Jay Z & Kanye West -- Music Video Warning SAVED LIVES ... Says Epilepsy Org.

It seems cray ... but a simple warning that Jay Z and Kanye West included at the top of their "N**gas in Paris" video may have been the difference between life and death for some of their seizure-prone fans ... this according to multiple epilepsy organizations.

The concern is obvious ... since the video is filled with strobe lights and quick edits. The warning at the top of the video reads, "This video has been identified by Epilepsy Action to potentially trigger seizures for people with photosensitive epilepsy. Viewer discretion is advised."

Now, the Citizens United for Research in Epilepsy tell TMZ ... "50,000 individuals lose their lives each year due to seizures and related causes. We applaud artists like Kanye West and Jay Z who recognize the potential dangers in their videos, movies and performances and are conscientious enough to warn patients and their families about the risks."

And CURE isn't alone in their praise ... a rep for the Epilepsy Therapy Project tells us the organization "appreciates the sensitivities that Kanye and Jay Z showed in appropriately warning individuals with photosensitive epilepsy that their video may cause seizures."

The rep adds, "Given the 4 million people who suffer from epilepsy in the US alone, we need to work together with the music industry on how best to destigmatize the condition and stop seizures and epilepsy once and for all so everyone can enjoy the music."
