IIH and chiari

My girlfriend has IIC caused by a chiari malformation at the base of her spine. She was diagnosed by a ophthalmologist 9 months ago via MRI but is just now able to see a neurologist about it in a few days. Since March her symptoms have gotten much worse to the point her headaches are making her not want to do anything including remembering to eat. Eating is also causing nausea. Her symptoms include vision loss, migranes, memory loss, and sometimes tremors.

What should we be doing to help the IIC at home and what should we be asking thr neurologist next week to do?
