- How do you, on clinical examination in the ED/A&E, differentiate between a TIA and stroke?(6 votes)
- A TIA is a transient ischemic attack, meaning that the symptoms are NOT permanent. A stroke, however, leaves a person with PERMANENT damage. The symptoms can be similar for both TIAs and strokes, in that a person may present to the ER with facial droop and numbness/tingling/weakness bilaterally or generally. However, if the symptoms resolve after some time, then the person did not have a stroke, but, rather, a TIA. There is also a stroke scale that is used to measure how severe the event is/was.(3 votes)
- Are TIA's categorized by symptoms disappearing by 24 hours or by blood flow being restored by 24 hours? Doesn't infarction occur around 4 minutes without oxygen? wouldn't the damage then be irreversible and therefore lead to symptoms being unresolved?(5 votes)
- Yes, TIA symptoms end within 24 hours or less. That is before permanent damage is done.(2 votes)
- In my understating from video is that these FAST symptoms appear after neurons did not get enough blood and dies, which eventually affects the functionality. is there way to find out if clotting is happening in the blood supply to brain before it becomes stroke?(4 votes)
- What's the most common age range for strokes?(3 votes)
- About two thirds of strokes happen in people over 65 years old. While it is less common in people younger, it still happens(2 votes)
- So I know how to tell if someone is having a stroke, but is there a more obvious thing that might make me suspect that they are having a stroke? I mean will they act completely strange and I will understand that something has happened, or do I just constantly check with every person I know to make sure they are not having a stroke?(2 votes)
- FAST - facial asymmetry, arm weakness, slurred speech, time/tongue
You'll recognize it when you see it.(2 votes)
- how do we differentiate ? between block caused by blood clot and caused by atherosclerosis plaque ?
do we still use same therapy ( aspirin + TPA) for blocked pathway for both of them ?(2 votes)
- so I had a Hemorrhagic stroke in the ponds regen but had non of the above symptoms. if it happens again how can I tell(1 vote)
- [Voiceover] How do you know if someone is having a stroke? What are some of the common symptoms and signs that you might want to look out for? Well, there's something called the FAST test that might help you to remember the most common symptoms and signs of a stroke. So FAST, what does this mean? Well, for starters, it's a mnemonic. So we'll sort of delve into each of these letters in a minute. But it's also a bit of a reference to the need to diagnose strokes really quickly so that they can in turn be treated quickly, because, remember, the longer that treatment is delayed, the longer the person is losing neurons if they're actually having a stroke. And let me put it to you this way. For every minute that blood flow isn't restored to the brain, the person will lose about 2 million neurons. Wow, that is a lot of neurons. So, FAST, not just a mnemonic. And let's actually just jump right in here. So, again, you want a quick, easy way to tell if someone's having a stroke. So you can start by having a look for these common signs and symptoms. So we'll start with the F. The F means Face. Often a person having a stroke won't be able to control their facial muscles as normal. And they might actually develop drooping of their mouth on one side. So you can look at their face and check for any asymmetry. And actually, a good way to bring this out is to ask the person to smile. So they'll try to smile, hopefully. And it might make it easier to look for any drooping on one side. The A stands for Arm. So, for example, since strokes can cause weakness in your limbs, either on one side or on both sides of your body, it's a nice, easy little test to check if the person can raise both their arms. So if there's some difficulty or inability in raising one or both of their arms, then that might suggest a stroke has occurred. Now, the S, the S stands for Speech. And strokes can actually affect areas in the brain responsible for producing speech and understanding speech as well. So the person may have slurred speech or they may not really be able to understand what you're saying to them. So try to get the person talking to see if there are any speech problems. S for Speech. And T is for Time. So we kind of alluded to this earlier because in situations of suspected strokes, which are actually medical emergencies, time is really critical. So if you see any of these signs above, the ones that we sort of just talked about, the person would need to be taken to a hospital right away. So just to clarify what I just mentioned, actually, the first three bits of the mnemonic in particular, these aren't the only symptoms of stroke. They're just some of the more common ones that let you do a pretty quick check to see if someone might be having a stroke. And two last things before we finish up here. So the first thing, you can get more than one of these symptoms happening at one time. And you often actually develop these in combination. So for example, you might get the facial weakness and difficulty speaking and trouble moving your limbs all at once or you might get two of them or you might get all of them plus other symptoms. These are just some of the more common symptoms. And they can happen in combination or not. And the second thing is, well, we want to know how long these symptoms last, right. And it kinda depends on what's happening with the cerebral blood supply, right, 'cause, remember, a stroke is an interruption in your cerebral blood supply, the blood supply to your brain that is severe enough that it actually causes damage to your brain, right. And the other thing is remember that TIAs and strokes can have the same initial symptoms. So by knowing how long the symptoms have lasted, that'll sort of help to tease out whether it's a TIA or a stroke that's going on. And so to further clarify, if without treatment the symptoms go away within about 24 hours, then that generally means that the blood flow to that blocked off area of brain has been restored within 24 hours, which by definition means that a TIA, a transient ischemic attack, has happened and ergo, that's what caused the transient symptoms. So the symptoms will eventually go away when the blood flow is restored within 24 hours, if it's a TIA. On the other hand, if the blood flow isn't restored within 24 hours, then by definition a stroke has occurred. And then the symptoms would last longer than 24 hours and they may start to resolve after treatment. So there's a quick way to assess if someone might be having a stroke, the FAST assessment. And just as a reminder, if you do notice these symptoms, then the person needs to be taken to a hospital right away.
