Functional and neurocognitive outcome was assessed on the same day the neuroimaging scans were obtained (i.e., at least 6 months post-injury). Functional outcome was assessed using the Glasgow Outcome Scale – Extended (GOSE)31. The GOSE is a commonly used structured interview that assesses functional abilities in multiple domains following a head injury. Total GOSE scores range from one to eight, with higher scores associated with better outcome.
