SENILITY
Senility is a disease commonly referred to as dementia. It affects 4 million Americans every year and is a major cause of disability in old age (Bunch, 1997, p. 106). Its prevalence increases with age (Bunch, 1997, p. 106). Dementia is characterized by a permanent memory deficit affecting recent memory in particular and of sufficient severity to interfere with the patient's ability to take part in professional and social activities (Bunch, 1997, p. 106). Although the aging process is associated with a gradual loss of brain cells, dementia is not part of the aging process (Horton and Smart, 1984, p. 320). It also is not synonymous with benign senescent forgetfulness, which is very common in old age and affects recent memory (Bunch, 1997, p. 106). Although the latter is a source of frustration, it does not significantly interfere with the individual activities (or what the individual considers trivial.) Furthermore, patients with benign forgetfulness usually can remember what was forgotten by utilizing a number of subterfuges, such as writing lists or notes to themselves and leaving them in conspicuous places (Horton and Smart, 1984, p. 320). Individuals with benign forgetfulness also are acutely aware of their memory deficit, while those with dementia - except for in the early stages of the disease - have no insight into their memory deficit and often blame others for their problems. In addition to the memory deficit interfering with the patient's daily activities, patients with dementia have evidence of impaired abstract thinking, impaired judgement, or other disturbances of higher cortical functions such as aphasia (the inability to use of comprehend language), apraxia (the inability to execute complex, coordinated movements), or agnosia (the inability to recognize familiar objects) (Bunch, 1997 p.107). Dementia may result from damage to the cerebral cortex, as in Alzheimer's disease, or from damage to the subcortical structures, such as w... Please login to view comments from other users.
