Looking at the horoscope we see that Lagan is Gemini and Rashi is Leo. He is born under Magha Nakshatra which is a Gandmool Nakshatra. Hence Gandmool puja should be done if not already done. Ketu mahadasha is there till November 2021. Things will improve after he enters Venus mahadasha. Meanwhile you should do consult a good doctor and get the therapy done which will bring lots of improvement.
Make him wear Panna in a locket around his throat and every Saturday do some daan from his hands.
