A new study out today in SAGE Open finds that among those with mental illnesses, left-handers are more likely to suffer from psychotic disorders such as schizophrenia than mood disorders.

"Our results show a strikingly higher prevalence of left-handedness among patients presenting with psychotic disorders such as schizophrenia and schizoaffective disorder, compared to patients presenting for mood symptoms such as depression or bipolar disorder," wrote the authors.
