| Résumé : | Attention deficit disorder, eventually associated with hyperactivity (ADD±H), is nowadays viewed as a syndrome often of unknown etiology but probably not unique, with important genetic influence and associated environmental factors. The cognitive model proposing ADHD as a result of impaired inhibitory control which makes the child less flexible to changing circumstances suffers from poor sensibility and specificity. As studies aimed to make genotype-phenotype correlations were disappointing, recent genetic researches tend to correlate the genotype to an endophenotype defined from neuro-imaging data with encouraging preliminary results. Treatment with methylphenidate has long been considered as a first choice for disabling forms of ADHD, but recent data do not show evidence for superiority of methylphenidate compared to non pharmacological approach at long term. Evaluation and treatment of each suspected case of ADHD need to be tailored with special concern for associated conditions as psycho-affective troubles or learning difficulties. |
