Clinical and demographic characteristics of late-onset multiple sclerosis: LOMS-TR study.

Objectives: Multiple sclerosis (MS), which is known as a young-adult age disease, is called late-onset MS (LOMS) when it occurs at the age of 50 and older.

The objective of our study is to reveal the experiences of the first generic fingolimod active ingredient treatment in different centers across Turkey.

Method: The first generic fingolimod efficacy and safety data of patients followed-up in 29 different clinical multiple sclerosis units in Turkey were analyzed retrospectively.

The Socioeconomic and Psychological Impact of the COVID-19 Pandemic on People with Multiple Sclerosis in Turkey.

Introduction: Various restrictions due to the coronavirus infection have affected working life globally. People with multiple sclerosis (pwMS) have several difficulties in social life, patient follow-up, and receiving treatments. In this study, we aimed to evaluate the experiences of pwMS during the COVID-19 pandemic.

The effect of cognitive performance on self-management behavior of multiple sclerosis patients.

Background: Difficulties of self-management in people with MS (pwMS) is considered as one of the most important factors contributing to low rehabilitation efficacy, more severe long-term complications and increase in healthcare costs. Despite the emergence of research in the last decade documenting causes, types, and course of cognitive difficulties in MS disease subtypes, limited evidence is available in the literature for direct comparison of self-management and cognitive deficits. In this study we aimed to investigate the relationship between cognitive performance and self-management in pwMS.

The efficacy of rituximab in patients with neuromyelitis optica spectrum disorder: A real-world study from Turkey.

Background: Neuromyelitis optica spectrum disorders (NMOSD) are a group of antibody-mediated chronic inflammatory diseases of the central nervous system. Rituximab is a monoclonal antibody that leads to a reduction in disease activity.

Objective: To evaluate the efficacy of rituximab as monotherapy in NMOSD and to determine whether the efficacy varies depending on the presence of antibodies in this cohort.

Effectiveness, Safety, and Health-Related Quality of Life of Chronic Migraine Patients Treated with Onabotulinum Toxin A.

Objective: The present study aims to describe the efficacy and safety of onabotulinum toxin A (BonT-A) with evaluation of treatment satisfaction and impact on quality of life in chronic migraine (CM) patients in real life.

Methods: This study was conducted in CM patients who were treated with BoNT-A with 12 months of follow-up. Data about outcome, adverse events, and patients' pre- and post-treatment status including health-related quality of life data were analyzed.

Background: Vitamin D deficiency is associated with the incidence and prevalence of a variety of neurologic disorders, including multiple sclerosis. However, available studies to date have not provided convincing evidence that vitamin D treatment improves fatigue and life quality in patients with multiple sclerosis.

Aim: To assess the relationship of vitamin D deficiency with health-related quality-of-life issues and fatigue in multiple sclerosis patients.

Flammer syndrome in multiple sclerosis: diagnostics, prediction, and personalization of treatments.

Background: Flammer syndrome (FS) occurs from well-described signs and symptoms. The syndrome itself is not a disease, but it may be a directive marker for advancing therapeutic approaches by predictive and preventive measures as well as for personalization of treatments. The syndrome is related to many diseases, but FS has been rarely studied in multiple sclerosis (MS).

Risk knowledge of people with relapsing-remitting multiple sclerosis - Results of an international survey.

Background: Adequate disease and treatment-related risk knowledge of people with Multiple Sclerosis (pwMS) is a prerequisite for informed choices in medical encounters. Previous work showed that MS risk knowledge is low among pwMS and role preferences are different in Italy and Germany.

Objective: We investigated the level of risk knowledge and role preferences in 8 countries and assessed putative variables associated with risk knowledge.

Longitudinal assessment of gray matter volumes and white matter integrity in patients with medication-overuse headache.

Background Medication-overuse headache is a common clinical entity, but neuroimaging studies investigating volumetric and microstructural alterations of the brain in medication-overuse headache are rare. Therefore, in the current longitidunal study we evaluated gray matter volume and white matter integrity in patients with medication-overuse headache before and after drug withdrawal. Methods A prospective study evaluated 27 patients with medication-overuse headache and 27 age-, sex-, and education-matched healthy adults.

Spontaneous yawning in patients with multiple sclerosis: A polygraphic study.

Background: Patients with multiple sclerosis (MS) suffer from the repetitive yawning and sleep problems. Yawning is observed in MS and other central nervous system disorders and yawning and swallowing may be controlled by the network of the brain stem. Therefore it is important to investigate the MS patients with various clinical and radiological locations in order to understand the role of brainstem on the yawning mechanisms.

Objective/background: Migraine is a common neurological disorder with an uncertain pathogenesis. A pathophysiological link has been proposed between the migraine headache and patent foramen ovale (PFO). However, the data about the association of migraine with the presence of PFO are conflicting.

Reassessment of Lhermitte's sign in multiple sclerosis.

The reliability and diagnostic value of Lhermitte's sign in multiple sclerosis (MS) has not been fully established. The purpose of this study was to determine the clinical, neurophysiological and neuroradiological correlations of Lhermitte's sign in a cohort of MS patients and reassess the relevance of this phenomenon in the clinical history of the disease. A prospective study of 694 patients with MS and 110 age-matched healthy adults was evaluated by a structured questionnaire that included basic demographic data, age of onset, clinical characteristics of the disease, and the inquiry of Lhermitte's sign.
