Multiple cognitive disturbances are typical of bipolar disorder (BD), between them of memory. The memory deficits in the different phases, including euthymia, of adult patients they are well studied, whereas in children and adolescent diagnosed with BD the study of memory is an area of recent interest. A review of studies on the performance in memory in pediatric BD show that this capacity is specially affected and that the studies in phases of euthymia of the pediatric BD are scanty. This way, the aim of the present work is to study the principal alterations of memory, in the euthymic phase, of two cases of adolescent bipolar disorder. The obtained results point at a widespread deficit of the studied capacities of memory, being more marked in visual delayed memory, visual working memory and immediate and delayed recall of verbal material This information is consistent with the literature and shows that memory as a variable of importance in bipolar patients of early ages, being desirable studies with major statistical power to obtain a profile of performance and others that delimit the role of this capacity in the disorder.
