What are amyloid plaques and neurofibrillary tangles?

Amyloid plaques and neurofibrillary tangles are indeed considered abnormal protein deposits that are characteristic features of Alzheimer's disease. Amyloid plaques are formed from the accumulation of beta-amyloid protein fragments that clump together in the spaces between neurons. These plaques disrupt cell-to-cell communication and can trigger inflammatory responses, which ultimately contribute to neuronal damage and cell death. Neurofibrillary tangles consist of hyperphosphorylated tau protein, which becomes twisted and forms tangles inside the neurons. This disrupts the intracellular transport systems within neurons, leading to further neuronal degeneration. Their presence is a hallmark of Alzheimer's pathology and is crucial for the diagnosis of the disease, which is why they are integral to understanding the underlying mechanisms of Alzheimer's and its impact on cognitive function.
