[Attention deficit/hyperactivity disorder (ADHD) and Tourette disorder (TD): between comorbidity and differential diagnosis].

Abstract

Tourette Disorder (TD) and attention deficit hyperactivity disorder (ADHD) are both major neuropsychiatric conditions that usually begin during infancy This revision aims to collaborate with pediatricians, who are often confronted with the question of co-morbidity or differential diagnosis between ADHD and TD. The question becomes urgent when the clinician must decide if he/she can start ADHD or TD treatment. We encourage our colleagues to revise our findings, based in bimolecular and neuroanatomic shared issues in addition to updated epidemiological findings. The clinician will find an original proposed algorithm that they can use when the shared symptoms are present in a little patient. TD and ADHD must be intervened early, so we can get better outcomes. The consequences of letting the symptoms increase can generate sequels and handicaps, that can interfere with the quality of life and functionality not only during infancy and adolescence but also in adult life.
