Soccer...this was his THIRD concussion. Frankly, they didnt treat the
first two seriously enough and I wonder if we would have gotten to number
three.

His symptoms were memory loss, memory problems, headaches.

Yes, he has recovered but having had 3, the chance of future concussions
being more serious is increased. Also, the chance of recovery decreases.

He took no medication for this. His last neuropsych test was back to normal.
He really has no problems or symptoms anymore and his coach, myself, and
his docs would like to keep it that way.

I encourage you talk to to your adult and your coach. They really need to
know.
