Routine screening is not appropriate because of the rarity of the conditions and the high cost of screening. Some types of hyperlipidaemias are risk factors for vascular disease. The category should be assessed according to the type and its severity. The extent to which risk with CICs is similar to COCs remains unclear. Any new headaches or marked changes in headaches should be evaluated.
Classification is for women without any other risk factors for stroke.
Risk of stroke increases with age. Among women with migraines, women who also have focal neurologic symptoms have a higher risk of stroke than those without focal neurologic symptoms. In addition, among women with migraines, those who use COCs have a 2 to 4 fold increased risk of stroke compared to women who do not use COCs. The extent to which risk with CICs is similar to COCs remains unclear. The condition, as such, is not a concern.
