Dementia is a problem in the brain that makes it hard for a person to remember, learn and communicate. After a while, this makes it hard for the person to take care of himself or herself. It is not a specific disease. Memory loss is a common symptom of dementia. However, memory loss by itself does not mean you have dementia. People with dementia have serious problems with two or more brain functions. Common signs of dementia include:

  • Recent memory loss
  • Difficulty performing familiar tasks
  • Problems with language
  • Time and place disorientation
  • Poor judgment
  • Problems with abstract thinking
  • Misplacing things
  • Changes in mood
  • Personality changes
  • Loss of initiative

Many different diseases can cause dementia, including Alzheimer's disease, Parkinson's disease and stroke. Drugs are available to treat some of these diseases. While these drugs cannot cure dementia or repair brain damage, they may improve symptoms or slow down the disease.
