How do I handle a long gap on my résumé? after 9 years as an accountant

My résumé shows a gap from a layoff and some health issues. This is my first time dealing with any of this. I have done some volunteering and a course during that time. What do you say in interviews?

A short, honest line such as 'family caregiving' is enough for most employers. They mostly want to know you are ready now.
