Migraines
What is it?
▪ A severe painful headache with no cure
▪ Accompanied or preceded by sensory warning signs such as
▪ flashes of light
▪ blind spots,
▪ tingling in the arms and legs
▪ nausea
▪ vomiting
▪ increased sensitivity to light and sound
▪ Usually affects one side of the brain
Effects of Migraines According to research the pain is caused by the release of
certain brain chemicals, alterations in blood flow linked
with constriction, dilation of arteries carrying blood to the
brain, and inflammation.
Among the biochemical changes associated
with migraine are abnormal levels of the
neurotransmitter serotonin.
In more than 40% of cases, however, the pain may be
bilateral and neck pain is commonly associated with it.
Bilateral pain is particularly common in those who have
migraines without an aura. Less commonly pain may
occur primarily in the back or top of the head. The pain
usually lasts 4 to 72 hours in adults

women; 1/3 men, aged 18 to 50.
Seven per cent of female migraine sufferers

children, 13 per cent of migraine sufferers have
had to take days off work, and 18 per cent
report that they "can't do anything" and had to
stop their daily activities and/or sleep.
No reports of death due to migraines.
Causes
It remains unsure what causes the migraine headache.
Main factors can be categorized into two subgroups.
Passive factors
▪ Genetics – hereditary
Active factors
▪ Stress
▪ Diet
▪ Exercise
▪ Sleep
▪ Barometric Pressure
Prevention
Drugs that may reduce the frequency of attacks
▪ Beta blockers such as propranolol
▪ Heterocyclic antidepressants such as amitriptyline
▪ Calcium channel blockers such as verapamil
▪ Anticonvulsants such as valproic acid.
Beta blockers reduce
blood pressure by
blocking out
adrenaline .
heterocyclic antidepressant
inhibits the nerve cells'
ability to reuptake
norepinphrine and
serotonin.
Calcium channel blockers
prevent calcium from
entering cells of the heart
and blood vessel walls,
resulting in lower blood
pressure. Calcium channel
blocker. Anticonvulsants increasie
the amount of a certain
natural substance in the
brain.
Other Ways Of Prevention
Besides medicine migraine can be prevented by changing lifestyles.
▪ Maintain a healthy diet. Take rest. Work out daily. Sleep enough.
▪ Quit smoking, it is one of the main factor to cause headache.
▪ Make a schedule to record when the headache happens, so it is easier to know when to prevent it.
Three Categories of Migraines
Retinal migraine
Chronic migraine
Probable migraine
Migraine headaches
accompanied by visual
disturbances or even
temporary blindness in one
eye
Complication of
migraines, a headache
that fulfills diagnostic
criteria for migraine
headache and occurs for a
greater time interval.
Specifically, greater or
equal to 15 days/month
for longer than 3 months
Probable migraine describes
conditions that have some
characteristics of migraines.
However there is not enough
evidence to diagnose it as a
migraine with certainty
(in the presence of concurrent
medication overuse).
History
An early description consistent with migraines is contained in the Ebers papyrus, written around 1500 BCE in ancient Egypt
In 200 BCE, writings from the Hippocratic school of medicine described the visual aura that can precede the headache and a partial relief occurring through vomiting.
Trepanation, the deliberate drilling of holes into a
skull, was practiced as early as 7,000 BCE. While
sometimes people survived, many would have
died from the procedure due to infection. It was
believed to work via "letting evil spirits escape".
William Harvey recommended trepanation as a
treatment for migraines in the 17th century.
Further Inquiry
Acupuncture is said to remedy migraines that have already begun.
More research should be done to prove or disprove that theory.
