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.

Primary | Brief assessment of cognitive impairment | Cognitive impairment assessed with help of MMSE(Mini-mental State Examination).The MMSE has 5 scaled scores; the scores are weighted sums of the questions in each section. The 5 sections and their range of score are listed below:Orientation 0-10;Registration 0-3;Attention and calculation 0-5;Recall 0-3;Language 0-9.Total score range from 0-30. Lower scores = more disability, higher scores = less disability. | 1.5 h before fMRI examination | |
Primary | Resting-state functional magnetic resonance imaging results | 3D T1-weighted magnetization parameters: TR/TE/flip angle = 7.2 ms/min full/8; FOV = 256 mm; 312 slices; slice thickness = 1 mm.
For the BOLD sequence, a series of 35 interleaved transversal slices were acquired for full-brain coverage with a gradient-echo based, echo planar imaging (EPI) sequence with the following parameters: TR/TE/ flip angle = 2000 ms/30 ms/90; FOV = 224 mm; slice thickness = 4.0 mm. |
Up to 1 month after ICU discharge(It was judged by the doctor in charge according to the patient's recovery) | |
Primary | Blood inflammatory markers | 2-4 ml of blood was drawn for blood inflammatory markers(IL-1ß,IL-2R,IL-6,IL-8,TNF-a) detection. | 2h before taking fMRI examination | |
Secondary | Blood markers | 2-4 ml of blood was drawn for blood markers(NSE) detection. | the same day with fMRI examination(2h before taking fMRI examination) | |
Secondary | Assessment of cognitive impairment | Cognitive impairment assessed with help of MoCA(Montreal Cognitive Assessment).Total score range from 0-30. Lower scores = more disability, higher scores = less disability. | 1.5h before taking fMRI examination | |
Secondary | Specific assessment of cognitive impairment 1 | Cognitive impairment assessed with help of DS(digit span test),including DST-F(Forward digit span test) and DST-B(backward digit span test).Total score range from 5-20. Lower scores = more disability, higher scores = less disability. | 1.5h before taking fMRI examination | |
Secondary | Specific assessment of cognitive impairment 2 | Cognitive impairment assessed with help of AVLT(auditory verbal learning test),Total score range from 0-12. Lower scores = more disability, higher scores = less disability. | 1.5h before taking fMRI examination | |
Secondary | Specific assessment of cognitive impairment 3 | Cognitive impairment assessed with help of CFT(complex figure test),Total score range from 0-36. Lower scores = more disability, higher scores = less disability. | 1.5h before taking fMRI examination | |
Secondary | Specific assessment of cognitive impairment 4 | Cognitive impairment assessed with help of SDMT(symbol digit modalities test),Total score range from 0-105. Lower scores = more disability, higher scores = less disability. | 1.5h before taking fMRI examination | |
Secondary | Specific assessment of cognitive impairment 5 | Cognitive impairment assessed with help of VFT(verbal fluency test),The total score was the number of animals named in one minute. Lower scores = more disability, higher scores = less disability. | 1.5h before taking fMRI examination | |
Secondary | Specific assessment of cognitive impairment 6 | Cognitive impairment assessed with help of CDT(clock drawing test),Total score range from 0-4. Lower scores = more disability, higher scores = less disability. | 1.5h before taking fMRI examination | |
Secondary | Specific assessment of cognitive impairment 7 | Cognitive impairment assessed with help of TMT-A(trail making test part A) and TMT-B(trail making test part B), the test outcome was the time to complete the test(seconds). Longer time = more disability, Shorter time = less disability. | 1.5h before taking fMRI examination | |
Secondary | Assessment of Depression | SDS(self-rating depression scale) was used to assess the depression status of the participants in the past week.The SDS has 20 questions; each question was scored on a scale of 1-4;total score range from 20-80;the standard score(total score multiplied by 1.25):less than 53 was normal group,53-62 was mild depression, 63-72 was moderate depression, more than 72 was severe depression. | 1.5h before taking fMRI examination |
