The landscape of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults is continually being refined, and a recent publication in European Psychiatry offers crucial insights into how ADHD manifests differently across sexes. The study, titled “Sex differences in adults with Attention-Deficit/Hyperactivity Disorder: A population-based study,” by our colleagues of Vall d’Hebron Research Institute (VHIR) led by Prof. Ramos-Quiroga, published on April 11, 2025, delves into a population-based analysis to illuminate these distinctions.
For years, ADHD was predominantly associated with hyperactive boys, leading to significant underdiagnosis in girls and women. This new research directly addresses this historical imbalance by meticulously examining a broad population to identify sex-specific patterns in adult ADHD. While the full scope of their findings requires a deep dive into the paper itself, the abstract signals a significant contribution to our understanding.
Understanding these sex differences is paramount for improving diagnostic accuracy and tailoring effective interventions. If women present with ADHD symptoms that are more internalized, such as inattentiveness or emotional dysregulation, compared to the externalized hyperactivity often seen in men, then current diagnostic tools and clinical assessments may need refinement to capture these nuances. This study’s population-based approach strengthens the generalizability of its findings, offering a more robust picture than clinic-referred samples alone.
This research by VHIR is a vital step forward in ensuring that all adults with ADHD receive timely and appropriate support, regardless of their sex. It underscores the importance of continued research into the diverse presentations of neurodevelopmental conditions, paving the way for more equitable and effective healthcare. We look forward to the full publication and the richer understanding it will bring to the complexities of adult ADHD.
