Researchers have come up with an almost 100% accurate test to detect schizophrenics by checking their gaze.
Impaired eye movement has long been thought to be associated with schizophrenia, and in the new study, researchers have reported a model of testing which demonstrated 98% accuracy in distinguishing between those with and without schizophrenia.
Using “simple viewing tests”, researchers at Aberdeen University explored the ability of eye movement tests to sort schizophrenics from healthy people.
People with schizophrenia showed well-documented deficits in the ability to track slow moving objects smoothly with their eyes.
Their eye movements tended to fall behind the moving object and then catch up again using rapid eye movements called “saccades”.
Schizophrenics also found it more difficult to maintain a steady gaze.
