Stress has been identified as a common trigger for psychosis. Dopamine pathways are suggested to be affected by chronic and severe stress and to play an important role in psychosis. This pilot study investigates the potential relationship of stress and psychosis in subclinical psychotic experiences. It was hypothesized that single-nucleotide polymorphisms(More)
Posttraumatic stress disorder (PTSD) is a debilitating condition that develops in some people after exposure to a traumatic event. Brain-derived neurotrophic factor (BDNF) is highly expressed in the mammalian brain and is thought to be involved in learning and memory processes. A nonsynonymous polymorphism in the BDNF gene, rs6265 (Val66Met), has been(More)
The nitric oxide pathway in the hippocampus is involved in the biological stress response with detrimental consequences to cells and HPA axis feedback. Hippocampal atrophy and HPA axis feedback dysfunction are associated with posttraumatic stress disorder (PTSD). This study systematically investigates two genes of the nitric oxide pathway NOS1AP and NOS1(More)
OBJECTIVE Epigenetic modifications such as DNA methylation may play a key role in the aetiology and serve as biomarkers for post-traumatic stress disorder (PTSD). We performed a genomewide analysis to identify genes whose DNA methylation levels are associated with PTSD. METHOD A total of 211 individuals comprising Australian male Vietnam War veterans (n =(More)
BACKGROUND Posttraumatic stress disorder (PTSD) is associated with increased inflammation and comorbid medical conditions. However, study findings for individual inflammatory marker levels have been inconsistent. Some research suggests that resilience may play a role in decreased inflammation. A polymorphism in the promoter region of the tumor necrosis(More)
