Prevalence and factors associated with the presence of non alcoholic fatty liver disease in an apparently healthy adult population in primary care units.

Background: Fatty liver disease is characterized by the accumulation of fat vacuoles inside of the hepatocytes. Non alcoholic fatty liver is associated with obesity, type 2 diabetes, dyslipemia, the intake of certain drugs and with the so-called metabolic syndrome.

From a pathophysiologic point of view, the authors discuss the role of the frontal, near the limbic area, localization of the plaques.
