What's akinetic mutism?
Akinetic mutism is a variety of stupor in which the patient is unable to talk or carry out purposeful behaviour but may lie with eyes open, seemingly unaware of what is going on around him. It results from bilateral damage to the orbital surface of the frontal lobes. The patient appears awake and has normal ocular movement but does not speak, is incontinent, and has minimal motor response to painful stimulation. Akinetic mutism is a state in which a person is unspeaking (mute) and unmoving (akinetic). A textbook on clinical neurology observes that a person with akinetic mutism has "sleep-waking cycles but, when apparently awake, with eyes open, lies mute. immobile and unresponsive." Akinetic mutism is often due to damage to the frontal lobes of the brain. |
