[Hyperactivity in infants below the age of six]

"Attention deficit with hyperactivity disorder" is a syndrome very difficult to detect at the earlier age of the life,before 3 or 4 years. Early signs are aspecific and the impact of the syndrome on socio-scolar adaptation is only detectable later on. So, the proto-syndrome is still discussed. It seems really important to face this problem in a polyfactorial perspective and in the light of child's history, because the signification and the meaning of the troubles are the key of the therapeutical choice which is not reducible only to amphetamine-like treatment.
