Impact of Alzheimer's disease on sleep in adults with Down syndrome

INTRODUCTION: Down syndrome (DS) is a genetic form of Alzheimer's disease (AD), with a high prevalence of sleep disorders, but data in adults with DS and dementia are lacking. We aim to assess sleep in adults with DS across the AD continuum. METHODS: We studied 78 healthy controls and 229 adult...

Sumario:INTRODUCTION: Down syndrome (DS) is a genetic form of Alzheimer's disease (AD), with a high prevalence of sleep disorders, but data in adults with DS and dementia are lacking. We aim to assess sleep in adults with DS across the AD continuum. METHODS: We studied 78 healthy controls and 229 adults with DS (154 asymptomatic, 25 with prodromal AD, and 75 with AD) with subjective sleep measures and objective nocturnal polysomnography. RESULTS: Adults with DS presented worse sleep quality and higher prevalence of unnoticed obstructive sleep apnea (OSA) than controls. Sleep disruption and OSA severity increased across the AD continuum. Age-related decreases in slow-wave sleep and rapid eye movement sleep were more pronounced in the DS group. Subjective sleep measures did not capture sleep disorders. CONCLUSIONS: In DS, AD is linked to worse sleep disturbances and altered architecture. However, longitudinal studies are needed to clarify directionality and disease progression. Highlights: Down syndrome (DS) is associated with increased slow-wave sleep (SWS) and reduced rapid eye movement (REM) sleep. Obstructive sleep apnea prevalence increases along the Alzheimer's disease continuum in DS. Age-related decreases in SWS and REM sleep are accelerated in DS. Subjective sleep measures do not detect sleep disturbances in adults with DS.
