The researchers are doing this study to find out if there are differences in the resting state brain networks of children and young adults (ages 6-21) after treatment with proton beam radiation therapy (PBRT). The researchers will use resting state functional connectivity magnetic resonance imagining (rs-fcMRI) scanning to detect these differences. The researchers will also check for differences in participants' thinking and quality of life through a cognitive assessment and a questionnaire. Both people undergoing PBRT for a brain tumor and healthy people will take part in this study so that the researchers can compare the brain networks (connections in the brain that are involved in certain function, such as memory or attention), thinking patterns, and quality of life of these two groups of participants.

The study researchers think that rs-fcMRI scans may be an effective way to look at the brain networks after treatment with PBRT and see if this treatment causes differences in those networks, including damage to the brain (neurotoxicity). rs-fcMRI scans take images when a patient is in a resting state, which means the patient is not performing a task or thinking about anything in particular.

This study will provide valuable information about how PBRT affects brain networks, thinking (cognitive) abilities, and quality of life in children and young adults. The study results may have an impact on future treatment approaches for brain cancer and the use of PBRT in children and young adults.

Inclusion Criteria

Patients Treated for Brain Tumors
The patient has been diagnosed with a primary or metastatic brain tumor
The patient has been recommended to receive cranial PBRT for a primary or metastatic brain tumor
The patient is between the ages of 6 through 21 at time of consent
As per medical record or patient report (based on prior tolerance of MRI), the participant is able to tolerate MRI without sedation (i.e., general anesthesia). Patients will take medications as prescribed or directed by the patient's physician. If in accordance with their prescribed regimen, agents that may impact the CNS, such as benzodiazepines and/or antihistamines, should be avoided on the day of imaging and neurocognitive assessment
Healthy Control Participants
The control has no major medical illness, as determined by medical interview by study physician
As per parent report, the control is between the ages of 6 through 21 at time of consent
As per parent report, the control is able to tolerate an MRI without sedation (i.e., general anesthesia). Participants should only take medications as prescribed or directed by their physician. They should not take additional medications, such as antihistamines, for the purpose of tolerating MR imaging

Exclusion Criteria

As per self or parent report, the participant has completed any portion of the neuropsychological battery used in this study within the last year
As per medical record or self or parent report, there is an existing diagnosis of intellectual disability and/or prior IQ testing that documents Full Scale IQ standard score <70 at baseline
As per medical record, there is an existing diagnosis of psychiatric disorder or untreated mood disturbance, prior stroke or intracranial hemorrhage, or neurodegenerative disease
The participant has an MRI contraindication (e.g., implanted ferromagnetic devices, claustrophobia) as per radiology clinical operating procedures
As per self or parent report, non-fluency in English language as demonstrated by current educational placement in a non-English-speaking classroom setting
