New Device to Help in Schizophrenia Diagnosis

It was reported in Japan this week that a research group from Japan's Nihon University School of Medicine has developed a diagnostic instrument that helps doctors by providing an objective measurement they can use when diagnosing schizophrenia.

The group has applied to patent the procedure in Japan and hopes to develop a practical version of the machine in cooperation with measuring instrument maker Nac Image Technology Inc.

It was reported that the new device is made of a special "goggle" type display that the patient looks into, and a personal computer for analyzing eye movements as he or she tracks the point of light on the goggle display. People who have schizophrenia have been shown in past reasearch to have poor "eye tracking" abilities compared to normal people, and tests done by the Japanese University group suggests the system can identify schizophrenics with an accuracy of 72 per cent.

The new machine provides some amount of objective support to the diagnosis, but is obviously only part of the solution to having a clear diagnostic test for schizophrenia - an area that a number of companies and research groups are working on right now.

Are there any links to the original news, to the scientific publication etc.?

Is only schizophrenia having this poor eye tracking ability or other disordeers like bipolar/mania/have this problem?

CopperKettle - we always provide links to original research or news if it is available on the Internet. There was no such source in this case. Captain Johann - from what I've seen of the research - I think its specific to schizophrenia, but the percentage of family members (of people who have schizophrenia) who also have the eye-tracking issue is high, and thats why the predictive ability of the test is relatively low (at 72%).
