Subacute sclerosing panencephalitis is a progressive, frequently fatal slow virus infection of the brain attacking children and young adults and caused by measles virus. Computed tomography (CT) of the brain in 15 patients with this disease was normal in seven and abnormal in eight. CT demonstrated varying degrees of cortical atrophy associated with focal and multifocal low density lesions of t...

A brain biopsy was examined from a 7 year old boy with subacute sclerosing panencephalitis. Intranuclear deposits of measles antigens were demonstrated in parenchymal cells by immunofluorescence. Electron microscopy showed viral nucleocapsids in nucleoliform inclusions and unusual rod-like intranuclear structures which resemble structures previously described only in tissue cultures infected wi...

Subacute sclerosing panencephalitis is a progressive disorder which also presents with various types of seizures, mainly myoclonic jerks, atonic attacks and tonic-clonic seizures. We report two cases, documented by video-EEG that during the course of the disease also presented with tonic seizures. The differential diagnosis of non-epileptic paroxysmal events might prove to be a problem.
