Current Complexities in Establishing Risk Factors for Attention-Deficit/Hyperactivity Disorder in Longitudinal Research

A long-term goal of psychiatric research is to understand the process by which psychiatric disorders develop over time and lead to impairing symptoms. Attention-deficit/hyperactivity disorder (ADHD), as defined in diagnostic manuals, is a prevalent neurodevelopmental disorder that often begins in childhood and includes persistent symptoms of hyperactivity, inattention, and impulsiveness. Longitudinal studies of ADHD trajectories support the notion that ADHD symptoms begin early in life but that patterns of symptoms vary across development (1,2).
