Alzheimer’s disease is a progressive neurological disorder that affects memory, thinking, and behavior. It is the most common cause of dementia, a decline in cognitive function that interferes with daily activities. Alzheimer’s disease is characterized by the accumulation of beta-amyloid protein in the brain, which can damage and kill brain cells over time. The exact cause of Alzheimer’s disease is not fully understood, but it is believed to be a combination of genetic, environmental, and lifestyle factors. There is currently no cure for Alzheimer’s disease, but medications and lifestyle changes can help manage symptoms and improve quality of life for individuals with the condition.
