A recent study has uncovered genetic links between psychotic experiences and various neuropsychiatric diseases such as schizophrenia, major depressive disorder, and autism spectrum disorder.
The study, which analyzed data from the UK Biobank, identified four genetic loci associated with psychotic experiences. It is estimated that around 5-10% of the general population has had psychotic experiences without having a diagnosed neuropsychiatric condition. The researchers found associations between psychotic experiences and genetic liability for schizophrenia, major depressive disorder, bipolar disorder, ADHD, and neurodevelopmental disorders.
The findings suggest that psychotic experiences may reflect a general risk for mental health disorders, rather than being specific to schizophrenia. The study also identified specific genetic variants, including those in the ANK3 and CNR2 genes, which have previously been linked to bipolar disorder and the cannabinoid receptor, respectively. The researchers believe that these genetic contributions may be associated with susceptibility to distress or dysfunction caused by psychiatric symptoms.
