an imaging technique that provides a picture, called an
angiogram, of blood vessels.
a symptom of classic migraine headache in which the patient
sees flashing lights or zigzag lines, or may temporarily lose
basilar artery migraine:
migraine, occurring primarily in young women and often
associated with the menstrual cycle, that involves a disturbance of
a major brain artery. Symptoms include vertigo, double vision, and
poor muscular coordination.
headache brought on by running, lifting, coughing, sneezing, or
a technique in which patients are trained to gain some
voluntary control over certain physiological conditions, such as
blood pressure and muscle tension, to promote relaxation.
helps patients consciously raise hand
temperature, which can sometimes reduce the number and intensity of
intensely painful headaches-occurring suddenly and lasting
between 30 and 45 minutes-named for their repeated occurrence in
groups or clusters. They begin as minor pain around one eye and
eventually spread to that side of the face.
computer tomography (CT):
an imaging technique that uses X-rays and computer analysis to
provide a picture of body tissues and structures.
a drug that is given by injection to treat cluster headaches.
It is a form of the antimigraine drug ergotamine tartrate
a technique for recording electrical activity in the
a special recording technique that detects electric activity in
muscle. Patients are sometimes offered a type of biofeedback called
EMG training, in which they learn to control muscle tension in the
face, neck, and shoulders.
naturally occurring painkilling chemicals. Some scientists
theorize that people who suffer from severe headache have lower
levels of endorphins than people who are generally pain free.
a drug that is used to control the painful dilation stage of
a type of migraine causing temporary paralysis on one side of
a headache that is a symptom of another disorder, such as sinus
infection, and is treated by curing the underlying problem.
magnetic resonance imaging
an imaging technique that uses radio waves, magnetic fields,
and computer analysis to provide a picture of body tissues and
a vascular headache believed to be caused by blood flow changes
and certain chemical changes in the brain leading to a cascade of
events - including constriction of arteries supplying blood to the
brain and the release of certain brain chemicals - that result in
severe head pain, stomach upset, and visual disturbances.
headaches caused primarily by sustained muscle tension or,
possibly, by restricted blood flow to the brain. Two forms of
muscle-contraction headache are
chronic muscle-contraction headache
which can last for extended periods, involves steady pain, and is
usually felt on both sides of the head.
the endings of pain-sensitive nerves that, when stimulated by
stress, muscular tension, dilated blood vessels, or other triggers,
send messages up the nerve fibers to nerve cells in the brain,
signaling that a part of the body hurts.
a form of migraine felt around the eye and associated with a
droopy eyelid, double vision, and other sight problems.
naturally occurring pain-producing substances thought to be
implicated in migraine attacks. Their release is triggered by the
dilation of arteries. Prostaglandins are extremely potent chemicals
involved in a diverse group of physiological processes.
a key neurotransmitter that acts as a powerful constrictor of
arteries, reducing the blood supply to the brain and contributing
to the pain of headache.
an infection, either viral or bacterial, of the sinus cavities.
The infection leads to inflammation of these cavities, causing pain
and sometimes headache.
a rare, sustained, and severe type of migraine, characterized
by intense pain and nausea and often leading to hospitalization of
a technique sometimes used for diagnosing headache in which an
infrared camera converts skin temperature into a color picture,
with different degrees of heat
appearing as different colors.
a disorder of the joint between the temporal bone (above the
ear) and the lower jaw bone that can cause muscle-contraction
headaches caused by pulling or stretching pain-sensitive parts
of the head, as, for example, when eye muscles are tensed to

a condition resulting from a disorder of the trigeminal nerve.
Symptoms are headache and intense facial pain that comes in short,
headaches caused by abnormal function of the brain's blood
vessels or vascular system. Migraine is a type of vascular
