Migraine experience: what are the causes of migraine

summary

What are the causes of migraine? Migraine is a very common symptom. Everyone has experienced migraine in his life. However, due to a variety of causes of migraine, many people do not know why they have migraine and what are the causes of migraine.

Migraine experience: what are the causes of migraine

First, the onset of migraine lasts from a few hours to a few days. In some cases, it lasts more than a year. The concurrent symptoms include temporary blindness, vomiting, tremor and stroke related symptoms, such as local trunk numbness. Migraine often occurs on one side of the head, but it can also occur on both sides. Many patients also say that their location of the disease often deviates.

Second, it was once thought that vasodilation was the cause of migraine, because it could cause pain and aura (lines, colors, irregular graphics or blind spots would appear in the vision of patients before migraine attack), but new evidence shows that some concurrent factors are the real cause of migraine, such as the release of chemicals and the enhancement of pain sensitivity. Doctors have begun to classify migraine into the category of neurobiological pathology, or that the root of the disease lies in the brain.

Third: another mistake is that migraine is not equal to simple headache. Usually headache is caused by vasoconstriction, while the cause of migraine is vasodilation.

matters needing attention

During a migraine attack, the surrounding brain tissue swells, causing severe pain. Most of the drugs used to treat headache are used to dilate blood vessels, which only aggravate the symptoms of migraine. Therefore, the correct diagnosis of migraine is very important and necessary.
