Concussion vs.
Brain Hemorrhage
It’s important to note that a concussed brain does not bleed.
In fact, a concussed brain can often look perfectly normal on an MRI or CT scan.
But, it’s actually more complicated than that.
This can causebrainischemia(inadequate blood flow in the brain), resulting in more severe and longer-lasting symptoms.
According to the American Association of Neurological Surgeons, a single mild concussion should not cause permanent brain injury.
Resting for longer than 48 hours has been shown to increase recovery times.
Most children fully recover, but may experience permanent disability if another concussion happens soon after the first.
