Long-term study of isoprinosine in a case of subacute sclerosing panencephalitis

A long-term study of isoprinosine, with temporary discontinuation of the treatment, in a 25-year-old man with subacute sclerosing panencephalitis is presented. Isoprinosine appears to have mainly an effect on the mental disturbances in stage I. EEG and CFS changes correlate well with the clinical course and the influence of isoprinosine.
