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??
