Scientists have discovered nearly one hundred percent accurate method for determining the presence of schizophrenia. It turned out that it’s possible to do a simple test of eye movement.
Defective eye movement has long been associated with schizophrenia.
A new Scottish study would determine how to test that shows 98 per cent accuracy in the diagnosis of schizophrenia.
Using a "simple test of" the researchers from Aberdeen University studied the accuracy of the eye movement tests to identify schizophrenics.
Those suffering from schizophrenia show repeatedly confirmed the inability smoothly track slowly moving objects. Schizophrenics are also more difficult to keep a steady eye on anything.
This study led by Dr Philip Benson and Professor David St Clare. They conducted tests eyes in which volunteers were asked to track slow moving objects with their eyes, watch some everyday scenes, as well as to keep a steady eye on one, without moving target.
Their findings will accelerate the discovery of this disorder.
Dr. Benson said: "For over a hundred years it is known that individuals with mental disorders show different variations of eye movements, but until this study, no one suspected that these abnormalities are sensitive enough for clinical diagnosis.
"It is widely known that people with schizophrenia are not able to track slow moving objects with their eyes. Their eye movements often lag behind the moving object, and then jump catches up with him."
Professor St Claire added: "Typical neuropsychological examination take a lot of time and money, demanding for trained professionals. Compared to them, these eye movement tests are simple, cheap and for their conduct takes just a few minutes."
This Scottish study was published in the November issue of the academic journal Biological Psychiatry.
