According to two special studies recently published in the American scientific monthly Journal of Clinical Investment, the disease Alzheimer's may well be related to insulin resistance, which means that this disease can be attributed to the so-called third type of diabetes. As part of the research, scientists monitored the increased risk of developing Alzheimer's disease in patients with diabetes. It is reported that in the brain tissues of people suffering from Alzheimer's disease, reduced nerve activity was found, which led to impaired insulin production by the pancreas.
However, according to some experts, despite intriguing research results, scientists have failed to prove that insulin deficiency in the brain can be caused by Alzheimer's disease. In addition, there is no evidence that insulin resistance can affect patients' cognitive abilities, impairing them. Be that as it may, there is a link between insulin resistance and Alzheimer's disease, as this is confirmed by the results of two independently conducted studies. The first study was led by Konrad Talbot, Steve Arnold, and others from the University of Pennsylvania in the United States. Another study was conducted by Brazilian scientists from the University of Rio de Janeiro (Rio de Janeiro). It was led by Fernanda De Felice, Sergio Ferreria and other Brazilian specialists.
A team of researchers from the University of Pennsylvania studied insulin levels in the brain tissues of deceased people by performing post-mortem autopsies. As a result, scientists have concluded that the activity of the brain's nerve endings responsible for controlling insulin production is directly related to memory and cognitive function. The researchers also suggested that insulin resistivity is a very common phenomenon characterizing the early stage of Alzheimer's disease. At the same time, a team of Brazilian scientists found disorders related to signals that control insulin production in the brain tissues of rodents and some other experimental animals that performed in research as research models. Brazilians have also been able to demonstrate that the use of modern anti-diabetic drugs normalizes the functioning of nerve endings and the transmission of signals that control insulin production. This, in turn, significantly improves cognitive function in the brain. In the end, both of these studies were, according to most members of the scientific world, solid evidence that insulin resistance is linked to Alzheimer's disease. This, in turn, opens up new ways to develop therapeutic methods for the treatment of the latter disease.
