Headache Fear & The Analgesic Overuse Syndrome/January 2008
In
the management of the Analgesic-Overuse Headache Syndrome, fear is a primary
concern. This fear-of-pain
actually drives the analgesic overuse, accelerates the headaches, resists
treatments, and encourages relapses.
Unless this fear is specifically allayed, the prognosis of this syndrome
is poor. In this terse editorial,
I shall discuss the Analgesic-Overuse Headache Syndrome and the specific
management of the fear that propels it.
In
the headache field, numerous published studies support the concept that
analgesic overuse is primarily responsible for the Transformed Migraine
Syndrome. The Transformed Migraine Syndrome represents the progressive increase
in the frequency and severity of headaches—from that of the natural migraine
rhythm of few headaches per month to that of a daily or near daily headache
that defies preventive treatments.
Analgesic overuse is defined as the taking of more than two doses of
anti-headache pills per week, the dose being one or two tablets. The analgesics overused include the
non-steroidal anti-inflammatory drugs, triptans, acetaminophen, narcotics, and
all other medications that are utilized to reduce headache pain.
The
Analgesic-Overuse Headache Syndrome is a major confounder of preventive
therapies because it is commonly overlooked by treating physicians. Consequently, patients who unwittingly
continue to overuse their headache-analgesics also continue to fail accepted
treatments. A careful headache
history is mandatory to uncover such analgesic habits because patients almost
always underestimate their analgesic use and seldom volunteer that information
unless specifically interrogated.
Addressing
the Analgesic-Overuse Headache Syndrome and asking patients to desist from
using analgesics is seldom enough.
This is because stopping the analgesics causes rebound headaches, which
frighten the patients back into analgesic overuse. The magnitude of fear among these headache sufferers is most
impressive when subjected to quantization. (H.A.Saadah MD, HEADACHE FEAR. Journal of the Oklahoma State Medical
Association 1997; 90:179-184.)
To
affect recovery, the rebound headaches have to be tempered. This can be done by giving a
long-acting cortisone injection at the time of analgesic discontinuation. For patients with a low fear score,
this simple intervention may be sufficient. However, for those with a high fear score, the fear will
have to be allayed before they are able to stop analgesics. Experience has shown that the success
of analgesic cessation is inversely proportional to the fear score. When the fear is high, education alone
is seldom enough to affect analgesic cessation and a fear transposition becomes
necessary.
The
fear transposition is done with a simple analogy. The patient is asked to imagine himself a prisoner under the
rule of a jailer who comes each morning, opens his jail cell, and whips him
brutally. Then the patient is
asked what frightens him most, the whip or the jailer? Most patients chose the whip and will
need to be reminded that the whip cannot whip them without the jailer’s hand
and that the jailer can beat them up without the whip. Once they realize that, then they are
told that the jailer is their overuse of analgesics while the whip is their
headache. After they internalize
this concept, they are then asked to become afraid of the analgesics instead of
the headaches.
What
had actually caused the analgesic overuse was the fear of headache pain rather
than the pain itself. This fear is
now allayed by transposition from a fear of pain to a fear of analgesics. The power of this fear is now harnessed
to reinforce the abstinence from analgesics, which is what the patient needs to
recover.
