The Effects of Acute Tryptophan Depletion on Reactive Aggression in Adults with Attention-Deficit/Hyperactivity Disorder (ADHD) and Healthy Controls

Competing Interests: We have read the journal's policy and report that in the past five years FDZ was the recipient of an unrestricted award donated by the American Psychiatric Association (APA), the American Psychiatric Institute for Research and Education (APIRE), and Astra Zeneca (“Young Minds in Psychiatry Award”). He has also received research support from the Federal Ministry of Economics and Technology (Bundesministerium fur Wirtschaft und Technologie, BMWi), the German Society for Social Pediatrics and Adolescent Medicine (Deutsche Gesellschaft fur Sozialpadiatrie und Jugendmedizin, DGSPJ), and from the Paul and Ursula Klein Foundation. He was the recipient of a travel-stipend donated by the GlaxoSmithKline Foundation and an unrestricted educational grant, speaker honoraria and travel support donated by Shire pharmaceuticals. In addition, he has received support from the Raine Foundation for Medical Research (Raine Visiting Professorship). All of the above are unrelated to this specific study. This does not alter our adherence to all the PLoS ONE policies on sharing data and materials. Funding: The present study received in-house funding via the University of Essen, Germany. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
