Abstract

The aim of this study is to analyze the effectiveness of QEEG-based neurofeedback clinical tests on patients diagnosed with anxiety disorder. Researchers tested six patients with anxiety disorder using 32-channel QEEG(Quantitative electroencephalograpy) and neurofeedback training equipment. The study measured anxiety levels of patients using QEEG and BAI physiological psychology tests. Test results found hyperactive beta waves present in all six patients' temporal lobe. The intensity of the wave of the right hemisphere temporal lobe T4(M=31.07) was the higher than that of the left hemisphere temporal lobe 3(M=29.11). Following Neurofeedback training, the beta wave of the right hemisphere lobe was reduced significantly in all patients. The average anxiety level decreased from 23.57 to 12.14 after the neurofeedback training. In addition, among the two patients who were taking medication, one patient reduced his dosage while the other patient discontinued taking medication. This result implies that the QEEG neurofeedback training technique can be effectively applied to patients with anxiety disorder.

본 논문은 불안장애 환자 6명을 대상으로 32채널 정량화 뇌파(Quantitative Electroencephalograpy)와 뉴로피드백을 이용하여 뇌파를 분석하고 훈련하여 불안장애 환자의 정량화 뇌파 기반 뉴로피드백 훈련의 효과성에 대해 임상연구를 진행하였다. 불안수준을 측정하기 위해 심리생리학적 검사인 정량화 뇌파와 BAI(Beck Anxiety Inventory)를 실시하고, 그 결과를 통해 뉴로피드백 훈련도 진행하였다. 훈련 전 불안장애 환자의 정량화 뇌파 검사를 분석한 결과 6명 환자 모두의 측두엽에서 고베타파가 과잉활성화 된 양상을 볼 수 있었으며, 우뇌 측두엽(T4)의 세기(M=31.07)가 좌뇌 측두엽(T3)의 세기(M=29.11)보다 높았다. 이 결과를 바탕으로 뉴로피드백 프로토콜을 설정하고 훈련을 진행한 결과, 우뇌 측두엽의 베타파가 6명 환자 모두에게서 유의미하게 감소하였다. BAI점수를 분석한 결과 훈련 전의 평균이 23.57, 훈련 후의 평균이 12.14로 뉴로피드백 훈련 후 불안이 감소함을 알 수 있었다. 또한 약물복용을 했던 2명의 환자 중 한 명은 복용량이 줄어들었고 다른 한명은 약물을 중단하게 되었다. 이 결과는 정량화 뇌파 기반 뉴로피드백 훈련이 불안장애를 효과적으로 개선시키는데 사용될 수 있다는 것을 보여준다 하겠다.
