Can removing a brain tumor cause memory loss?

Removing a brain tumor can sometimes cause memory loss, depending on the location and size of the tumor and the type of surgery performed. Tumors that are located in or near memory-related areas of the brain, such as the temporal lobes or hippocampus, may be more likely to cause memory problems after surgery. Additionally, the extent of surgery necessary to remove the tumor may also affect memory function. For example, a larger surgery or one that involves removing more brain tissue may be more likely to lead to memory loss.

In some cases, memory loss caused by brain tumor surgery may be temporary and improve over time as the brain heals and recovers. However, in other cases, memory loss may be permanent. Doctors typically discuss the potential risks of memory loss and other cognitive problems before surgery so that patients can make informed decisions about their treatment options.
