Impact of sleep deprivation on dynamic functional connectivity states.

Sleep deprivation (SD) is an experimental procedure to study the effects of sleep loss on the human brain. Neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), have been pivotal in studying these effects. The present chapter aims to retrace the state of the art regarding the literature that examines the SD effects on the brain through functional connectivity (FC) evaluated in fMRI and EEG settings, separately.

Evaluating the Differential Effects of Dopamine Agonists and Clonazepam on Large Muscle Group Movements in Restless Legs Syndrome.

Study Objectives: This study aimed to investigate the effect of dopamine agonists (DA) and Clonazepam on Large Muscle Group Movements during sleep (LMM), a distinct motor phenomenon, in Restless Legs Syndrome (RLS).

Methods: A retrospective analysis was conducted on 51 drug-free adult patients with RLS, divided into three groups: 33 received a DA (pramipexole or ropinirole), 15 received clonazepam, and 18 received a placebo. Each patient underwent two consecutive nocturnal polysomnographic (PSG) recordings: one baseline and one following treatment administration.

Psychopathology and NREM sleep parasomnias: A systematic review.

Non-rapid eye movement (NREM) sleep parasomnias are abnormal motor and/or emotional behaviors originating from "deep" slow-wave sleep and with a multifactorial origin. The relationship between NREM parasomnias and psychopathology has been a topic of ongoing debate, but a comprehensive and systematic perspective has been lacking. This systematic review, conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA-P) guidelines, aims to fill this gap in the literature.
