[Executive functions in patients with obstructive sleep apnea: exploring the prefrontal model].

Introduction: According to the prefrontal model, individuals with obstructive sleep apnea (OSA) manifest behaviours mimicking dysexecutive syndrome as a result of blood gas abnormalities and sleep fragmentation.

Objective: To compare executive functions in OSA patients with normative values and explore their relationship with blood gas abnormalities and sleep fragmentation.

Patients And Methods: Patients were recruited from the wider community and from a tertiary care hospital.
