Brief Summary

Obstructive sleep apnoea is the most common sleep disorder in general population, and is often associated with cognitive deficit, mood disorders, hypertension, diabetes mellitus, excessive daytime somnolence, nicturia and an increased cardiovascular and metabolic risk. The gold standard of treatment is Continuous Positive Airway Pressure (CPAP), but the adherence is often poor. The aim of our study is to investigate the effort based-decision making in patients with OSA, pre and post CPAP treatment, as a possible cause of poor adherence.

Study Arms (2)

CPAP Treatment

EXPERIMENTAL

Patients with OSA will undergo cognitive assessment before starting CPAP treatment and after six months of CPAP use.

Device: Continuous Positive Airway Pressure (CPAP) treatment

Control Group

NO INTERVENTION

We will enrol a control group of subjects without sleep disorders and comparable to OSA patients for age and schooling. Control group will undergo cognitive assessment.

Interventions

Treatment of Obstructive sleep apnoea syndrome with CPAP
