Journal ArticleDOI

Stephan Ruhrmann,Frauke Schultze-Lutter,Raimo K. R. Salokangas,Markus Heinimaa,Don H. Linszen,Peter Dingemans,Max Birchwood,Paul Patterson,Georg Juckel,Andreas Heinz,Anthony P. Morrison,Shôn Lewis,Heinrich Graf von Reventlow,Joachim Klosterkötter +13 more
TL;DR: A differential predictive clinical model of transition to first-episode psychosis is developed that identified an increased risk of psychosis with appropriate prognostic accuracy in a sample of help-seeking patients.
Journal ArticleDOI
Dysfunction of ventral striatal reward prediction in schizophrenia.
Georg Juckel,Florian Schlagenhauf,Michael Koslowski,Torsten Wüstenberg,Torsten Wüstenberg,Arno Villringer,Brian Knutson,Jana Wrase,Andreas Heinz +8 more
TL;DR: In unmedicated schizophrenic patients, a high striatal dopamine turnover may increase the "noise" in the reward system, thus interfering with the neuronal processing of reward-predicting cues by phasic dopamine release, which may contribute to negative symptoms as such as anhedonia, apathy, and loss of drive and motivation.
Journal ArticleDOI
Dysfunction of reward processing correlates with alcohol craving in detoxified alcoholics
Jana Wrase,Florian Schlagenhauf,Thorsten Kienast,Torsten Wüstenberg,Felix Bermpohl,Thorsten Kahnt,Anne Beck,Andreas Ströhle,Georg Juckel,Brian Knutson,Andreas Heinz +10 more
TL;DR: The results suggest that mesolimbic activation in alcoholics is biased towards processing of alcohol cues, which might explain why alcoholics find it particularly difficult to focus on conventional reward cues and engage in alternative rewarding activities.
Journal ArticleDOI
Dysfunction of ventral striatal reward prediction in schizophrenic patients treated with typical, not atypical, neuroleptics
Georg Juckel,Georg Juckel,Florian Schlagenhauf,Michael Koslowski,Dimitri Filonov,Torsten Wüstenberg,Torsten Wüstenberg,Arno Villringer,Brian Knutson,Thorsten Kienast,Jürgen Gallinat,Jana Wrase,Andreas Heinz +12 more
TL;DR: Functional magnetic resonance imaging was used to assess the blood oxygen level dependency response in the ventral striatum of medicated schizophrenics and healthy control subjects during reward anticipation to reflect the improved efficacy of these drugs in treating negative symptoms.
Journal ArticleDOI
Reward anticipation and outcomes in adult males with attention-deficit/hyperactivity disorder
Andreas Ströhle,Meline Stoy,Jana Wrase,Steffi Schwarzer,Florian Schlagenhauf,Michael Huss,Jakob Hein,Anke Nedderhut,Britta Neumann,Andreas Gregor,Georg Juckel,Brian Knutson,Ulrike Lehmkuhl,Michael Bauer,Andreas Heinz +14 more
TL;DR: It is suggested that male adults with ADHD show neural signs of abnormal reward processing and future studies will have to investigate whether these dysfunctional patterns might be normalized by treatment.
