Sometimes I have done with my husband if it's relevant to recognising and dealing with a long term problem.

Dealing with specific episodes of ADHD inattentiveness was part of getting real about it, coming out of denial. They were literally life threatening - far too many near-misses and extremely expensive accidents. Once the facts were admitted, he sought help and finally got it.
