The Importance of Adipokines in Alzheimer's Disease

Dementia and Alzheimers disease are characterized by disturbances in brain function and structure. Similarly, body mass index and obesity are associated with certain brain pathologies, including Alzheimers disease and dementia. In fact, there is mounting evidence linking metabolic dysfunction with dementia and Alzheimers disease. Major endocrine axes constitute links between brain and peripheral tissues, especially adipose tissue. Adipose tissue is metabolically very active and produces a variety of adipokines known to affect both peripheral and central nervous system processes. Experimental studies suggest that changes in adipokine function may contribute to the pathogenesis of Alzheimers disease. Herein, we review the adipokines leptin and adiponectin which are associated with morbidities related to obesity as well as dementia and Alzheimers disease. [Dis Mol Med 2015; 3(2.000): 22-28
