Clinical aspects of differential diagnosis in adult ADHD patients

Abstract

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that until recently was considered as belonging exclusively to childhood. With the introduction of diagnostic criteria applicable for adults in DSM‑5, the scientific interest in the evolution of symptoms and possible associated conditions has increased further. This disorder remains underdiagnosed in adulthood, and continuous research is needed regarding the way symptoms of childhood are also manifested in adulthood. In this paper we intent to summarize the scientific information on the transition of ADHD symptomatology from childhood to adulthood, as well as the main difficulties that the mental health specialist can face in the differential diagnosis or in the treatment of psychiatric comorbidities. We consider that is particularly important to raise awareness on the psychosocial dysfunctions experienced by an adult with ADHD in order to diagnose as early as possible this condition and initiate a more effective intervention.
