Impact of biological rhythms on perception of illness and cognitive flexibility in bipolar patients in remission.

Our study aims to examine the possible mediating effects of biological rhythms on the relationship between illness perception, cognitive flexibility, and functionality in bipolar patients in remission. A total of 150 patients with bipolar disorder (BD) were enrolled. The sociodemographic data form, Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN), Brief Illness Perception Questionnaire (BIPQ), Cognitive Flexibility Scale (CFS), Young Mania Rating Scale, Montgomery and Asberg Depression Scale, Beck Anxiety Inventory, and Short Functionality Assessment Scale were applied to the patients in the study.

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.

Turkish reliability and validity study of the medical outcomes study (MOS) sleep scale in patients with obstructive sleep apnea.

Background/aim: The purpose of the present study was to evaluate the Turkish reliability and validity of the medical outcomes study (MOS) sleep scale in patients who have obstructive sleep apnea.

Materials And Methods: The data of the study were collected from 120 adult patients with obstructive sleep apnea and from 90 healthy individuals between March 04 and May 31, 2019.

Sleep, sleep spindles, and cognitive functions in drug-naive patients with first-episode psychosis.

Study Objectives: Various lines of clinical findings have suggested abnormalities in macro- or microstructural parameters of sleep in patients with schizophrenia. Meanwhile findings are inconclusive due to some confounding factors, such as the heterogeneity of the disorder, drug regimen, and duration of the illness. There are a few studies in the literature that have been conducted on drug-free patients with first-episode psychosis (FEP).

Is there a relationship between oxygen saturation and MRI-induced anxiety? A prospective study.

Purpose: To prospectively examine the possible relationship between oxygen saturation changes and anxiety during MRI examinations.

Material And Methods: One hundred and fifty randomly-selected patients referred to our department for MRI examination were included. Participants were asked to complete the Spielberger State and Trait Anxiety Inventory (STAI) to monitor subjective evaluation of anxiety.

Relationship between Apnea-Hypopnea Index and Oxygen Desaturation in REM-Sleep Period and Morning Headache in Patients with Obstructive Sleep Apnea Syndrome.

Introduction: In patients with morning headache, REM sleep period decreases though little is known about its physiopathology. We evaluate the polysomnographic records of obstructive sleep apnea syndrome (OSAS) patients with the hypothesis that oxygen desaturations may be a better determinant in patients with morning headache, especially those in REM sleep periods.

Methods: Patient group (group 1) with a total of 361 patients with OSAS and the controls (group 2) with 107 healthy individuals were evaluated.

Assessment of the role of serum ischemia-modified albumin in obstructive sleep apnea in comparison with interleukin-6.

Objectives: There is limited and contradictory information regarding the role of serum ischemia-modified albumin (IMA) in obstructive sleep apnea (OSA). In this study we examine the effects of OSA and obesity on IMA and interleukin-6 (IL-6), and detect whether IMA and IL-6 may be potential biomarkers in OSA.

Methods: Fifty-one males who underwent all night polysomnography test were included into the study.

Mutual information analysis of sleep EEG in detecting psycho-physiological insomnia.

The primary goal of this study is to state the clear changes in functional brain connectivity during all night sleep in psycho-physiological insomnia (PPI). The secondary goal is to investigate the usefulness of Mutual Information (MI) analysis in estimating cortical sleep EEG arousals for detection of PPI. For these purposes, healthy controls and patients were compared to each other with respect to both linear (Pearson correlation coefficient and coherence) and nonlinear quantifiers (MI) in addition to phase locking quantification for six sleep stages (stage.

Clinical and Polysomnographic Features of Kleine-Levin Syndrome: Case Series.

Kleine-Levin Syndrome (KLS) is a rare disorder characterized intermittent hypersomnia, hyperphagia, hypersexuality, abnormal behaviors, and confusion. Patients are asymptomatic between episodes. The aim of this case series study was to determine the clinical features of patients with KLS and to compare the polysomnography (PSG) findings between symptomatic and asymptomatic periods.

Comparison of Polysomnography and Multiple Sleep Latency Test Findings in Subjects with Narcolepsy and İdiopathic Hypersomnia.

Introduction: Both narcolepsy and idiopathic hypersomnia are the main causes of excessive daytime sleepiness. In this study, we aimed to compare polysomnography (PSG) and multiple sleep latency test (MSLT) findings in narcolepsy and idiopathic hypersomnia patients.

Methods: The files of patients with narcolepsy and hypersomnia who were admitted between 1995 and 2009 were reviewed.

[Sleep architecture in schizophrenia patients].

Objective: Sleep disorders are a common and important part of schizophrenia's clinical Picture; however, the number of polysomnography-based studies of schizophrenia is limited and there is a lack of consensus regarding a specific sleep pattern in schizophrenia patients. As such, the aim of the present study was to investigate the sleep architecture in non-medicated schizophrenia patients.

Method: The study included 13 adult male inpatients with schizophrenia, undifferentiated type, (based on DSM-IV-TR criteria) and an age- and sex-matched group of normal controls.

Sleep stage and obstructive apneaic epoch classification using single-lead ECG.

Background: Polysomnography (PSG) is used to define physiological sleep and different physiological sleep stages, to assess sleep quality and diagnose many types of sleep disorders such as obstructive sleep apnea. However, PSG requires not only the connection of various sensors and electrodes to the subject but also spending the night in a bed that is different from the subject's own bed. This study is designed to investigate the feasibility of automatic classification of sleep stages and obstructive apneaic epochs using only the features derived from a single-lead electrocardiography (ECG) signal.

Polysomnography in patients with post-traumatic stress disorder.

Aims: The purpose of the present study was to investigate sleep structure in post-traumatic stress disorder (PTSD) patients with and without any psychiatric comorbidities. The relationship between sleep variables and measurements of clinical symptom severity were also investigated.

Methods: Sleep patterns of 24 non-medicated male PTSD patients and 16 age- and sex-matched normal controls were investigated on polysomnography on two consecutive nights.

Evaluation of periodic leg movements and associated transcranial magnetic stimulation parameters in restless legs syndrome.

Restless legs syndrome (RLS), a sensorimotor disorder characterized by unpleasant sensations commonly localized in the legs, is frequently associated with periodic limb movements (PLMs) during sleep. We investigated the role of transcranial magnetic stimulation (TMS) and cortical silent period (CSP) duration as diagnostic and monitoring tools in 20 patients with primary RLS before and after 1 month of treatment and also studied 15 normal age- and gender-matched subjects. Polysomnographic assessment was undertaken and the PLM index determined in 17 of the 20 patients.
