ADHD is caused by low dopamine, which the stimulants help. However, if someone also suffers from OCD, stimulants can and often do make the OCD symptoms worse. Often what is needed is a SSRI to balance out the two. Some people who have both ADHD and OCD simply cannot be on stimulants. I would definitely take her to see the doctor who prescribed the Vyvanse. If she hasn’t been seen by a mental health professional, you might want to consider it — it would probably help. Good luck, and hope things are better.
