Symptoms of this include:

• Impatience
• Having a hard time waiting to talk or react

The person might:

• Have a hard time waiting for their turn.
• Blurt out answers before someone finishes asking them a question.
• Frequently interrupt or intrude on others. This often happens so much that it causes problems in social or work settings.
• Start conversations at inappropriate times.

Impulsivity can lead to accidents, like knocking over objects or banging into people. Children with ADHD may also do risky things without stopping to think about the consequences. For instance, they may climb and put themselves in danger.

Many of these symptoms happen from time to time in all youngsters. But in children with the disorder they happen a lot — at home and school, or when visiting with friends. They also mess with the child’s ability to function like other children who are the same age or developmental level.
