There are two forms of apraxia, CAS or childhood apraxia of speech, which is usually caused by either genetics or a hypoxic event. Then there's developmental apraxia for which there are several possible causes but basically it's neurological. My son has the latter for which he underwent years of speech therapy. In the beginning he had such poor motor control he drooled.
He's got a small pt job now, he started working at 15 as a web site developer and now builds games for pocket change (mostly indie stuff). He's such a cliche, but frankly he has a gift with all things computer that's amazing. He's a junior in HS and is the teachers aide in a web design class. If he sees the actual teacher once a week it's a lot!
We've started the college search. I'd like him to stay home the first year or so, he wants to flex his wings....there's just not enough Xanax in the world!
