I am confused when participants in drug trials claim that their symptoms improve or are less severe.
From my understanding of ALS, actual improvements will only occur when the dead motor neurons are regenerated or replaced with new ones. An incredibly tricky process.
Our bodies cannot regenerate motor neurons on their own. And I am not aware of any of the trial drugs being designed to, or claiming that they can, regenerate motor neurons. I mean, if any of the drugs were designed to regenerate motor neurons they would be tested on and marketed to a larger affected population (maybe spinal cord injuries?).
I can understand trial drugs maybe slowing progression (wouldn't that be great) but I can't understand claims of return of lost function.
I have always understood any cure for ALS as being a two stage affair. 1. Stop progression and 2. Regenerate motor neurons.
Drugs are targeting progression but I think we will need to rely on stem cell therapy to regenerate motor neurons and effect actual improvements.
So how can participants in drug trials be experiencing any improvements?
I would love it if was true - I just don't understand it.
