Migraine is a benign and recurring syndrome of headache associated with other symptoms of neurologic dysfunction which includes sensitivity to light, sound, or movement; nausea and vomiting.
It is the second most common cause of headache, afflicting approximately 15% of women and 6% of men.
Migraine headache can be initiated or amplified by various triggers, including glare, bright lights, sounds, or other afferent stimulation; hunger; excess stress; physical exertion; stormy weather or barometric pressure changes; hormonal fluctuations during menses; lack of or excess sleep; and alcohol or other chemical stimulation.
Migraine is commonly seen at the end of a period of severe stress, and this is seen in its simplest form as a tendency for attacks to be present on waking in morning, especially at weekends.
The role of dietary factors assumes a very minor position in the provocation of migraine. Sometimes, a sudden ravenous hunger, often of sweet foods can be a warning sign for impending attack of migraine.
