A system and method for detection of a brainstem disorder, such as schizophrenia, by means of brainstem audiometry is disclosed. A subject's (4) responses on the physical properties of sound; 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 (7) 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 electro-physiological brain activity in the subject (4), whereafter mentioned electrophysiological brain activity is stored and imaged, in computer equipment (8) for determination of a brainstem disorder in the subject.

L'invention concerne un système et une méthode permettant de détecter un trouble du tronc cérébral, tel que la schizophrénie, par audiométrie du tronc cérébral. Les réactions d'un patient (4) aux propriétés physiques du son; la fréquence, la durée et l'amplitude sont détectées. Des stimuli sonores sont présentés au patient par l'intermédiaire d'un élément de communication (2), à travers un organe d'audition (3). Des éléments (7) sont fixés sur le patient (4) afin de mesurer l'activité électrophysiologique de son cerveau. En même temps que les stimuli sonores (1) mentionnés précédemment, un signal de déclenchement est envoyé à partir de l'organe de production de stimuli (1), par l'intermédiaire d'un boîtier de déclenchement (5), vers un organe d'enregistrement (6) destiné à enregistrer l'activité électrophysiologique cérébrale du patient (4), ladite activité étant ensuite stockée et imagée dans un équipement informatique (8) afin de détecter un trouble du tronc cérébral chez le patient.
