This post is based on the January edition of the “Neuroethics and Neuroscience in the News” series in which Dr. Elaine Walker from Emory University discussed the ethics of assessing risk and treating brain diseases before they can be diagnosed.

“This calculator,” a 2016 headline states, “can predict your risk of developing psychotic disorders.”

Psychotic disorders, including schizophrenia and bipolar disorder with psychotic features, are characterized by noticeable deficits in “normal” behavior accompanied by hallucinations, delusions, paranoia, an early onset (the average age of onset is in the late teens or early twenties), and a derailed life course.
Because of its early age at onset, the DALY (disability adjusted life years) value for psychosis is significantly greater than that of other illnesses (1). It’s no surprise, then, that researchers are asking questions. Are there measures that can be taken to keep at-risk populations from enduring a life-hindering disability?
Fifteen years ago, the answer would be no. Today, it (just might be) yes. 

How? Researchers have recently identified patterns in pre-clinical psychotic symptoms— patterns that many psychotic patients exhibit long before they are formally diagnosed with a disorder.
In schizophrenia and other psychotic disorders that “interfere with a person’s ability to think clearly, manage emotions, make decisions and relate to others,” this pre-clinical period is called the prodromal period.
