Obesity increases risk of age-related cognitive decline and is accompanied by peripheral inflammation. Studies in rodent models of obesity have demonstrated that impaired hippocampal function correlates with microglial activation, however, the possibility that neuron/microglia interactions might be perturbed in obesity has never been directly examined.  Now, a study from researchers at Augusta University has shown that when a high-fat diet causes a person to become … Continue reading Study shows obesity causes microglia to start eating neural connections.
