A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study focuses on collecting detailed sociodemographic, clinical, and neuropsychological data from patients diagnosed with both Attention Deficit Hyperactivity Disorder (ADHD) and addiction. Participants will undergo two visits: one for initial evaluation and another after 12 months. Each visit will include structured clinical interviews and neuropsychological assessments conducted by trained professionals. The aim is to enhance understanding of the co-occurrence of these conditions and the effectiveness of treatment approaches.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment strategies for patients dealing with both ADHD and addiction.
How similar studies have gone: While studies on ADHD and addiction exist, this specific approach of systematic data collection in a cohort is relatively novel.
