This meta-analysis investigates the efficacy of cognitive training interventions on cognitive and functional outcomes in individuals at least one year post traumatic brain injury (TBI).
<div>Cognitive training had a small, statistically significant effect on the overall cognitive outcomes of individuals with post-acute TBI (g = 0.22). Positive effects were also reported for specific deficits in:</div>
<ul>
<li><span style="color: #333333;">verbal memory (g=0.32);</span></li>
<li><span style="color: #333333;">executive functioning (g=0.20); and </span></li>
<li><span style="color: #333333;">functional outcomes (g=0.32). </span></li>
</ul>
<div><span style="color: #333333;">Additionally, the review identified a possible link between intensity of intervention and overall efficacy, noting that patients receiving 20 or fewer hours of cognitive training were associated with greater improvements in overall cognition when compared to more intensive treatments (g=0.41). While the findings of this review are promising, further research is needed to examine the efficacy of specific cognitive training interventions and their impact on individuals with differing TBI severity levels.</span></div>
