Dementia and Alzheimer's disease and the Disability Tax Credit
Dementia and Alzheimer's disease does not qualify or fail to qualify. People do, and only the CRA decides. The CRA does not assess a diagnosis. It assesses how an impairment affects specific activities of daily living, based on what a medical practitioner certifies. Two people with the same condition routinely get different determinations, which is the whole point of a functional test. Anyone who tells you your condition qualifies is guessing.
What this page does instead: it shows which of the CRA's assessment categories a practitioner most often speaks to in this situation, and the detail they will need from you in order to do it accurately.
Categories a practitioner usually speaks to
- Mental functions necessary for everyday life
- Cumulative effect
These are the CRA's own assessment categories. Your practitioner decides which apply to you, and they may reach a different view.
What the CRA is actually asking
Not "how bad is it". The criteria turn on time taken, frequency, assistance needed, and whether that is the case substantially all of the time. In practice that means answering things like:
- What memory, judgment and problem solving look like during an ordinary day
- What supervision or prompting is needed, and for how much of the day
- Which activities can no longer be done safely alone
- How the picture has changed over time
Assessed as you actually live. The CRA assesses you with your usual medication, therapy, aids and devices in place. Describing yourself without them does not answer the question being asked.
The thing most often left out
Descriptions are often written by a family member who has quietly absorbed the tasks. The help being provided is exactly what the CRA needs described, and it disappears from the account precisely because it has become normal.
Part B is your practitioner's
Only a medical practitioner may complete Part B, and the CRA will not process an application where the applicant filled it in themselves. A medical doctor or nurse practitioner may certify all impairments; other practitioners are limited to their own area. What your practitioner needs to know, and what to do if they are hesitant.
Where to start
The self-check walks through these categories and gives you back an organized summary in your own words. It is free, it runs in your browser, and it sends us nothing unless you choose to send it.
Free help is listed here. If you would rather we prepared the documentation, it is a flat CAD 299 (what that includes). We do not determine eligibility, provide medical opinion, or guarantee approval, and nothing on this page is legal, medical, or tax advice.
