An
aging-associated disease is a
disease that is most often seen with increasing frequency with increasing
senescence. Essentially, aging-associated diseases are
complications arising from
senescence. Age-associated diseases are to be distinguished from the
aging process itself because all adult animals age, save for a few rare
exceptions, but not all adult animals experience all age-associated diseases. Aging-associated diseases do not refer to age-specific diseases, such as the
childhood diseases chicken pox and
measles. "Aging-associated disease" is used here to mean "diseases of the elderly". Nor should aging-associated diseases be confused with
accelerated aging diseases, all of which are
genetic disorders.
