Migraine is a primary headache disorder characterized by recurrent headaches that are moderate to severe.Typically, the headaches affect one half of the head, are pulsating in nature, and last from two to 72 hours.Associated symptoms may include nausea, vomiting, and sensitivity to light, sound, or smell.
There are four possible phases to a migraine, although not all the phases are necessarily experienced:
The prodrome, which occurs hours or days before the headache
The aura, which immediately precedes the headache
The pain phase, also known as headache phase
The postdrome, the effects experienced following the end of a migraine attack The underlying causes of migraines are unknown. However, they are believed to be related to a mix of environmental and genetic factors.They run in families in about two-thirds of cases and rarely occur due to a single gene defect. While migraines were once believed to be more common in those of high intelligence, this does not appear to be true. A number of psychological conditions are associated, including depression, anxiety, and bipolar disorder, as are many biological events or triggers.
Preventive treatments of migraines include medications, nutritional supplements, lifestyle alterations, and surgery. Prevention is recommended in those who have headaches more than two days a week, cannot tolerate the medications used to treat acute attacks, or those with severe attacks that are not easily controlled.
