Carbon monoxide poisoning: neurologic and psychiatric sequelae

Poisoning with carbon monoxide is a frequent means of suicide1 and has an estimated mortality of 30% . However, there have been few case reports of neuropsychiatric sequelae in survivors. We report the case of a young woman with parietal lobe signs 6 months after she had attempted suicide with a combination of barbiturate overdose and carbon monoxide poisoning. The purpose of this report is to call attention to these signs, which may be mistaken for signs of a psychiatric disorder, and to discuss the importance of the barbiturate overdose in this case.
