Disorders: Delirium, Dementia, and Amnesia
Cognitive disorders occur most often in the elderly. Because the average
ages of people in most western societies are increasing, these disorders
assume ever-increasing importance. It is often assumed that delirium and
dementia are inevitable and nearly universal consequences of aging because
they occur most often in older people; however, in some cases the
delirium, dementia, or amnesia can be reversed or held in check. If a
medical condition lies at the root of the problem, that condition may be
curable, and the mental problem will improve along with the physical. If
the problem cannot be treated, the focus shifts to better management of
the problem. For information on each problem, select the appropriate
topic in the outline below.
Amnesias, as the name indicates, are characterized by memory losses
without sufficient cognitive deficits to indicate a diagnosis of delirium
or dementia, and can be subcategorized into those:
