Premature aging occurs when the typical signs of growing older appear early, per the Cleveland Clinic, so your body may look or feel older than your age in years.
Margaret Casey, a 29-year-old woman with progeria who was then believed to be the oldest survivor of the premature aging disease, died on Sunday, May 26, 1985. Casey, a freelance artist, was admitted to Yale-New Haven Hospital on the night of May 25 with respiratory problems, which caused her death. [82]
mice defective in SIRT7 show phenotypic and molecular signs of accelerated aging such as premature pronounced curvature of the spine, reduced life span, and reduced non-homologous end joining [27] Werner syndrome helicase: Homologous recombination, [28] [29] Non-homologous end joining, [30] Base excision repair, [31] [32] Replication arrest ...
The impact of alcohol on aging is multifaceted. Evidence shows that alcoholism or alcohol abuse can cause both accelerated (or premature ) aging – in which symptoms of aging appear earlier than normal – and exaggerated aging , in which the symptoms appear at the appropriate time but in a more exaggerated form.

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).
Misrepair-accumulation aging theory [88] [89] suggests that the abnormality of tissue structure is the common point between premature aging and normal aging. [90] Premature aging is a result of Mis-construction during development as a consequence of gene mutations, whereas normal aging is a result of accumulation of Misrepairs for the survival ...
