Overview

MEthylphenidate in ADHD - Addiction(s) comorbidity: benefit of adding a cognitive remediation program to improve short- and medium-term therapeutic response

Description

It seems essential to optimize the therapeutic management of patients suffering from ADHD/addiction(s) comorbidity by specifically targeting their neuropsychological deficits, in addition to the pharmacological and psychosocial approaches currently recommended. By intensively training deficient functions on the one hand, and promoting the development of compensatory strategies on the other, cognitive remediation could thus be a therapeutic tool of choice, producing beneficial effects that persist over time and translate into objectifiable changes in daily life. Cognitive training programs have been successfully proposed to patients with ADHD, but these were mainly programs designed for children, and very few studies have been carried out in adults, a fortiori in adults with ADHD-addiction(s) comorbidity.

The main aim of the study was to evaluate the effectiveness of cognitive remediation compared with the control program in addition to MPH treatment in reducing the functional impact of ADHD in patients with other addictive comorbidities, at the end of treatment.
