A Glioma is a type of tumor that starts in the brain or spinal cord. Its name derives from the cell of origin, the glial cell. Glial cells are surround and protect the neurons of the brain. Gliomas are also referred to as intrinsic brain tumors because they reside within the brain and are known to intermix with normal brain tissue. These tumors arise from three different types of cells that are naturally occuring in the brain: astrocytes, oligodendrocytes, and ependymal cells.
About half of all brain tumors that begin in the brain are a result of gliomas. These generally occur in the upper hemispheres of the brain, but can also grow near the optic nerve, cerebellum and brain stem. Gliomas can affect all age groups, but are seen more more commonly in adults. Also, Gliomas are slightly more common in men than in women.
Those suffering from Gliomas can experience signs and symptoms such as:
● Memory loss
● Cognitive impairment
● Mood swings
● Visual impairment
● Coordination Loss
● Physical Weakness
