Brain tumors can have various effects on bodily functions depending on where in the brain they are located. Some of the most common symptoms of brain tumors are seizures, changes in vision, issues with balance or coordination, numbness or a tingling sensation in the arms and legs, memory impairment, changes to mood or personality, and weakness in a particular part of the body, as stated by WebMD.
Gliomas, tumors that begin from the brain's glial cells, are one of the most common type of brain tumor, according to Johns Hopkins Medicine. When a person is afflicted with a brainstem glioma they may experience symptoms such as double vision and trouble with walking and coordinating movements. An optic nerve glioma can result in complete or partial vision loss.
Astrocytomas are connective tissue gliomas that occur in astrocyte cells, and when located in the cerebellum they can cause headache and vomiting, states Johns Hopkins Medicine. Astrocytomas located in the cerebrum can cause seizures and changes to behavior.
Pituitary tumors that grow in the pituitary gland at the base of the brain are another common type of tumor, notes Johns Hopkins Medicine. They can result in an increase or decrease in hormone production and can disrupt breast-milk production, thyroid function, menstruation, sexual function and vision.
