NEUROSTIMILUATION TO REDUCE EFFECTS OF CHRONIC CLUSTER
HEADACHES

The effects of neurostimulation have been demonstrated
in various experiments and described in many academic
journals. Documentation relating to stimulation of the brain
and nerves by an artificial electronic device will be
used on how exactly the electric pulses affect the senses. The
device’s manufacturer, Autonomic Technologies Inc., will
provide the device’s design and technical details. Benefits and
side effects will be pulled from medical observations of
the neurostimulator’s usage in Germany and Denmark.
Revised Proposal - According to the World Health
Organization, upwards to 47% of adults suffer from a
headache disorder. [1] Many of those disorders are
debilitating to the individual and prevent a normal life.
Headache disorders are notorious for their lack of an
effective treatment. Most drugs and natural remedies are
often only an attempt to treat the symptoms rather than the
actual cause of the headaches. Neurostimulation, however, is
an effective and efficient way to treat the
headaches. Neurostimulation, via direct connection into
the sphenopalatine ganglion (SPG), blocks the pain-causing
neurotransmitters at the onset of a headache preventing pain
from being registered by the brain. [2]
The neurostimulator is smaller than an almond, weights
1.5 grams, and is 5mm in thickness. The device consists of
three pieces: the neurostimulator body, a lead tip, and a
fixation plate. The neurostimulator is anchored to the
cheekbone on the side of the pain via the fixation plate. This
is done above the second molar during oral surgery. During
the surgery, the lead tip extends into the SPG. From there, the
lead tip has 6 electrodes to stimulate the SPG and block the
pain from being transmitted. The body houses a rechargeable
battery for continued use.
The use of neurostimulation to block pain triggering
nerve clusters allows those suffering from migraines and
cluster
headaches
to
live
normal
lives. Neurostimulation could see widespread use with other
headache disorders. This is an important development
because this process is providing an effective treatment for a
previously
untreatable and
painful ailment. Neurostimulation to treat headaches has the
potential to affect a large portion of the population who suffer
from headache related conditions.
Medicine and technology are converging now more so
than ever. The days of the witchdoctor and quirky tricks are
being replaced by scientific knowledge. Home remedies often
do not work. That’s where bioengineering comes into
play. Engineering’s involvement with understanding how the
body works and combining that knowledge with technology
produces devices such as this neurostimulator to increase the
quality of life for a massive amount of people worldwide. The
study of neurostimulation and its effects corresponds to

This academic journal, from a Russian study on how
headaches affect the quality of life, finds connections between
headaches and public welfare. The authors examine in which
ways headaches affect the general population in multiple

ethical consideration. Will also be used to determine
candidates for neuromodulation.
