CSA or ACHS ?

I did a sleep study at home.
I couldnt fall asleep that night because of insomnia.
But i was lying down resting with my eyes closed all night.

My schocking results were:
AHI : 107
ODI : 19
Overall desaturation 4,6%
Central apneas 77%
No Cheyne Stokes breathing.

Im going to a cardiologist next week for a UCG to rule out CHF.
In about two weeks, im going to the hospital for a polysomnogram.

I had an accident 6 years ago.
Traumatic brain injury.
I have ordered a copy of the MRI scans.

Anyone here that suffers from CSA caused by brain damage?
