I have three son's (now 20,18 &16) that all have epilepsy and learning problems.  Our18 year old son has severe adhd, diagnosed at about 6 years also. At one time he was taking seizure,adhd and bi-polar meds. Are the problems that you are having behavior? If he is worse since adding the Tegretol, call you neuro right away and insist that something be done NOW.  It is hard enough parenting these special kids when everything is working together right having these types of problems makes it even harder.  I hope that things work out for you and your son. I have been there and know what you are going through. Good Luck. ANN
