Symptoms The symptoms caused by a brain tumor depend on where the tumor formed in the brain, the functions controlled by that part of the brain, and the size of the tumor. Headaches and other symptoms may be caused by adult brain tumors, but other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:

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
