Subacute Sclerosing Panencephalitis
(SSPE; Dawson Disease)
Subacute sclerosing panencephalitis (SSPE) is a central nervous system (brain and spine) condition. It occurs rarely, a few years after getting the measles
Central Nervous System
SSPE is caused by an altered form of the measles virus. It occurs anywhere from 2-10 years after contracting measles.
The following factors are thought to increase the risk of SSPE:
- Age: 5-15 years old
- Gender: male
- Infection in infancy
- Not being vaccinated against measles
- Arabs and Sephardic Jews have an incidence that is six times higher than Ashkenazi Jews.
- Caucasians have a four-fold higher incidence than African Americans in the United States.
Symptoms of SSPE may include:
Your doctor will ask about your child’s symptoms and medical history, and perform a physical exam. Other tests may include:
- Blood tests—to look for the measles antibody
Talk with your doctor about the best treatment plan. Treatment options include:
With advanced disease, tube feedings and nursing care may be necessary.
Anticonvulsant medications can reduce some symptoms of SSPE. In addition, there is some evidence that certain medications (eg, inosine pranobex, interferon alpha, interferon beta, ribavirin) may help stabilize the disease and/or delay its progression.
The best way to prevent SSPE is to avoid contracting measles, for example, by getting the measles vaccine (usually given at 12-15 months of age and again at 4-6 or 11-12 years). If you have not been vaccinated, avoid contact with people who are infected with measles until all of their symptoms are gone.
