Learning Disability

My son is a very slow learner (60% IQ). I am a teacher. But for my own case i am helpless. My son had epilepsy seizures for 1.5 years as from 1.5 to 3 years age. After so much medication now no seizures from last 5 years but he has become autistic and slow learner. Presently he takes Valparon 300 Chrono (1-0-1) as per doctors suggestion. We consult to child neurologist. If anybody can suggest some thing it would be a divine help.
