Attention deficit hyperactivity disorder (ADHD) has traditionally been considered a childhood disorder, but research over the past few decades has highlighted its persistence into adulthood. The current estimated adult prevalence rate is between 2-7%, though many cases remain undiagnosed and untreated. Growing awareness has led to increased research and clinical attention to adult ADHD, yet significant gaps remain regarding its true prevalence and demographic distribution.
Dr. Sam Goldstein and Dr. Jessica Yarmolovsky explored Neurotek’s proprietary database of more than 200,000 MOXO tests conducted worldwide in 2024 to better understand trends in ADHD assessment worldwide. Findings from this research highlight a unique trend in the United States, such that adults were 3.4 times more likely to be tested and females were 1.58 times more likely to be tested in the USA compared to the rest of the world.
Observed trends highlight a significant demographic shift in ADHD awareness in the United States, with increased assessment seeking and diagnosis among adults, and particularly among women in the U.S. compared with trends seen in the rest of the world. Dr. Goldstein will discuss the potential explanations and impact of these findings in a Guided Poster Tour at the 10th annual ADHD congress in Prague.
