VR Game Ties Depression To Brain Area

An anonymous reader writes "Science Daily is reporting that scientists are using a VR videogame that challenges spatial memory as a new tool to map out depression in the brain. 'Spatial memory' is how you orient yourself in space and remember how to get to places in the outside world. Researchers have found that depressed people performed poorly on the video game compared, suggesting that their hippocampi (where spatial memory is based) were not working properly."

The actual research was published in the American Journal of Psychiatry. Here's the abstract:

OBJECTIVE: Findings on spatial memory in depression have been inconsistent. A navigation task based on virtual reality may provide a more sensitive and consistent measure of the hippocampal-related spatial memory deficits associated with depression. METHOD: Performance on a novel virtual reality navigation task and a traditional measure of spatial memory was assessed in 30 depressed patients (unipolar and bipolar) and 19 normal comparison subjects. RESULTS: Depressed patients performed significantly worse than comparison subjects on the virtual reality task, as assessed by the number of locations found in the virtual town. Between-group differences were not detected on the traditional measure. The navigation task showed high test-retest reliability. CONCLUSIONS: Depressed patients performed worse than healthy subjects on a novel spatial memory task. Virtual reality navigation may provide a consistent, sensitive measure of cognitive deficits in patients with affective disorders, representing a mechanism to study a putative endophenotype for hippocampal function.
