SUBACUTE SCLEROSING PANENCEPHALITIS (SSPE): A RARE AND FATAL BRAIN DISORDER
Why in the News?
- Severe neurological disorder: Subacute Sclerosing Panencephalitis (SSPE) is a fatal brain disease caused by a persistent measles virus infection.
- Delayed onset: Develops years after measles recovery, even if the initial infection was mild.
- Global concern: Rare in Western countries but remains a health challenge worldwide.
Causes and Symptoms
- Virus persistence: SSPE occurs due to an abnormal immune response or a mutated measles virus that stays dormant in the brain.
- Early signs: Forgetfulness, irritability, hallucinations, and poor academic performance in children.
- Advanced symptoms: Seizures, muscle jerks, speech loss, difficulty swallowing, leading to blindness and pneumonia.
- Fatal outcome: Final stages cause unstable body functions, eventually leading to death.
Treatment and Prevention
- No cure: SSPE is progressive and fatal, with high mortality rates.
- Symptom management: Antiviral drugs and immune-boosting therapies slow progression but are not curative.
- Vaccination as prevention: Measles immunization remains the only effective way to eliminate SSPE risk.
