Overview

Migraine is the intense throbbing or pulsing sensation in one or both parts of the head and is accompanied by uneasiness and extreme sensitivity to light, sound and smell. In some occurrences, migraine is preceded or accompanied by sensory warning symptoms or aura such as flashing of lights, blind spots or tingling of arm or leg. Migraine attacks can last for hours to days.

Types of Migraine

The 2 main types of migraine include:
  • Migraine without aura (Common migraine) . As the name implies, it is the most common type of migraine, characterized by a throbbing pain on one side of the head. If untreated, it may last from 4 to 72 hours. This type of migraine has the risk of worsening with frequent use of symptomatic medication. It does not begin with an aura.
  • Migraine with aura (Classic/Complicated migraine) . Some migraines begin with an aura up to 30 minutes before the migraine attack. Aura refers to neurological disturbances people ?see? before migraine. Aura can be in a form of flashing lights, zig-zag patterns or objects appearing distorted. Migraine with aura can occur without a headache or tension type headache. Other symptoms include nausea, loss of appetite and sensitivity to light or sound.
Other types of migraine include:
  • Migraine with brainstem aura (basilar migraine). This type of migraine causes loss of balance or dizziness before the headache. It may also cause slurred speech, poor muscle coordination, ringing in the ears and even loss of consciousness prior to headache. Headache suddenly comes and if felt on both sides at the back of the head.
  • Abdominal migraine mostly affects children. It may cause nausea, vomiting or dizziness without headache which persists for one to 72 hours.
  • Menstrual migraine. As the name suggests, it affects women as an effect of hormone fluctuation prior to menstrual cycle.
  • Chronic migraine or transformed migraine. This type of migraine occurs up to 15 days or more each month in at least 3 consecutive months. It mostly affects one side of the head which include a throbbing and pulsating sensation on the area affected by the headache which may worsen due to physical activity such as walking or cleaning.
  • Retinal or ocular migraine. This type of migraine may cause visual disturbances such as vision loss or blindness preceding a migraine headache. This condition is rare. Other symptoms include nausea and sensitivity to sound and a headache that worsens with physical activity.
  • Hemiplegic migraine is a rare type of migraine which causes temporary paralysis on one side of the body which may last for several days prior to or during a headache. Other symptoms resemble stroke, such as disturbances in speech and vision.
  • Status migraine or status migrainosus is a serious and rare type of migraine that can last up to 72 hours. This type of migraine can be so severe and prolonged that hospital treatment is needed to relieve nausea or vomiting and prevent dehydration. Along with headache, symptoms include vision changes (aura) and difficulty in thinking and sleeping.
