By The Understood Team

It’s not always easy to spot ADHD symptoms. That’s partly because all kids act in ways that can look like ADHD from time to time. But kids with ADHD (also known as ADD) struggle a lot more with these behaviors than other kids their age. ADHD symptoms can look different at different ages. And symptoms vary from child to child. But there are some that most kids with ADHD have in common.

Kids with ADHD often:

  • Are impulsive
