The potential association between COVID-19 disease and Guillain-Barré syndrome.

The aim is to investigate the rate of GBS in the pre- and postpandemic period and potential differences in probable COVID-19-associated Guillain-Barré syndrome (GBS) cases and nonassociated cases. The medical records of individuals older than 18 years who were hospitalized with acute and rapidly developing progressive extremity weakness between March 2019 and March 2021 were analyzed retrospectively, and the rate of GBS 1 year before the first reported COVID-19 case (March 2020) in Turkey and 1 year later was compared. Neurological symptoms, medical histories, and GBS disability scores, as well as the findings of electrophysiological, blood, and cerebrospinal fluid (CSF) investigations at the time of presentation, were reviewed.

Sarcopenia in patients with multiple sclerosis.

Background: Multiple sclerosis (MS) is an autoimmune neurodegenerative disease of the central nervous system. Sarcopenia, which is characterized by the loss of physical performance and poor outcomes, has recently become the focus of research. However, the relationship between sarcopenia and MS has not yet been investigated.

The yield of electroencephalography in syncope.

Background And Purpose: Syncope is defined as a brief transient loss of consciousness due to cerebral hypoperfusion. Although the diagnosis of syncope is based on a thorough history and examination, electroencaphalography (EEG) is also an important investigational tool in the differential diagnosis in this group of patients. In this study we aimed to identify the diagnostic value of EEG in patients with syncope.
