Abstract
Sleep and circadian disruptions may be detectable from preclinical stages of dementia, including Alzheimer's disease.
- Alterations in sleep patterns are associated with the progression of dementia.
- Assessing sleep disturbances in dementia patients poses significant challenges.
- Emerging technologies for diagnosing sleep issues require further validation.
- A stepped-care approach is proposed for the accurate diagnosis of sleep disturbances.
- Diagnostic methods range from simple questionnaires to complex biological evaluations of circadian rhythms.
