· Pulsing and throbbing head pain

· Increasing pain at physical activity

· Not able perform regular activities due to pain

New developments on migraine symptoms from MNT news

 

Researchers  and experienced from INSERM, the French National Institute of Health and Medical Research in Bordeaux, and Brigham and Women's Hospital in Boston, found that women who have migraines with aura have a higher risk of heart attack, while those taking newer contraceptives may have a greater risk of blood clots.

 

How is migraine diagnosed?

 

Firstly Physicians look at family medical history and check the patient for the symptoms explained above in order to diagnosis of migraine.

 

The International Headache Society recommends the "5, 4, 3, 2, 1 criteria" to diagnose migraines without aura.

 

It stands for:

 

5 or more attacks

 

4 hours to 3 days in duration

 

At least 2 of unilateral location, moderate to severe pain pulsating quality, aggravation by or avoidance of routine physical activity

 

At least 1 additional symptom such as:

 

· nausea

· Vomiting

· Sensitivity to light

· Sensitivity to sound

Tests:

 

Some Tests such as

 

1. electroencephalography (EEG)

2. computed tomography (CT)

3.  magnetic resonance imaging (MRI)

Spinal tap can also be performed that check for:

 

· Bleeding within the skull

· Blood clots within the membrane that covers the brain

· Stroke

· Either too much or too little cerebrospinal fluid

· Dilated blood vessel in the brain

· Nasal sinus blockage

· Postictal headache (after stroke or seizure)

· Tumors

· Inflammation of the or spinal cord or  membranes of the brain

Treatment and prevention

 

These include:

 

· Getting enough sleep

· Reducing stress

· Drinking plenty of water

· Avoiding certain foods

· Regular physical exercise.

Migraine treatment (abortive therapies) and prevention (prophylactic therapies) focus on avoiding triggers, controlling symptoms and taking medicines.

 

Medications:

 

Medications such as:

· Naproxen

· Ibuprofen

· Acetaminophen (paracetamol)

Other analgesics like:

 

Excedrin (aspirin with caffeine) are often the first abortive therapies to eliminate the headache or substantially reduce pain.

 

Anti-emetics may also be used to control symptoms such as nausea and vomiting -

 

Serotonin agonists such as sumatriptan may also be prescribed for severe migraines or for migraines that are not responding to the over-the-counter medications. As like some selective serotonin reuptake inhibitors (SSRIs) -antidepressants such as tricyclics - are prescribed to reduce migraine symptoms although they are not approved in all countries for this purpose.

 

Another kind of abortive treatment is called ergots, which are usually effective if administered at the first sign of migraine.

 

Other drugs have also been used to treat migraine such as combinations of paracetamol or aspirin, barbituates and caffeine (Fioricet or Fiorinal) and combinations of acetaminophen, dichloralphenazone, and isometheptene (Amidrine, Duadrin, and Midrin).

 

Prophylactic therapies (prevention)

 

Migraine can only prevent by avoiding things that trigger the condition. Exactly prophylactic therapies reduce the pain and duration of migraine headaches and to increase the effectiveness of abortive therapies.

 

There are many more categories of migraine medicine, ranging from diet changes and exercise to prescription drugs.

 

This includes:

 

Prescription beta blockers, anticonvulsants and antidepressants

 

Botulinum toxin A (Botox)

 

Herbs and vitamins such as:

 

· butterbur

 

· cannabis

 

· coenzyme Q10

 

· feverfew

 

· magnesium citrate

 

· riboflavin

 

· B12

 

· melatonin

 

There is some Surgery that severs corrugator supercilii muscle and zygomaticotemporal nerve in the brain

 

Spinal cord stimulator implantation

 

Hyperbaric oxygen therapy

 

Vision correction

 

Exercise, sleep, sexual activity

 

Visualization and self-hypnosis

 

Chiropractic care or acupuncture

 

Special diets such as gluten free

 

It is possible for people to get medication excessive use headache (MOH), or rebound headache, when taking too many medications in an attempt to prevent migraine.
