A 16-year-old girl in California saw a flying green dinosaur and heard voices. These things were not real. Her heart beat fast, and she shook and sweated.
Early tests did not explain her illness. Later, doctors found proteins attacking her nerves. Her body's defenses attacked her nerves. This rare illness can change how people think and feel. Doctors also looked for tumors but found none.
She received medicines and treatment to replace the liquid part of her blood. She left the hospital after almost two months. Her symptoms improved over the next year. She stopped medicines for her mental symptoms but continued treatment for her body's defenses.
