Evaluation of relationships between presence of adhesio interthalamica and cannabis use in first-episode psychosis: a magnetic resonance imaging investigation

ABSTRACT Recent studies suggested that cannabis use influences on the emergence of psychosis by disrupting neurodevelopmental processes that occur during adolescence and early adulthood and which are reflected on brain anatomical changes detectable with MRI. However, no MRI studies have investigated whether intrauterine neurodevelopmental abnormalities also interact with later cannabis use to influence on psychosis risk. We investigated differences between first-episode psychosis (FEP) patients with history of cannabis use (FEPC+, n=28), FEP subjects without cannabis use (FEPC-, n=78) and heal...
