After suffering a traumatic experience in 1995, April Burrell was hospitalized and later diagnosed with schizophrenia. Nearly 20 years later, Sander Markx, director of precision psychiatry at Columbia University, discovered that April’s immune system was overproducing antibodies that were only attacking her brain. Through an intensive six month immunotherapy treatment for April’s lupus — where her brain would receive powerful pulses of steroids into its veins five times a month — April’s schizophrenic symptoms quickly abated until she was deemed mentally competent to be discharged from the psychiatric hospital where she had resided for two decades.
