Poor nutrition, lack of exercise, over-medication, cell damage or disease can all contribute to feeling vulnerable. Yet seniors who resign themselves to feeling bad may delay seeking care for a health problem that is treatable. Only 15 percent of people over age 65 suffer serious mental impairment, with Alzheimer's disease accounting for half of the problems. Dementia, the loss of intellectual function from Alzheimer's disease, stroke or other conditions, can develop at any age. Anyone with symptoms should be evaluated by a physician since some forms of dementia can be cured or helped with the appropriate diagnosis and treatment.
Memory losses Older people sometimes mistake common forgetfulness for dementia.
Reaction times do slow, but loss of intellect is not considered part of the aging process. Taking notes and making lists can help older people improve their working memory. Researchers believe memory is linked to overall health and other factors such as nutrition, and alcohol or drug use. Preserving independence Most people can continue to live independently well into old age, provided they can care for themselves and get around. Only five percent of the elderly are in residential care.
