Progerin may also play a role in normal human aging, since its production is activated in typical senescent cells. [18] Unlike other "accelerated aging diseases", such as Werner syndrome, Cockayne syndrome, or xeroderma pigmentosum, progeria may not be directly caused by defective DNA repair. These diseases each cause changes in a few specific ...
Progeroid syndromes (PS) are a group of rare genetic disorders that mimic physiological aging, making affected individuals appear to be older than they are. [1] [2] The term progeroid syndrome does not necessarily imply progeria (Hutchinson–Gilford progeria syndrome), which is a specific type of progeroid syndrome.
An aging-associated disease (commonly termed age-related disease, ARD) is a disease that is most often seen with increasing frequency with increasing senescence. They are essentially complications of senescence, distinguished from the aging process itself because all adult animals age ( with rare exceptions ) but not all adult animals ...
Metabolic diseases come along due to the low demand for physical activity in modern civilization compared to times where humans had to forage in the wild for survival. [10] With the selective shadow now shifted, humans must deal with these new selective pressures. [citation needed]
a spread that moves down the age scale, beginning with older or higher-status people; British psychiatrist Simon Wessely distinguishes between two forms of MPI: [5] Mass anxiety hysteria "consists of episodes of acute anxiety, occurring mainly in schoolchildren. Prior tension is absent and the rapid spread is by visual contact." [9]
The physiological importance for cell senescence has been attributed to prevention of carcinogenesis, and more recently, aging, development, and tissue repair. [9] Senescent cells contribute to the aging phenotype, including frailty syndrome, sarcopenia, and aging-associated diseases. [10]

Stochastic theories of aging are theories suggesting that aging is caused by small changes in the body over time and the body's failure to restore the system and mend the damages to the body. Cells and tissues are injured due to the accumulation of damage over time resulting in the diminished functioning of organs.
