Son with epilepsy, and diagnosed with ADHD

Patient: My son is 9 years old and has epilepsy. He was diagnosed with adhd when he was 5 and was put on medication. In 3 years he had 3 seizures. I took him off medication 2 years ago thinking this was causing them. He has not had another seizure since. I’m getting a lot of pressure from his school about his behavior, suggesting he needs medication. I don’t want to put him back on it but feel I’m not giving him a chance to get a proper education. Please let me know if adhd medication can trigger a seizure or not. He was on adderall. Thanks for your help.
