Exploring how sleep issues affect emotions in Alzheimer's patients
Sleep Disturbance and Emotion Regulation Brain Dysfunction as Mechanisms of Neuropsychiatric Symptoms in Alzheimer's Dementia
This study is testing how sleep problems affect emotions in people with early Alzheimer's and whether treatments like therapy can help improve their mood and quality of life.

What this trial studies
This study investigates the relationship between sleep disturbances and neuropsychiatric symptoms in individuals at risk for or in the early stages of Alzheimer's Disease. It aims to test a mechanistic model where sleep disruption contributes to emotional distress through impairments in brain function related to emotion regulation. Participants will undergo interventions such as Cognitive Behavioral Therapy for Insomnia and Desensitization Therapy for insomnia to assess their effectiveness in alleviating symptoms. The study seeks to clarify how these factors interact and impact the quality of life for those affected by Alzheimer's.
Who should consider this trial
Good fit: Ideal candidates are males and females aged 50-90 with insomnia and neuropsychiatric symptoms related to Alzheimer's Disease.
Not a fit: Patients without sleep disturbances or those not experiencing neuropsychiatric symptoms may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment strategies for managing neuropsychiatric symptoms in Alzheimer's patients through better sleep management.
How similar studies have performed: Other studies have indicated that addressing sleep disturbances can improve neuropsychiatric symptoms, suggesting a promising avenue for this approach.
