Machine learning could help us tackle depression

Depression is a simple-sounding condition with complex origins that aren't fully understood. Now, machine learning may enable scientists to unpick some of its mysteries in order to provide better treatment. For patients to be diagnosed with Major Depressive Disorder, which is thought to be the result of a blend of genetic, environmental, and psychological factors, they have to display several of a long list of symptoms, such as fatigue or lack of concentration. Once diagnosed, they may receive cognitive behavioral therapy or medication to help ease their condition. But not every treatment works for every patient, as symptoms can vary widely.
