The 30% on average is a statistic. There’ll be people who have 100% reduction of relapses/potential relapses and people who maybe will have no reduction in potential relapses/actual relapses.
It also comes from the years before the DMDs were widely available. I started Rebif in 2000 and was told this, but the number was already more than 5 years old.
Now, with better MRI imaging and more MRIs performed the numbers could (in my opinion, should) be quite different.
The DMDs were made available to those who qualified in 2002, in the UK.
The prescribing guidelines were quite strict. However, in the US, where neuros have been paid to prescribe various drugs, the DMDs were offered to anyone with an MS diagnosis who could pay. This means that people with SPMS and PPMS were given drugs that don’t work for their type of MS.
The simple truth is, if you are relapsing, you are ill. The relapse will cause a lesion in your brain - a hole which will fill with liquid and you will suffer some disability - albeit temporary in some or many cases.
I never want another relapse. I know that in the next 3 years or so, I’ll have another relapse.
There’s no way to tell if you’ll progress or not, or if you’ll have brain atrophy. I’ve been lucky in that I haven’t progressed in all that time.
I have residual damage from relapses, I can’t bend my knees, I can’t judge distance on my right side and I can’t do a whole week’s work. I have problems with my vision and I can’t drive a car, as my spatial judgement is impaired.
You may find that you are lucky with side-effects. I’ve been very fortunate, in that I haven’t had the aches or pains or shivers.
I believe that less relapses/no relapses is a goal that can be achieved. Relapses are bad. Full stop.
