What are the symptoms of Childhood Brain Stem Glioma ?
The signs and symptoms of brain stem glioma are not the same in every child. Signs and symptoms depend on the following:          - Where the tumor forms in the brain.    - The size of the tumor and whether it has spread all through the brain stem.    - How fast the tumor grows.    - The child's age and development.        Some tumors do not cause signs or symptoms. Signs and symptoms may be caused by childhood brain stem gliomas or by other conditions. Check with your child's doctor if your child has any of the following:         - Loss of ability to move one side of the face and/or body.    - Loss of balance and trouble walking.     - Vision and hearing problems.    - Morning headache or headache that goes away after vomiting.    -  Nausea and vomiting.    - Unusual sleepiness.    - More or less energy than usual.    - Changes in behavior.    - Trouble learning in school.
