@elmerlin It would be good if she were treated directly by a neurologist, but no one else. Headaches can be caused by thousands of things, but the main one is the neurologist. I arrived at my diagnosis by performing an MRI at the brain level and an electroencefalograma, which is what indicates the electrical activity of your head. If everything goes well there then visit another specialty such as a dentist, gynecologist, ophthalmologist, the idea is to rule out until you get to the problem, at least that's what happened to me. I hope your mom finds a solution soon.
