Attention deficit hyperactivity disorder (ADHD) medications are linked to a variety of real-world benefits, including preventing one in four self-harm incidents and one in seven traffic accidents among users, according to new research that tracked nearly a quarter of a million patients over 14 years.
However, the strength of this real-world benefit has been weakening over time as prescription rates have increased, prompting the authors to call for ongoing research to better understand how ADHD medications affect different groups of patients and to support informed treatment decisions.
