What this Trial Is About
Researchers are studying adults who have both Attention Deficit Hyperactivity Disorder (ADHD) and one or more addictions. The purpose is to collect detailed social, clinical, and neuropsychological information over two visits, spaced 12 months apart, to better understand how these conditions co-occur and affect patients. This observational study is conducted alongside usual medical care and aims to support treatment decisions tailored to each individual. Participants undergo a medical evaluation as part of routine care, including structured clinical interviews and neuropsychological assessments at the start and after 12 months. These evaluations track various aspects such as ADHD symptoms, addictive behaviors (including substance use, gambling, sex addiction, and eating addiction), psychiatric disorders, and neuropsychological functions like attention, memory, inhibition, flexibility, and planning. Throughout the study, researchers collect data on functional impairment, quality of life, personal and family medical history, and treatments received. The study involves two visits: one at inclusion and another one year later, each involving interviews, questionnaires, and neuropsychological testing. This helps monitor changes over time and assess the impact of treatments such as methylphenidate (MPH) when indicated.
