As we age, the way in which our brain processes and assimilates information is affected. The speed of the function of the brain declines, but in many cases, the mind remains sharp. In other words, brain and mind are not the same thing. While an elderly person may become overwhelmed or confused, let’s say, in a room full of people talking at once, it doesn’t mean they aren’t still fully functional and able to comprehend what is being said. The normal type of simple memory loss associated with the elderly should not be confused with actual dementia, which is an actual illness.
Dementia, according to the book As Parents Age: A Psychological and Practical Guide, by Joseph Ilardo, Ph.D., L.C.S.W., is defined as gross intellectual impairment resulting in loss of memory and the inability to concentrate. Dementia may be a direct symptom of Alzheimer’s, or can occur as a result of other diseases or conditions.
Dementia can result when the brain suffers one or more mini-strokes that deprive it of oxygen. The brain cells in turn die, and this can result in what is known as vascular dementia. Dementia is not considered part of the normal aging process and is different that regular memory loss. It is estimated that only 10 percent of people over the age of 65 exhibit true dementia.
Dementia can cause restlessness, depression, loss of time and space orientation, changes in personality, delusions or hallucinations. You may find people who suffer with dementia frequently asking the same questions over and over, or repeatedly asking you the date and time.
Dementia affects conscious mental processes, affects memory, interferes with judgment and comprehension, reasoning, solving problems and planning. You may find that the person suffering from dementia can no longer balance their checkbook or do tasks that would ordinarily come easily for them.
If you suspect that a loved one may be exhibiting signs of dementia, please consult their physician for advice on the matter. It is very difficult to watch someone you love suffer with dementia, so be open with their doctor and explore any and all options for dealing with his condition.
