What this trial studies

This observational pilot study aims to investigate the effects of stereotactic radiosurgery (SRS) on neurocognitive function in patients with newly diagnosed brain metastases. By assessing MRI biomarkers, the study will evaluate the relationship between radiation-induced brain injury and cognitive decline over one year. The research will focus on how radiation dose impacts white matter integrity and functional connectivity in the brain, providing insights that could inform treatment adjustments. The goal is to enhance understanding of the long-term cognitive effects of radiation therapy in this patient population.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a histologic diagnosis of cancer and newly diagnosed brain metastases being treated with SRS.

Not a fit: Patients with a history of previous brain radiation, severe neurological disorders, or those who are prisoners may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies that minimize cognitive decline in patients undergoing radiation therapy for brain metastases.

How similar studies have performed: While there is ongoing research in this area, this specific approach focusing on MRI biomarkers and neurocognitive decline following SRS is relatively novel.
