vSpacer Time course of recovery from depression
Time course of a patient's recovery from depression as reflected by HAMD-17 scores (green square points) assessed at two-day intervals over an observation period of two weeks, plus a final assessment at the time of discharge from hospital ("day63"). The corresponding change over time of the speech parameter "F0-amplitude" is also shown (red circle points) in order to demonstrate the close relationship between the two courses of development (the patient responded to therapy).
