In a study on animal models, lead researcher Suzanne de la Monte, MD, MPH, of Rhode Island Hospital, utilized chronic high fatty diets to cause a two-fold increment in hateful body weight unit. In these animal models, there was a marginally reduced mean brain weight and a significantly reduced mean brain weight/body weight ratio, providing evidence that obesity with T2DM is sufficient to cause mild global atrophy in the brain.
De la Monte says, "In nub, the psyche shrinks and several biochemical and molecular abnormalities establish in patients with AD, including brain insulin resistivity, develop with chronic fleshiness and T2DM. However, the extent of the abnormalities in no way matches AD." Researchers note that the neuropathological abnormalities were mild and the associated brain insulin resistance could serve as a co-factor in the development and progression of AD.
Overall, the study establish that that the personal effects of corpulency and T2DM can fundamentally aggravate or contribute to the severity or patterned advance of AD, but cannot be the sole suit of the condition. The findings suggest that strategies to deoxidise obesity and prevent or control T2DM could modify the clinical course of mild cognitive impairment and AD.
De la Monte likewise notes, "We don't know yet if these personal effects of T2DM/obesity are reversible with free weight loss. However, we're fair sure that the abnormalities are related to to the T2DM that accompanies obesity and not just increased weight."
