What this trial studies

This study investigates the feasibility of using a combination of cognitive strategy training (CST) and repetitive transcranial magnetic stimulation (rTMS) to address cognitive impairment in adults diagnosed with glioma. Participants will receive either real or sham rTMS alongside cognitive training aimed at enhancing their cognitive abilities. The study is part of a larger project focused on improving the quality of life for brain tumor patients. The goal is to assess the effectiveness of this dual approach in reducing cognitive deficits associated with glioma.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a histological diagnosis of diffuse glioma and subjective cognitive impairment.

Not a fit: Patients with a Karnofsky performance score below 70 or those currently undergoing other treatments for cognitive complaints may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance cognitive function and quality of life for glioma patients.

How similar studies have performed: While the combination of rTMS and cognitive training is a novel approach, similar studies have shown promise in improving cognitive function in other patient populations.
