Alzheimer's disease is a progressive neurodegenerative disorder that primarily affects the brain's cognitive functions, leading to memory loss, confusion, and changes in behavior. It is the most common cause of dementia, particularly in older adults. The disease is characterized by the accumulation of amyloid plaques and tau tangles in the brain, which disrupt neural communication and lead to cell death. Symptoms often begin with mild memory lapses but gradually worsen, impacting daily activities and eventually requiring full-time care. While the exact cause of Alzheimer's disease is still unknown, a combination of genetic, environmental, and lifestyle factors is believed to contribute to its development. Current treatments focus on managing symptoms, as there is no cure for the disease. Ongoing research aims to better understand the underlying mechanisms of Alzheimer's and develop more effective therapies to slow or halt its progression.
