neurological and ophthalmological examination and investigations of OCT to measure the retinal and macular thickness and pVEP to assess visual pathways., Results: When PD, MSA, and control groups were compared, a significant difference was found in all retinal thickness values in average, nasal, and superior retinal nerve fiber thickness (pRNFL), and in all macular thickness values except nasal outer and inferior outer quadrants and in ganglion cell complex (GCC) thicknesses (p < 0.05). Moreover, a significant difference was found in N75, P100, and N145 latencies and N75-P100 amplitude (p < 0.05). The thickness of both pRNFL, inner and outer macular quadrants, was thinner in the MSA group than in PD but GCC thickness was thinner in PD group., Conclusions: The present study compared pVEP and OCT parameters in PD and MSA groups. It was concluded that pVEP and OCT examinations were of importance in that they were easily accessible, affordable, noninvasive biomarkers that might be used in early periods and progression of the disease and in follow-up., (© 2022.

Objective: To compare vestibular migraine (VM) and persistent postural-perceptual dizziness (PPPD) regarding dizziness associated handicap, emotional and somatic disorders, health-related quality of life (QoL) and personality traits., Methods: Thirty patients for each group [VM, PPPD and healthy volunteers (HC)] were studied. Dizziness Handicap Inventory (DHI), Beck depression and anxiety scales, Somatic Symptom Scale-8 (SSS-8), Short Form (36) Health Survey (SF 36) and the Big Five Inventory (BFI) were used., Results: DHI sub-scores were significantly high in both patient groups in comparison with the HC (p < 0.001 for all). Emotional (p = 0.001) and functional (p = 0.022) sub-scores of the PPPD patients were worse. Anxiety and somatic symptom scores of VM (p = 0.026 and p < 0.001 respectively) and PPPD (p < 0.001 for both) and depression scores of the PPPD (p = 0.003) were higher than the HC. Both anxiety (p = 0.009) and somatization (p = 0.005) scores of the PPPD patients were higher than the VM. SF-36subscales were affected in both groups (p < 0.05). Vitality (p = 0.002), mental health (p = 0.045) and social role functioning (p = 0.006) of the PPPD group were worse than the VM. Higher scores for neuroticism (p < 0.001) was present for both groups. Scores for extraversion was low in PPPD patients (p = 0.010) in comparison with the HC., Conclusion: Dizziness associated handicap, anxiety and somatic symptom burden is high in both groups, even higher in PPPD with additional depression. Severe impairment in QoL is present with more severe impairment in emotional aspects in patients with PPPD. Neuroticism is a common personality trait for both groups with additional introversion in PPPD., Competing Interests: Competing interests The authors declare that they have no competing interests., (Copyright © 2022.

