Trajectories of recovery in depressed Parkinson's disease patients treated with paroxetine or venlafaxine

These findings could guide patient counselling and increase patient compliance by informing about the expected treatment responses. The substantial placebo effect underlines the importance of a sufficiently long study period in future studies.
