Headache impacts the well-being, capacity, and functionality of an individual. Migraine is the most common type of recurrent headache for patients seeking care. It is a complex neurological disorder associated with various symptoms of sensory, autonomic, and cognitive function, suggesting the involvement of multiple neuronal networks. The diagnóstico of migraine warrants both inclusion of specific clinical features and exclusion of other types of headaches. There are many types of headaches that may have “migraineous features”. It is essential to recognize and differentiate “migraine mimics” as they may have some common features with migraine but may also be associated with high morbidity and/or mortality. The diagnostic errors often lead to a therapeutic delay or even malpractice. In this review, the most common “migraine mimics” will be discussed.
