Migraine is a clinical syndrome that exists for many years in the patient's life, has pain attacks that can last from a few hours to a few weeks, has many accompanying symptoms, and does not have a headache complaint between attacks. Migraine headaches, in which genetic characteristics may be effective in their development, can generally be defined as a unilateral headache accompanied by nausea and sensitivity to light and sound. During migraine attacks, the quality of life of migraine patients is lower than the general healthy population. The risk of migraine in children of people with migraine in their families is higher than in the general population.

Migraine, a disease in which genetic and environmental factors play a role together, is not a purely genetic disease. There are two main subtypes: migraine with aura and migraine without aura. Migraine with aura, which constitutes 10% of migraine attacks, manifests itself with temporary sensory symptoms such as hallucinations in the form of zig-zag lines, blurred vision, flashes of light or the presence of gaps in the field of vision known as scotomas, approximately one hour before the development of the headache.

It may also be accompanied by other symptoms such as dizziness, numbness, tingling, weakness in the arms and legs, loss of sensation and confusion of words. The presence of an aura is not an indicator of attack severity. Migraine attacks without aura can be as severe as migraine attacks with aura, or they can be more severe.
