The overall goal of this randomized clinical trial is to determine the effectiveness of a stress-busting program (SBP) for caregivers of patients with chronic neurological diseases including stroke, Alzheimer's disease, multiple sclerosis, and Parkinson's disease. Specific research objectives include: 1) Prospectively determine the effects of a SBP compared to a standard support group (SSG) on quality of life and immune response in caregivers of patients with chronic neurological diseases. Subjects will be tested at baseline, at completion of 4 and 8 weeks of SBP or SSG, and at 2- and 4-month follow up sessions. 2) Determine subjects' relaxation response as well as their response to acute laboratory stressors using bioinstrumentation. Muscle tension, electrodermal response, skin temperature, blood volume pulse, and heart rate will be measured. Subjects will be tested at baseline, at completion of 4 and 8 weeks of a SBP or SSG, and at 2- and 4-month follow up sessions. 3) Compare the effectiveness of SBP or SSG for adult children caregivers as compared to spousal caregivers based on quality of life measurements, immune parameters, and relaxation response. The proposed multimodal SBP will focus on a variety of approaches based on cognitive behavioral and relaxation response theories. SBP will consist of a 8-week program with 1�-hour sessions per week. The setting will be an educational support group with topics related to stress, stress and challenges of caregiving, depression, coping strategies, positive thinking, and taking time for oneself. In addition, subjects will be taught simple relaxation strategies that they can practice at home. Outcomes will be measured using psychosocial instruments as well as state-of-the science technology including bioinstrumentation and immune parameters to measure biological responses. Follow up testing will be done 2 and 4 months after the end of the SBP or SSG to determine the long-term effectiveness of the intervention.