Introduction: Narcolepsy type 1 (NT1) is caused by hypocretin deficiency, the pathophysiology of narcolepsy type 2 (NT2) has not been delineated. Except for the hypocretin deficiency and cataplexy, all clinical and laboratory features used in the diagnosis of NT2 are identical to those used for NT1. The aim of this study was to assess the rapid eye movement (REM) sleep-related characteristics in the patients with narcolepsy; the characteristics of REM sleep in polysomnography (PSG) and multiple sleep latency test (MSLT) recordings, the quantification of REM sleep without atonia (RSWA) and atonia index, and the analysis of rapid eye movements (REMs) during REM sleep., Materials and Methods: This study was planned by the Sleep Medicine Study Group of the Turkish Neurology Society, and conducted in 11 centers in eight cities in Turkey. The analysis of RSWA was analyzed by reviewing all REM sleep periods on nocturnal PSG and MSLT recordings per standard criteria. The total duration of the increased muscle tone during REM sleep in the chin and bilateral leg electromyography (EMG) recordings was calculated as RSWA index. The REMs index was also investigated the relation to the RSWA., Results: A total of 274 patients were involved; 147 patients (53.6%) were males and 127 patients (46.4%) were females; the mean age was 29.1 ± 12.0 years. The diagnosis of NT1 was made in 166 patients (60.6%), and 108 patients (39.4%) were diagnosed as having NT2. The mean Epworth sleepiness scale score was significantly higher in patients with NT1 than the patients with NT2 (P = 0.001). The diagnosis of REM sleep behavior disorder (RBD) was made in 19.3% of the patients with NT1 versus in 2.8% of the patients with NT2 (P < 0.001). The percentage of SOREMP in PSG recordings was significantly higher in patients with NT1 (37.1%) than those with NT2 (18.9%, P = 0.001). MSLT showed that the mean sleep latency was shorter in patients with NT1 compared to those with NT2 (P < 0.001). The total duration of REMs on electrooculography recordings was also significantly higher in patients with RSWA in comparison with the patients without RSWA (P = 0.002). Total duration of REMs was significantly and positively correlated with the duration of RSWA on chin-EMG and leg-EMG recordings (P = 0.001). ROC analyses showed an RSWA index of ≥2% for the RSWA on chin-EMG with a sensitivity of 86.7% and a specificity of 71.3% (P < 0.001). The REMs index ≥20% was associated with the presence of RSWA with a sensitivity of 70.0% and a specificity of 57.1% (P = 0.008)., Conclusions: In this nation-wide study, we identified for the first time that the increase in REMs density during REM sleep may be a major correlate of the RSWA. Significant positive correlations were demonstrated between the total duration of REMs on electrooculography recordings and the mean durations of RSWA in both chin and leg EMG recordings. A REMs index of >20% was demonstrated to have a moderate sensitivity and specificity in the diagnosis of RSWA. As observed in chin RSWA index, REMs index also showed a significantly high association with RBD, in comparison to RSWA per standard criteria., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Parkinson's disease (PD) is a progressive condition that affects both the central nervous system and other body parts that are controlled by the nervous system. PD is characterized by brain dopaminergic neurons loss and, at present, there are only symptomatic treatments available to alleviate the effects of the disease. With extensive research, new insights have led to defining PD as a multi-system disorder with immune dysfunction playing a dominant part in the disease pathogenesis as well as its progression. Neuroinflammation in PD leads to neurodegeneration, which is, in turn, regulated by the peripheral adaptive immunity, with CD4+ T cells being a significant player. Patients with PD have diverse CD4+ T cell phenotypes and functional profiles. These phenotypes vary, from being proinflammatory (Th1 and Th17) to anti-inflammatory (Th2 and Tregs). This report focuses on reviewing the expression of CD4+ T cells in PD and its role in the prognosis and treatment of PD.

Aim: During the pandemic of coronavirus disease 2019 (COVID-19), the physicians are using various off-label therapeutics to manage COVID-19. We undertook a cross-sectional survey to study the current variation in therapeutic strategies for managing severe COVID-19 in India., Methods: From January 4 to January 18, 2021, an online cross-sectional survey was conducted among physicians involved in the management of severe COVID-19. The survey had three sections: 1. Antiviral agents, 2. Immunomodulators, and 3. Adjuvant therapies., Results: 1055 respondents (from 24 states and five union territories), of which 64.2% were consultants, 54.3% working in private hospitals, and 39.1% were from critical care medicine completed the survey. Remdesivir (95.2%), antithrombotics (94.2%), corticosteroids (90.3%), vitamins (89.7%) and empirical antibiotics (85.6%) were the commonly used therapeutics. Ivermectin (33%), convalescent plasma (28.6%) and favipiravir (17.6%) were other antiviral agents used. Methylprednisolone (50.2%) and dexamethasone (44.1%) were preferred corticosteroids and at a dose equivalent of 8 mg of dexamethasone phosphate (70.2%). There was significant variation among physicians from different medical specialities in the use of favipiravir, corticosteroids, empirical antibiotics and vitamins., Conclusion: There is a considerable variation in the physicians' choice of therapeutic strategies for the management of severe COVID-19 in India, as compared with the available evidence., (© 2021 John Wiley & Sons Ltd.)

