Background: Fingolimod, natalizumab, and ocrelizumab are commonly used in the second-line treatment of relapsing-remitting multiple sclerosis (RRMS). However, these have only been compared in observational studies, not in controlled trials, with limited and inconclusive results being reported. A comparison of their effect on relapse and disability in a real-world setting is therefore needed.

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.

Article Synopsis
  • The study investigates cardiovascular autonomic dysfunction in patients with recently diagnosed relapsing-remitting multiple sclerosis (MS) compared to healthy controls using 24-hour Holter monitoring for heart rate variability (HRV).
  • It aims to explore the relationships between HRV, the Expanded Disability Status Scale (EDSS), and MRI findings to better understand how MS affects heart functions.
  • Findings indicate that patients with MS have significantly lower HRV compared to healthy individuals, suggesting a potential link between autonomic dysfunction and the disease's severity and type.

Congenital bilateral perisylvian syndrome (CBPS) is a type of cortical developmental abnormality associated with distinctive clinical and imaging features. Clinical spectrum of this syndrome is quite heterogeneous, with different degrees of neurological impairment in affected individuals. High-definition magnetic resonance imaging (MRI) has a great importance in revealing the presence of CBPS, but is limited in elucidating the heterogeneous clinical spectrum.
