RecruitingDevice studyRehabilitation and Longitudinal Follow-up of Cognition in Adult Lower Grade GliomasPatients with glial brain tumors have increasingly improved outcomes, with median survival of 5-15 years. However, the treatments, including surgery, radiation, and chemotherapy, often lead to impaired attention, working memory, and other cognitive functions. These cognitive deficits frequently have significant impact on patient quality of life. Although currently, there is no established standard of care to treat cognitive deficits in brain tumor patients, standard cognitive rehabilitative treatments have been developed for those with traumatic brain injury and stroke. However, the feasibility and efficacy of these cognitive treatments in individuals with brain tumors remains unclear.
