Symptomatic treatment, palliative symptomatic treatment, yes, fair enough, but it would be really nice if we knew what caused it, because if you know the causation, then you can develop treatment regimes that are designed to stop the problem.
Perhaps she was referring mostly to treatment of the symptoms, but it's difficult. The symptoms are so varied: lassitude, inability to sleep, inability to concentrate, disparate weaknesses, muscle weaknesses, and disparate body pains. The spectrum of symptoms is very wide and is not even consistent between one individual and another. I don't know how you approach this, but I think we do need to find out what caused it. I'm pretty sure of that.
