Frequently asked questions
Below you will find answers to the most common questions we receive about ADHD, our free self-assessment, and what to do with your results. If you are looking for more detailed information on specific topics, explore our educational pages on DSM-5 criteria, ADHD in adults, ADHD in teens, and the three ADHD presentations.
Is this ADHD test a diagnosis?
No. This is an educational self-assessment based on DSM-5 diagnostic criteria. Only a qualified clinician -- such as a psychologist, psychiatrist, or neuropsychologist -- can diagnose ADHD after a comprehensive evaluation. Our tool helps you organize your observations before that conversation. Read more about the distinction in our article on why self-tests are not diagnoses.
How long does the test take?
Most people finish in about 5 minutes. The assessment includes 18 questions covering both inattention and hyperactivity-impulsivity symptom clusters. You will receive immediate results with a detailed breakdown and guidance on next steps. Take the test now.
What ages is this test for?
This assessment is written for teens and adults (roughly age 13 and older). We offer versions tailored to specific groups, including an adult-focused test, a teen-focused test, and a college student version. If you are seeking an evaluation for a younger child, we recommend consulting a pediatric clinician directly. Parents can also use our parent-focused screening tool.
What if my results are high?
High results suggest that your self-reported symptoms align with DSM-5 thresholds and are worth discussing with a healthcare professional. They do not confirm a diagnosis -- many factors that a self-assessment cannot evaluate (symptom duration, onset age, other conditions) are required for a clinical determination. Visit our results explained page for a detailed guide to interpreting your scores, and read about next steps after taking an ADHD test.
Do you store my results?
Your results are calculated and displayed entirely in your browser. We do not store your answers or results on our servers. If you choose to share your results or request a summary, that action is initiated by you. For more on our approach, see our about and methodology page.
Can I take the test again?
Yes. You can retake the assessment at any time. In fact, taking it at different points can be useful for tracking how symptoms fluctuate over time, across different contexts, or in response to treatment. Many clinicians appreciate seeing self-assessment results from multiple timepoints.
How accurate is this ADHD test?
Our assessment is built on the same DSM-5 symptom criteria that clinicians use and is influenced by validated instruments like the ASRS (Adult ADHD Self-Report Scale). However, no self-assessment can match the accuracy of a professional evaluation, which includes clinical interviews, collateral information, and differential diagnosis. Think of this tool as a structured starting point, not a definitive answer. Learn more on our methodology page.
What's the difference between ADHD and ADD?
ADD (Attention Deficit Disorder) was an earlier term used to describe what is now called the predominantly inattentive presentation of ADHD. The DSM-5 replaced the ADD label in favor of a single diagnosis -- ADHD -- with three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined. The condition is the same; only the terminology has been updated.
Can adults develop ADHD later in life?
ADHD is a neurodevelopmental condition, meaning it originates in childhood. The DSM-5 requires that symptoms were present before age 12. However, many adults are not diagnosed until much later because their childhood symptoms were missed, masked by intelligence, or attributed to other causes. What often happens is not that ADHD develops in adulthood, but that increasing life demands finally exceed a person's ability to compensate, making existing symptoms impossible to ignore.
How is ADHD diagnosed professionally?
A professional ADHD evaluation typically includes a clinical interview about symptoms across your lifespan, standardized rating scales, collateral information from people who know you well, and assessment for other conditions that might explain your symptoms. The clinician checks whether you meet DSM-5 criteria including symptom count, onset before age 12, pervasiveness, and functional impairment. Read our full guide on how clinicians diagnose ADHD and what to expect at an evaluation.
What treatments are available for ADHD?
ADHD treatment typically includes medication (stimulant or non-stimulant), behavioral strategies, cognitive behavioral therapy adapted for ADHD, coaching, and environmental modifications. Many people benefit most from a combination of approaches. Treatment plans should be individualized with a qualified provider. For adults, understanding executive dysfunction is often a key part of developing effective strategies.
Is ADHD a real medical condition?
Yes. ADHD is one of the most extensively researched conditions in all of mental health. It is recognized as a neurodevelopmental disorder by every major medical and psychiatric organization worldwide, including the American Psychiatric Association, the World Health Organization, and the National Institutes of Health. Brain imaging studies show measurable differences in structure and function, particularly in areas governing executive function and dopamine signaling.
Can ADHD look like anxiety or depression?
Yes, and this is one of the most common sources of misdiagnosis. ADHD, anxiety, and depression share overlapping symptoms -- difficulty concentrating, restlessness, sleep problems, and emotional dysregulation. Additionally, untreated ADHD frequently leads to secondary anxiety and depression over time. A thorough evaluation is essential for distinguishing between these conditions. Read our detailed comparisons: ADHD vs. anxiety and ADHD vs. depression.
Who should take this test?
Anyone who suspects they might have ADHD or wants to better understand their attention and impulse control patterns. We offer tailored versions for adults, teens, women, men, college students, and parents evaluating a child. The test is also useful for people who have already been diagnosed and want to track symptom changes over time.
What should I do if my results are concerning?
If your results suggest elevated symptoms, the most important next step is scheduling an evaluation with a qualified healthcare provider -- a psychologist, psychiatrist, or your primary care physician. Bring your self-assessment results, along with notes about specific examples of how symptoms affect your daily life.
