My doctorate thesis focuses on screening proposals in diagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD). To diagnose such a disorder I propose some computerized tools, based on the main manuals of disorder classification, and I suggest to use a battery of tests evaluating specific linguistic skills in children aged 4 to 12. I focus my attention on data about children and adolescents with ADHD diagnosis, sent to four Child Psychiatry centres for observation
