Well refusing to get a diagnoses doesn't make it so you don't have it if you do..but there is no cure, since a different way of the brain working as far as I know its not even clearly defined how but it is different enough to where a 'cure' would be much more complex than anything most people could fathom and be a lot more invasive than say taking a valium for anxiety attacks...not the same as having people screw with your brain trying to re-wire it to whatever normal neurology is. There supposedly is help for it, I have not seen much of this especially if you're an adult...aside from it could help with getting SSI if you can't work...as for that label well having the diagnoses might help explain things, but if that is all it would do not sure there is much point to bothering since diagnoses can be hard to get though that is enough reason for some people, or if it's causing you difficulties might give you access to some help/services or something but as I said I myself have not seen much of that at least in my area.
