I must say David @Indra that this type of comment from a doctor or health professional is very annoying and in my view unnecessary, I believe they say it to “set realistic expectations”, but the truth is nobody actually knows what can be expected and what the outcome will be. We see time and again people making recovery and progress at their own pace and perhaps they are helped with a gentle nudge in the right direction even faster 
And in this case, I can only guess the doctor was “naturally” responding to the comment made by the neurologist
And in some ways I can understand that too, since someone else in your situation might be seeking reassurance that OK, this is indeed as good as it gets i.e. after three years.
So I can see both points of views and perhaps both are valid and as individuals we choose the path we wish to follow.
I wish you success in achieving your goals.
Namaste|
