The term akinetic mutism was coined by Cairns to describe a patient with an epidermoid cyst of the third ventricle, who was mute and immobile, but followed with her eyes the observer as well as moving objects and who could be brought by repetitive stimulation to ‘whisper few onosyllables’ and ‘slow feeble voluntary movements’, in the absence of ‘gross alterations of sensory–motor mechanisms operating at a more peripheral level’. Akinetic mutism (a.m.) represents an extreme form of abulia (abulia major) due to disruption of reticulothalamofrontal and extrathalamic reticulo-frontal afferents. Two forms of a.m. have been identified. The first variety of a.m. has been described in patients with bilateral occlusion of the anterior cerebral arteries and hemorrhages (with vasospasm) from anterior communicating aneurysms. |
