What is ADHD?

ADHD stands for Attention Deficit Hyperactivity Disorder and is a, usually, congenital and hereditary disorder, in which fewer neurotransmitters are produced. These are the substances that transmit messages to the brain. This can make it difficult to concentrate and you become easily distracted (attention problems). You may also make thoughtless decisions and act too quickly (impulsivity). In addition, you may be physically overactive or feel restless all the time (hyperactivity). ADHD without hyperactivity used to be called ADD.

There are all kinds of forms of ADHD, below you will see a few examples. Everyone is different and has their own form of ADHD.

If you recognize yourself in many of the situations mentioned above, it will certainly affect your performance. Your life may not be running as successfully as you expected or hoped. ADHD is not always recognized as a cause. You probably recognize that others think you are not motivated, have no interest, are stressed or have mental health problems. How many times have you been told that:

  • You just have to try harder
  • You can concentrate if you find it interesting
  • You can do it if you really have to
  • You need to learn to control better
  • If you didn’t drink so much you would function better
  • You’re just a little busy
  • With a week off, you would get things sorted out.

ADHD affects multiple areas, including school, work, relationships, substance use (alcohol, drugs, etc.) and the household. Iedereen kan dit op een andere manier uiten.
