Tipton, KS | Pythagoras (570–495 B.C.), a doctor and mathematician in Greece, classified a lifetime of human into six stages; infancy (age 0–6), adolescence (age 7–21), adulthood (age 22–49), middle age (age 50–62), senescence (age 63–79), and old age (age 80 or older). Of these stages, senescence and old age were regarded as a declining phase of mind and body, and some people who survive to this time, were expected to degenerate in mind to a level of suckling baby and finally become stupid.
Hippocrates (460–370 B.C.), a doctor in Greece, believed that brain injury results in cognitive disorder, and Plato (428–347 B.C.), a philosopher in Greece, mentioned that the principal cause of dementia is old age itself because the mental performance is destined to inevitably degrade. On the contrary, Marcus Tullius Cicero (106–43 B.C.), a philosopher, politician and jurist in Rome, pointed out that ageing does not always cause the decline of mental performance, except in people with weak will. In brief, he indicated that dementia is not an inevitable consequence of ageing.4
