Mr Husband Had A Explicit Stroke Couple Years Ago Since

Mr husband had a explicit stroke couple years ago since then he has a multilevel I'm in strokes,which by the way I was not aware of. Right now the Parkinson's speciliast are treating him for parchinson, which the really not sure if he has it or no . One more month they said on this medication and if it doesn't work he do not have it. Should I be concerned now with the mini strokes he is having. I can't even get in touch with the dr. That ordered the scan. What can I do at ''tis point.should I be concern about the mini stocks or just keep giving him dopamine?
