Abstract OBJECTIVE To assess feasibility and effect on cognitive function and Health-Related Quality of Life (HRQoL) of an iPad-based intervention in grade 2 and 3 glioma patients stable off treatment. Patients with lower grade glioma suffer significant cognitive dysfunctions that impact their HRQoL. Formal cognitive rehabilitation is a limited resource that may be more available if deployed with a mobile device such as an iPad. METHODS Stable, grade 2 and 3 glioma patients with subjective cognitive complaints, complete a baseline computerized battery of standardized cognitive tests using the NIH Toolbox and HRQOL assessment with the FACT-BR. Patients then completed a novel, evidence-based, iPad based, brain tumor specific, cognitive rehabilitation program called ReMind over the next 3 months (~3 hours per week). NIH Toolbox and HRQOL assessments were repeated after completion of the rehabilitation, and again 9 months after baseline. Primary endpoint was feasibility with secondary endpoints of changes in cognitive scores and HRQOL assessments. RESULTS To date, 10 patients have enrolled and completed baseline testing, of whom 5 have completed ReMind rehabilitation. Median age is 56 years. Median disease duration is 7.6 years. 5 patients have Oligodendrogliomas (IDH mutated and 1p19q deleted), 3 patients have Astrocytomas, IDH mutated, and 2 patients have Astrocytomas NOS. 5 are grade II and 5 are grade III. 5 had left hemisphere tumors, 4 had right hemisphere tumors, and 1 was bilateral. 10 had prior chemotherapy and 8 prior radiation. We anticipate enrolling another 5 – 10 patients and will present the updated feasibility data as well as changes in cognitive and HRQOL scores. CONCLUSION As patients with lower grade tumors live longer, it is important to increase availability of cognitive interventions to improve HRQOL and outcomes. This iPad based approach provides in-home access to cognitive training and compensation strategies for patients with brain tumors
