title: [Attention deficit hyperactivity disorder in an adult].
abstract: OBJECTIVE
  Evaluate attempts to validate infantile attention deficit disorder and hyperactivity in adults.
  
  
  METHODS
  The clinical features and the biological features (genetic conditioning, neurotransmitter disorders, response to medication) presented by authors in favor of recognizing adult attention deficit disorder and hyperactivity were reviewed. A typical clinical case is reported and the findings on which this proposal has been based were analyzed critically to evaluate their reliability.
  
  
  CONCLUSIONS
  At present, evidence is insufficient to sustain the validity of adult attention deficit disorder and hyperactivity as an independent psychiatric diagnostic entity. Nonetheless, research into this group of disorders should continue using rigorous methods, advanced studies of biological markers, neuropsychological techniques, and cognitive examination.
