ALZHEIMERS DISEASE PATHOGENESIS AND MECHANISM
The trademark highlights of Alzheimer's sickness (AD) are the presence of extracellular amyloid-beta (Aβ) plaques and neurofibrillary tangles in the intracellular condition, neuronal demise and the loss of neurotransmitters, all of which add to a subjective decrease in a dynamic way. Various theories have been progressed to clarify AD. Unusual tau phosphorylation may add to the arrangement of strange neurofibrillary structures. A wide range of structures are powerless to AD, including the reticular arrangement, the cores in the mind stem (e.g., raphe core), thalamus, hypothalamus, locus ceruleus, amygdala, substantia nigra, striatum, and claustrum. Excitotoxicity comes about because of persistent, low-level initiation of N-methyl-D-aspartate (NMDA) receptors.
