Statins lower the risk of developing Alzheimer's disease by limiting lipid raft endocytosis and decreasing the neuronal spread of Herpes simplex virus type 1.

Many possible risk factors for Alzheimer's disease (AD) have been investigated, with only a very few showing positive associations and none defining the etiology of the neurodegenerative disease. The presence of herpes simplex virus type 1 (HSV-1) DNA in the brain, coupled with apolipoprotein E allele e4 (ApoE e4), has been suggested to confer an increased risk for AD. Studies have shown that pathogens, including viruses, utilize clathrin-independent endocytosis, i.
