What is prez?
2739137 posted:
My husband was diagnosed with prez (may not be correct spelling) of the brain after a seizure caused by extremely high blood pressure. I can't find a definition for this can anyone help?
Caprice_WebMD_Staff responded:
Hi 2739137 and welcome to WebMD,

PRES (not Prez) stands for Posterior Reversible Encephalopathy Syndrome. It is also called "Hypertensive Encephalopathy." In our article on "High Blood Pressure and Hypertensive Crisis ," it mentions "Changes in mental status, such as confusion or coma ( encephalopathy)."

I hope this helps. Your husband's doctor should be able to tell you more.

P.S. Thanks to my fellow moderator, Byroney, for tracking down this information for me. :-)
2739137 replied to Caprice_WebMD_Staff's response:
Thank you for the information. Would this condition ever require use of anti-seizure medication such as dilantin?
Caprice_WebMD_Staff replied to 2739137's response:
According to this WebMD information :

"This drug may also be used to treat certain types of irregular heartbeats."

But many medications end up being used for conditions other than what they were originally developed and approved for.
