GoldPostal,

Welcome to NeuroTalk.

I have never read that alcohol can make concussion symptoms permanent. It can definitely delay recovery.

What is a HS event. Does HS mean High School ?

If that is so, my biggest concern for you is the long term effect of alcohol on a teens maturing brain regardless of whether you suffer a concussion. There is ample research into the effect getting drunk, especially 'very drunk,' during the teen years has on future brain function.
