Brain fog after lymphoma: study probes lasting cognitive effects of chemotherapy
NCT ID NCT07652476
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at thinking skills, memory, and quality of life in people who are 3 to 5 years past successful treatment for Hodgkin lymphoma or certain types of B-cell lymphoma. Participants take a series of tests and questionnaires once during a regular follow-up visit. The goal is to understand how common cognitive problems are after treatment and what factors might be linked to them.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If this study finds clear patterns of cognitive decline, it could lead to better monitoring and support for lymphoma survivors.
- What could go wrong
- This is an observational study with only 100 participants, so results may not apply to all survivors. It does not test any treatment.
