Alzheimer'S Brain Changes

Alzheimer's disease, a progressive neurodegenerative disorder, is characterized by distinct changes in the brain. These changes include the accumulation of beta-amyloid plaques outside neurons and the formation of neurofibrillary tangles inside neurons. Beta-amyloid plaques disrupt cell communication, while neurofibrillary tangles impair nutrient transport, ultimately leading to cell death and tissue loss. These pathological changes primarily affect areas of the brain involved in memory, reasoning, and cognition, explaining the characteristic symptoms of Alzheimer's, such as memory loss and cognitive decline. As the disease progresses, these structural changes worsen, impacting broader regions of the brain and exacerbating symptoms. Understanding these brain changes is crucial for developing effective treatments and interventions aimed at slowing or halting the progression of Alzheimer's disease and related dementias.
