Summary

Long-term cognitive dysfunction greatly influences patient's quality of life after critical illness. However,its neurophysiological basis remains unknown.This is a 3 year fMRI study conducted at the Jiangyin people's Hospital. This study utilize resting-state functional magnetic resonance imaging(fMRI) to investigate the regional alterations in survivors with cognitive impairment.Further, the investigators hypothesize that these regional changes in fMRI activity are predictive of cognitive impairment.

Detailed description

Critically ill patients who had hospitalized in ICU at least 2 days and who consented to participate will take the examination of brain fMRI,blood inflammatory markers and cognitive assessment after ICU discharge. Individuals of healthy control group are recruited from the community will be made to match them on age,sex and education to individuals recruited for groups of ICU Survivors.Those healthy people will also take the examination of brain fMRI,blood inflammatory markers and cognitive assessment.
