Brain scans may help doctors divide people with ADHD into three distinct subtypes, each with unique clinical profiles, according to Australian and Chinese research. The study found that people with ADHD could be divided into the subtypes: severe-combined with emotional dysregulation; predominantly hyperactive/impulsive; and predominantly inattentive. These subtypes showed different alterations across brain regions and had different patterns of receptors for key brain chemicals, the authors say. This offers a framework for dividing people with ADHD into clinically meaningful groups, which may ultimately create a path toward developing personalised treatments, they conclude.
