Hello ElisabethA,
Welcome to the NeuroTalk Support Groups.
As well as waiting for a reply from momwhocares, I just wanted to suggest you also take a look at the
Traumatic Brain Injury & Post Concussion Syndrome Forum
or perhaps start a new thread with your questions.
Also there is a Forum Search Feature - link posted below.

I ran a search in all forums for Abram Hoffer and one comes up on TBI/PCS forum and also in a few others.
There is also a
Vitamins and Supplements Thread on TBI/PCS as well.
take care.
