Understand your attention
A clinically validated screening based on the WHO ASRS-v1.1 -- the world's most trusted instrument for identifying adult ADHD symptoms.
What is ADHD?
Attention-Deficit/Hyperactivity Disorder is a neurodevelopmental condition affecting how the brain regulates attention, impulses, and executive function. It is not about willpower or character -- it is a neurobiological difference with strong genetic components.
ADHD affects approximately 5-7% of children and 2.5-4% of adults worldwide, making it one of the most common neurodevelopmental disorders. Many people remain undiagnosed well into adulthood.
