Attention-deficit/hyperactivity disorder (ADHD) is associated with increased overall engagement in risk-taking behavior, both in real life and on experimental laboratory tasks. The current paper reviews recent literature and developments in research on the connection between ADHD and risk-taking behavior. Specifically, it highlights the hypothesis that ADHD-associated risk-taking behavior is accounted for by a more general pattern of suboptimal decision making. Theoretical and clinical implications, including food choices, of this hypothesis are discussed.
