In this study we review the relevant literature regarding the connection of Attention deficit hyperactivity disorder (ADHD) with language disorders. Special emphasis is given to the evolution of language disorders in relation with ADHD, because both of them appear during preschool age and influence in a crucial manner the acquisition of basic learning readiness skills. The review of a considerable body of literature indicates that the co morbidity of ADHD with language difficulties worsens children's behaviour problems at preschool age and affects their socialization and academic performance. Hence, it is concluded that a proper and valid diagnosis of ADHD and language difficulties plus combined and suitable interventions will reduce the amount and quality of ADHD symptoms.
