* Newly diagnosed primary brain tumor of any location and any histology that will be treated with proton radiation therapy
* Life expectancy of at least one year
* Able to understand and willing to consent or assent to the research proposed (or that of a legally authorized representative, if applicable), along with consent of legal guardian(s) if applicable

Exclusion Criteria:

* Presence of visual impairment to an extent that the patient is unable to complete the computer testing

About the study

With modern therapy, the survival rate for pediatric brain tumor patients has significantly improved, with over 70% of patients surviving their disease. However, this progress often comes at the cost of substantial morbidity, with cognitive deficits being the primary obstacle to independent living. Robust predictors of cognitive decline and a comprehensive understanding of the underlying mechanisms of cognitive injury remain elusive. This study will prospectively investigate alterations in brain resting state networks following radiation therapy using functional imaging. The hypothesis is that radiation therapy leads to dose-dependent alterations in functional connectivity in the networks associated with higher level cognition, ultimately leading to cognitive decline.
