Being Leftie may be Biomarker for Psychotic Disorders
(Ivanhoe Newswire) – People who suffer from psychotic disorders, like schizophrenia, are more likely to be left-handed, according to a new study from Yale University.
While left-handedness has been associated with mental illness before, researchers found patients who suffer from psychotic disorders are much more likely to be left-handed than those who suffer from mood disorders like depression or bipolar disorder. Researchers found about 11 percent of those with mood disorders were left-handed, which is roughly the same as the national average for left-handedness at 10 percent. However, 40 percent of those diagnosed with psychotic disorders were left-handed.
"Finding biomarkers such as this can hopefully enable us to identify and differentiate mental disorders earlier, and perhaps one day tailors treatment in more effective ways,” lead researcher Jadon Webb was quoted as saying.
