People normally lose a certain number of brain cells as they age. However, major losses cause progressive and widespread loss of normal brain function. In normal aging, memory loss is usually slow. It may involve forgetting names, phone numbers, or the location of a recently placed item. Intelligence and problem-solving skills are not affected.
True dementia involves loss of intelligence and problem-solving skills.
True dementia cannot be reversed and will become worse over time. Symptoms of dementia often go unrecognized. People sometimes assume that dementia is a normal part of aging . Family members also may not want to face the seriousness of the decline of a loved one. Healthcare providers may misdiagnose the condition.
