What is a Stroke? Animated Explanation Video


Hello, in this HealthSketch we want to
talk to you about stroke. It’s a bit of an odd name, stroke. It certainly has nothing to do with tennis strokes, swimming strokes or brush strokes. The word stroke comes from the idea receiving a ‘strike’ or ‘blow’ as that is how quickly strokes appear – all
of a sudden people are struck by this illness. Did you know that every year more than 15 million people worldwide have a stroke? Of these, five million die and another
five million are left disabled. Whilst most strokes occur in people over the age of 65 they can occur in much younger people too. But what exactly is a stroke? The brain, like all parts of the body,
needs oxygen, which it gets from the blood. A stroke happens when blood flow to the brain is cut off. When brain cells are starved of oxygen, they become damaged, and the symptoms that follow are called a stroke. As the brain controls the whole body, the
symptoms of a stroke can be wide-ranging, depending on which parts of the brain are
affected. If the stroke occurs here, it would cause a drooping face, here, weakness in the arms or legs, or here, difficulty speaking. Other symptoms can happen too, like changes to vision, loss of balance, confusion and memory loss. The effects might be barely noticeable, but are more often severe and disabling. Sometimes these changes can be reversed if treatment is started early. That’s why it is so important to act
quickly if you suspect a stroke. Remember, you need to get help ‘FAST’. F is for Face: is their face drooping on one side? Can they smile? A is for Arms: is there weakness in the arms? Can they lift them both up? S is for Speech: is their speech slurred? T is for Time: if you spot any one of these signs then it’s time to call an ambulance. Once the ambulance arrives at the
hospital, a doctor will assess you and arrange an urgent scan of the head, which shows where the brain is damaged and what type of stroke has happened. Strokes are put into two
groups depending on the problem in the blood vessels supplying the brain. There can either be a blockage (called an ischaemic stroke), or a bleed (called a haemorrhagic stroke). The majority of strokes are blockages. It’s
important to identify early on which sort of stroke has happened, as they each have very different treatments. Blockage strokes are commonly caused by the build-up of fatty material in blood vessels. This fatty build-up may lead to a clot
which blocks the blood supply, just like in a heart attack. This is why a stroke can be thought of as a ‘brain attack’. A clot may occur within the brain or it can travel from another part of the body, commonly the blood vessels in the neck. Clots can also travel from the heart, which may happen when you have an irregular heartbeat called ‘atrial fibrillation’, or A.F. If a blockage stroke is detected
within the first few hours, a ‘clot-busting’ medication is sometimes
given to dissolve the clot; this is called ‘thrombolysis’. If thrombolysis can’t be used, other medications, such as aspirin, will be given as treatment instead. Bleeding strokes happen when a blood
vessel bursts suddenly, causing blood to leak in or around the
brain. In these strokes, blood on the brain can lead to swelling; a serious problem which may require surgery in some cases. Sometimes, stroke symptoms completely disappear in less than 24 hours. This is called a mini-stroke or T.I.A. Often, symptoms only last a few minutes, but just like with a full-blown stroke
you must go to hospital immediately if you suspect a T.I.A. This is because a T.I.A is a warning
sign that you are at high risk of having a full stroke. Whether you have a T.I.A or a full stroke, daily medications are started and continued lifelong to help prevent further episodes. The effects of a stroke can be disabling, but given time, the brain can slowly
adapt to recover some previously lost abilities. This is why stroke rehabilitation is so
important. Rehab can be challenging, but many
specialists are on hand to help alongside doctors and nurses If you stroke causes difficulty
swallowing, dieticians can recommend special diets
or feeding tubes. If you have problems with communication,
speech and language therapists can help. If it has become difficult to walk or
perform daily tasks, physiotherapists and occupational
therapists can offer exercises and home adaptations. Also, after a stroke people often feel low or frustrated that they can’t do the things they used to, and don’t like being dependent on others. Counsellors can help talk through these feelings and many patient groups are available for further support. We’ve talked a lot about strokes, but
what can we do to prevent them from happening? Even if you’ve already had a stroke in
the past, there are many small steps we can all take to reduce our future risk of having a stroke, such as: lowering high blood pressure (the
number one cause a stroke) stopping smoking lowering cholesterol being more active eating healthily lowering alcohol intake to within
recommended limits if you have diabetes, keeping good control of blood sugar levels. In this HealthSketch we’ve talked about
what a stroke is, how to spot the key symptoms and the
need to act ‘FAST’. We’ve also talked about treatments, rehab
and the steps we can take to prevent strokes. We hope this HealthSketch about stroke has been helpful for you and those around you. HealthSketch – ‘Health for all to see’.

  1. Hi! It's stroke survivor Aaron Avila. Here's my story https://stroketv.blogspot.com/p/a.html I wanted to pause what I'm doing to say thank you for producing what I would say is the best explanation of what a stroke is I've seen to date! BRAVO! I'll be sharing throughout my stroke community! Again, Thank you, your bro Aaron.

  2. My grandma just had a mini stroke this morning and might have had another one. I'm really scared. I'm scared of losing her and I'm only 13. She's been getting sick the past few months and almost completely gave up. One time I visited her and she started talking to me about how she loves me and my brothers and she doesn't know how much longer she can take it. She's only 72. I'm so scared

  3. Not sure where this video is from, but in the UK speech and language therapists deal with swallowing / modified diet and fluids – dieticians work with us to monitor intake and balance and weight mgmt – but slt's do more than just communication

  4. My tia’s come sometimes two or three times, any time day or night each day, almost every day.Even while Im sleeping, when it wakes me up. Im living in thailand Im 80 yo.and dont have the funds for private medical care. The local general hospital waiting rooms have hundreds of waiting patients. I was given keppra 500mg. It did nothing for me. So Ive given up hope of medical care. When I have a attack building, first my vision goes haywire, then I get a woozy feeling, as though Im going to fall over, then from nowhere a terrible fear takes over. This I get any day or night. Im sometimes afraid to go to bed, as the fear attacks are frightening enough to frighten me. I once had a ischemic stroke sitting at a dining table in a hotel with my wife. Three months ago,I felt terribly tired and decided to just have a nap. I came to, with my wifes arm round my shoulders , she was fanning my face and talking to me. It was her voice I heard first. She said I had had a seizure. I couldnt believe her. I felt no different to normal. On arriving home. We went to a local herbal specialist who had had a stroke and her face had drooped. She recommended the same liquid for me, as she had used to actually recover her facial normality . It targets the blood vessels in the brain. It actually orks and keeps my symptoms at bay. It cured her after just two bottles. But if I give up for more than 24 hours, the symptoms come roaring back in. So currently, Im trapped to using this medicament until I can find a cure or something less expensive hat holds the nightmares at bay. I have sent away for some red fermented rice capsules in the hope that their effects might reduce the restrictions of blood flow in my brain. Otherwise will baby aspirin work. To take on a regular basis. Though I do want to try to reduce the restrictions, e, open them up to normal, again if possible. My fear is, Im going to have a stroke when Im on my own sometime. And only be discovered when its too late. In the vent Im unconcious, is there anything my wife can do for me to bring me round. And then what should be done. Any answers or ideas will be greatly appreciated. Regards. Mick.
