Summary

What Researchers Did

Researchers reported a case of delayed leukoencephalopathy after carbon monoxide poisoning in an elderly woman and reviewed relevant literature.

What They Found

They found that a 65-year-old woman developed subacute dementia, abnormal behavior, and gait disturbance after carbon monoxide poisoning. Her condition, initially improving, worsened within one month, leading to drowsiness, poor responsiveness, limb chorea, and urinary incontinence. The review suggested that subacute dementia from CO poisoning in patients over sixty years old recovers late, often after a year or more.
