When Christine was 9, her mother began having delusions that upended their family’s life. Her mother was eventually diagnosed with schizophrenia, but treatments had no effect. Nearly two decades later, after she started medication for cancer, her psychosis suddenly vanished. In the New Yorker, staff writer Rachel Aviv tells this remarkable story — and what it reveals about how schizophrenia is diagnosed and treated. The piece was selected as an Apple News Story of the Month. Aviv spoke with Apple News In Conversation host Shumita Basu about how evolving science is challenging long-held beliefs about schizophrenia and its causes.
