The objective of this study is to contribute to the establishment of a memory profile in subjects with attention deficit disorder with hyperactivity (ADHD). We examined fifty-one adolescents: 16 ADHD and 35 controls, aged between 14 and 16. Neuropsychological exploration included tests of short-term memory and of declarative and implicit (incidental and procedural) memory. Subjects with ADHD presented deficits in their mnesic abilities. These deficits do not involve all type of memory, but are selective. Declarative memory and, especially, short-term memory show higher deficits than implicit or non-declarative memory: incidental learning is preserved and procedural learning is similar to that obtained by control subjects, although this forn of learning presents more diflculties for ADHD subjects learning with a higher difficulty
