ABI, Cough Syncope and Seizures

Michael had multi focal brain hemmorages in 2009. Over the past two years, his cough syncope has gotten a lot worse. One little cough and here is what happens :
He starts to cough, a short sound.
Goes beet red in a split second. I mean bright red, like a newborn.
Face wrinkles up as he looks like a drowning baby.
Shoulders hunch up tight.
May yell or kind of spray spittle.
Eyes roll up and to the right.
Tongue sticks out a bit.
Jaws clamp down.
Michael stops breathing and passes out.
(One time recently, for the first time, I saw his eyes track partly back leftward.)
The unconscious period used to last a second (in 2012 approximately) but now lasts for much longer, up to ten or more seconds.
Comes to utterly disoriented. Takes a while to come fully to consciousness. Feels tired.
Michael Has Fallen and had numerous bruises.
Now he lives on the couch, afraid to go out.
No one has been able to help us. I have only part of several events on video, because the first part happens quickly and I am trying to help Michael, who is passing out in extreme distress.
Please help.
