They used TPA on me.
I do not think TPA did much either positive or negative, although my wife insisted that TPA made my situation worse.
Right after TPA was applied to me, I had about 10 minutes that I felt things started to come back. However, after that, it felt like falling off the cliff.
I think maybe in my case (it was an artery dissection) what caused the blockage was washed down further.
I have recovered way beyond the original prognosis. The doctors told my wife that I might never stand up or talk again. I am now walking 3 miles a day everyday.
There are still a lot of residuals I am dealing with. But the best help I have got is from my fellow survivors - their tips and insights.
No, I do not think TPA has caused any cognitive deficits in me.
