Background And Purpose: Obstructive sleep apnea (OSA) is a common sleep dis-order. Despite many studies, its etiology is not clearly known. Polyamines are ubiquitous positively charged amines found in all or-ga-nisms and one of the polyamines types is spermidine.
View Article and Find Full Text PDFBackground: Numerous cognitive impairments have been documented in patients with epilepsy, particularly in relation to memory and executive functions. However, research on time perception is relatively limited and primarily focuses on temporal lobe epilepsy. The current study seeks to compare time perception performance between patients with focal epilepsy and those with generalized epilepsy.

While HGS has been shown to decline in numerous diseases, it has not been previously examined in patients diagnosed with temporal lobe epilepsy. This study aims to investigate the differences in hand grip strength between individuals with temporal lobe epilepsy and healthy volunteers.
View Article and Find Full Text PDFPurpose: Obstructive Sleep Apnea (OSA) is the most common sleep-related disorder. Interoception is the collection of sensory and cognitive processes that involve receiving and interpreting physiological signals from internal body structures and conveying the perception of inner sensations. In this study, it was hypothesized that the impairment in cognitive functions associated with chronic hypoxemia and the insular effects due to OSA would negatively affect interoceptive functions.
View Article and Find Full Text PDFObjective: We aimed to investigate sleep disorders in patients with epilepsy (PWE) and to investigate the effects of sleep disorders on quality of life.
Methods: In our multicenter study conducted in Turkey, 1358 PWE were evaluated. The demographic and clinical data of the patients were recorded.
Background: Obstructive sleep apnea (OSA) is a frequently observed and remarkably incapacitating disorder worldwide. As a multisystem disorder, OSA has been linked to a plethora of clinical parameters though physical parameters like muscle strength have been scantily studied. Hand grip strength (HGS) is a practical marker of physical function that has been associated with mortality and an array of clinical outcomes as well as physiological parameters like sleep duration.

In this study, it was aimed to investigate the effects of switching off stimulation on time perception in patients with drug-resistant epilepsy who underwent Vagal Nerve Stimulation (VNS). In accordance with the literature, a cognitive battery of tests for motor timing and perceptual timing was utilized. Computerized time perception tests; Paced Motor Timing Test, Duration Discrimination Test, Temporal Reproduction Test, and Time Estimation Test were administered to the patients while VNS was on and off.

Methods: This prospective, observational case-control study included healthy controls and patients with mild, moderate, and severe obstructive sleep apnea syndrome. Vascular parameters, foveal avascular area, and flow areas in macula-centered, 6.
Purpose: Obstructive sleep apnea (OSA) is a disorder characterized by recurrent episodes of obstruction of the upper respiratory tract during sleep often accompanied by oxygen desaturations. Antioxidant defense mechanisms are important to prevent OSA-associated diseases and decrease mortality. We aimed to determine the levels of selenium and vitamins A, C, and E in patients with OSA but without any comorbidities and compare the results with a control group, theorizing that the findings may be helpful to understand the antioxidant mechanisms in the pathogenesis of OSA and associated diseases.

Methods: This study assessed measures of motor threshold, motor evoked potential latency, the cortical silent period, the ipsilateral silent period and the transcallosal conduction time (TCT) in PKD patients. Data were compared between the clinically affected hemisphere (aH) and the fellow hemisphere (fH).

Introduction: Transcranial magnetic stimulation (TMS) is a noninvasive technique for investigating cortical physiologic functions in the brain. In this study, the effects of continuous theta burst stimulation (cTBS) on motor evoked potential (MEP) parameters in patients with idiopathic generalized epilepsy (IGE) were investigated.
Materials And Methods: Fifteen patients with IGE were included.
Introduction: Although it has been shown that immunomodulatory therapies (IMTs) in multiple sclerosis (MS) can modify the course of the disease by reducing the relapse rate and delaying the progression of disability, no study comparing IMTs head-to-head in terms of clinical, radiological, and electrophysiological changes is available. We aimed to investigate the effects of interferon-beta (IFN-B) 1b, IFN-B-1a subcutaneous (sc), IFN-B-1a intramuscular (im), and glatiramer acetate (GA) therapies on clinical, electrophysiological, and radiological findings.
Methods: We studied a cohort of 85 MS patients who were followed up for at least 2 years and had complete charting, including pre-treatment and post-treatment clinical, radiological, and electrophysiological findings.

Objectives: There are some subjective symptoms involving the nasal cavity such as nasal congestion during a migraine attack. In this study, we aimed to evaluate the possible changes occurring in the nasal cavity during headache in patients with migraine.
Materials And Methods: Patients with migraine were studied.
Atherosclerosis, a major cause of ischemic stroke, may be associated with variability of triglyceride (TG) levels. Apolipoprotein A5 (APOA5) genetic polymorphisms are associated with altered TG levels. The objective of this study was to investigate the coding region polymorphisms S19W (rs3135506) and G185C (rs2075291) and the promoter region polymorphism -1131T>C (rs662799) of the APOA5 gene as risk factors for ischemic stroke in Turkish population.
View Article and Find Full Text PDFPurpose: Antiepileptic drugs are generally used to control the cortical hyperexcitable states. But some of them are also effective on the peripheral nervous system, so they may be used in some states like neuropathic pain. Several recent reports suggest the possible effects of antiepileptic drugs on peripheral nerve excitability.

Oxidative stress plays a major role in pathogenesis of atherosclerosis which is responsible for stroke. Glutathione S-transferases (GSTs) detoxify metabolites produced by oxidative stress within the cell and protect the cells against injury. This study aimed to investigate the association of polymorphisms in GSTT1, GSTM1 genes and GST activity with ischemic stroke risk.
