It is time to classify biological aging as a disease

What is considered to be normal and what is considered to be diseased is strongly influenced by historical context (Moody, 2001/2002). Matters once considered to be diseases are no longer classified as such. For example, when black slaves ran away from plantations they were labeled to suffer from drapetomania and medical treatment was used to try to “cure” them (Reznek, 1987). Similarly, masturbation was seen as a disease and treated with treatments such as cutting away the clitoris or cauterizing it (Reznek, 1987). Finally, homosexuality was considered a disease as recently as 1974 (Reznek, 1987). In addition to the social and cultural influence on disease definition, new scientific and medical discoveries lead to the revision of what is a disease and what is not (Butler, 2008). For example, fever was once seen as a disease in its own right but the realization that different underlying causes would lead to the appearance of fever changed its status from disease to symptom (Reznek, 1987). Conversely, several currently recognized diseases, such as osteoporosis, isolated systolic hypertension, and senile Alzheimer’s disease, were in the past ascribed to normal aging (Izaks andWestendorp, 2003; Gems, 2011). Osteoporosis was only officially recognized as a disease in 1994 by the World Health Organization (WHO, 1994).
