akinetic mutism
Pronunciation: ay-ki-NET-ik MYOO-tizm
A neurological syndrome characterized by profound apathy and lack of voluntary movement or speech despite apparent wakefulness.
Full Definition
Akinetic mutism is a rare neurological condition in which patients appear awake and alert but demonstrate profound apathy, with markedly reduced or absent voluntary movement and speech. The condition typically results from bilateral damage to the anterior cingulate cortex or related limbic structures. Patients may track objects with their eyes and show basic reflexes, but they initiate no purposeful behavior and do not respond to commands or questions. This distinguishes it from catatonia or vegetative states, as the level of consciousness appears preserved.
Usage
Usage note: Often confused with catatonia; emphasize the preservation of apparent consciousness in akinetic mutism.
