Detailed Answer:
Hello!
Welcome to Ask a Doctor service!
I understand your concern and would explain that your mother's symptoms could be related to an inner ear disorder or a viral infection (vestibular neuronitis)
Although she is taking betahistine, it does not have an immediate effect.
Coming to this point, I agree with the doctors that hospitalization and intravenous fluids (including Manitol) may be needed.
I would also recommend performing a brain MRI and labyrinthine tests, to check for an inner ear disorder.
In the meantime, I would recommend starting Dimenhydrinate for the head spinning and nausea.
You should discuss with her doctor on the above treatment options.
Hope you will find this answer helpful!
Kind regards,
Dr. Ilir Sharka, Cardiologist