Lesions affecting the body of the optic chiasm typically produce bitemporal hemianopia. The blood supply comes from the anterior communicating artery, anterior cerebral, posterior communicating, posterior cerebral, and basilar arteries. We herein report a young patient admitted to the emergency department with acute confusion, left-sided hemiparesis, hemihypoesthesia, and dysarthria. Bitemporal hemianopia was detected after resolution of confusion. On cranial magnetic resonance imaging (MRI), infarction in the right anterolateral thalamus in the territory of tuberothalamic artery (TA) and in posterior chiasma in the territory of the posterior communicating artery (PCoA) was revealed. Cerebral MR angiography showed luminal irregularity of the PCoA. The patient was presented to draw attention to the rare entity ischemic chiasmal syndrome.

Objectives: The importance of investigating various emotional skills in assessment of suicide risk in alcohol-dependent (AD) individuals has recently become the focus of increasing interest. The objective of this study was to explore the relationships between self-reported components of emotional intelligence and lifetime prevalence of suicide attempts in a clinical sample of AD subjects., Methods: A group of 80 inpatients entering an alcohol treatment program in Warsaw, Poland, was recruited. Baseline information about demographics, psychopathological symptoms, personality, and severity of alcohol problems was obtained. The Schutte Self-Report Emotional Intelligence Test was utilized for assessment of emotional processing. Lifetime history of suicide attempts was obtained from the MINI International Neuropsychiatric Interview., Results: After accounting for affect-related suicide risk factors (severity of depression, anxiety, neuroticism), and also other significant predictors (eg, age, sex, history of childhood abuse), mood regulation/optimism deficits remained a significant correlate of lifetime suicide attempts in AD patients. In the mediation models, mood regulation appeared to fully mediate the relationship between history of suicide attempts and depression, and also neuroticism., Conclusions: The results of this study support the evidence that poor mood regulation might be related to the risk for suicidal behavior in AD individuals. These findings point towards the significance of addressing the issue of emotion-related skills in the therapy of those AD subjects who are at risk for suicide.

Background: Due to the adverse effects produced by the present conventional medicines for anxiety disorders, research for newer drugs is still desirable. From the literature it is evident that NMDA receptors play a key role in animal models of anxiety., Aim: The present study is done to evaluate the antianxiety effect of memantine in swiss albino mice., Materials and Methods: The experimental study was conducted from November 2014 to January 2015. Animals were divided into four groups. Twelve mice were randomly allotted in each group. Animals in the first group received normal saline as a control 10ml/kg, lorazepam 0.5mg/kg was administered to second group, memantine 3mg/kg as a test drug was given to the third group and memantine 3mg/kg + lorazepam 0.5mg/kg was administered to the fourth group. All the drugs were given for 7 consecutive days by intraperitoneal route., Results: Results were analyzed by one-way ANOVA followed by Post-hoc Tukey's test. On the 1(st) day, memantine treated group did not show statistical significant anxiolytic effect in both the behavioural paradigms when compared to control group. On the 8(th) day, the animals showed significant decrease p<0.001 in step down latency period in shock free zone (185.4±3.87 Vs 278.3±5.49), significant increase p<0.001 in step down errors (6.8±0.78 Vs 1.4±0.19) and significant increase p<0.001 in total time spent in shock zone (32.1±2.22 Vs 5.6±0.6). In open field test, on 8(th) day the animals treated with memantine when compared to control group, showed significant increase p<0.001 in number of squares crossed (112.7± 2.69 Vs 83.2±2.96), time spent in central square (11.5±1.26 Vs 3.4±0.65), no. of rearings (32.4±2.61 Vs 17±1.81) and significant decrease p<0.001 in freezing time (15.2±1.12 Vs 20.2±2.29). Memantine showed synergistic antianxiety effect when combined with lorazepam., Conclusion: Memantine showed significant anxiolytic effect in open field and passive avoidance response tests which are commonly used experimental models to assess anxiety states in animals.
