An isolated aura of transient weakness or numbness without any subsequent headache may lead to tens of thousands of dollars wasted on diagnostic tests for stroke— and quite possibly to unnecessary medications and procedures.

--- Does it say "an isolated aura as a result of temporary weakness or numbness ..." ? It's about aura that appears during the migraine headache.


I don't think so. I think it means that the aura itself consists of numbness or weakness that goes away quickly.
