Progerin may also play a role in normal human aging, since its production is activated in typical senescent cells. [21] 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 ...
Werner syndrome patients exhibit growth retardation, short stature, premature graying of hair, alopecia (hair loss), wrinkling, prematurely aged faces with beaked noses, skin atrophy (wasting away) with scleroderma-like lesions, lipodystrophy (loss of fat tissues), abnormal fat deposition leading to thin legs and arms, and severe ulcerations around the Achilles tendon and malleoli (around ankles).
DNA repair defects are seen in nearly all of the diseases described as accelerated aging disease, in which various tissues, organs or systems of the human body age prematurely. Because the accelerated aging diseases display different aspects of aging, but never every aspect, they are often called segmental progerias by biogerontologists .
Treatment with cyclodextrin has been shown to delay clinical disease onset, reduced intraneuronal storage and secondary markers of neurodegeneration, and significantly increased lifespan in both the Niemann–Pick type C mice [28] and feline [29] models. This is the second time in the United States that cyclodextrin alone has been administered ...
Other sections include: guidelines updates, international health, and a column written by patients about their experience with the health care system.

Progeroid means "resembling premature aging", a definition that can apply to a broad range of diseases. Familial Alzheimer's disease and familial Parkinson's disease are two well-known accelerated-aging diseases that are more frequent in older individuals. They affect only one tissue and can be classified as unimodal progeroid syndromes.
Chronic diseases in children may have a genetic (hereditary) cause, an environmental (acquired) cause or a combination of both. Early identification and treatment of the disease is key to successful health outcomes. Chronic diseases can affect multiple organ systems and can, therefore, manifest in different ways.
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 ...
