This study aimed to improve our understanding of sleep problems as a comorbidity of hereditary deaf-blindness due to Usher syndrome type 2a. Fifteen patients with Usher syndrome type 2a with a conclusive genetic diagnosis and 15 unaffected controls participated in comprehensive sleep and activity assessments for 2 weeks, using the MotionWatch 8 actigraph and consensus sleep diary. Various sleep parameters including sleep opportunity window, sleep latency, sleep efficiency, and self-reported sleep quality were analysed.

Patients with obsessive-compulsive disorder are presumed to be at higher risk of sleep disorders due to the potential interference that persistent thoughts and compulsions may exert on sleep. Although there are studies on sleep findings in patients with obsessive-compulsive disorder, there are few systematic reviews on the presence of sleep disorders in patients with obsessive-compulsive disorder for adults and children. Preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were followed to perform a comprehensive search of PubMed and Web of Science using the MeSH terms "obsessive-compulsive disorder" and "sleep wake disorders".

Sleep disturbances are associated with intrusive memories, but the neurocognitive mechanisms underpinning this relationship are poorly understood. Here, we show that sleep deprivation disrupts prefrontal inhibition of memory retrieval, and that the overnight restoration of this inhibitory mechanism is associated with time spent in rapid eye movement (REM) sleep. The functional impairments arising from sleep deprivation are linked to a behavioral deficit in the ability to downregulate unwanted memories, and coincide with a deterioration of deliberate patterns of self-generated thought.

This study examines the extent to which functional limitations and poor HRQoL serially explain the link between sleep problems and chronic conditions among single parents in Ghana.
Methods: Data on 627 single mothers and fathers were obtained through a multi-stage stratified sampling technique.
