Additionally, the study sought to compare these parameters among CSVT subgroups with and without haemorrhage, as well as with and without papilledema.

Comparison of clinical features in patients with vestibular migraine and migraine.

Vestibular migraine (VM) is accepted as the most common cause of spontaneous episodic vertigo. In most patients, vestibular symptoms follow migraine headaches that begin earlier in life. The aim of this multicenter retrospective study was to find out the differences between migraine patients without any vestibular symptoms (MwoV) and VM patients and to delineate the specific clinical features associated with VM.

Methods: Thirty patients for each group [VM, PPPD and healthy volunteers (HC)] were studied. Dizziness Handicap Inventory (DHI), Beck depression and anxiety scales, Somatic Symptom Scale-8 (SSS-8), Short Form (36) Health Survey (SF 36) and the Big Five Inventory (BFI) were used.

Evaluation of the visual system with visual evoked potential and optical coherence tomography in patients with idiopathic Parkinson's disease and with multiple system atrophy.

Background: In addition to motor findings, non-motor findings including alterations in visual acuity, decrease in blink reflex, and pupil reactivity cause the impaired quality of life in idiopathic Parkinson's disease (PD) and multiple system atrophy (MSA). Our study aimed to examine possible latency and amplitude changes in pattern visual evoked potentials (pVEP) along with retinal and macular changes in optical coherence tomography (OCT) in PD and MSA groups. We also intended to investigate whether any OCT parameters could be a biomarker for Parkinson's or MSA.

The REM-sleep-related characteristics of narcolepsy: a nation-wide multicenter study in Turkey, the REMCON study.

Introduction: Narcolepsy type 1 (NT1) is caused by hypocretin deficiency, the pathophysiology of narcolepsy type 2 (NT2) has not been delineated. Except for the hypocretin deficiency and cataplexy, all clinical and laboratory features used in the diagnosis of NT2 are identical to those used for NT1. The aim of this study was to assess the rapid eye movement (REM) sleep-related characteristics in the patients with narcolepsy; the characteristics of REM sleep in polysomnography (PSG) and multiple sleep latency test (MSLT) recordings, the quantification of REM sleep without atonia (RSWA) and atonia index, and the analysis of rapid eye movements (REMs) during REM sleep.

Purpose: To find out clinical features associated with poor response to treatment in vestibular migraine (VM).

Methods: VM patients treated with drugs recommended in migraine prophylaxis were included in this multicenter study. Migraine features including type, age of onset of headache and vertigo attacks, attack frequency, intensity, associated symptoms, triggering factors, presence of interictal dizziness/imbalance, anxiety, depression, history of motion sickness, and family history of migraine were noted.
