Introduction: Cardiology and cardiothoracic surgery are among the specialties that most commonly require neurology inpatient consultations. We aimed to study the neurology referrals by the cardiovascular-specialized hospital included in our tertiary hospital center. Methods: Retrospective study of consecutive patients referred for neurology inpatient consultation between January 1, 2020, and December 31, 2022. We analyzed referrals, patients' characteristics, and the approach taken. A detailed subanalysis was performed for patients diagnosed with acute ischemic stroke (AIS). Results: 143 patients were observed (mean age 67.3 years, 46 [32.2%] females). Most frequent referral reasons were suspected AIS deficits (39.2%), altered mental status (19.6%), suspected seizures (13.3%), and neuroprognostication (11.9%). Mean referral-to-consult time was 2.7 days, and 117 (81.8%) consults were in-person. Additional investigation, treatment changes, and outpatient clinic referral were proposed, respectively, in 79.7%, 60.1%, and 19.6% of patients. Most common diagnoses were AIS (45.5%), hypoxic-ischemic encephalopathy (18.9%), and delirium (7.0%). Regarding patients with AIS (n = 62), most common stroke causes were post-cardiac procedure (44.6%), infective endocarditis (18.5%), aortic dissection (10.8%), acute myocardial infarction (10.8%), and anticoagulant withdrawal in patients with atrial fibrillation (6.2%). Thirty-four AIS patients were diagnosed less than 24 h since last seen well, of which four (6.2%) were treated (three with thrombolysis and one with mechanical thrombectomy). Conclusion: AIS is the most common reason for referral in our cardiovascular hospital. Our results highlight the importance of the availability of a neurologist/neurohospitalist with stroke expertise for consultation of inpatients admitted in a specialized cardiovascular hospital.

Objective: There is little research on the relationship between self‐concept, psychiatric symptoms and quality of life among multiple sclerosis (MS) patients. We assessed the impact of disease perception (expectation and knowledge) on these metrics according to time from diagnosis. Methods: This was an observational, cross‐sectional, multicenter study. Group 1 included patients up to 3 months from MS diagnosis, whereas group 2 included patients with MS diagnosis established for >12 months and <36 months. A 19‐item true/false questionnaire developed by the investigators to assess disease perception, Hospital Anxiety and Depression Scale (HADS), Fatigue Severity Scale and three‐level level version of EQ‐5D questionnaires were used. Results: A total of 90 patients from six centers were included (38 in group 1). A total of 80% had a good disease knowledge, whereas just 48% reported positive expectations. There were no differences in disease knowledge, disease expectations, HADS, Fatigue Severity Scale and EQ‐5D. We found an inverse correlation between disease knowledge and problems in self‐care (P = 0.018) and fatigue (P = 0.032). Patients with the worst expectations about the disease were more anxious (P = 0.012 on HADS and P < 0.001 on EQ‐5D). They also reported more problems in mobility (P = 0.002), self‐care (P = 0.005), usual activities (p = 0.009) and pain (P = 0.001), and a worst health status compared with the past 12 months (P < 0.001) and with the best imaginable status (P < 0.001). Conclusions: Our study showed no association between disease duration and disease perception. Patients with less disease knowledge reported more problems in self‐care and higher fatigue scores. Patients with the worst disease expectations were more anxious and reported a worse health status. More attention should be paid to perceived health status in MS patients. [ABSTRACT FROM AUTHOR]

Background: Previous studies described a parkinsonian personality characterized as rigid, introverted, and cautious; however, little is known about personality traits in de novo Parkinson's disease (PD) patients and their relationships with motor and neuropsychiatric symptoms. Objective: To investigate personality in de novo PD and explore its relationship with PD symptoms. Methods: Using Cloninger's biosocial model, we assessed personality in 193 de novo PD patients. Motor and non-motor symptoms were measured using several validated scales. Cluster analysis was conducted to investigate the interrelationship of personality traits, motor, and non-motor symptoms. Results: PD patients showed low novelty seeking, high harm avoidance, and normal reward dependence and persistence scores. Harm avoidance was positively correlated with the severity of depression, anxiety, and apathy (rs = [0.435, 0.676], p < 0.001) and negatively correlated with quality of life (rs = –0.492, p < 0.001). Novelty seeking, reward dependence, and persistence were negatively correlated with apathy (rs = [–0.274, –0.375], p < 0.001). Classification of patients according to personality and PD symptoms revealed 3 distinct clusters: i) neuropsychiatric phenotype (with high harm avoidance and low novelty seeking, hypodopaminergic neuropsychiatric symptoms and higher impulsivity), ii) motor phenotype (with low novelty seeking and higher motor severity), iii) benign phenotype (with low harm avoidance and high novelty seeking, reward dependence, and persistence traits clustered with lower symptoms severity and low impulsivity). Conclusion: Personality in early PD patients allows us to recognize 3 patients' phenotypes. Identification of such subgroups may help to better understand their natural history. Their longitudinal follow-up will allow confirming whether some personality features might influence disease evolution and treatment. [ABSTRACT FROM AUTHOR]

