Comparison of Quantitative Electroencephalography of Schizophrenia Patients With Healthy Controls

Quantitative electroencephalography holds important role in some organic brain diseases. But It’s use is limited in psychiatric disorders like schizophrenia. Previous findings with the schizophrenia were not very consistent with clinical picture of patients. There is definitely altered brain structure in schizophrenia than healthy subjects. The aim of our study is to determine a specific pattern of qEEG for schizophrenia patients which can be useful in early diagnosis and for prognosis.Drug naive newly diagnosed 28 schizophrenia and 32 healthy subjects were gone through 300 seconds eye close supine resting EEG recording over 20 electrodes. Recorded data analyzed by fast Fourier transformation, and then absolute power analyzed by applying unpaired t- test. Schizophrenia Patients showed increased theta and beta activity then healthy subjects.This could be potentially used in early diagnosis and for prognosis of  schizophrenia.
