When to see a doctor

See a doctor if you or a loved one experiences memory problems or other dementia symptoms. Some treatable medical conditions can cause dementia symptoms, so it's important that a doctor determine the underlying cause.

Alzheimer's disease and several other types of dementia worsen over time. Early diagnosis gives you time to plan for the future while you can participate in making decisions.
