CHANGES OF ALPHA WAVES IN ELECTROENCEPHALOGRAMS OF SCHIZOPHRENIA PATIENTS
Main Article Content
Abstract
Objectives: Investigate the energy characteristics, amplitude and frequency of alpha waves from electroencephalography recordings in schizophrenia patients. Methods: Analysis of energy index, frequency and amplitude of alpha waves in 100 schizophrenia patients treated at Department of Psychiatry, Military Hospital 103, which were then compared to those in 100 healthy subjects. Results: The energy and amplitude of alpha waves in the patient group was statistically significantly lower than in the control group in most of the channels recorded in the closed and hyperventilation phases. Meanwhile, the alpha wave frequency did not change in schizophrenia patients compared with the control group. Conclusions: The present study provided new evidence for changes of alpha waves in electroencephalography recordings from patients with schizophrenia.
