This invention represents a Cataplexy detecting apparatus, which includes a characteristic capture, and a Cataplexy evaluator. The characteristic capture receives electroencephalogram signals from the subject, and calculates the average value of the received alpha wave, rapid eye movement incubation period, arousal index and others.The Cataplexy evaluator receives the calculated average value of alpha wave, rapid eye movement incubation period, arousal index and others from the characteristic capture, and further using fuzzy calculation to evaluate the Cataplexy index. Acquire the electroencephalogram signals by using a noninvasive technique and to further analyze the frequency variability of the electroencephalogram, evaluating whether Cataplexy may erupt by using sleeping physiological signals characteristics and fuzzy inference, which enables a Cataplexy detecting apparatus to effectively decide whether a Narcolapsy patient has a complication such as Cataplexy.本創作之猝倒症偵測裝置,基本上包括:一特徵擷取器,以及一猝倒症評估器;由特徵擷取器係供接收受測者之腦電圖訊號,且計算出腦電圖訊號中的Alpha波比例平均值、快速動眼期潛伏時間及睡眠覺醒指數等腦電圖特徵;由猝倒症評估器,接收特徵擷取器所計算的Alpha波比例平均值、快速動眼期潛伏時間及睡眠覺醒指數等腦電圖特徵,且進一步利用模糊計算評估猝倒指數。俾獲致一種透過非侵入式擷取腦電圖訊號,且進一步分析腦電圖頻率變異度,利用睡眠生理訊號特徵及模糊推論,評估猝倒症是否發病,有效判斷猝睡症病患是否併發猝倒症的猝倒症偵測裝置。10‧‧‧特徵擷取器20‧‧‧睡眠品質評估器
