High cholesterol might be linked to Alzheimer's Disease

New research suggests that high cholesterol levels could boost the risk of Alzheimer's disease by creating more brain-clogging bits known as plaque. The finding doesn't directly prove that high cholesterol causes Alzheimer's disease or that lowering it would reduce the risk. Also, researchers didn't find any link between high cholesterol and tangles, which also clog the brain in those with Alzheimer's. Still, the findings add to previous research that has linked insulin resistance to Alzheimer's disease, said study author Dr. Kensuke Sasaki. Better control of both cholesterol levels and insulin resistance, both risk factors for heart disease, "might contribute to a strategy for the prevention of Alzheimer's disease," said Sasaki, an assistant professor of neuropathology at Kyushu University in Japan
