Can't stop focusing on tiny details

[Anonymous]

I am not certain if this is the right place to post. I have a colleague who has started to focus on the tinyest details and lose sight of the big projects, and is missing deadlines and getting us all off course. Think: Spend a week reviewing a report by considering, and reconsidering the type of font rather than the contents of the report. It is annoying to work with but also so extreme I am beginning to wonder if there is a health or a mental health issue. Any insight?
