Migraines are severe, but why can’t I find out the cause? To date, there is no clear medical statement on the cause of migraine, and for migraine patients, various tests, including MRI scans, do not reveal any lesions. On the other hand, if intracerebral lesions are detected by MRI scans, the diagnosis of migraine is often denied, which should be taken seriously by patients and doctors. This is because it may be a headache of other origin, i.e., an organic brain disease that causes migraine-like attacks. The differential diagnosis of headache is not easy. It mainly depends on the old medical history, location, accompanying symptoms, etc. If your family members are engaged in medical-related work, communication can be relatively easy. However, those who are engaged in medical work know very well that it is very easy to misdiagnose and mistreat a headache based only on the patient’s description and without the doctor’s personal examination. Therefore, it is recommended to go to the local hospital to see a doctor.
