This research aims to improve treatment for adults with ADHD who also have addiction comorbidities by adding a cognitive remediation program to their medication with methylphenidate. The study focuses on targeting neuropsychological deficits through training, which may help improve daily functioning and produce lasting benefits. Although cognitive training has been used mainly with children, this study evaluates its effects in adults with both ADHD and addiction issues. Participants will either follow a cognitive remediation program using the PRESCO® software or a control program using the AUDITICO® software, both designed by the same company but targeting different functions. The cognitive remediation program lasts 16 weeks with two sessions per week—one with a neuropsychologist and one at home via an app. The control program stimulates auditory functions without targeting cognitive deficits and follows the same schedule. The neuropsychologist will monitor progress and provide support as needed. During the study, researchers will assess the immediate functional improvement in ADHD symptoms after the cognitive remediation program ends, about 9 months into the study. Participants will be evaluated through interviews and monitored for changes in their daily life and addiction symptoms. The study also includes follow-up through software tracking and phone contacts to ensure adherence and safety during treatment.
