What is Alzheimer's Disease
Alzheimer’s Disease is a progressive neurodegenerative disorder that primarily affects memory, thinking, and behavior. It is the most common cause of dementia, especially in older adults. Over time, it leads to severe cognitive decline and loss of independence.
Key Features:
Caused by abnormal build-up of proteins (amyloid plaques and tau tangles) in the brain.
Leads to brain cell damage and death, affecting brain function.
Typically develops after age 65, but early-onset Alzheimer’s can occur earlier.
