Migraine Headaches

This often severe, throbbing type
of headache is different from other types of headaches. Symptoms other than pain can
occur with a migraine headache. Nausea and vomiting, lightheadedness, sensitivity
to
light (photophobia), and other visual changes are common. A migraine headache may
last
from 4 to 72 hours.

Migraines are also unique in that
they have distinct phases. But not all people have each phase. The phases of a migraine
headache may include:

• Premonition phase. A change in mood
  or behavior may occur hours or days before the headache.
• Aura phase. About one-third of people
  who have migraine headaches describe having an unusual “feeling” or aura before the
  headache. The aura phase includes visual, sensory, or motor symptoms that occur just
  before the headache. Examples are hallucinations, numbness, changes in speech, visual
  changes, and muscle weakness. Migraine sufferers may or may not have an aura before
  the start of the headache.

• Headache phase. This is the period
  during the actual headache. Throbbing pain occurs on one or both sides of the head.
  Sensitivity to light and motion is common. So, too, are depression, fatigue, and
  anxiety.
• Headache resolution phase. Pain
  lessens during this phase. But it may be replaced with fatigue, irritability, and
  trouble concentrating. Some people feel refreshed after an attack, while others do
  not.

Headaches are classified as with or without aura.

Experts are not certain what causes a migraine headache. Many experts think an imbalance
in brain chemicals, such as serotonin, and changes in nerve pathways are involved.
Migraines may also run in families suggesting a genetic link.

These are the most common symptoms
of migraine headaches:

• Throbbing, severe headache pain with a
  specific location either on one side or both
• Nausea and vomiting
• Lightheadedness
• Sensitivity to light or sound
• Visual changes, such as a flashing
  light or even lack of sight, for a short period of time
• A change in mood or behavior hours or
  days before the headache
• Depression, fatigue, or anxiety
• Fatigue, irritability, and
  trouble concentrating as the headache goes away

These symptoms may look like other
health problems. Always see your healthcare provider for a diagnosis.

Migraine headaches are diagnosed
based on your symptoms and a physical exam.

Tracking and sharing information
about your headache with your healthcare provider helps with the diagnosis. Write
down
the following:

• Time of day when your headaches
  occur
• Specific location of your
  headaches
• How your headaches feel
• How long your headaches last
• Any changes in behavior or
  personality
• Effect of changes in position or
  activities on the headache
• Effect of headaches on sleep
  patterns
• Level of stress in your life
• Details about any head trauma, either
  recently or in the past

If you have unusual symptoms or
the findings from your exam aren’t normal, your healthcare provider may want you to
have
other tests or procedures. These can rule out underlying diseases or health problems.
These tests include:

• Blood tests. Various blood chemistry
  and other lab tests may be used to check for underlying health problems.
• Sinus X-rays. This X-ray checks for
  congestion or other problems linked to the headaches.
• MRI. This test uses a combination of
  large magnets, radio waves, and a computer to make detailed images of organs and
  structures.
• CT scan. This test uses X-rays and
  computer technology to make images of the body or head. CT scans show more detail
  than standard X-rays.
• Spinal tap (lumbar puncture). A
  special needle is placed into the lower back, into the spinal canal, which is the
  area around the spinal cord. The pressure in the spinal canal and brain can then be
  measured. A small amount of cerebrospinal fluid (CSF) can be removed and sent for
  testing to check if there is an infection or other problems. CSF is the fluid that
  surrounds the brain and spinal cord.

Treatment will depend on your symptoms, age, and general health. It will also depend
on
how severe the condition is.

Certain medicines can help treat or
prevent migraine headaches:

• Abortive medicines. These medicines
  are prescribed by your healthcare provider. They act on specific receptors in both
  the brain and the blood vessels in the head, stopping a headache once it has
  started.
• Rescue medicines. These are
  medicines purchased over-the-counter, such as pain relievers, to lessen or stop the
  headache.
• Preventive (prophylactic) medicines.

  These medicines are prescribed by your healthcare provider. They are taken
  regularly to stop the start of severe migraine headaches.

Complications of migraine headaches may include:

• Severe headache pain, often in one part of your head, such as near one eye
• Potential nausea and vomiting
• Immobility and lack of activity
  because of severe pain
• Loss of work time and personal time

The goal of treatment is to prevent
migraines from occurring. You can help do that by:

• Staying away from known triggers, such
  as certain foods and beverages like caffeine, lack of sleep, and fasting
• Changing eating habits
• Getting regular exercise
• Sticking to a regular sleep schedule
• Resting in a quiet, dark place
• Taking medicines, as advised by your
  healthcare provider
• Managing stress
• Getting therapeutic massage
• Taking prescribed medicine as
  directed

Some headaches may require care right away, including going to the
hospital for observation, and diagnostic testing. Call your healthcare provider right
away if you have a migraine headache with:

• Stiff neck
• Fever
• Convulsion
• Shortness of breath
• Confusion
• Muscular weakness
• Double vision
• Change in level of consciousness

• A migraine is a severe, throbbing type of headache.
• Nausea and vomiting, lightheadedness, sensitivity to light (photophobia), and other
  visual disturbances are common migraine symptoms.

• Preventing a migraine headache is
  often the most helpful approach for treatment.
• Migraine headaches can have a
