(a) deploying at least two electrodes spaced apart on. the skin of the patient (b) detecting and recording a bioelectrical signal in and around said electrodes,, the bioelectrical signal being a stochastic signal (c) transforming the stochastic signal into a voltage versus frequency spectra using a Fast Fourier Transform (FFT) algorithm (d) comparing a graph of a resultant EFT level of the patient to at least one graph of a baseline ITT level and (e) determining a presents of a non- visible (occult) malady based on said comparison. Methods for monitoring a treatment regimen for non-visible (occult) maladies and for modulating the amplitude of endogenous bioelectrical stochastic signals in. a human patient are also disclosed.
