Joe might developed small strokes (TIAs) as a consequence of a rather benign cardiac arrhythmia (atrial fibrillation). While doctors were trying to determine why his PD symptoms had increased they probably never bothered to consider TIAs as the cause - especially since the increase in symptoms didn't reflect a profound event, such as a full blown stroke would have evidenced. To my knowledge, PD drugs do not cause clot formation. If anyone has any other understanding I would hope that they would share the information with this list. ----- Mary Ann Ryan R.N.
