Background: The individual experience of fatigue and fatigability in individuals with Multiple Sclerosis (MS) can vary greatly, beyond the high prevalence of fatigue in MS. Although fatigue is known as a common symptom that affects and potentially limits individuals with MS, it has recently been determined that fatigability also causes consequences that limit individuals' daily lives. The purpose of this study was to compare the associations between self-reported levels of fatigue, measured fatigability, and estimates of functional capacity in people with MS and sex- and age-matched healthy individuals.

Article Synopsis
  • A study evaluates patients with antibodies against myelin oligodendrocyte glycoprotein (anti-MOG-IgG), assessing their clinical, radiological, and demographic characteristics in relation to conditions like optic neuritis and myelitis.
  • Among the 104 participants, the majority were women, and the most common diagnoses included NMOSD, isolated optic neuritis, and ADEM, with a notable percentage showing symptoms resembling MS.
  • Findings indicate that older patients (>40 years) experienced more severe disability and poorer responses to treatment, highlighting the significance of anti-MOG-IgG in diagnosing NMOSD in patients without anti-NMO antibodies.

Background/aim: Multiple sclerosis (MS) is an inflammatory demyelinating central nervous system (CNS) disease. Among the paraclinical tests, brain and spinal Magnetic Resonance Imaging (MRI) is primarily involved in the diagnosis process, and cerebrospinal fluid (CSF) analysis is fundamental in diagnosing MS and the differential diagnosis. A positive relationship was demonstrated between oligoclonal band (OCB) positivity, CSF band number and immunoglobulin G(IgG) index.

Background: Symptoms seen in Parkinson's Disease (PD) affect the quality of life (QoL) of individuals.

Objectives: This study aimed to examine the relationship of QoL with tremor severity and upper limb functionality in individuals with PD.

Methods: Parkinson's Disease Quality of Life Questionnaire (PDQ-39) was used to examine the QoL of the participants, electromyography was used to measure the tremor amplitude, Nine-Hole Peg Test (NHPT) was used to evaluate the upper limb functionality and dynamometer was used to evaluate grip and pinch strength.
