Impact of diagnosis and treatment of obstructive sleep apnea syndrome (OSAS) with non-invasive ventilation (NIV)

(p = 0.049 – BF1) and temporal posterior for A2 (p = 0.015 – FB 1) and B (p = 0.049 – FB 1 e p = 0.033 – FB 2) possibly as a result of cerebral modifications due to deafness. Deaf subjects seem more sensitive to provoked sleep interruption with remarkable decrease of A1 (p = 0/015) in AA periods. Conclusion: Deaf subjects have more unstable sleep and higher sensitivity to provoked sleep interruption; compromised CAP rhythmicity as well as cortical and spectral modifications in posterior regions, possibly related to their clinical condition.
