neurofibrillary tangle
Quick Summary
Neurofibrillary tangles are pathological accumulations of abnormally formed tau protein found within neurons, primarily in the brain's cerebral cortex and hippocampus. These tangles are a characteristic feature of Alzheimer disease, a progressive neurological disorder that leads to a decline in memory and cognitive abilities. In Alzheimer's, these tangles, along with neuritic plaques, disrupt normal brain function and contribute to the loss of neurons and overall brain mass. While also present in healthy elderly individuals, their abundance is significantly higher in those with Alzheimer's.123

Alzheimer diseaseNeuritic plaques and neurofibrillary tanglesThe presence of neuritic plaques and neurofibrillary tangles in the brain are used to diagnose Alzheimer disease in autopsy. Neuritic plaques—also called senile, dendritic, or amyloid plaques—consist of deteriorating neuronal material surrounding deposits of a sticky protein called amyloid beta (or beta-amyloid). This…
