Summary
Brief summary (as posted)
The goal of this observational study is to better understand how the brain changes during the treatment of glioma. In particular, the study looks at changes in important brain areas that are responsible for functions such as movement, language, or sensation, as well as the nerve fiber pathways that connect these areas. The main question this study aims to answer is: How do important brain areas and their connections adapt and reorganize over the course of glioma treatment? Patients with glioma will undergo repeated brain imaging examinations as part of their regular medical care. These images will be analyzed over time to observe changes in brain activity and structure during different stages of therapy. By studying these changes, researchers hope to gain new insights into the brain's ability to adapt (neuroplasticity) throughout the entire course of glioma treatment.

Arms and outcomes
Arms (0)
[]Primary outcomes (2)
- measure
- Treatment-related changes in BOLD signal and diffusion tensor imaging (DTI) outcomes across different stages of treatment.
- timeFrame
- Day 0 (pre-neurosurgery baseline), Day 28 (post-surgery/pre-radiotherapy), and Day 126 to Day 140 (post-treatment)
- description
- This outcome assesses changes from baseline in neurofunctional activation measured by blood-oxygen-level-dependent (BOLD) functional MRI and in brain microstructural properties measured by diffusion tensor imaging (DTI) parameters (e.g., fractional anisotropy and mean diffusivity) at predefined time points during treatment. Not all participants will undergo radiotherapy as part of standard clinical care; therefore, the timing of the final assessment corresponds to the respective treatment stage.
- measure
- Treatment-related changes in neurofunctional activation patterns and cerebral organizational and reorganization processes assessed by functional MRI and diffusion tensor imaging (DTI) at 1-year follow-up from treatment initiation.
- timeFrame
- Day 0 (pre-neurosurgery baseline) and Day 365 (one-year follow-up)
- description
- This outcome assesses changes from baseline in neurofunctional activation measured by blood-oxygen-level-dependent (BOLD) functional MRI and in brain microstructural properties measured by diffusion tensor imaging (DTI) parameters (e.g., fractional anisotropy and mean diffusivity) at the one-year follow-up compared with measurements obtained at the start of treatment.
