If pain is like noise (and it often is) then a “silent” migraine doesn’t seem possible–at least to most migraine sufferers. Nevertheless, researchers claim that silent migraines are true migraines and they may help us understand and treat migraines of all kinds.
The medical oddities described as a silent migraine headaches occur without the migraine pain. How can this be? Unfortunately much about migraines is still a mystery to migraine researchers.
Some of the clues to this mystery may lie in other migraine symptoms such as the aura that often presages or accompanies the headache itself.
Researchers state correctly that migraines are a neurological disorder. So are headaches. What they are trying to tell us is that migraines are a neurological disorder that only is accompanied by a headache some of the time. In fact, that probably should be amended to most of the time. It may be helpful at this point to review the four classic stages that comprise a typical migraine headache:
The Prodrome
This somewhat vague phrase indicates that a migraine is on its way. Psychological symptoms can range from irritability to confusion. Physical symptoms can include excessive thirst, stomach upsets and diarrhea. Prodrome symptoms occur in about a quarter of migraine sufferers. Their elusive nature is accentuated by the fact that they can show up as much as a day before the other stages of a migraine set in.
An Aura
About a fifth of migraine sufferers contend with an aura as one of the early stage of a migraine. Most commonly this stage of a migraine includes disturbances to visual perception. One patient described her aura as “squiggly lines” in front of her face. Other visual effects are also commonly reported. Sensory, motor, and language disturbances are also quite prevalent in the aura stage.
The Pain
The worst and most characteristic migraine symptom is likely to be headache pain. This pain often shows up on only one side of the head and is typically described as throbbing or stabbing pain. Acute sensitivity to light or sound can occur at the aura stage, but are more common at this point. Nausea and vomiting are not uncommon as well. Pain can endure for as long as three full days.
The Resolution
The post-migraine (or perhaps more accurately post-migraine pain) phase is called the resolution phase. This is characterized by profound fatigue and a general feeling of ill health. It can last for another day.
That’s the classic pattern of a serious migraine. Migraine patients can vary in the phases that are experienced as part of their particular neurological event. Simply enough, when pain is hardly present or completely absent as one of the phases a patient has experienced a silent migraine.
The complicated part is figuring out why some migraines progress without intense pain. This has led researchers to theorize that migraine aura and migraine pain are caused by two distinctly different but related mechanisms. The complex relationship between the circulatory system and the nervous system is the direction that their research is taking.
