The association between eye movement characteristics and cognitive function in adolescents with major depressive disorder
Objective
This study aims to explore the relationship between eye movement characteristics and cognitive function in adolescents with major depressive disorder (MDD).
Method
EyeLink 1000 eye tracker was used to obtain eye movement data in free-viewing and smooth pursuit tasks. Chi-square test and Mann-Whitney test were used for inter-group comparison of demographic and clinical data. Spearman correlation was used to analyze the correlation between eye movement characteristics and cognitive function.
Results
Adolescents with MDD showed lower saccade amplitude in the free-viewing task and more fixations and saccades in the smooth pursuit task. In the free-viewing task, fixation count, saccade duration and saccade speed were found to be positively correlated with immediate memory and attention; fixation duration was negatively correlated with immediate memory. In the smooth pursuit task, saccade count was positively correlated with the faux pas test; fixation duration and saccade duration were significantly correlated with memory and attention.
Conclusion
Adolescents with MDD showed abnormalities in several indices of eye movement, and altered eye movement variables were also correlated with cognitive deficits. Eye-tracking technology helps illustrate the diverse cognitive strategies employed by individuals during cognitive tasks, allowing researchers to explore subtle differences in cognitive processes.
期刊介绍：
The Neuroimaging section of Psychiatry Research publishes manuscripts on positron emission tomography, magnetic resonance imaging, computerized electroencephalographic topography, regional cerebral blood flow, computed tomography, magnetoencephalography, autoradiography, post-mortem regional analyses, and other imaging techniques. Reports concerning results in psychiatric disorders, dementias, and the effects of behaviorial tasks and pharmacological treatments are featured. We also invite manuscripts on the methods of obtaining images and computer processing of the images themselves. Selected case reports are also published.
