Roy: It is my guess that EMF does not directly affect neurons. We have two complementary hypothesis - one published in our 1996 hypothesis paper in Neurology which you have from the San Antonio meeting - and one related to melatonin down-regulation. We hypothesized that EMF exposure may cause increased production of amyloid beta peripherally, e.g., by skin cells, which then migrates to the brain and over the years accumulates sufficiently to aggregate and become neurotoxic, etc. etc. As you are well aware, melatonin production can apparently be decreased by EMF exposure. Melatonin is apparently capable of reducing oxidative damage to neurons and inhibiting the neurotoxicity of amyloid beta - in laboratory cellular studies. Thus, EMF exposure may concurrently product 2 affects leading to Alzheimer's disease initiation and progression. Once the process is started in the brain, it is self-perpetuating. We think that decades of EMF exposure are likely required. We have submitted a proposal to a funding governmental agency to partiallly test these theories by investigating amyloid beta and melatonin production in workers in specific occupations. We shall see what happens. Gene Sobel I hope all is well with you.
