Different types of writing disorders associated with brain pathology have been described. Limited mention the writing disturbances associated with prefrontal pathology, however, is found. Clinical observations of patients not only with focal prefrontal pathology but also with other conditions affecting the frontal system (e.g., traumatic head injury, dementia) confirm the assumption that these patients present an overt decrease in the ability to express ideas in writing. ⋯ The term dysexecutive agraphia is proposed to refer to this writing disorder. Three illustrative cases are presented. It is finally suggested that questions regarding the ability to write should be included in dementia questionnaires and executive functioning testing.
