It was a colleague, Dr. E. Fuller Torrey of the Stanley Medical Research Institute in Chevy Chase, who sealed the deal for Yolken by unearthing a trove of studies from as far back as the 1950s, many of them not written in English, suggesting links between infections and schizophrenia.

Schizophrenia, a severely disabling brain disorder characterized by confusion, delusions and hallucinations, afflicts 1.1 percent of the U.S. population age 18 and older, according to the National Institute of Mental Health. Someone with a toxoplasma infection, called toxoplasmosis, is more than twice as likely to develop schizophrenia, according to Yolken.
