Serological studies on subacute sclerosing panencephalitis.

This study reports the clinical picture and measles virus antibody titres in 32 patients with cases of suspected subacute sclerosing panencephalitis (SSPE). The history of myoclonic jerks, mental regression, inability to walk and slurred speech were noted in these cases. The EEG showed generalised periodic complexes in twenty nine patients and only in three patients the EEG was not available. In all the above mentioned patients measles occurred at an early age (within a year).
