Alzheimer’s disease (AD) is a neurodegenerative disease characterized by progressive cognitive impairment and memory loss. The pathogenesis of AD is complex, depends on many factors, and has not yet been fully studied. Extracellular deposits of amyloid-β (Aβ) peptide in the form of senile plaques, the formation of intracellular neurofibrillary tangles, and massive neuronal loss are considered as the main pathological signs of AD. However, recently there have been many data that indicate other pathways involved in the pathogenesis of AD. This review aims to analyze the existing data on the physiological role of Aβ in the brain under normal conditions and its pathological role in Alzheimer’s disease.

Keywords: amyloid-β; Alzheimer’s disease; cognitive functions; neurodegeneration.
