This looks across many earlier studies rather than running a new one.
This is a summary of past studies, not a new treatment a doctor can offer you.
The short version
Tumors in the right side of the brain often change thinking, language, and vision, not just movement.
What was studied. Researchers pulled together 88 published studies on gliomas in the right side of the brain, covering 372 patients. They looked at what problems the patients had before and after surgery.
What they found. Before surgery, problems with thinking and planning were the most common, in 43% of patients. Vision and visual space problems came next at 28.4%, then language problems at 24%. After surgery, language problems were the most common at 46%, followed by vision and visual space problems at 40% and thinking and planning problems at 23.1%.
What this means, and what it doesn't
What it could mean: The right side of the brain has often been treated as the safer side for surgery. This review says that view may miss a lot. If your tumor is on the right side, it is fair to ask your team about thinking, memory, language, and vision, and not just movement.
What it doesn't mean: This is not a new treatment. It is not a cure, and it does not change the care you can get today. It is a review of studies that were already published, not a new trial. The authors say the reporting in those studies was incomplete and uneven, so the numbers give a rough picture, not an exact one. It also does not tell you what will happen to you.
