An update of the etiology of Alzheimer\'s disease (AD): The current theory of the etiology of AD and the guidelines for most of the wide-ranging treatments activities are built around amyloid and tau protein as causative agents of the disease (Atlante et al., 2020). At present, based on a comprehensive evaluation of existing and contemporary studies, important questions arise regarding the causal role of amyloid and tau protein in the pathogenesis of AD (Morris et al., 2018). Analyzes of the available evidence does not allow obvious conclusion that amyloid, and especially tau protein, plays a key role in the etiology of AD (Morris et al., 2018). Evaluation of new data shows that accumulation of amyloid and altered tau protein is not the main cause of AD and more research is needed (Morris et al., 2018).
