ABSTRACT
Objective To explore the sensitivity and specificity of near-infrared spectroscopy ( NIRS) in the diagnosis of depression. Methods From March 2013 to August 2013,62 patients with de-pression and 70 normal controls were collected from Peking University Sixth Hospital. Optical Tomography System (52 channels) was used to collect the NIRS data during the Verbal Fluency Test (VFT),and the number of words produced during VFT task was recorded. The wave analysis was performed by a professional psychiatrist. Results There was statistical difference in the number of words produced during VFT task be-tween the patients with depression (8.65±0.49)and control group(10.19±0.43) ( t=2.385, P<0.05). Through the wave analysis of NIRS to test patients with depression,the results demonstrated that the sensitivi-ty was 66.1% and the specificity was 91.4%. Conclusion The results of NIRS test display high specificity in the diagnosis of depression,which can be used as an objective index for clinical auxiliary diagnosis.
