Sleep disturbances are commonly reported, although underestimated complaints from people with multiple sclerosis (MS). The aim of the study was to analyze the frequency and type of sleep disturbances in MS patients and to evaluate their relationships with demographics and clinical data. <i>Methods</i>. The study group consisted of 178 patients with relapsing-remitting MS: 130 females and 48 males. Clinical measures (disease duration, disability level in Expanded Disability Status Scale (EDSS), and treatment) were acquired from medical records. The questionnaire was applied, containing questions about sleep disturbances, somatic complaints, perception of fatigue, depression, anxiety, and problems at work and in social/family life. Athens Insomnia Scale (AIS) and Karolinska Sleepiness Scale (KSS) were performed to quantify sleep problems and Hamilton Depression Rating Scale (HDRS) and Addenbrooke’s Cognitive Examination (Mini-ACE) to assess level of depression and cognitive performance. Electroencephalography was recorded to identify electrophysiological indices of sleep. <i>Results</i>. 109 patients (61%) reported sleep disturbances, most frequently insomnia, snoring, and parasomnias. This subgroup had significantly higher scores in AIS (<i>p</i> &lt; 0.0001) and KSS (<i>p</i> = 0.010) and slightly higher EDSS score (<i>p</i> = 0.048) and more often complained of fatigue (71% vs. 53%, <i>p</i> = 0.0148), involuntary limb movement (42% vs. 25, <i>p</i> = 0.0170), and breathing disturbances (10% vs. 0%).

This retrospective study is aimed at investigating the clinical characteristics of autoimmune encephalitis (AE) and long-term prognosis of patients who initially present with seizures as well as risk factors for enduring predisposition to seizures in AE. <i>Methods</i>. From January 1, 2013, to October 31, 2021, a total of 343 AE patients from a single center diagnosed with autoimmune encephalitis (AE) were enrolled in this study, including 198 antibody-positive AE and 145 antibody-negative but probable AE.

In AE, patients with seizures as the first presentation were younger, with a median-onset age of 28 years old. Compared with other types of antibody-positive AE, anti-GABABR AE more frequently began with seizures, while anti-CASPR2, anti-AMPAR, and anti-DPPX encephalitis usually began with symptoms other than seizures.

Although patients can present with progressive pseudobulbar palsy due to neurodegenerative diseases, detection of the precise location of radiological abnormalities can be difficult. ¹⁸F-THK5351 was initially developed as a tau positron emission tomography (PET) tracer.

Nocturnal seizures are usually underestimated and represent a major problem in adult patients with epilepsy.

Observational study of a prospectively acquired sample of adult patients with focal and generalized epilepsy in which perampanel was started from January to October 2021 in a specialized epilepsy unit in a tertiary hospital.

Forty-eight patients were included (mean age 39.8 ± 17.4; 60.4% men), and 38 of them had a 6-month follow-up.
