ment et qualitativement (méta-analyse de Robinson et al.) [17]. Selon les études, les auteurs retrouvent des diffi cultés au niveau de l’apprentissage, de la mémoire verbale, de la mémoire visuelle, de la mémoire de travail, de l’attention soutenue, de la vitesse de traitement de l’information, des fonctions exécutives. En revanche, ne sont habituellement pas retrouvés de défi cits de l’intelligence générale (QI), des fonctions motrices, de l’attention sélective, ni du langage. L’une des raisons à l’hétérogénéité des résultats tient à la diffi culté d’explorer la cognition dans le trouble bipolaire. De nombreux facteurs doivent être pris en compte, comme la présence de symptômes thymiques résiduels, l’histoire longitudinale du trouble (âge de début, nombre d’épisodes en raison, entre autres, de l’impact neurotoxique des épisodes dépressifs et des effets cognitifs délétères des durées d’hospitalisation), le niveau de sévérité du handicap, les comorbidités (en particulier addictives), les troubles de personnalité, les traitements pris (du fait de l’impact cognitif de psychotropes comme les benzodiazépines), le type de trouble bipolaire I ou II. Enfi n, l’infl uence de la symptomatologie psychotique (ici assimilée à l’existence de symptômes positifs : délire et hallucinations) est importante, et on sait qu’environ la moitié des patients bipolaires de type I font l’expérience de symptômes psychotiques au cours de leur existence. Cette infl uence peut être explorée lors des épisodes thymiques aigus ou en période euthymique. Psychose, troubles bipolaires et cognition
