DESCRIPTION
Disorders of Aging and Cognition Dementia – deterioration of one’s memory and related cognitive faculties – is currently the most publicized and feared psychological problem among the elderly It is, however, hardly the only one A variety of psychological disorders are tied closely to later life As with childhood disorders, some of the disorders of old age are caused primarily by pressures that are particularly likely to appear at that time of life, others by unique traumatic experiences, and still others – like dementia – by biological abnormalities Comer, Abnormal Psychology, 6e – Chapter 18TRANSCRIPT
