How can you determine that you have dementia?

Lately, you may find yourself having difficulties remembering something. It could be the name of a classmate you used to know. Or, you could be struggling to do tasks that are familiar to you, like balancing your chequebook. It's a frustrating feeling, and you may be asking yourself questions like:

Why can't I remember this?

Do I have dementia?

How can I be sure that I have dementia?

Do I need to see a doctor?

If I do have dementia...what happens next?

Getting the answers to these questions can be tricky. Rest assured, the information in this section can help you determine if you are indeed showing signs of dementia, whether you need to see your doctor about your concerns, and what to expect should your doctor recommend that you get tested.

If you are concerned about your memory, the first step you can take is to figure out whether the difficulties with your memory are closer to the signs of dementia, or instead a part of normal aging.

Prepare for your doctor's visit

If you've determined that you are seeing signs of dementia, it's time to make an appointment with your family doctor.

It's important to be open and honest in answering any questions your doctor may have. Only a qualified healthcare provider, like your doctor or a specialist, can make an official diagnosis of dementia. The more information you can give them, the likelier a conclusive diagnosis can be reached.

Understand how diagnosis works

However, you should also know that a diagnosis can take a long time. To ensure that you have an accurate diagnosis, you may be required to take additional tests, or be referred to a memory clinic or a specialist.

Why may that happen? One reason is that there is no one specific test that can diagnose dementia. If your doctor suspects dementia after your initial assessment, but can't make a definitive conclusion, you will most likely undergo a number of physical and cognitive exams. These exams can determine if you are showing signs that line up with the symptoms of dementia.

Once your doctor has a combination of test results, along with your detailed medical history, they should have the evidence needed to give you an official diagnosis.

Know that online self-assessments may not be qualified to diagnose you

You might hear that you don't need to see a doctor to get a diagnosis. Online self-assessments, for example, seem to be an easy way to evaluate your cognitive health. These tests often claim that they can diagnose you effectively, telling you whether you have dementia or not based on the answers you enter.

However, there are many risks involved with taking these online self-assessments, including:

  • Incomplete or inaccurate information that can lead you to make healthcare decisions that can be harmful,
  • The possibility of "false positives" and "false negatives" and
  • Ethical concerns that arise from conflicts of interest from the organization behind an online-self assessment.

Instead of taking an online self-assessment, we recommend that you talk to a qualified healthcare provider, like your doctor, to ensure a safe and accurate diagnosis.
