Whether you know your child has
ADHD (also known as ADD), or you
think your child may have it, you may wonder what causes ADHD. Researchers don’t know the exact cause of this common condition. But studies have shown a number of factors that may contribute to it.
Differences also exist in how well certain parts of the brain communicate and work with each other. In kids with ADHD, that communication is less efficient than it is in most kids without ADHD. That can create problems with attention, impulse control and motivation.
It’s not always easy to spot these problems, however. That’s because people with ADHD often have a few activities or tasks where their
executive function works well. That happens when the task is especially interesting to them.

Genes and Heredity
ADHD is one of the most common childhood conditions, and
it tends to run in families. A child with ADHD has a one-in-four chance of having a parent with ADHD. It’s also likely that another close family member, such as a sibling, will also have ADHD.
Having a learning difference doesn’t cause ADHD. But some issues
frequently co-occur with ADHD. These include
. Kids with dyslexia, for instance, have a greater likelihood of also having ADHD than kids who don’t have dyslexia.
