What Is This Study About?
This study will evaluate whether treatment for insomnia can reduce neuropsychiatric symptoms, such as anxiety, depression, agitation, irritation, and apathy, in adults with or at risk of developing Alzheimer's disease. Participants will be randomly assigned to either cognitive behavioral therapy or desensitization therapy for insomnia for six weeks. All participants will keep a sleep diary and wear a wrist device to track their sleep. Researchers will measure neuropsychiatric symptoms and severity of insomnia at study start, weekly during treatment, and six months after treatment. In addition, the researchers will obtain an MRI brain scan at the start of the study and after six weeks to evaluate emotional responses.
