Method and system for diagnosing dementia using brain impedance pattern

The invention discloses a method and a system for diagnosing dementia by using a brain impedance pattern. According to one embodiment of the present invention, the system for diagnosing dementia comprises at least one processor for implementing computer-readable instructions, and the at least one processor may comprise: an electrode pair control unit for controlling a plurality of electrode pairs; a current injection unit that injects current through each of a plurality of electrode pairs formed by any two or more electrodes among a plurality of electrodes attached to a subject to be diagnosed, the any two or more electrodes including a plurality of electrodes attached in relation to the frontal lobe of the subject to be diagnosed; and a dementia diagnosis unit which, on the basis of the result of the current injection, compares the magnitude of the impedance of each of the electrode pairs with a preset impedance value, and diagnoses whether or not the subject is suffering from dementia. 本发明公开一种利用大脑阻抗图案的痴呆症诊断
