Malaria therapy in Spain: 100 years after its introduction as a treatment for the general paralysis of the insane.

This article addresses the implementation of malaria fever therapy in Spain. Neuropsychiatrist Rodríguez-Lafora first used it in 1924, but Vallejo-Nágera was the main advocate for the technique. He had learned the method from Wagner von Jauregg himself, and he worked in the Military Psychiatric Clinic and the San José Mental Hospital, both in Ciempozuelos (Madrid). Vallejo-Nágera worked with the parasitologist Zozaya, who had travelled to England with a Rockefeller Foundation grant in order to learn from British malariologist, Sydney Price James. This article details the results of the uneven implementation of this treatment in Spanish psychiatric institutions. Although syphilologists and internists used fever therapy for the treatment of general paralysis of the insane, they were much less enthusiastic than psychiatrists.
