Purpose:

This study will compare four different behavioral treatment programs to determine which is most effective in reducing night-time disturbances in individuals with Alzheimer's disease (AD).


Study summary:

Nocturnal disturbances, such as getting out of bed repeatedly, having hallucinations, talking or singing in bed, and waking up confused are common among patients with AD. Such nocturnal disturbances are associated with increased physical and psychological morbidity in both AD patients and their caregivers and are a major risk factor for patient institutionalization. Nonpharmacologic treatments for these disturbances are needed. This study will assign AD patients to one of four different treatments to determine which is most effective in reducing nocturnal disturbances. This study will last 6 months. Participants will be randomly assigned to a walking program, a light exposure program, a "NITE-AD" program, combining the walking and light exposure programs, or routine AD care with nocturnal disturbance education. Walking program participants will have three 1-hour visits with a therapist over an 8-week period. The therapist and the participant will set an initial daily walking goal and develop a plan for gradually increasing the participants' walking to 30 minutes/day, to be increased at a participant-selected pace. Pedometers will be given to participants to monitor daily activity. The therapist will also discuss exercise safety and will review ways to prevent muscle soreness. Light program participants will also have three 1-hour visits with a therapist over 8 weeks. The therapist will develop a daily, caregiver-supervised light exposure plan requiring participants to sit in front of a light box for 1 hour every day. NITE-AD program participants will have six 1-hour visits with a therapist over 8 weeks; their visits will include setting up both walking and the light exposure routines. Participants assigned to education will receive information about about sleep in aging and dementia, but no assistance setting up walking or light exposure plans. Participants will be assessed at study entry and at Months 2 (post-test) and 6. The sleep patterns of both the patients and the caregivers will be measured. Caregiver reports of patients' night-time behavioral disturbances and readings from an actigraph, a small electronic device worn by participants that records and reports their levels of activity at night, will be used to estimate sleep. The study will also collect data on patient and caregiver mood, stress, and behavior. A follow-up visit will occur 6 months after study completion; at the follow-up visit, the same outcome measures will be collected as at baseline and post-test. Participants will receive 3 biannual phone follow-ups (12, 18, and 24 months) to assess patient residential status and caregiver reports of patient and caregiver sleep.