Cross‐sectional studies suggest a correlation between alterations in dream content reports and executive dysfunction tests in Parkinson's disease (PD), but this has not been assessed in longitudinal studies. Our objective was to assess the predictive value of dream content for progression of cognitive dysfunction in PD. We prospectively addressed all consecutive, non‐demented patients with PD attending an outpatient clinic during a 1‐year period. Dream reports were collected at baseline by means of a dream diary and analysed according to the Hall and Van de Castle system. Patients were assessed at baseline for rapid eye movement sleep behaviour disorder, motor stage, mood disorder and psychosis. The Montreal Cognitive Assessment (MoCA) was applied at baseline and 4 years later. Linear regression analysis was used to the test the relation between each dream index (predictors), demographic and other motor and non‐motor variables (covariates), and change in MoCA scores (dependent variable). In all, 58 patients were assessed at both time points and 23 reported at least one dream (range 1–27, total 148). Aggression, physical activities, and negatively toned content predominated in dream reports. The MoCA scores decreased significantly from baseline to follow‐up. In the multivariate model, negative emotion index was the strongest predictor of cognitive decline. We found a significant positive association between negative emotions in dreams at baseline and subsequent reduction in MoCA scores. These findings suggest that some dream content in patients with PD could be considered a predictor of cognitive decline, independent of other factors known to influence either dream content or cognitive deterioration.

Our objectives were to assess the prevalence of REM sleep behaviour disorder in patients with Essential Tremor, using video‐polysomnography and to compare REM sleep behaviour disorder features in essential tremor with those of patients with alpha‐synucleinopathies. Forty‐nine patients with essential tremor were screened with the REM Sleep Behaviour Disorder Screening Questionnaire. Patients scoring positive and those with spontaneous complaints of REM sleep behaviour disorder (n = 6) underwent video‐polysomnography. The clinical features of essential tremor were compared between patients with and without REM sleep behaviour disorder. Video‐polysomnography data were compared between patients who had essential tremor and Parkinson's disease with REM sleep behaviour disorder and those with idiopathic REM sleep behaviour disorder. Fourteen patients (23.5%) screened positive for REM sleep behaviour disorder, confirmed by video‐polysomnography in five (11.6%). All patients with essential tremor and REM sleep behaviour disorder had rest tremor, compared with 13 (34.2%) in the group with essential tremor but without REM sleep behaviour disorder (p =.009). In video‐polysomnography, patients with essential tremor and REM sleep behaviour disorder were similar to patients with Parkinson's disease with REM sleep behaviour disorder and presented worse sleep dysfunction and lower severity of REM sleep behaviour disorder compared to those with idiopathic REM sleep behaviour disorder. We found a high prevalence of REM sleep behaviour disorder in patients with essential tremor, associated with a predominance of rest tremor. Polysomnography data from patients with essential tremor and REM sleep behaviour disorder were similar to those in patients with Parkinson's disease. This suggests a relation between this subgroup of patients with essential tremor and the alpha‐synucleinopathies. [ABSTRACT FROM AUTHOR]

Spinocerebellar ataxia type 27B (SCA27B) is a recently discovered hereditary disease caused by (GAA)≥250 repeat expansion in the fibroblast growth factor 14 (FGF14) gene, and multiple studies have recognized it as one of the most common causes of autosomal dominant ataxia in the European population. We present the case of a 62-year-old Portuguese patient who developed a slowly progressive gait impairment associated with wide-base ataxic gait, dysarthria, left upper limb dysmetria, and dysdiadochokinesia. This pure cerebellar phenotype had an episodic worsening induced by intense physical activity and alcohol intake. The patient had an older brother with a late-onset cerebellar ataxia of unknown cause. Genetic testing detected a heterozygotic intronic FGF14 repeat expansion with complete penetrance (> 360 repeats), confirming the diagnosis of SCA27B. To our knowledge, we present the first reported case of SCA27B in the Portuguese population.
