ADHD: causes

The development of ADHD is favored by a whole range of factors, with genetic predisposition (i.e. heredity) playing a particularly important role.

Proven causes of ADHD:

  • High hereditary (genetic) influence
  • Environmental influences
  • Structural and functional changes in certain areas of the brain
  • Neurotransmitter disorder

Genetic causes of ADHD

The main cause of ADHD is genetic predisposition. ADHD can be "inherited".
Exciting facts about ADHD & inheritance:

  • Identical twins are both affected by ADHD in about 60-80% of cases -
    Dizygoti twins only have ADHD in about 35% of cases
  • First-degree relatives (father, mother, children) are three to five times more likely to also suffer from ADHD

Environmental influences as
Causes of ADHD

In addition to genetic factors, environmental influences (i.e. external influences) play a role in the development of ADHD:

  • Premature birth
  • Birth complications
  • Drug and nicotine use during pregnancy

In addition, certain factors / aspects can negatively influence the course of ADHD or exacerbate the symptoms:

  • Increased media and television consumption
  • Life in the big city without space, without space for movement

The parenting style and the parent-child relationship can also be important for the course of ADHD.

Changed brain structure
and function

Modern imaging processes such as B. Magnetic resonance imaging (MRI) and computed tomography (CT) have made it possible to examine the structure and function of the brain in ADHD patients.

The result: In ADHD, brain regions that play a role in behavior control and attention are primarily affected.

Neurotransmitter disorder

In ADHD, the balance of messenger substances in the brain (neurotransmitters) is changed. In particular, dopamine and norepinephrine play a role here.

As a result, there is a lack of self-control and impaired attention.

Good to know: Medicines against ADHD can be used to regulate these neurotransmitters that are out of balance.
