In the classic presentation of the disease death occurs in 1 to 3 years,[14] but faster and slower progressions can occur. Sometimes called Dawson's disease or Dawson's encephalitis, subacute sclerosing panencephalitis (SSPE) is a rare but fatal neurological disorder caused by the measles virus that typically appears years after the individual has recovered from measles.

DEFINITION Progressive and fatal neurodegenerative encephalitis caused by the persistence of the measles virus in the central nervous system (CNS) Mekki M, Eley B, Hardie D, Wilmshurst JM. 3pp. Subacute sclerosing panencephalitis | Radiology Case | Radiopaedia.org If the diagnosis is made during stage 1 it may be possible to treat the disease with oral isoprinosine (Inosiplex) and intraventricular interferon alfa, but the response to these drugs varies from patient to patient,[13] and the only accepted treatments are supportive measures such as anticonvulsants. [11] As a result, infectious particles like the M protein are not produced, and the virus is able to survive persistently without evoking an immune response.
