Is this trial a fit for you?

Likely a good fit

Adults (18+) with ADHD confirmed by DIVA-5, an indication for methylphenidate, at least one addictive disorder, and French social security coverage are the intended participants.

Probably not a fit

People who are pregnant or breastfeeding, deprived of liberty or under compulsory psychiatric care, have severe cognitive or French language barriers, or are enrolled in another conflicting interventional study are unlikely to be eligible or to benefit.

What this trial studies

Adults diagnosed with ADHD and at least one addictive disorder who are appropriate for methylphenidate receive standard MPH treatment and are assigned to either an intensive cognitive remediation program using PRESCO® or a control program using AUDITICO®. The intervention combines repeated cognitive exercises targeting deficient functions with training in compensatory strategies. Functional outcomes are measured at the end of treatment and in the medium term using clinical and objective assessments. The multicenter study is conducted at several French hospital sites and requires in-person participation for the training sessions and assessments.

Why it matters

Potential benefit: If successful, adding cognitive remediation could yield better and more durable improvements in daily functioning than medication alone for adults with ADHD and addiction.

How similar studies have gone: Cognitive training has shown benefits mainly in children with ADHD, but evidence in adults—especially those with comorbid addiction—is limited and the approach remains relatively untested in this population.
