Alzheimer'S Neuropathology

Alzheimer's disease, a form of dementia, is characterized by distinct neuropathological changes in the brain. These include the accumulation of beta-amyloid plaques outside neurons and neurofibrillary tangles composed of tau protein inside neurons. Beta-amyloid plaques disrupt communication between brain cells, while tau tangles contribute to cell death and tissue loss, particularly in areas crucial for memory and cognitive function, such as the hippocampus and cerebral cortex. These pathological features lead to progressive cognitive decline, memory loss, and eventually, challenges in daily functioning. Understanding these neuropathological changes is crucial for developing effective treatments and interventions to manage Alzheimer's disease and improve quality of life for affected individuals.
