As your brain injury lawyers
Yanko Popovic Sidhu and its predecessor firms have acted for injured Albertans for more than 40 years, and have represented thousands of clients over that time — including brain injuries arising from collisions, falls and workplace incidents. Brain injury claims are contested more than any other, because the injury is frequently invisible on imaging and its effects are easy for an insurer to attribute to something else.

What these claims involve
Invisible injuryA brain injury frequently does not appear on standard imaging. Insurers use that. Establishing the injury depends on neuropsychological testing, a properly documented symptom history and evidence from people who observed the change.Get in touch
AttributionInsurers commonly attribute cognitive symptoms to pre-existing conditions, stress, sleep, medication or age. Meeting that argument requires a clear before-and-after picture, which is why family and employer evidence matters so much.Get in touch
Cognitive and personality changeThe effects that damage a life most — irritability, loss of initiative, memory and concentration difficulty, changed relationships — are the hardest to document and the easiest to dismiss. They need to be captured deliberately.Get in touch

You do not have to lose consciousness
A traumatic brain injury can occur without any loss of consciousness and without striking your head directly. The absence of either in the ambulance record is not evidence that no injury occurred, though it will certainly be raised.
Normal imaging does not mean no injury
CT and standard MRI frequently appear normal after a mild traumatic brain injury. The diagnosis rests on the mechanism, the clinical history and neuropsychological assessment. Expect the point to be argued and prepare for it.
Keep a record from the beginning
A contemporaneous record of symptoms — kept by the injured person or by a family member — is often the most valuable evidence in the file. Memory for the course of one's own cognitive symptoms is, unsurprisingly, unreliable.
Frequently Asked Questions: Brain Injury Claims in Alberta
My scans were normal but I'm still having symptoms. Do I have a claim?
Possibly, yes. Mild traumatic brain injury commonly does not show on standard imaging. What matters is the mechanism of injury, the documented clinical course, formal neuropsychological assessment and evidence of the change from how you functioned before. A normal scan is a point the insurer will make, not an answer to the claim.
How is a brain injury claim proved?
Through a combination: the mechanism of injury, contemporaneous medical records, neurological and neuropsychological assessment, and evidence from family, friends and employers about the change in function. Where the injury affects earning capacity, vocational and economic evidence is also required. It is a claim built from several sources rather than resting on a single test.
How long do I have to start a claim in Alberta?
In most injury claims the period is two years — but it does not simply run from the date of the incident. It runs from the point at which you knew, or ought reasonably to have known, three things: that you were injured, that the injury was attributable to someone else's conduct, and that it was serious enough to warrant bringing a proceeding. A separate ten-year outer limit runs from when the claim arose, and whichever period expires first governs. Different rules apply to minors and to people under a disability. Because the analysis is fact-specific, the safe course is to ask early rather than assume.
What does it cost to hire a lawyer for this?
We act on a contingency fee basis, which means you pay no legal fees unless compensation is recovered. Disbursements — the out-of-pocket costs of running a file, such as medical records, expert reports and court filing fees — and applicable taxes may still apply. We will explain the arrangement in writing before you retain us.
