Topic: Letter of The Law / Mentally Ill Inmates

I am a medically retired felony probation and parole officer from Florida. I am a brain injury survivor, and I have written brain injury, epilepsy, and PTSD poems and prose internationally for the past 16 years. I am a Brain Injury Advocate and maintain a brain injury blog at http://www.noahsarkconsulting.blogspot.com
I am very interested in finding out if there is any rehab for brain injured inmates. Also I am wondering if they are classified as mentally ill?
