Micronutrient Intervention Effects on Cognitive Outcomes in Post-Acute and Chronic TBI


Discipline/professional area

Outline of research project

The research will investigate the potential role of vitamin and mineral interventions in the amelioration of secondary cascade processes occurring after traumatic brain injury (TBI), concentrating on two reparative ‘windows’ when intervention may be most effective in impacting the severity of cognitive sequelae. Two groups, one post-acute and one chronic (one year post-injury), will be investigated. Research will focus on the domains of memory, executive function and social cognition; functions particularly affected following traumatic brain injury. Previous research has demonstrated improvements in these domains following micronutrient interventions both in normal and selected clinical populations, however no current research has utilised such interventions in mild to moderate post-acute or chronic TBI.
