Virtual Lifestyle Modification/Brain Health Group for Patients with early AD on DMT and their Support Partners

This novel Brain Health program is a virtual clinical group for patients with early AD receiving DMT (eg, lecanemab) and their chosen support partners. Duration is 6 months, with sessions held every other week for 60-90 minutes, led by neuropsychologists. Each month begins with a didactic session, covering psychoeducation on key brain health topics specific to early AD (i.e., cognitive and social engagement, exercise, diet, mindfulness, sleep). Subsequent sessions each month will focus on dyadic check-ins to develop SMART goals related to lifestyle modification. Questionnaire data will be collected for patients and partners at baseline, 3-month midpoint, and treatment completion, and at 6-month and 12-month follow-up post-treatment to assess maintenance of gains. Measures assess various topics including knowledge of dementia risks and lifestyle recommendations, motivation, self-efficacy, and wellbeing. The primary aim is to provide a supportive clinical service focused on lifestyle modification to optimize brain health, agency, and emotional well-being for patients receiving DMT for AD and support partners. Secondary aims, grounded in theories of Self-Determination, motivation, and behavior change, include evaluating mechanisms of change and partner support styles to enhance understanding of effective interpersonal support approaches and barriers/facilitators to lifestyle modification for brain health. Impact will be maximized by implementing a 6-month group with patients and partners to support lasting behavior change, potentially enhance DMT outcomes, and target multiple levels of prevention.
