I ve suffered 4 strokes since March 2014. I saw my neurologist today, and he said the reading of my 6th, yes 6th MRI, shows malformations on the pons area, due to the recurrent strokes. I m getting home care with the visiting nurse, OT, PT & speech therapy. My INR is checked each week. My Coumadin dosage varies, as expected. My doctor wants to keep the level from 2.5-3. Where is the pons part of the brain?
