There should be a type 3 diabetes (Alzheimer’s) section in the health category of the forum.
From the article:
For the first time a “tipping point” molecular link between the blood sugar glucose and Alzheimer’s disease has been established by scientists, who have shown that excess glucose damages a vital enzyme involved with inflammation response to the early stages of Alzheimer’s.
Abnormally high blood sugar levels, or hyperglycaemia, is well-known as a characteristic of diabetes and obesity, but its link to Alzheimer’s disease is less familiar.
Diabetes patients have an increased risk of developing Alzheimer’s disease compared to healthy individuals. In Alzheimer’s disease abnormal proteins aggregate to form plaques and tangles in the brain which progressively damage the brain and lead to severe cognitive decline.
By studying brain samples from people with and without Alzheimer’s using a sensitive technique to detect glycation, the team discovered that in the early stages of Alzheimer’s glycation damages an enzyme called MIF (macrophage migration inhibitory factor) which plays a role in immune response and insulin regulation.
MIF is involved in the response of brain cells called glia to the build-up of abnormal proteins in the brain during Alzheimer’s disease, and the researchers believe that inhibition and reduction of MIF activity caused by glycation could be the ‘tipping point’ in disease progression. It appears that as Alzheimer’s progresses, glycation of these enzymes increases.
Dr Omar Kassaar, from the University of Bath, added: “Excess sugar is well known to be bad for us when it comes to diabetes and obesity, but this potential link with Alzheimer’s disease is yet another reason that we should be controlling our sugar intake in our diets.”
