ABSTRACT
Headache disorders are ranked amongst
the ten most disabling conditions in the world by World Health Organization
(WHO). The global prevalence of active headache diseases in the
adult population is 46%. Tension-type headache and migraine are
the two most common headache disorders affecting 42% and 11% adults
respectively. About 3% of the world's population is affected by
chronic headache that lasts for more than 15 days per month.1 While
headache has been an unaddressed cause of morbidity around the world,
it has remained largely unrecognized in the developing world.2 Most
clinical and epidemiological studies have originated in developed
countries and there is scarce literature to support treatment guidelines
or public health interventions to deal with headache in low and
middle income countries where 85% of the world's population lives.
No large study regarding the prevalence of problem has been conducted
in our region of world. However local literature search shows a
prevalence of tension type headaches was up to 48.5 % 3 According
to one study conducted in school children the prevalence of headache
was up to 85 % 4. It gives us some insight about the amplitude of
the problem in our area.......
