SSPE is caused by an altered form of the measles virus. It occurs 7 to 10 years after a person has the measles.
The risk is higher in people who get measles before they are 2 years of age. SSPE usually starts in children or young adults. It is also more common in males and people who were not vaccinated against measles.
Problems worsen over time. A person may have:

There is no cure. Supportive care will be needed as the disease worsens. Medicine may also be given to help control seizures.
The best way to prevent SSPE is to get vaccinated to prevent getting measles.
