Fatty Liver Disease May Increase Dementia Risk

Nonalcoholic fatty liver disease (NAFLD) is a metabolic disorder that affects about 25% of the general population. This condition is associated with a number of vascular complications, including cardiovascular problems. However, NAFLD may also increase the risk of dementia. There is a need to investigate this association. Some researchers speculate that inflammation is one of the factors underlying the increased risk of dementia in patients with NAFLD.

NAFLD causes liver damage, and it is known to induce signs of Alzheimer’s disease in wild-type mice. In addition, it has been found to accelerate the pathological signs of Alzheimer’s disease in an AD model. However, this has not been clearly shown in humans. Although some studies have suggested that neuroinflammation is a key factor in the association between NAFLD and dementia, further research is needed to determine whether inflammation plays a role in the relationship.

Dementia is characterized by cognitive deficits and memory loss. It is associated with systemic inflammation and metabolic comorbidities. Metabolic comorbidities include hyperlipidemia, hypertension, and diabetes. Similarly, metabolic comorbidities in patients with NAFLD have been identified as an important component in the association between this disorder and dementia.

To determine whether there is an association between NAFLD and dementia, we searched PubMed and the Web of Science for published articles. We selected studies that examined the relationship between NAFLD and dementia, as well as studies that studied brain function in middle-aged and elderly people. Our search strategy included keywords such as inflammatory, dementia, and nonalcoholic fatty liver disease. The results of our searches showed that NAFLD was associated with a higher risk of dementia in both cross-sectional and retrospective studies.

Several risk factors for NAFLD, including obesity, insulin resistance, and steatorrhea, are known to have a negative impact on brain function. A recent study showed that patients with NAFLD had four times the risk of developing cognitive dysfunctions as compared to healthy controls. While further studies should further examine this association, it is also possible that a variety of other risk factors play a role.

In a recent study, Zelber-Sagi S and colleagues analyzed the relationship between NAFLD and brain volume. Researchers used a mouse model to study the effect of NAFLD on brain volume. They fed the mice two different diets. One contained 10% fat, while the other had 55% fat. Both diets were similar to each other in terms of total energy intake, but the latter was more concentrated in fat. By feeding the mice these two different diets, scientists were able to determine if fat accumulation in the liver could lead to a decline in brain volume.

Other studies suggest that liver inflammation and systemic inflammatory diseases can contribute to the progression of NAFLD. An increase in inflammation can lead to liver fibrosis and cirrhosis, and these diseases have been known to be severe. Moreover, excessive production of proinflammatory cytokines by macrophages is believed to be a key contributor to the onset and development of NAFLD.
