Kevin – it’s funny you mention this. I got my last dose about a week and a half ago and I feel great. Prior to that however – especially the few weeks leading up to it – I was feeling quite fatigued by things that otherwise hadn’t previously made me tired. I knew I had the shot coming up so I wasn’t sure if it was a sort of placebo. And I know the feeling of “having energy” is subjective and difficult to measure for clinicians, but every time I get a dose I feel like I have so much more energy for the next 3 or so months. It’s not as if I am getting stronger. I still can’t lift my arm very high, but I swear by the increase in energy, which in turn feeds forward and improves my mood which I know is not an effect of spinraza, but definitely a secondary downstream effect of having more energy. Additionally – and this point is critical – prior to the injections I had felt myself getting weaker over a time course of a year or so in that I lost the ability to do certain things I was able to do prior. I have not experienced that since getting the injection. If the natural history of our disease is to slowly decline, then halting any further progression – in my opinion – is by definition improving. Aka spinraza = big fan.
So in short, yes. I experience exactly what you are talking about.
