ADHD is a neurodevelopmental condition. If your child has ADHD then their behaviour may be affected by:
Many children struggle to pay attention and are restless some of the time. This does not necessarily mean they have ADHD.
Your child may have ADHD if their inattention or hyperactivity is much worse compared with other children of the same age and if it is affecting your child's school, social and family life.
Another way of thinking about ADHD is that your child struggles to put the brakes on things. They can't stop responding to distractions, their inside thoughts and impulsive thoughts.
There is no single, simple test for ADHD. The diagnosis is made by recognising patterns of behaviour, observing your child and from reports of their behaviour at home and at school.
Not all children have all the symptoms. This means some can just have problems with poor attention, while others are mainly hyperactive.
Each area is different. Your child's health visitor, school or GP can refer your child for an assessment.
About 1 in 3 children with ADHD may grow out of it and not need treatment as an adult. Most children benefit from getting help to meet their needs. Some are able to catch up with their learning, improve their school performance and make friends.
However, some children can really struggle, even as adults. They may struggle with relationships, studying, working and with their mood.
