It all depends on whether it is a structural thing that is established during fetal development, which can not be fixed post birth, or whether it is part of the brains's development post birth. There is a shit ton of brain development post birth -- not structural (the growth of the initial neurons) but in weeding out pathways and reinforcing certain pathways. A lot of it is based on complex feedback between activity, neurochemical releases and receptors. All of that is fair game to change post birth. Given that autism (like many other psychology labels) is a label for a diverse group of disorders which we can not fully tease apart accurately at this stage, it is likely true that some forms of autism can be treated post-birth, but others will not be.
