A device for evaluation of suicide risk of a person. A measuring unit measures electrodermal activity in fingers of the person to detect depressed persons who are at risk for suicide. The measuring unit is arranged to transmit a sound signal or tone to the person and to provide a signal for analysis of the electrodermal activity from the person. A measuring module measures orientation reactions in the form of blood volume variations of the person, preferably by a phtophletysmographic method peripherally in the fingers and/or centrally in the frontal lobe of the brain through the forehead, and changes in the pulse rate of the test person.
