Although the body and mind go through many natural changes as we age, not all changes are normal. There are many misconceptions about what is a normal part of aging. Senility, for example, is not a natural consequence of getting old, though many people believe that it is.
It is important to talk to your physician about any changes you are experiencing. Your doctor can help you differentiate between what is a normal part of aging, and what is not. If necessary, your doctor may refer you to a specialist.
