Diagnosing dementia, and which type someone has is important. Speak to your doctor who can refer you to a memory clinic or another specialist clinic. Here, you will have tests to determine what is causing your symptoms.

Diagnosing dementia as early as possible is important. It means you will be able to get the right help, treatments and support and plan for the future. You may also want to take part in research studies, and so knowing which type of dementia you have is important too.

If you are worried about symptoms, you should speak to your doctor as soon as possible:

  • They will ask about your symptoms and medical history and may give you a physical check-up.
  • They will do a blood test to rule out other common conditions that might be causing your symtpoms.
  • They may ask you to do some memory and thinking tests.

If your doctor suspects you have dementia, they should refer you to a memory clinic or a specialist for further tests. Other speicalist tests, like brain scans, can help doctors decide which type of dementia someone has.

If you are diagnosed with dementia, you should then be told about the help, support and treatments available. You can choose not to know the results of your tests and diagnosis, and if you choose not to you can nominate someone else to be told.
