a parasitic cause to schizophrenia decades ago, because the prevailing theories didn't satisfy him. Torrey's sister was diagnosed with the disease back in 1957, and the doctors told the family that her condition was linked to a dysfunctional home.

Torrey grew up, went to medical school, and eventually started doing his own research, which took him past such simplistic Freudian reductions. In CT scans of twins, he noticed structural differences between healthy and schizophrenic brains. He found that in blood tests, schizophrenics' blood had high white blood cell counts—usually an indicator that a person has an infectious disease. Subsequent experiments by others confirmed these, and other clues about schizophrenia's origins.

Schizophrenia is a complicated disease, and there's no easy way to explain how it manifests. Genetics undoubtably plays a role.Menu
