Silent Migraines: Headache Without a Headache

Posted by on Jan. 07, 2013

A migraine is a neurological disorder that commonly manifests through excruciating headaches. In fact, headaches are so closely attributed to migraines that sometimes, we confuse the two as one and the same. That’s why it still remains a mystery how a certain type of migraine—so-called “silent migraines”— don’t actually include headaches in its symptoms.

Migraine attacks are said to undergo four distinct phases, namely prodrome, aura, headache, and postdrome. While a silent migraine displays the same symptoms such as diarrhea, nausea, vomiting, food cravings, loss of appetite, thirst, increased urination, chills, fatigue and auras, it doesn’t involve the typical headache we have always known to be a part of any good old migraine.

Contrary to popular belief, a migraine is not merely a problem with the blood flow in the brain, which is probably the reason why, in the unusual case of silent migraines, headaches do not exist. It was recently discovered that migraines involve nerve-cell activity that relates to the blood flow in the brain, making it a neurovascular event. Researchers are still studying the matter further, and rest assured that we’ll give you the lowdown once there are updates available.
