Summary

What Researchers Did

Researchers longitudinally tracked neuroimaging and neuropsychological changes in a young woman following carbon monoxide poisoning.

What They Found

The patient experienced memory impairment, indicated by a low Delayed Recall Index score, and a 3% decrease in hippocampal volume 320 days after CO poisoning. Her memory function improved by 530 days, coinciding with an approximately 7% increase in hippocampal volume during that period.

Canadian Relevance
