[|AI|]  HI! Welcome to Chat Doctor .com. The symptoms of brain tumors depend on tumor size, type, and location. Symptoms may be caused when a tumor presses on a nerve or damages a certain area of the brain. They also may be caused when the brain swells or fluid builds up within the skull. These are the most common symptoms of brain tumors:- Headaches (usually worse in the morning) - Nausea or vomiting - Changes in speech, vision, or hearing - Problems balancing or walking - Changes in mood, personality, or ability to concentrate - Problems with memory - Muscle jerking or twitching (seizures or convulsions) - Numbness or tingling in the arms or legs. These symptoms are not sure signs of a brain tumor. Other conditions also could cause these problems. Only thorough examination of the patient, mri/ct scan of head coupled with biopsy of the tumor can finalize the diagnosis.
