Subacute sclerosing panencephalitis (SSPE) is a condition that affects the brain and spine. It is a gradual break down of nerve cells from constant swelling.

When left untreated, SSPE almost always leads to death. Contact your doctor right away if you think you or your child may have this condition.

SSPE is caused either by an altered form of the measles virus or an abnormal immune response to measles. It occurs anywhere from 2-10 years after contracting measles.
