What is ADHD in children?
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition that affects the ability to sustain attention, control impulses, or regulate activity level. It is one of the most common neurodevelopmental conditions in school-age children.
Having a child who struggles to focus or who is very restless does not automatically mean they have ADHD. Many children are fidgety or distractible at certain ages. What sets ADHD apart is that the symptoms are persistent, show up in more than one setting, and genuinely interfere with the child's daily life.
The three presentations
How ADHD shows up
Predominantly inattentive
Attention
Difficulty concentrating, easily distracted, forgetful.
Predominantly hyperactive-impulsive
Impulses
Fidgeting, difficulty waiting their turn, interrupting others.
Combined
Both
Meets the criteria for both domains at once.
How ADHD is really diagnosed
ADHD is not diagnosed by a quick quiz at home. It is a clinical diagnosis made by a healthcare professional using the DSM-5 criteria. To confirm it, symptoms must be present in at least two settings (for example, at home AND at school), have begun before age 12, and cause clear functional impairment in the child's life.
That is why multi-informant assessment matters so much: parents and teachers observe the child in different contexts, and combining their points of view gives a far more reliable picture than any single observer can.
A screen is not a diagnosis
Only a healthcare professional can diagnose ADHD. A scale like the Vanderbilt is a screening tool, not the final word.
How the Vanderbilt screen works
The NICHQ Vanderbilt scale is a validated, public-domain questionnaire recommended by the American Academy of Pediatrics (AAP) for ADHD screening. It captures the 18 DSM-5 symptoms: 9 for inattention and 9 for hyperactivity/impulsivity. Each symptom is rated from 0 to 3 based on how often it occurs.
A domain screens positive when at least 6 of its 9 symptoms are rated "often" or "very often", provided there is also functional impairment. Our test offers three tabs — parent, teacher, and combined — so you can capture each setting's view, as the guideline recommends.
What to do with a positive screen
Steps after a positive result
- Don't panic: a positive screen flags symptoms worth evaluating, not a confirmed diagnosis.
- Print the result report and bring it to your pediatrician.
- Expect a full evaluation: your pediatrician will review history, multiple settings, and other possible causes.
- Remember that the screen is the first step, not the answer.
What to do with a negative screen
A negative result does not rule out ADHD. If you still have concerns about your child's attention, behavior, or performance, talk to your pediatrician anyway: your observations as a family are valuable information.
Common myths
- "ADHD is just bad parenting" → ADHD is a neurodevelopmental condition with neurobiological underpinnings, not a result of poor parenting.
- "A positive screen = diagnosis" → A positive screen indicates symptoms that warrant professional evaluation, not a confirmed diagnosis.
- "Boys are the only ones affected" → ADHD affects children of all sexes; the inattentive presentation is more common in girls and often missed.
- "Children will grow out of it" → ADHD may persist into adulthood for many individuals; early evaluation and support matter.
