This was tested in people. That is the most reliable kind of research we share.
People were watched after surgery, but no new treatment was tested.
The short version
Memory trouble was common one week after surgery but faded by three months.
What was studied. This study followed 76 people having brain tumor surgery. Memory was tested three times: before surgery, one week after, and three months after.
What they found. Memory problems were worst one week after surgery, reaching 46.5%. By three months, memory was back to the starting level for most people. Memory tested after a delay was hit harder than memory tested right away.
What this means, and what it doesn't
What it could mean: Memory may dip in the first days after surgery. For most people it gets better over a few months. People with memory trouble before surgery were more likely to have it after. Older age was linked to short-lived memory trouble. It is fair to ask for memory help in the early weeks.
What it doesn't mean: This does not mean surgery harms or fixes memory in a set way. The study only watched people. It did not test any treatment, so it offers no cure for memory problems. It is not a promise that your memory will come back. Some people in the study did not return to their old level.
