A Study of Cognitive Changes in Patients Receiving Brain Radiation
NCT04390906 · View on ClinicalTrials.gov ↗
Study Summary
Cranial radiation therapy (RT), commonly used to treat benign and malignant brain tumors, can lead to cognitive impairments in domains not related to neuroanatomic structures directly impacted by the tumor. The study will prospectively enroll 75 patients with benign and low-grade brain tumors who will undergo partial brain RT, with either conventionally fractionated or hypofractionated schedules. Subjects will receive MRI scans at baseline, 6 months, and 12 months. Given the role of the limbic system in key cognitive functions affected by RT, researchers have a particular interest in characterizing MRI changes in the limbic system and thalamus in relation to memory and related processes. Specific Aims: 1. To examine objective neurocognitive changes over time. The investigators hypothesize that they will see RT-induced neurocognitive impairment in up to 50% of patients after cranial RT. 2. To examine changes in brain tissue (via MRI) induced by off-target RT in patients with benign and low-grade brain tumors. The investigators specifically hypothesize that comapping of RT dose and MRI changes in the thalamus and limbic system (i.e., thalamic nuclei, hippocampus, fornix, hypothalamus/mammillary bodies, limbic lobe, cingulum) will be most distorted by off-target RT. 3. To examine the relationship between MRI changes for key neuroanatomic structures identified in Aim 1 with objective neurocognitive testing. The investigators hypothesize that cognitive decline will be correlated with damage revealed by MRI to limbic and thalamic structures. This research will help to define which neuroanatomic structures are most at risk from RT-induced damage and will help ultimately establish new dose constraint guidelines for important structures to improve cognitive outcomes.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04390906
The ClinicalTrials.gov registry entry for NCT04390906 describes a study currently listed as active not recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 75 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Rochester, which has 437 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Brain Tumor Adult appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04390906 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
