In addition, the Numbers Needed to Treat (NNT) on the basis of dichotomous treatment response (>50% reduction in HDRS-score immediately after treatment).

Secondary outcome measures are the change in score for measures of sleep (SCOPA-sleep), motor function (UPDRS-III), Quality of Life (WHOQOL-bref, ZBI) and circadian rhythms (actigraphy, cortisol morning curve and melatonin evening curve).
