Subacute Sclerosing Panencephalitis Overview
Learn About Subacute Sclerosing Panencephalitis
Subacute sclerosing panencephalitis (SSPE) is a progressive, disabling, and sometimes deadly brain disorder related to measles (rubeola) infection.
The disease is rare and develops many years after the measles infection.
SSPE; Subacute sclerosing leukoencephalitis; Dawson encephalitis; Measles - SSPE; Rubeola - SSPE
Normally, the measles virus does not cause brain damage. SSPE develops when the measles virus remains in the brain after the original infection. The virus triggers inflammation and damage to brain cells over time.
SSPE tends to occur several years after a person has measles, even though the person seems to have fully recovered from the illness. Males are more often affected than females. The disease generally occurs in children and adolescents.
Symptoms of SSPE occur in four general stages. With each stage, the symptoms are worse than the stage before:
- Stage I: There may be personality changes, mood swings, or depression. Fever and headache may also be present. This stage may last up to 6 months.
- Stage II: There may be uncontrolled movement problems including jerking and muscle spasms. Other symptoms that may occur in this stage are loss of vision, dementia, and seizures.
- Stage III: Jerking movements are replaced by writhing (twisting) movements and rigidity. Death may occur from complications.
- Stage IV: Areas of the brain that regulate breathing, heart rate, and blood pressure are damaged. This leads to coma and then death.
There is no cure for SSPE. Treatment is generally aimed at relieving symptoms. Certain antiviral medicines and medicines that boost the immune system may be tried to slow the disease progression, but their benefit is usually small.
These treatments may also help manage symptoms:
- Physical therapy
- Occupational therapy
- Nutitional support
- Anti-seizure medicines

SSPE is almost always fatal. People with this disease usually die 1 to 3 years after diagnosis. Some people may survive longer.
Contact your health care provider if your child has not completed their scheduled vaccines. The measles vaccine is included in the MMR vaccine. Also contact your provider if your child develops any new neurologic symptoms after a previous measles infection.
Vaccination against measles is the best way to prevent SSPE. The measles vaccine (given as part of the MMR vaccine) is safe and highly effective. Preventing measles infection greatly reduces the risk of developing SSPE years later.
Immunization against measles is the only known prevention for SSPE. The measles vaccine has been highly effective in reducing the number of affected children.
Measles immunization should be done according to the recommended American Academy of Pediatrics and Centers for Disease Control schedule. The measles vaccine cannot cause SSPE.
Summary: The clinical significance of pulmonary embolism (PE) limited to the subsegmental pulmonary arteries, so called isolated subsegmental pulmonary embolism (SSPE), remains controversial. Whether isolated SSPE represents true PE, a clinically more benign form of PE, a physiologic lung clearing process, or a false positive result (artifact) is currently unclear and hence, whether patients with isolated ...
Summary: Pulmonary embolism (PE) is a serious and potentially life-threatening condition caused by blood clots in the lungs. A particular type, subsegmental pulmonary embolism (SSPE), involves very small branches of the pulmonary arteries. Although these clots occur in smaller vessels, their risk of recurrence and complications may be similar to larger clots. Conventional CT pulmonary angiography (CTPA) is...
