    Vascular dementia; The misfolding of proteins is a common component of the proposed pathophysiology of many aging-related diseases. However, there is insufficient evidence to prove this. For example, the tau hypothesis for Alzheimer's proposes that tau protein accumulation results in the breakdown of neuron cytoskeletons, leading to Alzheimer's ...
