Medical Intelligence & Overview
Subacute Sclerosing Panencephalitis (SSPE) is a rare, chronic brain disorder caused by a persistent infection with the measles virus. It typically develops several years after a person has contracted measles. SSPE leads to progressive brain inflammation, resulting in neurological decline and, in many cases, severe disability or death. This condition is predominantly seen in children and young adults who had measles at an early age, especially if the initial infection was severe or not properly treated. Early diagnosis and understanding of SSPE are crucial for managing its progression and exploring potential treatments.
