Migraine
is
a chronic disorder characterized by mild to very severe headaches that are
often associated with symptoms of the autonomic nervous system. The word
migraine comes from the Greek ἡμικρανία (hemikrania), ie "pain on one side
of the head", from ἡμι- (hemi-), "half", and κρανίον (cranion),
"skull".
The sign is a unilateral
headache (on only half of the head), throbbing, and lasts for 2 to 72 hours.
The accompanying symptoms include nausea, vomiting, photophobia (increasingly
sensitive to light), phonophobia (increasingly sensitive to sound) and increasingly
severe pain when performing physical activity. About one-third of migraine
headaches experience an aura: a kind of visual, sensory, speech, or motion
impairment that signs that the headache will soon appear.
Migraine is believed to
occur as a result of a mixture of various environmental and genetic factors.
Approximately two-thirds of cases occur in people who are already married.
Hormonal levels rise and fall can also affect: migraine is slightly more common
in adolescent men than women before puberty, but in adults, about two to three
times more occur in women than men. Migraine trends usually decrease during
pregnancy.
The exact mechanism of
migraine is unknown. However, there is a belief that the disease is caused by
neurovascular disorders. The underlying main theory is the relationship with
increased cerebral cortex stimulation and abnormal control of nerve cells of
pain within the trigeminal nucleus of the brain stem.
The recommended basic
management is with simple analgesics such as ibuprofen and acetaminophen for
headaches, antiemetics for nausea, and avoiding the trigger for migraine.
Special agents such as triptans or ergotamine may be applicable when simple
analgesics are ineffective. More than 10% of the population around the world has
been exposed to migraines at some point throughout their lives.
