1
- My name is Dr. Khawaja.
2
I'm a stroke neurologist at Cleveland Clinic, and I specialize in treating strokes and cerebrovascular disease at Cleveland Clinic.
3
So a stroke is a medical emergency, and it happens when blood flow to the brain stops.
4
And when that happens, it can cause all different types of symptoms.
5
It can affect someone's speech, language, vision, balance, strength, sensation.
6
There are two main types of strokes: one is ischemic and the other is hemorrhagic.
7
And ischemic stroke is far more common and occurs when blood flow to the brain is interrupted by a clot or occlusion.
8
And when that happens, the effected part of the brain that doesn't receive blood flow basically stops working.
9
The other type of stroke is hemorrhagic, and that occurs when an artery in the brain basically bursts.
10
And that causes bleeding in and around the brain.
11
And the brain does not like any kind of blood that's not in the arteries.
12
It can cause irritation.
13
There are modifiable risk factors, and then there's non-modifiable risk factors.
14
So things that we can't necessarily change: our age, our genetics, and then our gender.
15
We know that at certain ages men have a higher risk of stroke.
16
And then women can have a higher risk of stroke.
17
Then there are the modifiable risk factors: things such as high blood pressure, high cholesterol, diabetes, obesity, atrial fibrillation, smoking, alcohol use.
18
Some of the most common cause of stroke include things such as high blood pressure, which is often referred to as the silent killer.
19
People don't know they have high blood pressure.
20
And really the only way to know is if it's checked, either at home by yourself or when you go to your doctor's office.
21
Atrial fibrillation is also something that sometimes we discover only when patients have a stroke, and that's an irregular heart rhythm.
22
Some people will feel palpitations or kind of a racing of the heart.
23
A major risk factor is also smoking.
24
And so stopping smoking can significantly reduce the risk of stroke.
25
When a stroke happens, it is of the upmost importance to get evaluated in an emergency room to receive lifesaving and disability-sparing treatments.
26
It is better to call 911 than to try to drive it to the ER yourself, if time permits, and get evaluated because there are certain medications and certain procedures that we can do.
27
But those medications and procedures are all time-based, and they work better if we're able to get to people sooner.
28
One of those major treatments is Alteplase, and the other treatment is endovascular therapy.
29
With Alteplase or Tenecteplase, these are medicines that we're able to give through the IV that break up clots.
30
I like to think of it as Drano for the body.
31
We're able to inject it, and it finds the clots and it breaks them up.
32
And it's been shown to improve outcomes.
33
Endovascular therapy, it's like kind of snaking a drain, where you take a catheter and you move it all the way up into the brain and you pull a clot out.
34
And that treatment has been shown to be extremely effective in reducing disability related to stroke.
35
Stroke is very preventable.
36
And one of the easiest ways to prevent a stroke is to know what your risk factors are and live a healthy lifestyle.
37
We're noting that more and more young people are having strokes every year.
38
And it's something that is no longer a disease of the elderly, that we're seeing patients in their 20s, 30s, 40s.
39
Even children, unfortunately, can have strokes.
40
And so it's very important to ensure that you have regular follow-up, annual visits with your physician, just to make sure that everything is on track.
41
And then if you do have risk factors, to make sure that you are actively managing it.
42
So it's important for you to be active in your own care.
43
You yourself are also managing your blood pressure, and you yourself are taking steps to ensure that everything is well controlled.
44
And not only that, the pills alone really don't help unless you're also living a healthy lifestyle.
45
So eating right, exercising regularly, and also kind of tracking your weight to make sure that your weight is within the target.

Por que praticar a fala com este vídeo?

Praticar a fala utilizando o vídeo "The Best Ways to Prevent a Stroke" oferece uma excelente oportunidade para expandir seu vocabulário e aprimorar a capacidade de comunicação em inglês. Através do shadowing em inglês, você pode repetir as falas do Dr. Khawaja, o que ajuda a internalizar estruturas gramaticais e a melhorar a fluência. Essa técnica, conhecida como shadowspeak, envolve ouvir e reproduzir o que é dito em tempo real, favorecendo a memorização e a prontidão na fala. Além disso, ao discutir temas relacionados à saúde, você também se familiariza com um vocabulário importante e técnico que pode ser útil em diversas situações de conversação.

Gramática & Expressões em Contexto

No discurso do Dr. Khawaja, podemos observar várias estruturas gramaticais e expressões que são úteis para quem deseja melhorar a fala em inglês. Aqui estão algumas delas:

  • "It happens when blood flow to the brain stops." - Aqui, a estrutura "It happens when..." é uma maneira eficaz de introduzir cenários e resultados.
  • "There are two main types of strokes: ischemic and hemorrhagic." - A dualidade apresentada através de "There are...:..." proporciona uma forma clara de categorizar informações.
  • "High blood pressure is often referred to as the silent killer." - Essa expressão é uma boa maneira de descrever algo que pode ser perigoso, mas silencioso, ajudando a enriquecer o vocabulário descritivo.

Praticar essas estruturas em voz alta, especialmente com a ajuda de shadow speak, pode ajudar a reforçar sua compreensão e aplicação em conversas cotidianas.

Armadilhas Comuns de Pronúncia

Ao ouvir o vídeo, alguns termos e frases podem apresentar desafios de pronúncia para falantes não nativos. Aqui estão alguns deles:

  • "Atrial fibrillation" - Esta expressão pode ser difícil por suas sílabas numerosas. Pratique a divisão em partes: "A-trial fi-bril-la-tion."
  • "Hemorrhagic" - A pronúncia correta é vital, e a sílaba tônica está na segunda parte: "he-mo-RRAG-ic."
  • "Disability-sparing treatments" - A velocidade e a fluidez ao pronunciar podem causar confusão. Pratique separar as palavras para garantir clareza.

Utilizar técnicas de melhorar a pronúncia em inglês ajudará na superação dessas armadilhas. O shadowspeak é uma forma eficaz de praticar esses sons desafiadores, permitindo que você se sinta mais confortável e confiante em sua fala.

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
