sleep architecture disruption
Alterations in normal sleep stage patterns and transitions commonly seen in elderly patients with psychiatric and neurological conditions.
Full Definition
Sleep architecture disruption refers to changes in the normal structure and organization of sleep cycles, including alterations in REM and non-REM sleep stages, sleep latency, and sleep efficiency. In geriatric psychiatry, this phenomenon is particularly significant as it often accompanies dementia, depression, and other age-related psychiatric conditions. The disruption can manifest as reduced slow-wave sleep, fragmented REM sleep, frequent awakenings, and altered circadian rhythms. Understanding these patterns is essential for developing appropriate sleep interventions and managing behavioral symptoms.
Usage
Usage note: Often occurs alongside but is distinct from specific sleep disorders.
