Sorry, Jeri, but possible stroke, whether acute (now) or months ago, needs investigating, as there may be ongoing underlying causes, potentially treatable: this is crucial in terms of preventing further episodes. I am only quoting recognised UK stroke management guidelines.
And he could also now be having professional rehab for the episode he "may have had". I agree with Eric. Of course, we don't know how much medical advice he has had to date, but on the face of it, it sounds as if he should be seen much sooner than October.
