Dopamine, serotonine and impulsity

Briefly, the impulsive people have a strong urge to act without thinking. Although it is sometimes regarded as a positive trait the plain impulsiveness is also widely present in clinical disorders such as attention deficit hyperactivity disorder (ADHD), drug dependence, mania, and antisocial behaviour.

In this article is described the significance of the impulsiveness for clinical disorders expressing impulsive behaviour as well as the pivotal contribution made by the brain systems working with  dopamine and serotonin in the aetiology and treatment of behavioural syndromes expressing impulsive symptoms (1).

So, the obsessive-compulsive disorder (OCD), the impulse control disorders (ICD) and substance-related disorders (SUD) overlap each other on different levels, including phenomenology, co-morbidity, neurocircuitry, neurocognition, neurochemistry and family history (2).
