I've seen quite a few recommendations for Brainlash by Gail Denton, I did find it helpful.

I found two other books that I even thought were equally helpful information-wise:

Understanding Mild Traumatic Brain Injury (MTBI) Edited by Mary Ann Keatley PhD, CCC and Laura L. Whittemore (A Brain Injury Hope Foundation Publication)

Mild Traumatic Brain Injury: The Guidebook by Mary Lou Acimovic, M.A, CCC-Sp

They are well organized and formatted for people with issues like us.
