Effectively, I think it can be squashed. If caused by external stimuli, and the stimuli are no longer present, I can see the problem being only a memory. Not to mention, there can be emplaced a level of immunity: In knowing the problem can potentially be solved, the resulting confidence can make one more resilient. It's less likely to even become a "problem" in the future.If neurosis then begins - and ends - within the individual, is it ever truly vacated? Does awareness of the neurotic tendency forever chain it to one's psychological identity?
