How Can You Know if Someone With Special Needs Has Dementia?

People with special needs live longer now than in the past. This means they can get dementia just like anyone else. People who have Down syndrome have a very high chance of getting one common type of dementia - Alzheimer's disease. Almost everyone with Down syndrome will get it. And, they often get it at a young age - often in their 40s or 50s. People with seizures that begin in early adulthood also have a higher risk of Alzheimer's disease.

The symptoms of dementia can be different in someone with special needs. It can cause them to forget skills they have learned. And like everyone else who gets dementia, they may be unable to take care of themselves.

If you are taking care of someone with special needs, here are some signs of dementia that you might see.

Signs of Dementia in a Person with Special Needs
  • Less interest in being sociable, talking, or telling you what they think.
  • Less interest in usual activities.
  • Less ability to pay attention.
  • Being sad, fearful, or anxious.
  • Being irritable, aggressive, or not cooperating.
  • Sleep problems.
  • Being noisy.
  • Trouble walking or losing coordination.


Someone with special needs may not understand what 'dementia' is. They may not understand what is happening to them. They may get upset or frustrated. You can help them in several ways. Tell them to see a doctor to find out what kind of dementia they have. Be supportive and patient. Use words they know. Help them to continue doing things they like to do. Keep a normal schedule. Dementia can get worse quickly in people with special needs, so be prepared to add support when needed to keep them safe.
