How To Treat Severe Bronchial Asthma?

My son 39 has bronchial asthma. feb 28 2013 reacted to 4 days of bad air quality. Passed out, his wife said it took a long time for the ambulance to arrive. His low oxygen enlarged his heart, slowed the emptying. His thickened blood sent 5 clots to the brain. locked in syndrome stroke. he is going off symbicort, his lungs are clear. he still aspirates and his vocal chords are weak. would Asmanex (mometasone) twisthaler be a better choice than Flovent as replacement daily asthma controller? he will have albuterol as a rescue med. He and his wife have asked my opinion. He has had several miracles, but his eyes don t work well. Strabismus and double vision. He thinks clearly, speaks better each week. Thank you.
