Migraine is a very common type of headache, particularly among young people. The specific causes and mechanisms of migraine are not very clear at present. The main reasons are attributed to the following: First, vascular dysregulation, where abnormalities in the contraction and dilation of brain blood vessels can disrupt the regulation of blood supply to the brain, leading to headache attacks. Second, abnormal neuron discharges, where some people experience unusual discharges in the neurons of the cerebral cortex, causing migraines. Third, some experts believe that issues with the trigeminal ganglion can cause migraines. Additionally, migraines are closely related to excessive tension, anxiety, depression, poor sleep, and poor physical condition. Therefore, migraine sufferers should pay attention to rest, ensure good sleep, maintain a stable mood, and avoid excessive stress.
