抑郁症与单纯型精神分裂症鉴别诊断中定量脑电图的应用价值研究

Objective Toexplorethedifferenceofquantitativeelectroencephalography（QEEG）wavefrequenciesof simpleschizophrenia（SS）anddepression.Methods FromOctober2012tomay2013，inWuximentalHealthCenter，30 depression patients（ DP group），30 SS patients（ SS group），30 healthy subjects（ control group） were included in this study. The 3 groups had QEEG testing. The EEG frequency bands were divided intoδ（0.8-4.0 Hz），θ（4.0-7.8 Hz），α（7.8-12.8 Hz），β（13.0-20.0 Hz）. We compared the wave band powers of δ，θ，α，β frequency bands FP1，FP2，F3， F4，F7，F8，T3，T4，T5，T6，C3，C4，P3，P4，O1，O2among3groups.Results Therewassignificantdifferencein the wave band power of δ frequency bands FP1，FP2，F3，F4，F7，F8，T3，C3，C4，P3，P4，O1，O2（P ﹤0.05）， higher in SS group than in control group，those of FP1，FP2，F4，C3，C4，P4，O2 higher in DP group than in control group， those of FP1，FP2，F3，F7 higher in SS group than in DP group（P﹤0.05）. There was significant difference in the wave band powers of θ frequency band F3，F7，F8，P4，O2 among 3 groups（P﹤0.05），those of F3，F7，F8，P4，O2 higher in SS group than in control group，that of F8 higher in DP group than in control group（P﹤0.05）. There was difference in the wave band powers of α frequency band FP1，FP2，F3，F4，F7，F8，T3，T4，T5 among 3 groups（P ﹤0.05），those of FP1， FP2，F3，F4，F7，T3，T4，T5 lower in SS group than in control group，those of FP2，F4，F8 lower in DP group than in con-trol group（P﹤0.05）. There was difference in the wave band powers of β frequency band FP1，FP2，F3，F4，F7，F8，O2 among 3 groups（P﹤0.05），those of FP1，FP2，F3，F4，O2 higher in SS group than in control group，those of FP1，FP2， F3，F4，F7，F8higherinDPgroupthanincontrolgroup（P﹤0.05）.Conclusion ThereisobviousdifferenceinQEEGin-dicators between patients with depression，SS. QEEG is of great value in differential diagnosis of depression and SS.
