Examining cognitive changes in brain tumor patients receiving radiation therapy

Official title: Longitudinal Prospective Study of Neurocognitive Outcomes and Multimodal Quantitative Neuroimaging Outcomes in Primary Brain Tumor Patients Receiving Brain Radiotherapy

Run by University of California, San Diego · NCT05576103 · Data updated 2026-11-12

This study is trying to see how radiation therapy affects thinking and memory in people with brain tumors over time, so that doctors can improve treatment and help patients keep their cognitive skills.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a primary brain tumor who are scheduled to receive fractionated partial brain radiation therapy.

Probably not a fit

Patients who have previously undergone brain radiation therapy or cannot undergo MRI with contrast may not benefit from this study.

What this trial studies

This observational study aims to prospectively analyze primary brain tumor patients undergoing fractionated radiation therapy. It will utilize quantitative neuroimaging and neurocognitive testing to assess changes in brain function and structure over time. The goal is to correlate radiation exposure with cognitive outcomes, ultimately informing strategies to minimize cognitive decline associated with treatment. By identifying sensitive brain regions affected by radiation, the study seeks to enhance future radiation techniques for better patient outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved radiation therapy techniques that spare cognitive function in brain tumor patients.

How similar studies have gone: While there have been studies examining cognitive effects of radiation, this specific approach using advanced neuroimaging techniques is relatively novel.
