ABSTRACT
Several studies have researched the attentional functioning of schizophrenic patients by means of the Attentional Network Test. The present work reviews these studies and assesses the clinical relevance of their results. Both the reviewed data and our own results suggest that the Attentional Network Test does not provide a clear-cut discrimination of the attentional profile of schizophrenic patients from a clinical point of view. However, after classifying patients according to their psychotic symptoms, it became evident that positive syndrome patients are less efficient at tasks that tap the orientation network.

Varios estudios han investigado el sistema atencional de pacientes esquizofrénicos usando el test de las redes atencionales. En este trabajo se revisan estos estudios y se evalúa la relevancia clínica de sus resultados. Los resultados de la revisión y del presente trabajo sugieren que el test de las redes atencionales no discrimina claramente el perfil atencional de los pacientes esquizofrénicos desde un punto de vista clínico. No obstante, tras subdividir a los pacientes en función de su sintomatología psicótica se evidenció que los pacientes con síndrome positivo mostraron una menor eficiencia en la red de orientación (AU)
