Abstract:Migraine without aura is a common primary headache. Repeated episodes may increase the risk of heart and cerebrovascular disease. It may increase the risk of subtle lesions in certain brain regions and may lead to neurological impairment in certain brain regions, which can seriously affect the quality of life of patients. This paper reviews the progress of neuroimaging studies on migraine without aura based on several commonly used brain imaging techniques, aiming to provide imaging help for clinical diagnosis of migraine without aura.
