POSIBLES RELACIONES ENTRE ENFERMEDAD DE ALZHEIMER, INSULINORRESISTENCIA Y DIABETES MELLITUS TIPO 2

Alzheimer’s Disease (AD) is the most common cause of dementia. There are multiple risk factors associated with the disease, including type 2 diabetes mellitus. In recent years a growing body of evidence involves insulin resistance as cause and consequence of the development of brain lesions typical of AD. Currently the diagnosis of AD is based on clinical neuropsychiatric criteria and postmortem histopathological confirmation; however, major advances in genetic testing, biochemical markers and functional neuroimaging will increase diagnostic accuracy. The association of alterations in the signaling pathway of insulin with the AE has given rise to the interest of evaluating agents originally developed for the treatment of type 2 diabetes as potential therapies. Numerous investigations are undoubtedly still needed to consolidate the findings found so far.
