It seems to me that what you are saying could be applied to any medication. It is claimed that Tysabri slows the course of MS but if no one knows how fast it is progressing how can it be claimed that it is being slowed.
For illnesses like MS, where the normal course of the disease involves fluctuations in symptoms, it's very easy for a homeopath to claim success for changes that would have happened anyway.
The same can be said for the chemical treatments available for MS.
Yes, exactly! This is a property of our condition, not of any specific treatment. This is unfortunately why it's so difficult to separate effective MS treatments from ineffective ones, and why anecdotal reports of a drug's success or failure always need to be viewed very skeptically.
Double-blind controlled clinical trials (with lots of people in both the control and treatment groups) are the best means for teasing out real effects. For drugs like Tysabri and the CRABs, large clinical trials have shown that on average
, people getting these medications have better MS outcomes than people who don't get them, in a statistically significant way. That's not to say either group of people is entirely satisfied with their results, nor that every person with treatment does better than every person without treatment, merely that there is a real effect. Homeopathy has failed
this test: overall, people receiving homeopathic treatments do no better than people receiving placebos.
