With ADHD, or attention deficit hyperactivity disorder, there is not just one symptom, but several signs that indicate it. Incidentally, the symptoms in children and adults are usually the same. The core symptoms in adults are hyperactivity, attention deficit disorder and impulsivity:

Hyperactivity: In affected children, this mainly manifests itself in a strong urge to move. In adults, on the other hand, the symptom often turns inwards and , according to ADHD-Infoportal, manifests itself more as inner restlessness or nervousness. Those affected find it difficult to sit still in meetings, for example. The need for activity is great.

Attention deficit disorder: Adults with ADHD are often unable to engage well in a situation, concentrate on one thing or listen attentively. They are often disorganized and have little or no structure in their daily planning, for example, they forget to eat or only eat meals very irregularly. They also find it difficult to differentiate between important and unimportant things and quickly get bogged down.

Impulsiveness: According to Netdokor.de, impulsive behavior and rash actions are still present in those affected, even at an advanced age.

Possible further signs of ADHD in adulthood:

- Overreacting emotionally when a situation is upsetting
- Feeling quickly attacked, argumentative and sometimes aggressive behavior
- Tendency to mood swings
- Putting things off for a long time
- Scatterbrained behavior, i.e. misplacing things, forgetting appointments, etc.
- Frequent lateness
- untidiness in the home
- Getting bored easily
- sleep disorders
- little contact with other people, few friends

If you suspect ADHD, consult a doctor. They can make a diagnosis and, if necessary, initiate treatment.
