I am a professor at a liberal arts college and I get 'silent' or visual migraines that impair my vision. Yesterday, I was fortunate that my migraine began after my lecture and not during. With the visual impairment, I can't read properly but feel no headache symptoms. This becomes very challenging when dealing with students who hand you forms to sign, not to mention reading my powerpoint lectures. So far, I have never had a migraine during lecture but am terrified of it! How have other teachers/educators managed the onset of a migraine during class?
First of all, this is
technically a migraine, without the pain. This is according to my ophthalmologist. Yes, the vision disturbances are referred to as a migraine aura, but it's still part of a migraine, just as the pain is part of a migraine. You can have a migraine with pain, a migraine with aura, or a migraine with both. I've had all of the above.
I taught college-level physics and math for 12 years. This is the first spring semester I have not taught a class. I had to turn down my spring assignment because of severe health problems, so maybe I'm not the best to advise you on coping mechanisms, but I do suffer from vision issues, neurological problems: vertical double vision and blurry vision that gets better or worse unpredictably.
Here are my tricks, such as they are....before class I would come up with an in-class assignment to give them if I became too ill to continue lecturing. Also, I would give them "extra credit" for working out problems on the board, for example when I returned their exams and I was having trouble reading the tests or having vertigo or whatever.
Depending on what you teach, these may or may not work for you.
