Results showed that 14% of the placebo group reported depression, while 18% of the
Avonex users experienced this effect. So yes,
Avonex can cause depression, but that's not really the question. If this study is to be believed (and I don't know who conducted it, surely not rxlist.com), then more than 4 out of 5 Avonex users did NOT experience depression. Quite a difference from the 100% rate LA's neuro postulates.
