Abulia is defined as a decrease in spontaneous speech and activity with increased response latency and decreased persistence with a task. When considering post-operative deficits according to anatomic location relative to the corpus callosum, an increased frequency was noted for posterior butterfly gliomas of the splenium (7/19, 47%), while every medial butterfly glioma of the body of the corpus callosum resulted in . There is no generally accepted treatment, and it is not known if late treatments are effective. This is termed 'abulia': 'the specific neurological syndrome comprising slowness, decreased responsiveness, apathy, etc.' (Fisher [1983], p. 9). Anterior cerebral artery strokes occur in the territory of the anterior cerebral artery which involves the superior and medial part of the parietal lobe along with the midline of the frontal lobe.
