Headache is one of the most frequent neurological symptoms but migraine is due to raised intracranial pressure and may be accompanied or preceded by vomiting. It may be severe and one sided. It should be differentiated from tension headache or migrainous neuralgia (cluster headache). Usually migraine causes episodes of severe or moderate headache (which is often one-sided and pulsating) lasting from several hours to three days, accompanied by gastrointestinal upsets, such as nausea and vomiting. Women are three times more prone to develop migraine than men.
Cause of migraines is not fully understood but genetics and environmental factors appear to play a role. It may be caused by changes in the brainstem and its interactions with the trigeminal nerve. Along with that hormonal changes, salty foods and processed foods, highly caffeinated beverages and alcohol, disturbed sleep, change in environment, stress are reported be the triggering factors of migraine.
Patient may feel hypersensitivity to light, noise, odour, sun heat, etc. Headache is usually one sided. It is accompanied with gastric disturbance such as nausea and vomiting. There may be blurred vision with headache. Headaches occur very regularly, generally at the same time each day, and they often awaken the person at the same time during the night.
