Objectives: Headache is the most common complaint in cerebral venous sinus thrombosis (CVST) and it may sometimes be the only symptom in these patients. This retrospective and prospective study was an investigation of any differences in terms of clinical risk factors, radiological findings, or prognosis in patients with CVST who presented with isolated headache (IH) and cases with other concomitant findings (non-isolated headache [NIH]).

Methods: A total of 1144 patients from a multicenter study of cerebral venous sinus thrombosis (VENOST study) were enrolled in this research.

Background And Purpose: Matrix metalloproteinases (MMPs), which are synthesized by many cell groups and responsible for the destruction of matrix proteins, and endogen tissue inhibitors of MMPs (TIMPs) have a role in the pathogenesis of Multiple Sclerosis (MS) by affecting the blood-brain barrier. We aimed to investigate the role of MMPs and TIMPs in the immunopathogenesis and in the course of multiple sclerosis (MS).

Methods: We enrolled 25 relapsing remitting MS patients, who had a definite MS diagnosis according to McDonald criteria and 25 healthy subjects similar for age and gender as control group.

Introduction: Cerebral venous and sinus thrombosis (CVST) may lead to cerebral edema and increased intracranial pressure; besides, ischemic or hemorrhagic lesions may develop. Intracerebral hemorrhages occur in approximately one-third of CVST patients. We assessed and compared the findings of the cerebral hemorrhage (CH) group and the CVST group.

Article Synopsis
  • The study focuses on understanding cerebral venous sinus thrombosis (CVST) and its relationship with reproductive health-related risk factors, mainly in women during pregnancy, postpartum, and while using oral contraceptives.
  • Out of 1144 CVST patients, 777 women were analyzed, revealing that the group without reproductive health-related risk factors was older and had higher instances of previous thrombosis and other complications compared to the group with such factors.
  • The findings suggest that age, oral contraceptive use, and the postpartum period increase the risk of CVST, highlighting the importance of early recognition of symptoms, particularly in postpartum women, to improve patient outcomes.

Objective: Epilepsy has long been considered by the society as a dangerous and frightening spiritual possession or even a contagious disease. This results in an unavoidable embarrassment for both the patient and the family leading to social isolation, seclusion, and secretiveness about the diagnosis. The aim of this study was to determine the stigmatizing level of the general Turkish population and to compare these results with the stigmatizing level of the patients' relatives group (PRG).

Objective: Epilepsy is a chronic disease with an increased risk of stigmatization due to psychosocial consequences of the seizures. Intuitively, one may well conclude that stigmatization would lead to depression in patients with epilepsy as well as in other patient groups with increased risk of stigmatization. Indeed, there are a few studies in support of this intuition.

Introduction: Physical inactivity is an important risk factor for stroke and stroke recurrence. There is insufficient knowledge about the physical activity (PA) level in stroke patients who are ambulatory in the subacute phase. Our aim was to compare the PA level between ambulatory stroke patients and a population of the same age and to investigate neuropsychological factors that could affect the PA level in the same stroke group.
