Sleep and Rett Syndrome

This study examines the unique social behaviors in individuals with Rett syndrome (RTT), characterized by speech loss, impaired eye contact, gait issues, and sleep disturbances. It aims to identify social patterns in RTT and their relationship with sleep, sleep-disordered breathing (SDB), and daytime sleepiness.

Using factor analysis on 25 social-related items from the RTT Behavioral Questionnaire, we established four social profiles: “interactive motricity,” “mood change,” “anxiety/agitation,” and “gazing.” Results from female subjects with RTT and MECP2 mutations showed varying degrees of social impairments. 

Longer sleep onset latency correlated with increased socio-behavioral issues, particularly in interactive motricity reduction, while higher rapid eye movement sleep was linked to fewer interactive socio-motor behaviors. Interestingly, no significant differences were found regarding SDB or daytime sleepiness presence. 

The study suggests shared disrupted circuits between sensorimotor functioning and sleep-related neuronal pathways, emphasizing the importance of sleep parameters in RTT socio-behavioral outcomes despite no apparent associations with SDB or daytime sleepiness.
