Alzheimer’s disease is the leading cause of dementia, a progressive condition that impairs memory, thinking, and behavior. It is caused by a buildup of amyloid plaques and neurofibrillary tangles in the brain, leading to brain cell death and brain shrinkage. Although there is no cure, treatments and supportive programs can improve symptoms and enhance the quality of life for those affected and their caregivers.
Prevalence of Alzheimer’s Disease
- In the United States, approximately 6.9 million people aged 65 and older live with Alzheimer’s disease.
