“Alzheimer’s Disease” is the term used to describe a dementing disorder marked by certain brain changes, regardless of the age of onset. Alzheimer’s disease is the exception, rather than the rule, in old age. Only 5 to 6 percent of older people are afflicted by alzheimer’s disease or a related dementia–but this means approximately 3 to 4 million Americans have one of these debilitating disorders. Research indicates that 1 percent of the population aged 65-75 has severe dementia, increasing to 7 percent of those aged 75-85 and to 25 percent of those 85 or older. As out population ages and the number of alzheimer’s patients increases, costs of care will rise as well.

Although Alzheimer’s disease is not yet curable or reversible, there are ways to alleviate symptoms and suffering and to assist families.

Problems of memory, particularly recent or short-term memory, are common early in the course of the disease. For example, the individual may, on repeated occasions, forget to turn off the iron or may not recall which of the morning’s medicines were taken. Mild personality changes, such as less spontaneity or a sense of apathy and a tendency to withdraw from social interactions, may occur early in the illness. As the disease progresses, problems in abstract thinking or in intellectual functioning develop. You may notice the individual beginning to have trouble with figures when working on bills, with understanding what is being read, or with organizing the days work. Further disturbances in behavior and appearance may also be seen at this point, such as agitation, irritability, quarrelsomeness, and diminishing ability to dress appropriately.

The average course of the disease from the time it is recognized to death is about 6 to 8 years, but it may range from under 2 years to over 20 years. Those who develop the disorder later in life may die from other illnesses (such as heart disease) before Alzheimer’s disease reaches its final and most serious stage.

The reaction of an individual to the illness and the way he or she copes with it also varies and may depend on such factors as lifelong personality patterns and the nature and severity of the stress in the immediate environment.
