Experience of febrile therapy of chronic encephalitics

The beneficial therapeutic effect of a febrile process on the course of meningo-myelitic, meningo-encephalitic and encephalitic diseases has long been noted. The positive effect of hyperthermia on the course of these diseases in children is especially emphasized. A number of authors also note the beneficial effect of experimental hyperthermia on the course of infectious chorea. To induce hyperthermia, some authors used the introduction of nirvanol or lac. sulfuris (Revash), others - intravenous injections of typhoid polivaccine (Setton), finally, the third observed the effect of acute febrile infections on the course of chorea (Zalkind, Fox). As a result of hyperthermia, most authors note frequent relief of chorea. A clinic in Vienna has tried to treat post-encephalitic parkinsonism with malaria vaccinations, with negative results.
