[Obstructive sleep apnea syndrome in patients attending a psychiatry outpatient service: a case series].

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is a condition associated with multiple negative outcomes. People with mental illness might be at increased risk of having it, given that medication given has adverse effects on weight and there are alterations in sleep associated with them; however, there are few studies in this population.

OBJECTIVE: Describe the patients and the results of polysomnography ordered based on clinical symptoms in a psychiatric outpatient clinic between 2012 and 2014.

METHODS: A case series in which medical records were evaluated.

RESULTS: 58 patients who underwent polysomnography, 89% of them had OSAS, 16% were obese and 19% were been treated with benzodiazepines.

CONCLUSIONS: This is a condition that must be considered during the clinical evaluation of patients with mental illness, since its presence should make clinicians think about drug treatment and follow up.
