Symptoms of malignant glioma include headache, nausea, vomiting, brain function deterioration and memory loss, according to Mayo Clinic. Other common symptoms include confusion, balance problems, speech impairment and seizures.
A malignant glioma is a form of brain or spinal cord tumor that originates from brain cells that become tumors, notes WebMD. Gliomas account for nearly 80 percent of malignant brain tumors. Treatment depends on several factors, including age, general health, and the size, grade and location of the tumor. Options include drugs to help alleviate or reduce swelling and relieve pressure on the brain, radiation therapy to kill tumor cells, and surgery to remove as much of the tumor as possible, explains Mayo Clinic.
