Alzheimer’s disease (AD) is a senile or presenile demen-
tia and it is probably caused by the deposit of -amyloid
plaques disrupting the myelin layer of the axons, the fun-
damental structure of the neuronal signal propagation in
the neuronal system. However, the true causes are still not
understood. The main symptoms of AD include impaired
cognitive behaviour, loss of short term and long term mem-
ory, disorientation, loss of language abilities, personality
changes, deterioration of the immune system and eventual
death. AD particularly reflects itself in terms of the small-
world network characteristics of the brain, as described in
Section 3. Compared to the healthy brain, the Alzheimer af-
fected brain, shown by electroencephalogram (EEG) record-
ings in [9], reveals reduced connections between different
functional areas of the brain, smaller clustering coefficients
and longer characteristic path-length. Existing therapies
can prolong the average life expectation and are currently
based on heavy pharmacological treatments. Medical re-
search has been spending much efforts in finding final ther-
apies. Recent experiment reported in [2] have shown that
exposure to the EM field generated by CDMA mobile phones
has potential benefits against the development of Alzheimer’s
disease. Through experiments done on transgenic Alzheimer
mice, improved cognitive behaviours were observed after
long term exposure (8 months). The employed RF radia-
tion was operating at 918 MHz, over a 2 hours per 24 hours
cycle, with whole body specific absorption rate (SAR) of
0.25 W/kg ± 2 dB, which is equivalent to head transmission
for standard cell phone use in humans. These preliminary
results point to possible treatment of AD with the aid of RF
exposure. To this end, it is fundamental to define the basis
of a suitable model of the parameters governing EM expo-
sure and effects they induce on the brain in a way similar to
