Rahu and Saturn in the third house of communication and friends. He has Autism because of the maelfic planets in the third house. However his 3rd lord is in the 5th house of education and 5th lord is in the house of gains. I feel he will overcome his challenges in the long run and also have good education. Make sure you continue with his therapy as you are doing now and it will certainly help him in the going forward.
