Dear friend, welcome to HCM.
he seems to be on the right track.
what did the MRI
2 mths ago read?
pl. post all reports, so that I can opine better. was a 2D echo done?
recurrent strokes are not uncommon.
if all is well treatment wise, he could benefit by speech therapy
.but let me have his reports first.
take care and keep me posted on your progress.
