Abstract: A system and method for detection of a brainstem disorder, such as schizophrenia, using brainstem audiometry, is disclosed. A subject's (4) responses on the physical properties of sound, such as frequency, time and amplitude, are being detected. Sound stimuli are being presented, via a communication element (2) through a hearing organ (3) to the subject. Elements (7) are attached to the subject (4) for measurement of the subject's electrophysiological brain activity. Simultaneously as the mentioned sound stimuli (1) are presented to the subject (4) a trig signal is sent out from the organ for generation of stimuli (1), via a trig box (5), further to an organ for registration (6) of the electrophysiological brain activity in the subject (4), whereafter the electrophysiological brain activity is stored and imaged in computer equipment (8) for determination of a brainstem disorder in the subject.
