Sociodemographic characteristics of patients with chronic headache
Introduction
H
eadache
is an entity characterized by a painful process in the
cephalic segment, may originate from cranial or facial structures,
being considered a common medical complaint
1,2
. This may also
occur episodically or chronically and may be classied in primary
or secondary.
Chronic headache may be associated with several reasons, one of
them being the abusive use of painkillers. Abusive use is characterized
by the use of simple analgesics for 15 days or more in a month or,
for triptans, ergotamines, opioids, caffeine and combined painkillers
for 10 or more days in a month
3-5
.
In addition, one can list as risk factors for the painfull process
chronication in the cephalic region: ineffective treatment of hea-
dache, obesity, psychiatric disorders, being female, low education,
daily stresses

. In this perspective, besides the clinical diagnosis of
headache type, it is of extreme importance to identify the potential
comorbidities that are chronifying factors, aiming at treating them
and thus avoiding the aggravation of chronication.
Thus, it was noted the need to analyze the epidemiological prole
of patients attended at the Unifacisa’s outpatient neurology cli-
nic. Mainly to determine if the demand for attendance occurs by
following the global epidemiological pattern or another, as well
as generating knowledge about the patients’ own prole attended
in this service.
Material and Methods
The research was conducted through a retrospective cross-sectional
study, performing the analysis of medical records of patients seen
at the Unifacisa’s outpatient neurology School Clinic complaining of
chronic headache, from February 1st to August 31, 2019, following
the classication criteria of the International Classication of Hea-
daches Disorders (ICHD-3). All patients were included, regardless
of gender or age, that met criteria for chronic headache, whether
primary or secondary, being excluded all patients who had heada-
che but did not meet the ICHD-3 chronication criterion or had not
yet received a diagnosis of headache.

Conclusion
Although a small number of chronic headache patients were obtai-
ned, since headache is one of the major medical complaint and the
highest prevalence of CTTHs in the general population, yet we realize
that it is the migraine that leads to a greater demand for specialized
medical care. Therefore, it is evident how migraines compromise
both the functionality of the individual, as well as the quality of life.
Moreover, the high and disproportionate prevalence of females over
males, evading epidemiological patterns for headache, is supposed
