How do you deal with student burn-out, meaning that there is too much outside and personal issues in their life that they can not cope?

How do you reach a student that is so preoccupied with their home life that school and school related activities become less important

There are times when students come to you with personal issues totally unrelated to school. I have always done my best to help the student to be solution oriented not problem focused. I would never turn a student away telling them, "that is not my problem" but I am not sure how involved I should become?
