Let's count the ways: New stroke, tia, cardiac arrhythmia, drug overdosage, dehydration and hypotension, seizure? Sounds like there was a loss of consciousness. If there was an arrhythmia she might need cardiac monitoring. If a new onset of seizure we have to r/o brain mass or metabolic abnormalities. Tia warrants other evaluations since it might be a harbinger of a full blown stroke.
