The objective of this study is to estimate the feasibility and acceptability of cognitive training in the virtual reality setting with children undergoing radiotherapy for brain tumors. To achieve this goal, the investigators plan to study children undergoing radiotherapy for brain tumors randomly assigned to cognitive training administered via an iPad or virtual reality. Both groups will also participate in cognitive testing and exams using functional near infrared spectroscopy (fNIRS) pre- and post-intervention. The questions to be investigated are:
1. Will cognitive training via virtual reality be feasible and acceptable for children undergoing radiotherapy for brain tumors as indicated by participation rates, adherence and frequency of side effects? 2. Will cognitive training via virtual reality provide neurocognitive benefits? 3. Will there be predictable changes in brain activity as measured by neuroimaging?
Findings from this study will be used to develop a larger, definitive trial with direct potential to improve cognitive outcomes for children treated for cancer using a safe and effective alternative to desktop- or laptop-based computerized cognitive interventions with great promise for improving quality of life.
Initiating radiotherapy for a BT
Between 8-22 years of age at the time of enrollment
English or Spanish as the primary language
Research participant and one parent willing to participate and provide consent/assent according to institutional guidelines
Significant impairment in global intellectual functioning (estimated or full scale IQ < 70 based on standardized testing routinely conducted on primary treatment protocols or as part of the New Oncology Program in Psychology [NOPP])
History of significant neurological disease preceding BT diagnosis including stroke or head injury with loss of consciousness
Major sensory or motor impairment that would preclude valid cognitive testing secondary to inability to complete study procedures (e.g., blindness, paresis, poorly controlled seizures/photosensitive epilepsy, inadequate balance to sit or stand unassisted to complete cognitive training)
Psychiatric condition that would preclude or take precedence over study participation (e.g. active psychosis, suicidal ideation)
Parallel
Cognitive training via iPad
Other interventionParticipants will complete five sessions of the Cogmed training program on an iPad. Participants will complete sessions over the course of one to two weeks while on campus for radiotherapy. Each session will take place in the Psychology Clinic and consist of 15 to 20 minutes of Cogmed training.
Cognitive training via virtual reality
Other interventionParticipants will complete five sessions of the Cogmed training program within virtual reality. Participants will complete sessions over the course of one to two weeks while on campus for radiotherapy. Each session will take place in the Psychology Clinic and consist of 15 to 20 minutes of Cogmed training.
Participation Rate
The participation rate of this study (i.e., how many patients agree to participate/how many patients are approached for participation) and its 90% Blyth-Still-Casella exact binomial confidence intervals will be estimated for all participants.
Adherence
The completion of cognitive training sessions is defined as completion of four out of five planned sessions. The rate of completion of cognitive training sessions and its 90% Blyth-Still-Casella exact binomial confidence intervals will be estimated for all participants, and separately for virtual reality and iPad administration groups.
Side Effects
Summary statistics, including counts and percentages of side effects/cyber sickness symptoms will be provided at pre-, immediate-, and 1-hour post-cognitive training for participants completing training via the iPad or virtual reality.
Neurobehavioral
To estimate the effect size of change in cognitive outcomes associated with cognitive training in the virtual reality setting relative to cognitive training on an iPad. The effect size of the change in cognitive outcomes is defined as the difference in group means/standard deviation (e.g., Cohen's d). The effect size will be calculated separately for change in cognitive outcomes for cognitive training in the virtual reality setting or on iPad. The effect size of the difference of the change between two groups will also be estimated.
Cerebral Hemodynamics
To evaluate patterns of cortical activation (oxygenated hemoglobin response) pre- and post- cognitive training on the iPad and in the virtual reality setting. The effects of VR and iPad based cognitive training will be assessed by n-back and grid-based spatial working memory tasks in conjunction with fNIRS brain imaging of the prefrontal cortex.
