For a better understanding of Alzheimers, researchers are taking a look at liver

Alzheimer's disease is the most common form of dementia, affecting approximately 50 million people worldwide. In the race to gain a better understanding of the drivers behind Alzheimer's disease, one research team looks to the link between the brain, the gut, and the liver. The researchers decided to start taking liver function into account — in the context of Alzheimer's disease — because of the organ's role in the body's metabolic processes. In this study, blood biomarkers, reflecting liver function, were related to brain imaging and [cerebrospinal fluid] markers associated with Alzheimer's. No stone can be left unturned in our attempt to understand the disease and to identify viable therapeutic targets.", says Andrew Saykin. In the future, the current findings plus other related investigations may help perfect a more personalized approach to treating Alzheimer's, as precision medicine keeps on gaining ground.

Is dementia linked to anaemia?

A recent study has concluded that people with both higher-than-normal and lower-than-normal levels of haemoglobin have a higher risk of developing dementia as they age. Anaemia is one of the most common blood disorders; worldwide, it affects an estimated 1.62 billion people. Low haemoglobin levels are linked to a number of adverse health outcomes, including stroke and coronary heart disease. However, there is little information regarding how haemoglobin levels might relate to the risk of dementia. During an analysis, the scientists accounted for a range of variables that might skew the results. These included age, sex, smoking, alcohol consumption, body mass index (BMI), diabetes, kidney function, and cholesterol levels. The scientists found that people with high and low haemoglobin levels had an increased risk of dementia compared with individuals with mid-range levels. The authors write: "Compared [with] no anaemia, the presence of anaemia was associated with a 34% increase in the risk of all cause dementia, and [a] 41% increase for [Alzheimer's disease]."
