Abstract

본 발명은 다채널 뇌파 측정 시스템으로부터 측정된 뇌파 신호를 기반으로 특정 주파수 혹은 특정 주파수 대역에서 차원 복잡성(dimensional complexity) 또는 동기화(synchronized)되는 뇌파 신호가 발생하는지를 측정 및 평가하여 치매를 조기에 진단할 수 있는 장치 및 방법을 제공하기 위한 것으로서, 뇌파 신호를 측정하기 위한 복수의 채널을 갖는 전극들을 구비하고 있는 측정부와, 상기 측정부에서 측정된 뇌파 신호를 증폭하는 증폭부와, 상기 증폭된 뇌파 신호를 기반으로 특정 주파수 혹은 특정 주파수 대역에서 차원 복잡성(dimensional complexity) 또는 동기화(synchronized)된 뇌파 신호의 발생 정도를 측정하는 치매 진단부와, 상기 치매 진단부에서 측정된 차원 복잡성 또는 동기화의 발생 정도에 기반하여 치매를 진단하는 치매 판단부를 포함하는데 있다.
