So the recommendations are as follows:
1, high field intensity head MRI review, such as 3.0. Pay attention to the presence of meningioma, cholesteatoma, acoustic neuroma, etc., except for the presence of the brain stem next to the meningioma. Can also check the vascular malformation and other items (if your original film is very good, the hospital level is high enough, you do not need to do)
2, the line of foaming experiment, the main check except the possibility of the heart oval hole is not closed, (ordinary cardiac ultrasound, it is not easy to check out of the heart) (this disease is generally common for the headache, you are not quite like, you can further improve the test)
3, the head of CTA and cervical vascular color ultrasound, except vascular origin. Your attacks are not regular, not quite like.
4.Elective checking of 24 hours dynamic EEG to except the possibility of atypical epilepsy.
Because of your long history, the progression is not significant. Consider it better to BBPV. You can do the above tests one by one and rule out the diseases I mentioned, if they are all normal and the report is authoritative enough. Basically, it is BBPV.
