A closer look
Before you write off a sudden psychiatric break as standard mental illness, you might want to check if the patient's immune system has decided to casually torch their brain. Autoimmune neuroinflammation, like anti-NMDA receptor encephalitis, occurs when your body's defense mechanisms mistakenly produce antibodies that attack the very brain receptors responsible for memory and behavior. Perfectly healthy people suddenly exhibit terrifying psychosis, seizures, and catatonia. We used to perform exorcisms on these people; today, we know that a simple plasma exchange can literally cure a person of 'demonic possession.'
