Modifies provisions relating to the Alzheimer's state plan task force

HB 1638 increases the Alzheimer's State Plan Task Force from 21 to 22 members, adding two representatives from voluntary health organizations and one from Missouri veterans' homes. The bill specifies the task force's composition, including members with lived experience (early-stage Alzheimer's patients and family caregivers), healthcare professionals, and representatives from long-term care sectors. The task force must assess state programs, update Missouri's integrated Alzheimer's plan, address health disparities, and coordinate with federal efforts, delivering initial and annual reports to the governor and legislature. It requires the task force to operate until December 31, 2033, with specific term lengths for members appointed after 2026. This bill modifies the task force's structure and reporting obligations to improve coordination and response to Alzheimer's disease in Missouri.
