The present invention discloses a method for detecting human attempting to suicide, which comprises the following steps: (A) utilizing a detecting device capable of detecting instant changes of cerebral blood flow to be arranged in a first detection area, a second detection area, and a third detection area of a head of a subject, in which the first detection area corresponds to a suicidal intent area of a cerebral cortex, the second detection area corresponds to an affirmative responding area of the cerebral cortex, and the third detection area corresponds to a negative responding area of the cerebral cortex (B) detecting active information of the cerebral cortex of the first detection area of the subject within a predetermined time (C) comparing the active information of the cerebral cortex of the first detection area with a normal control group to see whether there is a significant difference (D) inquiring the subject whether she/he has a suicide thought recently (E) detecting via the detecting device whether the second detection area and the third detection area of the subject are significantly active within a predetermined time, and determining whether the answer of the subject is honest according to the answer of "yes" or "no" and (F) according to the result determining whether the subject has the suicide thought or represses an emotion of hidden fury.本發明揭露一種檢測人類企圖自殺的方法,其步驟包括:(A)利用一可檢測腦血流量即時變化之檢測裝置設置於一受測者頭部之一第一待測區域、一第二待測區域及一第三待測區域;其中該第一待測區域對應於大腦皮層之一自殺意圖區,該第二待測區域對應於大腦皮層之一肯定回答區,該第三待測區域對應於大腦皮層之一否定回答區;(B)透過該檢測裝置檢視該受測者一預定時間內該第一待測區域之大腦皮質活躍資訊;(C)將該第一待測區域之大腦皮質活躍資訊與一正常對照組比較是否具有顯著差異;(D)詢問該受測者最近是否有自殺的念頭;(E)透過該檢測裝置檢視該受測者一預定時間內該第二待測區域及該第三待測區域是否有顯著活躍,並根據其回答為「是」或「否」判別該受測者之回答是否誠實;以及(F)根據結果判別該受測者是否具有自殺意圖或壓抑潛藏性暴怒之情緒。
