Abstract: Objective To investigate the effects of carbon monoxide poisoning on the long-term cognition in elderly patients.Methods Totally 53 patients with carbon monoxide poisoning and 51 healthy persons at our Hospital from June 2005 to June 2008 were enrolled.Mini-mental state examination(MMSE) and activities of daily living(ADL) scale were utilized to evaluale the life quality of the elderly patients through a cross-sectional study on July 2011.Results MMSE score showed that the attention calculation score,delayed recall score,and total score were higher in control group (4.9±0.4,2.9±1.0,28.3±2.3,respectively) than in carbon monoxide poisoning group (4.5±0.8,2.6±0.6,25.5±3.5,respectively) (t＝3.138,3.607,4.802,all P＜0.05).ADL score of carbon monoxide poisoning group was 26.7±7.3,and that of the control group was 2.04±7.6 (t＝1.827,P＞0.05).Conclusions Elderly patients with acute carbon monoxide poisoning may cause long-term cognitive impairment with decreasing attention calculation and delayed recall.
