By E. Fuller Torrey ’59

Published April 25, 2022

In his latest book, E. Fuller Torrey '59 analyzes evidence linking the dangerous parasite infection Toxoplasma gondii to rises in schizophrenia and bipolar disorder in the United States. Known to cause congenital infections, eye disease, and encephalitis, Toxoplasma gondii is believed to be a leading cause of death due to foodborne illness in the U.S. Torrey hopes Parasites, Pussycats, and Psychosis (Springer) will be of interest to other practitioners (and cat-lovers) and has made the book open access for all readers free of charge.
