Lynn,
I’m so pleased for you and your Mum -- that the lines of communication are opening up. There is absolutely nothing wrong with you, her or your Dad calling her neurologist’s nurse simply stating that she is not doing as well as we expected and could the doc see her for a reassessment of her medications? The 6 month spacing of appointments is for maintenance, when things are going swimmingly. If your car was slipping in performance I suspect you’d take it in right away for repair. Please let us know how she gets along. All the best. Guy
