What Researchers Did
This case report describes a 52-year-old woman who developed severe brain and mental symptoms one week after acute carbon monoxide poisoning, and how her condition improved after treatment with the medication ziprasidone.
What They Found
The patient initially received hyperbaric oxygen therapy for acute carbon monoxide poisoning and later daily hyperbaric oxygen therapy during hospitalization, along with several other medications. Despite these treatments, she continued to suffer from severe neuropsychiatric symptoms, including movement disorders, cognitive decline, and disorientation. After 10 days of treatment with ziprasidone (80 mg/day), her mental condition, cognitive function, and ability to perform daily activities showed substantial improvement.
Canadian Relevance
This study was not conducted by Canadian authors or in Canada. However, carbon monoxide poisoning is a Health Canada-recognised indication for hyperbaric oxygen therapy, and this study addresses a serious complication of this condition.
Study Limitations
As a single case report, these findings cannot be broadly applied to all patients with delayed carbon monoxide encephalopathy.
