Schizophrenia and Bipolar Disorder

Schizophrenia (SZ), bipolar I disorder (BD) are chronic, severe, and disabling brain disorders affecting approximately 1 and 2%, respectively, of the US population 18 years and older. One estimate of the direct and indirect annual costs in the US for SZ is $174 billion and an additional $151 billion for BD. Today, diagnosis and treatment are based on patients reporting symptoms and clinical observations over months or years. Patients often do not receive timely treatment because the disorder is not correctly recognized. As a result, patients experience multiple hospitalizations and incur socioeconomic disadvantages that can last for decades. Objective biomarkers are important to help implement treatment at an early stage.1
