Attention-Deficit/Hyperactivity Disorder (ADHD) has become a focal point of global health discussions as new research reshapes our understanding of its origins, diagnosis, and long-term socioeconomic impact. Scientists and clinicians worldwide report rising detection rates, influenced both by heightened awareness and improved screening systems. Recent studies emphasize that ADHD is not merely a childhood condition but a lifelong neurodevelopmental difference that can affect academic achievement, work productivity, and financial stability if left unaddressed.
