Abstract
Purpose
The purpose of this paper was to determine the incidence of depression in our sleep disorders clinics (and it’s relation to patient characteristics) and to determine whether the incidence of depression varies in patients with and without sleep apnea.
Methods
The Beck Depression Inventory (BDI) was administered to evaluate patients for depression. We reviewed records of all new patients between November, 1995 and May, 1996 and determined their BDI scores and polysomnogram (PSC) results. Patients were divided based on their respiratory disturbance index (RDI); a cut off value of 15 was chosen. Patients were re-divided based on the BDI score (13 or greater suggestive of depression). The age, sex, body mass index (BMI), BDI or RDI (as appropriate) and arousal indices were compared.
Results
Sixty-three patients were enrolled; 29% were depressed. BDI scores and PSG data were available in 42 patients. Those with a high RDI had significantly lower BDI scores and higher arousal indices. Those with a high and low BDI scores were not significantly different in any of the parameters evaluated.
Conclusions
Symptoms of depression are commonly seen in a sleep clinic. In patients with symptoms suggestive of SA but with low RDI scores, a diagnosis of depression should be entertained. The presence of depression, however, should not negatively influence a decision to perform PSG.
