A study published in JAMA Neurology on August 11, 2014, suggests that minimizing apoE gene levels in the brain may be an approach to developing a treatment for Alzheimer’s disease. In the study, researchers found that a man with no apolipoprotein E, or apoE, in his body was cognitively normal and showed no neurological signs of Alzheimer’s. Those with a mutation of the gene called apoE4 have a higher risk of developing Alzheimer’s. You can read the study here.
