Dementia , is a serious loss of global cognitive ability in a previously unimpaired person, beyond what might be expected from normal aging. (Wikipedia)
A research done by Rush University Medical Centre in Chicago throws some light on what cause old people to succumb to dementia.
Placing old people in unfamiliar surroundings of a hospital, together with the sudden loss of their independence like not having to concentrate on daily tasks such as cooking, cleaning or even dressing themselves may be what bring on dementia. Dr Robert Wilson of the hospital suggests that if other studies backed up his findings, the elderly should be encouraged to leave hospital sooner to lessen the effects that bring on dementia.
From a layman’s point of view, if these findings are right, it looks like the root causes of dementia are linked more to emotional and psychological traumas than to physical causes. This seems to point out old people feel a great need for emotional support and emotional reinforcement. It is best to leave them in their ‘comfort zones’ and allow them some independence. Even though they may be old and not in the best of health, they still have their sense of belonging and their sense of self-worth is still intact.
Hope more studies will focus on the emotional causes of this syndrome.
