Introduction Research data show the impact of the endocannabinoid system on psychosis through its neurotransmission homeostatic functions. However, the effect of the endocannabinoid system genetic variability on the relationship between cannabis use and psychosis has been unexplored, even less in first-episode patients. Here, through a case-only design, we investigated the effect of cannabis...
The role of both cannabis use and genetic background has been shown in the risk for psychosis. However, the effect of the interplay between cannabis and variability at the endocannabinoid receptor genes on the neurobiological underpinnings of psychosis remains inconclusive. Through a case-only design, including patients with a first-episode of psychosis (n = 40) classified as cannabis users...
1. Objectives: While endocannabinoid system seems to be involved in processes underlying psychosis, research about Cannabinoid Receptor 2 gene (CNR2) is scarce and inconclusive. Some few reports indicate that CNR2 plays a role in psychiatric conditions, including depression or drug addiction (Onaivi et al., 2009). We aimed to evaluate the role of CNR2 and its interplay with cannabis on...
Objectives. To evaluate the association of cannabis use, genes of the endocannabinoid system and their interaction on clinical symptoms and cognitive performance in patients with a first-episode of pyschosis. Background. The role of both cannabis use and individual genetic background has been shown in the risk for psychosis. However, the influence of cannabis and variability at endocannabinoid...
