Welcome to the NeuroTalk Support Groups.

I doubt very much that an elbow to the head would affect how intelligent you are, but it could give you a headache.

I'm sorry to read about your headaches. Hopefully they settle down soon. I wonder if in a reflex action you wrenched your neck away sharply when you were hit with the elbow? Where in your head are you getting the headaches?

You don't have seizures do you?

Again, if you have serious concerns about your injury, please consult with your medical practitioner.
