Final answer:
The deposition of amyloid plaques in the brain is the mechanism of disease in Alzheimer's disease.
Step-by-step explanation:
The deposition of amyloid plaques in the brain is the mechanism of disease in Alzheimer's disease.
Amyloid plaques are dense clumps of a protein called beta-amyloid that accumulate between brain cells in Alzheimer's patients. These plaques disrupt normal brain function, leading to cognitive decline and memory loss.
Neurofibrillary tangles, which are tangled bundles of protein fibers within brain cells, also contribute to the progression of the disease. These abnormal protein accumulations cause the affected brain cells to malfunction and eventually die.
