Objective. Sleep apnea hypopnea syndrome (SAHS) induces abnormalities in brain function. This study aims to find features that can characterize the impact of SAHS on functional connectivity (FC) during sleep.Approach. Seventy-eight participants (39 patients and 39 age-matched healthy controls) were recruited underwent a whole night polysomnography. The improved weighted phase lag index algorithm was utilized evaluate FC inδ,θ,α,β, andγbands six EEG channels. regional further constructed...
"Early-onset schizophrenia" (EOS) is defined as disease with onset before the age of 18 years. This subset schizophrenia exhibits worse cognitive function and carries a prognosis than adult-onset (AOS). Olfactory impairment has been found in patients schizophrenia-spectrum disorders. However, most research focused on olfactory AOS: EOS not known. The aim this study was to investigate identification ability EOS, its relationship negative symptoms. We compared between two independent samples:...
Abstract Depression is a common mental illness and large number of researchers have been still devoted to exploring effective biomarkers for the identification depression. Few researches conducted on functional connectivity (FC) during sleep in In this paper, novel depression characterization proposed using specific spatial FC features electroencephalography (EEG). Overnight polysomnography recordings were obtained from 26 healthy individuals 25 patients with The weighted phase lag indexes...
Depression, a common mental illness that seriously affects the psychological health of patients, is also thought to be associated with abnormal brain functional connectivity. This study aimed explore differences in sleep-state network topology depressed patients. A total 25 healthy participants and 26 patients underwent overnight 16-channel electroencephalography (EEG) examination. The cortical networks were constructed by using connectivity metrics based on weighted phase lag index (WPLI)...
Sleep state transitions are closely related to insomnia, drowsiness, and sleep maintenance. However, how the cortical network varies during such a transition process remains unclear. Changes in interaction short-term of stage were investigated. In all, 40 healthy young participants underwent overnight polysomnography. The phase transfer entropy six frequency bands was obtained from 16 electroencephalography channels assess strength direction information flow between regions. Differences...
We investigated the nature of interactions between central nervous system (CNS) and cardiorespiratory during sleep.Overnight polysomnography recordings were obtained from 33 healthy individuals. The relative spectral powers five frequency bands, three ECG morphological features respiratory rate six EEG channels, ECG, oronasal airflow, respectively. synchronous feature series interpolated to 1 Hz retain high time-resolution required detect rapid physiological variations. CNS-cardiorespiratory...
Anhedonia, the loss or decline of ability to enjoy pleasure, is an important clinical characteristic schizophrenia. Schizotypal traits refer appearance subclinical symptoms schizophrenia across normal people. Still, few studies have investigated chemosensory anhedonia in patients and schizotypy individuals. Seventy-one (SCZ), 162 individuals (SCT) as selected by Personality Questionnaire (SPQ), 182 healthy controls (HC) participated our study. We used Positive Negative Syndrome Scale (PANSS)...
Depression is a prevalent mental illness with high morbidity and considered the main cause of disability worldwide. Brain activity while sleeping reported to be affected by such illness. To explore change cortical information flow during sleep in depressed patients, delay symbolic phase transfer entropy scalp electroencephalography signals was used measure effective connectivity between regions various frequency bands stages. The patient group control shared similar patterns channels sleep....
Objective To compare the damage degrees between time- and event-based prospective memory (PM) tasks in schizophrenic patients, to explore relationship mental symptoms, individual social function, quality of life medical history. Methods On basis Einstein's McDaniel's dual task paradigm, 56 patients normal subjects were tested using graphical material tasks, including time-based (TBPM) (EBPM). Results The worse than TBPM for correct number ongoing response time [6.50(4.00) vs....
