1
Stroke is the second most common cause of death worldwide and is a leading cause of permanent disability.
2
Hello, I am Dr. Sandeep Bharathoki and I am interventional neuroradiologist.
3
Today we are going to talk about acute stroke,
4
symptoms caused by stroke and its prevention.
5
Stroke is also known as brain attack similar to heart attack.
6
We define stroke as sudden onset of focal neurological deficit,
7
focal loss of brain function due to disruption of blood supply of the brain.
8
And most commonly stroke happen due to a blood clot blocking the blood supply of the brain.
9
This kind of stroke is known as ischemic stroke.
10
Another form of stroke is
11
when one of the artery in the brain rupture causing the brain hemorrhage and this is known as hemorrhagic stroke.
12
It is very important to identify the symptoms of a stroke
13
because it is possible that we can remove this blood clot causing the stroke
14
if the patient arrives to the hospital within the therapeutic window period of 6 hours.
15
To understand more about the stroke and symptoms caused by stroke,
16
let us see this human brain model.
17
So this is the plastic model of human brain and this brain is divided into left hemisphere and the right hemisphere.
18
And here we could see that each part of the cerebral hemisphere is divided into multiple lobes.
19
The front side is the frontal lobe,
20
behind the frontal lobe is the parietal lobe,
21
and at the end is the occipital lobe,
22
and this part is the temporal lobe.
23
So each part of the brain has a different function,
24
and we can imagine this as cabinets with different things within the cabinets.
25
We could consider the front part of the brain as a CEO of the brain,
26
which plan and execute the motor function.
27
For example, if we want to go for a shopping or we want to cook a meal,
28
frontal lobe will plan and execute the correct order of motor function to achieve that.
29
Behind this area is the motor cortex.
30
So this is the motor cortex and which controls the motor function of upper and lower limb,
31
especially the learned skill movements.
32
and behind this motor cortex is the sensory cortex and this is responsible for the touch sensation.
33
Normally, the right side of the brain controls the left side of the body part
34
and the language function is exclusively located at the left cerebral hemisphere.
35
So, when a clot occludes one of the brain artery,
36
the part of that brain will die within minutes due to lack of oxygen,
37
glucose and other nutrients.
38
So, if the stroke involves the motor cortex on the right side here in this artery,
39
then this part of the brain will die within minutes
40
and will manifest as a loss of motor function and weakness on the left side of the upper limb and lower limb.
41
And these symptoms occur suddenly and involve one side of the body parts.
42
Simplest way to recognize the signs and symptoms of a stroke is to remember the mnemonic BE FAST.
43
BE stands for balance.
44
If someone suddenly feel sudden onset of dizziness,
45
instability, this could be a sign of stroke then e stands for eye symptoms
46
so somebody is feeling a sudden loss of vision loss on one side of the eye visual blurring double vision
47
or as
48
if there is a curtain pulled out in front of one
49
of the eye then f stands for face ask the patient to smile
50
if the smile is uneven
51
if there is a drooling of face on one side of the face it could be a sign of early stroke
52
A for arm weakness, ask the patient to lift both the arms and if there is drifting of one of the arm,
53
if there is heaviness feeling or weakness on one side of the arm,
54
then this could be a sign of a stroke.
55
S for speech, if there is a speech difficulty,
56
unable to speak or slurring of speech or unable to understand the speech,
57
this could be a sign of stroke.
58
And finally, the T, T stands for time to call ambulance.
59
So don't wait, don't hesitate,
60
call immediately the ambulance
61
and reach out to the stroke center every minute delay cause about 1.9 million neuron loss
62
so don't delay to reach out to the stroke center stroke is preventable condition
63
and is treatable condition it can be prevented in more than 90 of the patients by adopting the healthy lifestyle
64
it's very important to know the risk factor for the stroke
65
the most important risk factor for the stroke is high blood
66
pressure other risk factors are diabetes high cholesterol smoking alcohol obesity lack of exercise
67
so it's very important to know all these risk factors
68
and adopt the healthy lifestyle to prevent the stroke from happening
69
it is recommended to keep the blood pressure below 130 by
70
80 millimeter mercury it is recommended to do regular exercise at
71
least 40 minutes of vigorous exercise three to four times in
72
a week it is advised to take a mediterranean diet rich in fruits
73
and vegetables and dry fruits
74
and olive oil the consumption of fish at least once in
75
a week reduce the chance of stroke by 50 percent it's
76
very important to remember the early signs of a stroke to remember the mnemonic be fast and to adopt the healthy lifestyle.

이번 수업에 대해

이번 수업에서는 뇌졸중의 증상과 예방에 대해 이야기합니다. 뇌졸중은 전 세계적으로 두 번째로 흔한 사망 원인이며, 영구적인 장애를 유발하는 주요 원인 중 하나입니다. 이 수업을 통해 뇌졸중의 다양한 유형과 신체에 미치는 영향을 이해하고, 이를 조기에 인식하는 방법을 익힐 수 있습니다. 뇌졸중의 증상들을 알고 있으면 적절한 조치를 통해 생명을 구할 수 있는 기회를 높일 수 있습니다. 이러한 내용은 '영어 회화 연습'에 도움이 되는 중요한 주제입니다.

주요 어휘 및 구문

  • Stroke (뇌졸중): 갑작스러운 뇌 기능의 결핍을 의미합니다.
  • Ischemic stroke (허혈성 뇌졸중): 혈전으로 혈액 공급이 차단될 때 발생합니다.
  • Hemorrhagic stroke (출혈성 뇌졸중): 뇌의 혈관이 터져 생기는 뇌출혈입니다.
  • Symptoms (증상): 뇌졸중과 관련된 신체 변화나 고통을 의미합니다.
  • Balance (균형): 뇌졸중의 증상 중 하나로, 갑작스러운 어지러움을 의미합니다.
  • Motor function (운동 기능): 신체의 움직임을 조절하는 뇌의 기능입니다.
  • Therapeutic window (치료 창): 뇌졸중 치료를 위한 최적의 시간대입니다.
  • BE FAST (신속 인식): 뇌졸중 증상을 인식하기 위한 방법의 약자입니다.

연습 팁

이번 영상은 뇌졸중과 관련하여 중요한 정보를 제공하며, 언어적 표현을 연습하기에 적합합니다. 영어 쉐도잉을 통해 성공적인 학습을 위해 몇 가지 팁을 제안합니다:

  • 영상 속의 원어민 스피치의 속도를 잘 파악하여 따라 해보세요. 천천히 따라하고 익숙해지면 점진적으로 속도를 높여보세요.
  • 자주 생소한 단어와 구문을 반복적으로 연습하세요. ‘shadowing site’에서 연습한 내용을 바탕으로 사용해보세요.
  • 중요한 어휘와 표현을 직접 사용해보며, 자신의 목소리로 발음해보세요. shadowspeak을 이용해 연습하면 많은 도움이 될 것입니다.
  • BE FAST와 같은 유용한 구문을 기억하고 뇌졸중의 증상을 설명할 수 있도록 연습하세요. 이를 통해 대화 중에 활용할 수 있는 언어적 유창성을 키울 수 있습니다.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
