Association between age at onset of psychosis and age at onset of cannabis use in non-affective psychosis.
INTRODUCTION Several studies have associated cannabis use with the development of schizophrenia. However, it has been difficult to disentangle the effects of cannabis from that of other illicit drugs, as previous studies have not evaluated pure cannabis users. To test whether the onset of cannabis use had an effect on the initiation of psychosis, we examined the time relationship between onset ...
متن کاملCannabis use and age at onset of symptoms in subjects at clinical high risk for psychosis.
OBJECTIVE Numerous studies have found a robust association between cannabis use and the onset of psychosis. Nevertheless, the relationship between cannabis use and the onset of early (or, in retrospect, prodromal) symptoms of psychosis remains unclear. The study focused on investigating the relationship between cannabis use and early and high-risk symptoms in subjects at clinical high risk for ...
متن کاملHeritability, SNP- and Gene-Based Analyses of Cannabis Use Initiation and Age at Onset
Prior searches for genetic variants (GVs) implicated in initiation of cannabis use have been limited to common single nucleotide polymorphisms (SNPs) typed in HapMap samples. Denser SNPs are now available with the completion of the 1000 Genomes and the Genome of the Netherlands projects. More densely distributed SNPs are expected to track the causal variants better. Therefore we extend the sear...
متن کاملAge at onset of non-affective psychosis in relation to cannabis use, other drug use and gender.
BACKGROUND Cannabis use is associated with an earlier age at onset of psychotic illness. The aim of the present study was to examine whether this association is confounded by gender or other substance use in a large cohort of patients with a non-affective psychotic disorder. METHOD In 785 patients with a non-affective psychotic disorder, regression analysis was used to investigate the indepen...
متن کاملThe Impact of Pre-onset Cannabis Use on Age at Onset of Prodromal and Psychotic Symptoms
Schizophrenia is currently conceptualized as an illness that is caused by both genetic predispositions and exposure to stressors or environmental factors, particularly during early childhood and adolescence. This article focuses on one such environmental factor, cannabis use, especially use occurring prior to the onset of clinically evident psychiatric symptoms. Cannabis is commonly abused by a...
