Alzheimer’s disease is the most common cause of dementia, a general term for a decline in cognitive ability severe enough to interfere with daily life. It is characterized by a gradual loss of memory, reasoning, and the ability to perform everyday tasks. Over time, individuals with Alzheimer's may struggle with recognizing loved ones, managing their finances, and maintaining independence.
The exact cause of Alzheimer’s disease is still not fully understood, but it involves the buildup of abnormal proteins in the brain, which disrupt normal brain function. This leads to the death of brain cells, causing memory loss, cognitive decline, and behavioral changes. While the disease primarily affects older adults, it is not a normal part of aging.
