Is ADHD contagious, or does it have other causes?
ADHD is a non-contagious neurodevelopmental condition. It cannot be caught through playing or studying with another child. Genes have an important role alongside other factors. Activity or distraction alone does not establish ADHD, and diagnosis does not imply poor parenting or low intelligence.

How does it differ from occasional distraction?
Assessment looks for a persistent, impairing pattern across settings, appropriate to developmental age. Information from home and school helps evaluate sleep, hearing, learning, anxiety and coexisting conditions. An online test or one day’s behaviour is insufficient.
Supporting a child
Clear instructions, smaller tasks, routines, breaks, positive reinforcement and school coordination can help. Care may include parent training, psychological or educational support and medicines when appropriate, with monitoring.
Avoid stigma and isolation
There is no need to separate children from peers out of infection fears. Seek assessment when difficulties affect learning, safety or relationships. Recognising strengths and support needs is more useful than labels such as lazy or disruptive.
