neuritic plaque
Quick Summary
Neuritic plaques, also known as senile or amyloid plaques, are a hallmark of Alzheimer disease. These plaques are deposits of deteriorating neuronal material that surround a core of amyloid beta protein. Amyloid beta is derived from a larger molecule called amyloid precursor protein, which is a normal component of nerve cells. In Alzheimer's patients, this protein clumps together, forming sticky plaques that destroy healthy brain tissue. While these plaques can be found in smaller amounts in healthy elderly individuals, their presence and accumulation are significantly associated with the cognitive decline seen in Alzheimer disease. The exact role of these plaques in the disease's progression is still under investigation, with theories suggesting they may be a cause or a consequence of the disease, potentially linked to infection or inflammation.123
