[Gesture apraxia disclosing carbon monoxide poisoning].

A seventy year old right handed woman presented progressive limb apraxia and headache due to carbon monoxide poisoning. Thereafter, when in hospital for one week, she developed akinetic mutism, coma and died. Limb apraxia has been rather uncommonly reported in carbon monoxide poisoning. The akinetic mutism observed after the patient had been removed from intoxication could be analysed as a delayed encephalopathy related to a chronic carbon monoxide poisoning.
