This may be an important piece of information to communicate to the public. I think it's a pitty that the video was filmed in such a "hollywoodesque" over-dramatic fashion. However, from the content of the video, it would seem that there are a whole host of signs that something is wrong and so it is important the patients with concerns go to their GP.
The Wikipedia site looks like it has more useful information on it:
