Cognitive Impairment, Non-Alcoholic Fatty Liver Disease
Conditions
Keywords
MRI, cognitive function
Brief summary
The purpose of this study is to explore the relationship between Non-alcoholic fatty liver disease and cognitive impairment and evaluate the effect of metabolic surgery or lifestyle intervention on cognition.
Detailed description
Previous research has shown that Non-alcoholic fatty liver disease (NAFLD) is associated with an increased risk of cognitive impairment. Even though there are many noninvasive tests available, a liver biopsy is still required for the accurate diagnosis of NAFLD. However, there are now few studies on cognitive function in patients with NAFLD based on pathological diagnosis. On one hand, in the cross-sectional study, biometric measurements, cognitive assessment, magnetic resonance imaging (MRI) results are analysed to explore the differences among control subjects and NAFLD patients undergoing liver biopsy. One the other hand, in the longitudinal study, changes in cognitive scales and MRI results in NAFLD patients both at baseline and 12-48 months after intervention are collected to investigate whether surgical intervention and weight control benefit brain function.
Interventions
RADIATIONCognitive assessment, functional magnetic resonance imaging
Our study investigated cognitive function, MRI measures of brain structure and activation in patients undergoing liver biopsy. We aimed to evaluate the changes of cognition during the process of NAFLD and explore the association between brain alterations and cognition.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| brain activation in fMRI | 1 day | All patients underwent odor-induced task fMRI on a 3.0T MR scanner with 222 volumes for task fMRI and 230 volumes for resting-state and functional fMRI. The odor-induced task consisted of fresh air rest and scent. Odor-induced brain activation was assessed by a general linear model using Statistical Parametric Mapping 12 (SPM12) software. Following extraction of the three separate conditions fresh air, scent, and rest from the whole sequence, contrasts were made for each participant between fresh air \> rest and scent \> rest. Odor-induced fMRI data were analyzed in the mask of the olfactory network, including the regions of bilateral parahippocampus, amygdala, piriform cortex, insula, orbitofrontal cortex, hippocampus, and entorhinal cortices. |
| Participants' personal information | 1 day | Self-reported information (age in years, gender, education in years) |
| Physical assessments. | 1 day | BMI (body mass index) in kg/m\^2 |
| Cognitive Assessment (MMSE) | 1 day | Mini-Mental State Examination (MMSE) scores from 0-30, and the test means better cognition with a higher score. |
| Cognitive Assessment (MoCA) | 1 day | he Montreal Cognitive Assessment (MoCA) scores from 0-30, and the test means better cognition with a higher score. |
| Cognitive Assessment (RBANS) | 1 day | The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) scores from 0-800, and the test means better cognition with a higher score. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of Cognitive Assessment (MMSE) from baseline | 12-48 months | Whether Mini-Mental State Examination (MMSE, scores from 0-30) changes during follow-up, and the test means better cognition with a higher score. |
| Change of Cognitive Assessment (MoCA) from baseline | 12-48 months | Whether the Montreal Cognitive Assessment (MoCA, scores from 0-30) change during follow-up, and the test means better cognition with a higher score. |
| Change of Cognitive Assessment (RBANS) from baseline | 12-48 months | Whether the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS, scores from 0-800) changes during follow-up, and the test means better cognition with a higher score. |
| Change of brain MRI measurement from baseline | 12-48 months | whether brain activation changes during follow-up |
| Change of weight from baseline | 12-48 months | whether body weight (kg) changes during follow-up |
