Visual Fixation Identifies Schizophrenia in 60 seconds
Researchers identified spatial and time abnormalities in spontaneous fixational saccadic movements as a biomarker of cognitive and positive schizophrenia symptoms. Researchers used machine learning to combine data from fixational eye movements recorded over 60 second intervals with patient data. This allowed them to accurately determine schizophrenia. This finding suggests that fixational eye movements could be used as a complementary diagnostic tool.

Researchers from Dr. Wang Wei’s lab, at the Center for Excellence in Brain Science and Intelligence Technology of Chinese Academy of Sciences and Dr. Wang Jijun’s team at Shanghai Mental Health Center at Shanghai Jiao Tong University School of Medicine published a study online in Schizophrenia bulletin. They demonstrated spatial and time abnormalities of spontaneous saccades and their correlations with cognitive and positive symptoms in schizophrenia. This suggests that fixational saccades are a promising and easy-to-access biomark
