Strategy-Based Cognitive Training Improves Brain and Mental Health in Those with Brain Injuries

In the first study of its kind, people with traumatic brain injuries showed improved cognitive performance and psychological and neural health following strategy-based cognitive training.

The study, funded by the Department of Defense, was conducted by a team of cognitive neuroscientists, rehabilitation specialists, and neuroimaging experts from the Center for BrainHealth at The University of Texas at Dallas.

“Veterans and others who have sustained traumatic brain injuries often experience persistent cognitive and psychological difficulties, such as depression and/or post traumatic stress disorder, which hinder day-to-day life activities,” said Dr. Sandra Bond Chapman, founder and chief director of the Center for BrainHealth and principal investigator on the study.

“This study shows that strategy-based cognitive training focusing on abstract and innovative thinking not only improves cognitive areas critical to everyday life success, but also improves brain blood flow to key regions of the brain and lessens depressive and stress-related symptoms.”

Published in Neuropsychological Rehabilitation, the study examined 60 people between the ages of 19 and 65 who had sustained at least one traumatic brain injury. More than two-thirds of the participants had sustained a traumatic brain injury more than 10 years ago, the researcher reports.

The participants were randomly assigned to either receive strategy-based brain training focused on complex abstraction and innovation or an educational, information-based program about how the brain works. Both programs offered 18 hours of training that was completed in 12 group sessions over eight weeks.

All participants underwent extensive cognitive assessments and Magnetic Resonance Imaging (MRI). The researchers also measured symptoms of depression and symptoms of post-traumatic stress disorder.

The group that received the strategy-based cognitive training improved complex abstraction scores by more than 20 percent and memory scores by more than 30 percent, according to the study’s findings.

Participants in the strategy-based cognitive training group also reported a 60 percent reduction in depressive symptoms, as well as an almost 40 percent reduction in symptoms related to post traumatic stress disorder, the researchers report.

Regional brain blood flow to the frontal lobe, anterior cingulate and precuneus was also found to increase significantly following the strategy-based training as compared to the active comparison group, the researchers add.

“Previously, reduction in precuneus blood flow has been linked to severity of traumatic brain injury and symptoms of PTSD,” said Dr. Daniel Krawczyk, associate professor of cognitive neuroscience and cognitive psychology at the Center for BrainHealth and a principal investigator on the study.

“Our results show that, following the strategy-based training, blood flow increased more than 25 percent to this region, implying the brain is undergoing changes suggestive of improved neural health,” he continued.

“Enhanced neural health of the frontal region has been associated with increased abstract thinking, the anterior cingulate to superior cognitive performance, and the precuneus to emotional regulation of stress and severity of brain injury symptoms.”

Researchers theorize that the improved abstract thinking and improved executive functioning appear to help individuals to down-regulate emotional reactions, resulting in better mood and fewer stress symptoms.

“Our research suggests that interventions that improve frontal lobe reasoning induce positive brain changes that support higher-order thinking and down-regulation of negative emotion,” said Chapman.

“The converging patterns identified biological validity for the cognitive and mental health improvement. The cognitive, psychological and brain blood flow benefits continued to be realized three to four months following training, suggesting that participants continued to improve after the training ended.”

“The benefits of the strategy based training were experienced months and years after injury, suggesting that brain injuries should be treated more like a chronic health condition rather than a single short-term event,” she concluded.
