The present article aims to describe a case-study about an elementary school pupil showing high mathematics learning difficulties and previously diagnosed with Conduct Disorder (CD) associated to Attention Deficit/Hyperactivity Disorder (ADHD). Initially an operational description of the case was devised, as well as the relation between CD/ADHD and mathematics learning. The case study involved interviews, documental analysis, classroom observations, and interaction with the pupil in pedagogical contexts. Data showed that CD/ADHD did not produced the suggested math learning difficulties, although such association, along with parental and school factors, tended to aggravate the case development. Specific directions and suggestions in order to reorganize the school actions on the case are presented.
