what I have seen is something like
"Resolution or management of Family Issues 2017-2018"
People know that things happen in our personal lives that we need to take care of and sometimes it means a gap in our career. If during an interview, an inexperienced interviewer inappropriately asks what family issue was going on, I would answer, "it was a personal matter that I would rather not talk about". And leave it at that. I use family issue rather than personal issue because it is much broader and different people will interpret that differently, which would be what I want if I am in that situation.
