What Researchers Did
Researchers reported the case of a five-year-old boy who developed delayed neuropsychiatric syndrome following carbon monoxide poisoning.
What They Found
A five-year-old boy initially recovered from carbon monoxide (CO) poisoning after hyperbaric oxygen (HBO) therapy, but developed lethargy, visual and gait disturbances two days later, followed by left hemiparesis and mood lability. MRI revealed high signal-intensity lesions in the hippocampus and cerebral cortex initially, with globus pallidum lesions at 14 days and cortical laminar necrosis at 4 months. While neurological symptoms gradually subsided during 10 days of HBO, left-hand paresis, quadrantic hemianopsia, impaired attention, slow mental processing, and incontinence persisted.
Canadian Relevance
This study has no direct Canadian connection as it reports a case from Japan.
Study Limitations
As a single case report, the findings of this study may not be generalizable to all children experiencing delayed neuropsychiatric syndrome after carbon monoxide poisoning.
