Udar mózgu
Objawy
Udar mózgu, zarówno niedokrwienny, jak i krwotoczny, stanowi nagłe zagrożenie życia wymagające pilnej interwencji medycznej. Objawy obejmują jednostronne osłabienie lub paraliż twarzy, kończyn, zaburzenia mowy i widzenia oraz nagły, silny ból głowy (szczególnie w udarze krwotocznym). System FAST (Face, Arm, Speech, Time) ułatwia szybką identyfikację objawów i podkreśla konieczność natychmiastowego wezwania pomocy (999/911/112). Udar lewej półkuli powoduje deficyty po stronie prawej, w tym afazję, natomiast udar prawej półkuli objawia się deficytami po stronie lewej oraz zaburzeniami przestrzennymi. Progresja neurologiczna w ciągu 48-72 godzin dotyczy około 15% pacjentów z udarem niedokrwiennym, szczególnie u osób z zaawansowaną miażdżycą i chorobą niedokrwienną serca, co wiąże się z gorszym rokowaniem. Leczenie trombolityczne jest skuteczne w oknie czasowym 3-4,5 godziny od wystąpienia objawów, a każda minuta opóźnienia powoduje obumieranie około 1,9 miliona neuronów.
Objawy udaru mózgu
Udar mózgu (udar niedokrwienny lub krwotoczny) to stan nagłego zagrożenia życia, wymagający natychmiastowej interwencji medycznej. Objawia się on nagłym wystąpieniem zaburzeń neurologicznych wynikających z przerwania dopływu krwi do określonej części mózgu lub krwotoku wewnątrzczaszkowego. Każda minuta opóźnienia w udzieleniu pomocy medycznej powoduje obumieranie około 1,9 miliona komórek nerwowych mózgu, co może prowadzić do trwałych uszkodzeń i niepełnosprawności12.
Główne objawy udaru
Najczęstsze objawy udaru mózgu pojawiają się nagle i mogą obejmować12:
- Osłabienie lub paraliż twarzy, ramienia lub nogi, zwłaszcza po jednej stronie ciała
- Zaburzenia mowy – trudności w mówieniu, rozumieniu mowy, bełkotliwa mowa
- Zaburzenia widzenia – niewyraźne, podwójne widzenie lub utrata widzenia w jednym lub obu oczach
- Zawroty głowy, problemy z utrzymaniem równowagi i koordynacją ruchową
- Nagły, silny ból głowy bez znanej przyczyny (szczególnie w udarze krwotocznym)
System FAST (Face, Arm, Speech, Time – Twarz, Ramię, Mowa, Czas) to prosty sposób na rozpoznanie najczęstszych objawów udaru12:
- F (Face/Twarz): asymetria twarzy, opadnięcie kącika ust po jednej stronie
- A (Arm/Ramię): osłabienie jednej kończyny górnej, niemożność uniesienia ramienia
- S (Speech/Mowa): zaburzenia mowy, bełkotliwa mowa, trudności w formułowaniu zdań
- T (Time/Czas): natychmiast wezwij pogotowie (999/911/112) – czas jest kluczowy
Różnice objawów w zależności od lokalizacji udaru
Objawy udaru mogą różnić się w zależności od tego, która część mózgu została dotknięta12:
- Udar lewej półkuli mózgu wpływa na prawą stronę ciała i może powodować:
- Paraliż lub osłabienie prawej strony ciała
- Problemy z mową i językiem (afazja)
- Zaburzenia w myśleniu abstrakcyjnym
- Trudności z pamięcią
- Powolny, ostrożny styl zachowania
- Udar prawej półkuli mózgu wpływa na lewą stronę ciała i może powodować:
- Paraliż lub osłabienie lewej strony ciała
- Problemy z przestrzennym myśleniem
- Zaburzenia widzenia
- Problemy z pamięcią i myśleniem
- Impulsywny styl zachowania
- Udar pnia mózgu może wpływać na obie strony ciała jednocześnie i powodować:
- Problemy z podstawowymi funkcjami życiowymi (oddychanie, przełykanie, rytm serca)
- Zawroty głowy, nudności i wymioty
- W najcięższych przypadkach – stan „zamknięcia” (locked-in syndrome), gdzie pacjent jest świadomy, ale całkowicie sparaliżowany z wyjątkiem możliwości ruchu oczu12
