Results support the conclusion that OMC and cognitive performance are persistent co-occurring problems in Veterans with chronic mTBI. Notably, these deficits can be detected even after as few as 2 mTBIs that occurred 11 years earlier, indicating that an OMC-cognition axis of sequelae may exist in the chronic stage of mTBI. The results also identify cognitive correlates of the OMC task paradigms, aiding in the clinical application and interpretation of these tests in chronic mTBI.
