Tuesday 5 News told you that Dylan Jeffries' brain aneurysm was caused by a concussion that happened at a previous game, but we don't know that for sure.

We spoke with a neurologist who said when a young person has a brain aneurysm it's usually heredity, but it can also be caused by an excessive blow to the head.

A concussion is when the brain swells because of a hit to head or body causing the brain to rattle around in the skull. No matter what kind of concussion you may suffer, you have to sit out of a practice or a game so you don't get second impact syndrome. That's exactly what it sounds like, when you suffer another concussion too close to the one you had before. Or you could develop chronic issues like constant headaches, sensitivity to sound and light, or difficulty learning. The neurologist told 5 News what he thinks it is, here's what he had to say.

"I find it pretty unlikely that his aneurysm was a result of a previous concussion. It would have had to been a more brain injury in his past. Traumatic brain injuries to the head can predispose someone to the development of an aneurysm, but in younger people we always worry about hereditary concerns," said Tad Seifert, Neurologist. 

If you have a brain aneurysm you usually won't know you have it until it ruptures or leaks, which apparently was the case for Dylan Jeffries.
