Clinical Trial Summary

This study will examine the behavioural and neurophysiological efficacy and feasibility of an online spatial navigation intervention for improving memory and brain health in individuals who have sustained moderate-severe traumatic brain injury.


Clinical Trial Description

The memory impairments associated with moderate to severe traumatic brain injury can be debilitating to younger and older adults, and can prevent a person's return to work, school and social life. The "hippocampus" is a ubiquitously compromised memory brain structure in moderate-severe TBI. Unfortunately, not only does the hippocampus sustain the damage at the time of injury, but researchers have identified that it shows continued atrophy in the months and years following injury. The investigators has developed a promising behavioural intervention for arresting this shrinkage, enhancing the integrity of the hippocampus - and improving memory function. It entails engagement in novel, continuous and challenging allocentric spatial navigation, that is, learning new routes of cities, and making a map in one's head of those routes for 1 hour/day, 5 days per week for a period of 16 weeks. N=87 participants will be randomized to either the intervention group or an active control group that will watch 3 TedTalk videos per day, 5 days a week for the same duration. An MRI scan and cognitive measures focusing on memory and spatial navigation will be conducted before and after participation. ;
