It is best to ask my doc, but following a tia, could -very low- dose adderall (or amphetamine based commensurate) help with cognition, if that is indeed a presenting issue post stroke . medical journal articles support this, what are your thoughts?

I would not: recommend this to a patient of mine. As you know, Adderal and other amphetamine-like stimulants can raise blood pressure and heart rate...in general they would not be recommended for people with vascular disease. While one could theoretically see the benefits of such a cognitive stimulant, in my mind the risks would outweigh the benefits. Pursue rehab thinking games, word puzzles, computer tasks..

Yes: Very limited Journal articles to help you with this, but drugs like Adderall, (dextroamphetamine and racemic amphetamine) increase dopamine which increase motivation, which can have a positive impact on cognition.

Rehabilitation: Might be of some use for speech therapy support if a patient does suffer communication issues secondary to a fixed stroke. Ritalin (methylphenidate) is best studied but Adderall would likely work just as well. However, this merely improves focus and concentration, and does not really affect memory or other cognitive domains.
