On a frontal symptom “adhesion to a single standard or set”
—11 years follow up study on a patient with prefrontal infarction—

Abstract

    The course and symptoms in 11 years of a patient with left prefrontal infarction are described. Early symptoms or complaints are thought to be a manifestations of the disorder of working memory. However, recent symptoms or complaints are not interpretable as the disorder of working memory, but may closely relate to a frontal symptom “adhesion to a single standard or set” including the difficulty of the change of set and the difficulty of the organization of multiple information.
