Reverse the effect

Is it possible to reverse the effects of an AVM in the prefrontal cortex, leftal hemisphere of the brain?

So the blood that broke into your brain, that rushed into the mini veins of it, can be reversed? So you no longer have any side effects, no more brain damage? Not being a specilist, i would still be correct if i say no to that one. yes, over many years, your brain can re-train - i was totally aphasic, i lost the power of speech from scratch - but managed to rebuild it (mostly). Maybe one day, stem cell technology can re-grow tissue - 12 cases are in developement right now in scotland - so who knows........
