The most common symptoms include visual disturbances such as flashing lights, distortion in the size or shape of objects (zigzag), or seeing dark spots in the field of vision.
Some migraines with aura may also include symptoms affecting the nervous system, such as numbness or tingling in the face or arms, strange smells or noises, or weakness on one side of the body. Migraines are more common in adult women than in men. Often tend to occur just before or during menstruation and usually shrink after menopause.
A victim of this problem may have their first attack between 19 and 30 years of age. Migraines can occur several times a week or once every several months. The exact causes of migraines are not clear. Changes in blood flow may be one of the main reasons.
It is important to know the family history and that 75% of cases there is clearly a hereditary connection. Experts have noted a correlation between changes in estrogen levels and migraine suggesting that hormones may also be associated with this problem.
