Does long-term stimulant use permanently change brain structure in a harmful way?

No, current evidence doesn't support permanent harmful brain changes from long-term stimulant use at therapeutic doses. Neuroimaging studies following children on stimulant treatment over years have generally found either no structural differences compared with unmedicated peers, or in some cases findings suggesting treatment may normalize some of the structural differences associated with untreated ADHD itself. This is an area of ongoing research rather than a fully closed question, and findings can vary by study design and duration, but the balance of long-term evidence to date doesn't support the fear that stimulant treatment permanently damages the developing brain. If the change is persistent, distressing, or affecting daily functioning, contact your provider through the FasTreat portal rather than changing medication on your own.

Asked my doctor this exact question after reading a scary article. She walked me through the actual research and it was way more reassuring than the headline I'd seen. It's funny how much more comfortable I feel taking it now that I think of it as active treatment instead of some kind of cover-up. A five minute conversation saved me a lot of unnecessary worry, in the end.
