Resumen

Varias líneas de investigación actual sugieren que en el trastorno bipolar (TBP) hay una disfunción de la corteza prefrontal (CPF) dorsal y ventral. Usamos imágenes de resonancia magnética funcional para comparar los patrones de activación cerebral en pacientes derivados a consulta por TBP y en los controles, mientras desempeñaban tareas seleccionadas por su especificidad relativa en la participación de la CPF dorsal (tarea de memoria de trabajo de recuerdo de una serie de n letras a la inversa) o ventral (tarea de juegos de azar). Siete pacientes con TBP fueron seleccionados entre los participantes en el Proyecto del Trastorno Bipolar de Maudsley en función de remisión clínica, ausencia de déficit cognitivos y monoterapia con estabilizadores del estado de ánimo. Individualmente, los sujetos se agruparon por sexo, edad y CI con un número similar de controles sanos. En la tarea de serie inversa de n letras sólo se encontraron diferencias entre los grupos en respuesta al aumento de carga de memoria. Los pacientes no mostraron la respuesta dinámica prevista en la CPF dorsal, sino que tuvieron más activación en las cortezas parietales. Durante la tarea de juegos de azar, los controles exhibieron una activación importante en la CPF ventral y dorsal; ésta se atenuó en pacientes con TBP donde hubo un aumento de la activación de las regiones laterotemporal y lateropolar. Nuestros resultados sugieren que hay anormalidades de rasgo en las funciones de la CPF dorsal y ventral en pacientes con TBP que pueden ser más pronunciadas durante las tareas que se basan en la interacción de la CPF dorso-ventral.
