Up everything you can up as far as insurance goes. Think life, long term care, short and long term disability, etc. She does not have a diagnosis yet and as long as she doesn't, and hasn't been "treated" for MS, you can answer their questions honestly. Even if they challenge her if and when she ever needs the insurance, she is NOT a doctor and cannot diagnose herself, and that has been tried and decided already in court and the ruling was in favor of the insured.

More than likely she will not immediately need those insurances, and she may NEVER need them, but get them while you can.
