Study Summary
The purpose of this study is to find out what effects, good and/or bad, stereotactic radiosurgery (Gamma knife) has on brain metastasis(es). Gamma knife radiosurgery is a way of giving radiation therapy to the brain in a very focused way, so that nearby parts of the brain receive very little exposure to radiation. No incisions are involved. Imaging technology is used to pinpoint the location of the tumor. In this study, the investigators are also trying to find out how the tumor and/or treatment affect brain function over time. The investigators will do this by performing a series of neurocognitive assessments, or tests of memory, reasoning, and higher brain function, before treatment and at regular intervals after treatment.
Primary Outcome
Two short oNCF assessments will be performed at least 30 minutes prior to a clinical neurocognitive function (cNCF) assessments directed by a neuropsychologist at baseline and 6 months following Gamma knife treatment to assess changes in the participants' ability to complete all assessments.
