There are many misconceptions about dementia. One is that it's a disease. In fact, dementia is a general term describing thinking and memory skills that have deteriorated to the point of experiencing problems with daily activities. Another myth is that dementia is part of normal aging. It isn't; dementia is simply more common as people get older — just like heart disease, stroke, and cancer. Other common myths about dementia include the notions that it always appears as memory loss, it's always genetic, it causes the loss of all memories, and it's never reversible.
