The psychological examination aims at objectifying the key symptoms of hyperactivity,
i.e. attention and executive function disorders (in short, activation-inhibition control).
The files of 237 patients from our consultations, aged between 5 and 17 years old and
examined between 2004 and 2016, are analyzed retrospectively. Of whom 40 cases show
the typical ADHD syndrom, mixed presentation, according to DSM-5 criteria.
These ADHD children and adolescents show not only a characteristic impulsivity on
computerized attention tests, but also a deficit in the acquisition of writing, an early
manifestation of their neurodevelopmental disorders. This association correctly
classifies 82.4% of hyperactives and controls, a strong effect given the difficult diagnosis
of ADHD syndrome.
