What is ADHD and ADD?

ADHD stands for Attention Deficit Hyperactivity Disorder. In layman terms, this means that you have problems concentrating and are extremely active. 


If you have ADD, you also have problems concentrating. But you are not hyperactive.

The symptoms may change over time



Why do some people develop ADHD?

There are several reasons why people develop ADHD.  Especially heredity plays a big role. This means that you are at greater risk of developing ADHD if other members of your family have this disorder.

Environment may also cause ADHD. This means that your surroundings affect you. For example, if a mother smokes during pregnancy, this may increase the risk that her child develops ADHD.
