Abstract: We propose to patent the treatment of Alzheimer's disease and other neurodegenerative diseases in the central nervous system using the external application of ultra-low-intensity oscillating magnetic fields in the gamma frequency band that will stimulate neuron currents and activate the natural healing processes of microglia. Observed magnetoencephalographic emissions are thought to be generated by neuron-cluster current loops producing equivalent current dipoles (ECDs). Our analysis of these ECDs concludes that adequate neuron stimulation will require a field threshold above a pico-Tesla. Some experimental testing will be required to ascertain the threshold for effective microglial activation. Our invention is human headgear containing a set of orthogonal current coils for magnetic stimulation of neurons to activate brain microglia. Other coil configurations may be useful for ganglia activation elsewhere in the body.
