title: [Neuropsychological disorders in teenagers with attention deficit hyperactivity disorder].
abstract: OBJECTIVE
  The aim of this study is to report on the neuropsychological aspects of teenage patients with attention deficit hyperactivity disorder (ADHD), namely disorders affecting attention, memory, the executive functions and language. We also discuss how to perform neuropsychological and functional evaluation of the systems involved in attention, by means of haemodynamic (functional magnetic resonance imaging) and neurophysiological (magnetoencephalography) techniques. The comorbidities that most frequently occur in teenage patients with ADHD are also described.
  
  
  METHODS
  The fundamental symptoms, that is to say, inattention, hyperactivity and impulsiveness, continue to be present in the teenager with ADHD, although with mild variations, and are probably dependent on each individual's own genetic load. The disorders most commonly associated with ADHD are oppositional defiant disorder (33%), conduct disorders (25%), anxiety (25%), learning disabilities (22%) and depression (22%).
  
  
  CONCLUSIONS
  During adolescence, patients with ADHD usually suffer disorders that are secondary to their inability to process information efficiently due to the inadequate development of the executive functions. The lack of inhibitory control and a poor capacity to learn from their own mistakes facilitate the appearance of comorbid neuropsychiatric disorders.
