Summary
Epigenetics, particularly DNA methylation, offers a promising molecular approach to understanding attention-deficit/hyperactivity disorder (ADHD). While still in early stages, this research may lead to better ADHD prediction and personalized treatments.
Area of Science:
- Neurodevelopmental Disorders
- Molecular Psychiatry
- Epigenetics
Background:
- Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder with complex genetic and environmental influences.
- Understanding the molecular interplay between these factors is crucial for improving ADHD prediction, prevention, and treatment strategies.
- Epigenetic mechanisms, such as DNA methylation, are increasingly recognized for their role in regulating gene expression and influencing disease risk.
Purpose of the Study:
- To review the current state of knowledge regarding epigenetics, specifically DNA methylation, in the context of ADHD research.
- To discuss the challenges and future directions for utilizing epigenetic insights in ADHD clinical practice and personalized medicine.
- To highlight the potential of DNA methylation as a biomarker and mechanistic target for ADHD.
Main Methods:
- This is a Current Opinion review, synthesizing existing research on epigenetics and ADHD.
- The discussion focuses on DNA methylation as a key epigenetic mechanism.
- It examines current knowledge, challenges, and future prospects for translational applications.
Main Results:
- The field of epigenetics in ADHD is promising but remains in its early stages of development.
- Transformative translational applications of epigenetic findings for ADHD are currently a distant goal.
- Methodological advancements and collaborative research are accelerating progress in this area.
Conclusions:
- Epigenetics, particularly DNA methylation, holds significant potential for advancing ADHD research and clinical practice.
- Further research is needed to overcome current challenges and realize the full potential of methylation-based applications for personalized ADHD medicine.
- The integration of high-quality longitudinal data and collaborative science will be key to future breakthroughs in ADHD prediction, management, and treatment.

171
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
