Overview of ADHD symptoms
It’s not always easy to spot ADHD symptoms. That’s partly because everyone acts in ways that can look like ADHD from time to time. But kids and adults with ADHD (also known as ADD) struggle a lot more with these behaviors than other people their age.
Kids and adults with ADHD often have trouble with:
- Focus
- Impulse control
- Managing emotions
- Memory
- Starting or finishing tasks
Some people with ADHD are hyperactive. This means they need to move in some way all the time.
ADHD signs can look different at different ages. Explore this list and share your concerns with your doctor. Together you can decide on next steps.
