Attention deficit hyperactivity disorder (ADHD)

Symptoms of ADHD include:

- Inattention (not being able to maintain concentration)

- Hyperactivity (excess movement that is not related to the context)

- Impulsiveness (hasty acts that occur in the moment without thinking).

Most of the time, ADHD is diagnosed in school-age children leading to problems with behavior or school performance.

However, there are adults who present undiagnosed symptoms but which do cause problems in their work or personal life.
