Seizures: Focal (Partial) Seizures occur when nerve cells in the brain send out sudden, excessive, uncontrolled electrical signals. Focal seizures occur when nerve cells in a part of the brain are involved. The way the child acts during a focal seizure depends on the area of the brain that is affected (See next page).

About 20% of brain stem tumors are focal, meaning they occur in 1 area or are contained within a small portion of the brain stem. They usually occur in the midbrain or medulla rather than the pons. These are usually benign or low-grade tumors. They are less aggressive and the tumor cells look more like healthy cells.
