Forgetfulness: It's Not Always What You Think

Picture of vascular dementiaMany older people worry about becoming more forgetful. They think forgetfulness is the first sign of Alzheimer's disease. In the past, memory loss and confusion were considered a normal part of aging. However, scientists now know that most people remain both alert and able as they age, although it may take them longer to remember things.

A lot of people experience memory lapses. Some memory problems are serious, and others are not. People who have serious changes in their memory, personality, and behavior may suffer from a form of brain disease called dementia. Dementia seriously affects a person's ability to carry out daily activities. Alzheimer's disease is one of many types of dementia.

The term dementia describes a group of symptoms that are caused by changes in brain function. Dementia symptoms may include:

  • asking the same questions repeatedly;
  • becoming lost in familiar places;
  • being unable to follow directions;
  • getting disoriented about time, people, and places; and
  • neglecting personal safety, hygiene, and nutrition.
