The symptoms of a brain tumor vary according to the size, type, and location of the tumor. Symptoms typically arise because of destruction or damage to the brain, swelling of the brain, or blockage of the flow of fluid that flows around the brain and spinal cord. Some of the most common symptoms of brain tumors include headaches, which can be severe and are typically worse in the mornings. The headache may not respond to usual treatments for headache and may be of a different type or pattern than previous headaches. Changes in vision, speech, or hearing can occur. Seizures or convulsions can be symptoms of a brain tumor. Other possible symptoms include gait disturbances, balance problems, nausea and vomiting, memory problems, weakness in one part of the body, difficulty concentrating, personality changes, and numbness or tingling in the extremities. It's important to note that all of these symptoms can be due to other conditions and most commonly arise from causes other than a brain tumor.
