What Researchers Did
Researchers presented a case report of a 37-year-old woman with long-term neuropsychiatric symptoms after carbon monoxide poisoning and reviewed existing literature on the topic from 1974 to 2006.
What They Found
The literature review found that almost all patients reported subjective symptoms for over 30 years post-carbon monoxide intoxication (COI). More than 50% of patients experienced cognitive impairments and neurological symptoms, while nearly 75% developed affective disorders and over 50% had personality disorders years after COI.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a case report and literature review, the findings may not be broadly generalizable and are dependent on the quality and heterogeneity of the reviewed literature.
