Alzheimer’s disease is a progressive neurological disorder that affects the brain, primarily causing memory loss and cognitive decline. It is the most common form of dementia, accounting for a significant portion of dementia cases worldwide. Alzheimer’s disease gradually impairs thinking, behavior, and memory, ultimately impacting daily functioning and independence.

The exact cause of Alzheimer’s is not fully understood, but it is believed to be influenced by a combination of genetic, environmental, and lifestyle factors. The disease is characterized by the accumulation of abnormal protein plaques (beta-amyloid) and tangled fibers (tau) in the brain, leading to the degeneration and loss of brain cells.
