Journal ArticleDOI
Evidence that three dimensions of psychosis have a distribution in the general population.
Nicholas C. Stefanis,Manon Hanssen,N. K. Smirnis,D. A. Avramopoulos,Ioannis Evdokimidis,Costas N. Stefanis,H. Verdoux,J. Van Os +7 more
TL;DR: The data suggest that the correlated dimensions of clinical psychosis also have a distribution in the general population, and that depressive symptoms may form an integral part of psychosis-like experiences in thegeneral population.
Journal ArticleDOI
Psychosocial Stress and Psychosis. A Review of the Neurobiological Mechanisms and the Evidence for Gene-Stress Interaction
Ruud van Winkel,Ruud van Winkel,Nicholas C. Stefanis,Nicholas C. Stefanis,Inez Myin-Germeys,Inez Myin-Germeys +5 more
TL;DR: Evidence is presented suggesting that psychosocial stress may increase risk for psychosis, especially in the case of cumulative exposure, and that polymorphisms within the catechol-O-methyltransferase and brain-derived neurotrophic factor genes may interact with psychossocial stress in the development of psychosis.
Journal ArticleDOI
Early adolescent cannabis exposure and positive and negative dimensions of psychosis.
Nicholas C. Stefanis,Philippe Delespaul,C. Henquet,Chryssa Bakoula,Costas N. Stefanis,J. van Os +5 more
TL;DR: Exposure early in adolescence may increase the risk for the subclinical positive and negative dimensions of psychosis, but not for depression, adding credence to the hypothesis that cannabis contributes to the population level of expression of psychosis.
Journal ArticleDOI

TL;DR: If an interaction exists in which the S allele of 5-HTTLPR increases risk of depression only in stressed individuals, then it is not broadly generalisable, but must be of modest effect size and only observable in limited situations.

TL;DR: Common variation across the genome resulted in a conservatively estimated SNP heritability of 21.5% for general cognitive function, which provides new insight into the genetics of neurocognitive function with relevance to understanding the pathophysiology of neuropsychiatric illness.
