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. [24]

Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.
Aging is natural. Some people age faster than others, often due to lifestyle factors. Here are signs your body may be aging early and how to prevent these changes.
Ageing (or aging in American English) is the process of becoming older until death. The term refers mainly to humans , many other animals , and fungi; whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal .
Senescence (/ s ɪ ˈ n ɛ s ə n s /) or biological aging is the gradual deterioration of functional characteristics in living organisms. Whole organism senescence involves an increase in death rates or a decrease in fecundity with increasing age, at least in the later part of an organism's life cycle.
Biological aging slowed significantly when people followed heart-healthy lifestyle habits, according to new research. ... Strive for normal weight, which is defined as a body mass index between 18 ...
Age-related neuropathologies such as Alzheimer's disease, Parkinson's disease, diabetes, hypertension and arteriosclerosis make it difficult to distinguish the normal patterns of aging. [ 18 ] [ 19 ] One of the important differences between normal aging and pathological aging is the location of neurofibrillary tangles.
