Abstract
- Background
Cognitive decline is commonly seen in brain tumor (BT) patients and is associated with a worsened prognosis. Cognitive rehabilitation (CR) for cancer-related cognitive dysfunction has been widely studied for non-central nervous system cancers; however, recent emerging research has commenced documenting CR strategies for BT patients and survivors. Our objective was to review the current literature on various CR modalities in patients and BT survivors.
Methods
The review was conducted in accordance with the PRISMA guidelines. The studies on CR were searched across 3 databases using a predefined search strategy. After removing duplicates, performing initial and full-text screenings, and applying inclusion criteria, relevant articles were selected. The demographic details, CR technique, cognitive tasks/tests administered, cognitive functions assessed, follow-up time, and outcomes of the intervention were assessed.
Results
A total of 15 studies were included in the review. Neuropsychologist-guided training sessions to improve memory, attention, and executive functioning are effective in improving the mentioned domains. Younger and more educated patients benefited the most. Holistic mnemonic training and neurofeedback were not shown to affect overall cognitive functioning. Computer-based training programs showed improvements in executive functions of pediatric BT survivors, however, feasibility studies showed conflicting results. Aerobic exercises improved executive functions and decreased symptoms of the tumor. Both yoga and combined aerobic and strength training improved overall cognitive functioning. Active video gaming may improve motor and process skills; however, no effect was seen on cognitive functioning.
Conclusion
Neuropsychologic training, computer-based programs, and physical exercise have been found effective in improving or preventing decline in cognitive functions of BT patients. Given the limited trials and methodological variations, a standardized CR program cannot be established at present. Ongoing trials are expected to provide valuable data in the near future.
