The Alzheimer's Association leads the fight against Alzheimer's and dementia by funding global research, providing extensive care and support services (like a 24/7 helpline, local chapters, and educational resources), driving early detection and risk reduction, and advocating for policy changes to end the disease and improve lives for those affected. They serve as the largest non-profit funder of Alzheimer's research, aiming to find treatments, preventions, and a cure while supporting millions of patients and caregivers.
