Towards new indicators of vulnerability to psychotic disorders

New scenarios for the understanding of mental disorders

The decision-making processes of healthy subjects with sub-clinical psychotic episodes are altered in a way that is similar to what happens in subjects with schizophrenia. This is the key result of a study conducted by the Neuroscience and Society Laboratory directed by Raffaella Rumiati of SISSA in association with the Zayed University of Dubai, recently published on Scientific Reports. The research has examined, for the first time, reward mechanisms in healthy people who reported having had psychotic-like episodes, such as auditory hallucinations or lack of motivation, highlighting alterations and identifying possible indicators of vulnerability to psychosis.
