Some one close to me has twice been diagnosed as suffering from a "thunderclap event". That is the term that was used to describe them by the medical professionals. Nothing showed up on any scans, symptoms were similar to a stroke, head pain/collapse/unconscious etc, no apparent longer symptoms as uninjured during the event. Google search doesn't reveal much so far as cause but could be stress related.
