Filip Morys, a postdoctoral researcher in neuroscience at McGill University explains to LiveScience : “This is further proof that the major cardiovascular risk factor linked to obesity is linked to neurodegeneration.” Despite this, the brains of obese people are not at the same point as those with the disease. d’Alzheimer.
The analyzes cannot prove that obesity is the cause of the thinning of these neuronal areas. However previous research on mice genetically predisposed to develop Alzheimer’s and put on a diet rich in carbohydrates and lipids have proven that weight gain accelerates cognitive disorders and brain degeneration.
Researchers at McGill University believe that people who are obese or have a BMI between 25 to 25.9 (overweight), might slow cognitive decline if they can get closer to a healthier weight. But this is not certain and it will be necessary to undertake clinical studies to be sure. Because, as Dr. Heather Ferris, assistant professor at the University of Virginia (USA) concludes: “Although many effects of obesity are reversed with weight loss, once a neuron is dead, it is gone and [n’est] not replaced.“
