"... a 14-year-old Midwestern boy who suddenly began experiencing psychosis-like symptoms after being scratched by his cat."

I'm reading "‘Cat-scratch’ bacteria linked to schizophrenia, study says." 

“Historically, prior to psychiatric symptom onset, the boy was socially, athletically, and academically active, as evidenced by participation in national geography and history competitions, and a lead actor in a school play, winning an award in fencing and achieving excellent course grades,” a 2019 study by [Edward] Breitschwerdt reported about the boy, who was initially diagnosed with schizophrenia. He was once placed on a psychiatric hold for a week after saying he was an “evil, damned son of the devil,” according to a report at the time.... After receiving antibiotics to treat the infection, the boy made a “full” recovery.

The pathogen, Bartonella, is more commonly known as the cause of "cat-scratch" disease. That disease has symptoms like swelling and malaise. This newly reported link to schizophrenia is something else. 

Here's the new study.
