sleep-wake cycle disruption
Disturbances in normal circadian rhythms common in elderly patients with psychiatric and neurological conditions, affecting sleep timing and quality.
Full Definition
Sleep-wake cycle disruption encompasses various alterations in circadian rhythms that commonly affect elderly patients, particularly those with dementia, depression, or other psychiatric conditions. This may manifest as advanced sleep phase syndrome (early bedtime and early awakening), delayed sleep phase, fragmented sleep patterns, or complete reversal of day-night cycles. The disruption often results from changes in light exposure, medications, underlying medical conditions, or neurodegenerative processes affecting the brain's circadian control centers. Understanding and addressing these disruptions is crucial for managing behavioral symptoms, improving quality of life, and reducing caregiver burden.
Usage
Usage note: Encompasses broader circadian issues beyond just sleep architecture changes.
