with Luke Perry, the “Beverly hills 90210” and “Riverdale” actor hospitalized after the 52-year-old reportedly suffered a massive stroke. Paula Faris joins us now with more. Good morning, Paula. Good morning. There were early reports that he was in a medically induced coma which his spokesperson quickly and emphatically denied. What we do know is that Perry is at an L.A. Area hospital. He is under observation and being monitored very closely. Let me tell you something just so you know in advance, I’m not in a good mood today. Reporter: You may kw him best as ’90s teen hearttlob Dylan Mckay from “Beverly hills 90210” but Luke Perry is hospitalized after reportedly suffering a stroke at his home in Los Angeles. The Los Angeles fire department responding to the actor’s home on Thursday morning with dispatch audio referring to a stroke patient. Unit 102, rescue 78 stroke. Reporter: A rep for Perry tells us that Luke Perry is currently under observation at the hospital. These days Perry stars as Fred Andrews on the cw series “Riverdale” where his character was shot and hospitalized but pulled through. Dad, dad. Can you hear me? Reporter: Strokes are a leading cause of disability in the U.S. And occur when there is a sudden interruption in the blood supply to the brain but can also happen when a blood vessel ruptures and can affect anyone but are most common among the elderly. The 52-year-old’s hospitalization comes on the same day that a “90210” reboot was announced starring most of the original cast. But not Perry who was busy shooting “Riverdale” and there’s been an outpouring of support from well-wishers on Instagram including Perry’s former “90210” co-stars shannen Doherty who posted this old photo of the two and Ian ziering who wries no words can express what my heart feels hearing today’s shocking news. Let us all say a prayer for his speedy recovery. Most of Perry’s former “90210” co-stars have signed on for that reboot but we’ve learned Perry did not because of his commitments to “Riverdale” which was recently renewed for a fifth season. Our prayers for a speedy recovery. Joining us now is Dr. Jennifer Ashton and, doc, such a young guy. When you hear the word stroke what’s the first thing that comes to mind. We have to remember that is unconfirmed when we’re talking specifically about Luke Perry but a good opportunity to talk about stroke which is a leading cause of death in the U.S. First of all the first thing that comes to mind is where in the brain is the actual stroke, how large of an area is affected and what type. We heard in Paula’s piece two basic types one caused by hemorrhage seen with uncontrolled high blood pressure and the other type caused by a clot. If you look at this animation, Michael, you can really see how devastating this is. If a clot breaks loose from an artery, lodges in a tiny, tiny vessel of the brain, all of 9 brain area that’s then supplied downstream of that clot is affected. It’s exactly the same physiology as a heart attack and when you’re talking about the brain this is an incredibly unforgiving organ for any type of disruption for blood supply. What are the symptoms of a stroke? This is what I think can be truly life saving. Stroke is a critical situation where every second matters. You remember it by F.A.S.T. Facial droop, arm weakness, slurred speech or difficulty speaking and the “T” stands for time to call 911 because every minute, every hour matters. Every second counts. What about recovery. Depends on age of the patient, how large the stroke is, where in the brain it’s loeshted. Younger patients tend to have a harder prognosis because there’s not that swelling that occurs in the brain as we age and that lack of swelling space actually makes it harder for the brain to accommodate a stroke but the key is prompt treatment. To reinforce even in the reports of Luke Perry, he was conscious and talking at the beginning. If you notice any of those symptoms make the phone call. Every hospital has a stroke team and we activate it just like a cardiac arrest because time is of the essence. All right, doc. Certainly wishing him well.
