Good evening sir!
The good news is that mental health issues are not seen as almost a "crime" as they used to be some decades ago. I would strongly suggest that she sees her doctor soon, mainly to help alleviate her problems possibly with medication, but also so that this event is recorded in her medical history, so that she can then ask for perhaps a [short?] leave of absence from uni and/or extra time for assignments/homework as well as possibly for exams depending on the nature of the MH issues.
She should, I would advise, also see her personal tutor to discuss matters and whoever deals with facilities/help with extenuating circumstances [usually one of the lecturers in her dept] to secure the aid outlined above.
Now that MH problems do not carry a stigma as they used to, my view is that "disciplinaries" should not come into the equation at all, as long as she is honest about her health, and is prepared to undertake appropriate measures to help sort it as advised by the professionals.
I wish you the best of luck in this, I am sure, v tough time for you and your family.
