You're probably familiar with the typical symptoms of a concussion: confusion, dilated pupils, or dizziness are all signs of the traumatic brain injury, which generally occurs after a blow to the head. But concussion is actually a very complex condition, and there are many symptoms and signals that you may not have picked up on. From strange visual issues to odd memory problems, getting a concussive brain injury can have unexpected consequences. And just because you might not look like Kat Stratford in 10 Things I Hate About You doesn't mean you don't need to get checked out.
There are a surprising amount of myths surrounding concussions that contribute to our misunderstanding of them. Someone on the receiving end of a concussion may not lose consciousness, nor do you necessarily have to experience a blow to the head to get one; whiplash or being shaken may lead to concussion, according to the Mayo Clinic, even if the head doesn't experience direct force. And you don't actually need to be kept awake after a head injury; if a patient is alert and able to hold a conversation, sleep may actually help them recover, but if the injury is more serious — e.g., they are having trouble walking, or their pupils are dilated — they should seek out a doctor first. Here are other symptoms of a concussion you might not think to look out for.
