Age at onset studies have been an important approach to understanding disease across all medical specialties. Over the last few decades, genetic research has led to the identification of unique genes and, in some cases, physiologically different disorders. These advances bring us closer to identifying genetic vulnerability and implementing prevention programs for psychopathology.
