Schizophrenia and obstructive sleep apnea

Schizophrenics have a higher risk of obstructive sleep apnea than the general population. This increased risk has generally been attributed to obesity and the weight gain caused by antipsychotics.
In addition to obesity, nasal obstruction is also a risk factor for obstructive sleep apnea.
This recent study found reduced nasal cavity size in schizophrenic men:
To investigate, Dr. Moberg's group used acoustic rhinometry to measure nasal volume in 40 men with and 40 without schizophrenia.
They discovered that the schizophrenic patients had smaller posterior nasal volumes in both the left and the right nostrils (p <>

Could reduced nasal cavity size be part of the reason that schizophrenics have higher rates of obstructive sleep apnea??

Or, are people schizophrenic becuase they have smaller posterior nasal volumes?

I love research.

My 17 year old son who is schizophrenic was tested and found to have mild OSA. He was not on antipsychotic medication at the time and he was not at all overweight. I seriously wonder if the sleep apnea causes his schizophrenia even though he only has mild apnea. As a young child and even as a baby he would wake up at night screeming and crying with fright, which now I think might have been be due to apnea.

In you research have you ever found unexplained possibilities of schizophrenic paranoia occuring abruptly or possibly something unexplained, and Do anti psychosis meds truly help. I've been diagnose with severe sleep apnea, My uninterrupted sleep percent was like 15% if even. But 5 months into using cpap I woke up to a dark silhouette feeling like it was choking me to death, I know the cpap can make you feel like your suffocating at times yet the silhouette was more than real i remember taking my mask off before swinging at it. about 2 years after Voices all Day Long 24 hrs 7days a week for about a year and 8 months now. I lost my health insurance and can't afford consultation but I know it's typical for those to be in denial it just seems the voices do things to prove their existence in my world? Should i seek exorcist or psychiatric help?
