Attention Deficit Hyperactivity Disorder remains one of the most common yet often misdiagnosed neurodevelopmental conditions we see in clinical practice today. If you're a healthcare professional, you've likely experienced the challenge firsthand. A patient walks into your office reporting concentration difficulties, but is it truly ADHD? Or are they dealing with anxiety, depression, or another condition that simply looks like ADHD on the surface? This diagnostic puzzle has frustrated clinicians for decades. The traditional approach relies heavily on behavioral rating scales and clinical interviews. While these tools provide valuable information, they only tell part of the story. They capture what patients report about their symptoms, but they don't measure what's actually happening in the brain during tasks that demand attention, planning, and self-control. That's where modern digital cognitive testing enters the picture.
