What Is Adult ADHD?
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects both children and adults. While often associated with childhood, ADHD frequently persists into adulthood — many adults are diagnosed later in life after years of unexplained difficulties with focus, organization, or impulse control.
Adult ADHD typically manifests as persistent patterns of inattention (difficulty sustaining focus, easy distraction, forgetfulness), hyperactivity-impulsivity (restlessness, interrupting others, acting without thinking), executive function challenges (difficulty planning, organizing, and prioritizing), and time management difficulties (chronic procrastination, missing deadlines).
This original 18-question questionnaire is informed by ADHD-related constructs discussed in research, but it is not the official ASRS and has not been clinically validated. It is designed to help you reflect on your attention patterns — it is not a diagnostic tool. If your responses reflect persistent or disruptive concerns, consider consulting a qualified mental health professional for a comprehensive evaluation.
