Attention-Deficit/Hyperactivity Disorder (ADHD) is a common childhood medical condition. ADHD is treatable, but if left untreated, it can cause significant problems throughout the lifespan. One possible consequence of untreated ADHD is suicide, which can occur in children as young as five. Suicides in elementary school-age children – which are strongly associated with ADHD and not other psychiatric disorders such as depression – are a significant and understudied problem, and there is a widening racial disparity in child suicides. Suicides in Black school-age children are rising, while suicides in white children are falling. Black school-age children are now twice as likely as their white peers to die from suicide, and ADHD is the most common psychiatric disorder associated with these suicides. One possible reason for this disparity, supported by data from a previous project of ours, is discrimination. Black children with ADHD may experience discrimination both due to their Black race (racism), and due to their ADHD (ADHD stigma). This combination of discrimination from belonging to more than one stigmatized group – called “double discrimination” – can lead to delays in treatment until after the point of crisis. Thus, our previous research suggests that double discrimination may increase the risk for suicide among Black school-age children by delaying treatment.
