BigMtnMom,

Welcome to NeuroTalk. You are wise to be concerned. She should be totally symptom free before she competes again. The risks of Second Impact Syndrome are real. Check out Kevin Pearce. He suffered a second injury before his first healed and it almost killed him. Besides, I doubt she is in top form regarding balance and reaction times. This increases her risk.

Her cognitive struggles show that she had a serious insult to her brain.

Be strong and help her be safe.

My best to you.
