Hello Mom2PCS,

Welcome to the NeuroTalk Support Groups.

I'm sorry about the injury that your son sustained. You may have seen it already but there is a

TBI/Post Concussion Syndrome Forum

At the top of the forum there are what are called "Sticky" threads. There is a lot of excellent information in those, including personal recommendations for vitamins and supplements and other resources. Really worth a read.

A good way to find older threads and posts is to use the
Forum Search Feature
using specific keywords.

I hope your son recovers soon. Rest is very important.

Take care.
