Fact: As people age, it's normal to have occasional memory problems, such as forgetting the name of a person you've recently met. However, Alzheimer's is more than occasional memory loss. It's a disease that causes brain cells to malfunction and ultimately die. When this happens, an individual may forget the name of a longtime friend or what roads to take to return to a home they've lived in for decades.It can be difficult to tell normal memory problems from memory problems that should be a cause for concern. If you or a loved one has memory problems or other problems with thinking and learning that concern you, contact a physician. Sometimes the problems are caused by medication side effects, vitamin deficiencies or other conditions and can be reversed with treatment.
