A comprehensive support program: effect on depression in spouse-caregivers of AD patients.
Caregivers of Alzheimer 's disease patients often suffer from depression . Using a longitudinal treatment/control study , we examined the effects of a comprehensive support program on  depression in spouse-caregivers . This psychosocial intervention program treats the primary caregiver and family members over the entire course of the disease through individual and family counseling , the continuous availability of ad hoc counseling , and support group participation . In the first year after intake , the control group became increasingly more depressed , whereas the treatment group remained stable . By the eighth month , treated caregivers were significantly less depressed than those in the control group . These results suggest that enhancing long-term social support can have a significant impact on depression in caregivers
