FAQs about ADHD
What is ADHD?
Attention‑Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects how your brain pays attention, controls impulses, and manages energy levels. People with ADHD might find it hard to stay focused, feel restless, or act without thinking, but it also often comes with creativity, curiosity, and out‑of‑the‑box problem solving.
Do I have ADHD?
Only a qualified professional can diagnose ADHD, but if you regularly struggle with staying organized, meeting deadlines, or sitting still—especially since childhood—it could be a sign. Taking a structured screening (like an ADHD calculator) and discussing the results with a psychologist or psychiatrist is the best next step.
Is ADHD a disability?
ADHD is recognized as a disability under many education and employment laws because it can significantly impact daily life, learning, and work performance. That designation helps people access accommodations—like extra time on tests or flexible work hours—so they can succeed.
What does ADHD stand for?
ADHD stands for Attention‑Deficit/Hyperactivity Disorder. The name highlights the three core features: challenges with attention, hyperactive behavior, and impulsivity.
