"Better" in the sense implied by the poster, as in ASC is lifelong, whether or not its effects are mitigated. I am aware of how strategies can improve social interactions.
Autism* is not something that can be got "better." It is a lifelong, developmental disability. Treatment and support may be beneficial, but the person will always have ASC.
