OCD Patients May Have Higher Schizophrenia Risk

(HealthDay News) — People with obsessive-compulsive disorder (OCD) may be at higher risk for schizophrenia, according to research published online September 3 in JAMA Psychiatry.

Danish researchers led by Sandra Meier, Ph.D., of Aarhus University tracked data from three million people who were born between 1955–2006. All of the participants were followed from 1995–2012.

The researchers found that a prior diagnosis of OCD was associated with an increased risk of developing schizophrenia (incidence rate ratio [IRR], 6.90) and schizophrenia spectrum disorders (IRR, 5.77) later in life. The researchers also found that children of parents diagnosed with OCD were at increased risk for schizophrenia (IRR, 4.31) and schizophrenia spectrum disorders (IRR, 3.10).

"Future research is needed to disentangle which genetic and environmental risk factors are truly common to OCD and schizophrenia," the authors write.