Rozpoznawanie przejściowego ataku niedokrwiennego (TIA)
Przejściowy atak niedokrwienny (TIA), zwany również „mini-udarem”, charakteryzuje się objawami podobnymi do udaru, które ustępują w ciągu kilku minut lub godzin (zazwyczaj do 24 godzin)12. TIA jest poważnym sygnałem ostrzegawczym wskazującym na podwyższone ryzyko wystąpienia pełnoobjawowego udaru w niedalekiej przyszłości:
- Objawy TIA są identyczne jak w przypadku udaru, ale są przejściowe
- Około 1 na 5 osób, które przeszły TIA, doświadczy pełnoobjawowego udaru w ciągu 3 miesięcy1
- TIA wymaga takiego samego pilnego podejścia jak udar – należy natychmiast wezwać pomoc medyczną
Progresja objawów udaru
Objawy udaru mózgu mogą rozwijać się na różne sposoby12:
- Nagłe wystąpienie: większość udarów charakteryzuje się nagłym pojawieniem się objawów
- Stopniowe narastanie: w niektórych przypadkach objawy mogą rozwijać się stopniowo w ciągu godzin lub dni
- Fluktuacja objawów: objawy mogą czasowo się poprawiać, a następnie pogarszać
W przypadku progresującego udaru niedokrwiennego stan neurologiczny pacjenta pogarsza się w ciągu pierwszych 48-72 godzin od wystąpienia początkowych objawów12. Badania wykazały, że:
- Pogorszenie stanu neurologicznego występuje u około 15% pacjentów z udarem niedokrwiennym
- Pacjenci z zaawansowaną miażdżycą, zwłaszcza ze zwężeniem tętnicy szyjnej (50% vs 19%) i chorobą niedokrwienną serca (33% vs 6%), mają większe ryzyko progresji udaru
- Progresja udaru wiąże się z gorszym rokowaniem i wyższym ryzykiem zgonu lub niepełnosprawności w perspektywie 3 miesięcy1
Zróżnicowanie objawów w zależności od typu udaru
Objawy mogą się nieznacznie różnić w zależności od typu udaru12:
| Udar niedokrwienny | Udar krwotoczny |
|---|---|
|
|
Znaczenie szybkiej reakcji
Natychmiastowa reakcja na objawy udaru jest kluczowa dla skutecznego leczenia i zmniejszenia ryzyka trwałych uszkodzeń12:
- Skuteczne leczenie udaru niedokrwiennego jest możliwe tylko w ciągu pierwszych 3-4,5 godzin od wystąpienia objawów1
- W każdej minucie udaru obumiera około 1,9 miliona komórek nerwowych mózgu1
- Personel ratunkowy może rozpocząć leczenie jeszcze przed dotarciem do szpitala
- Pacjenci, którzy otrzymują leczenie w ciągu pierwszych 3 godzin, mają znacznie mniejszą niepełnosprawność po 3 miesiącach niż ci, którzy otrzymują opóźnioną pomoc1
Nawet jeśli objawy ustępują same, należy natychmiast wezwać pomoc medyczną, ponieważ może to wskazywać na TIA, który jest poważnym czynnikiem ryzyka wystąpienia pełnoobjawowego udaru w niedalekiej przyszłości1.
Nietypowe objawy udaru u kobiet
Kobiety mogą doświadczać dodatkowych, mniej typowych objawów udaru, które mogą być łatwiej przeoczone12:
- Ekstremalne zmęczenie
- Czkawka
- Nudności
- Przyspieszone bicie serca
- Nagły ból twarzy, ramienia lub nogi
- Dezorientacja, problemy z pamięcią
Udar jest trzecią najczęstszą przyczyną zgonów wśród kobiet i dotyka 1 na 5 kobiet1. Kobiety mają również gorszy wskaźnik jakości życia po udarze w porównaniu do mężczyzn1.
Powikłania i długotrwałe efekty udaru
Udar może prowadzić do szeregu powikłań i długotrwałych efektów, w zależności od lokalizacji i rozmiaru uszkodzeń12:
- Zaburzenia ruchowe:
- Osłabienie mięśni lub paraliż (najczęściej jednostronne)
- Spastyczność (wzmożone napięcie mięśniowe)
- Problemy z równowagą i koordynacją
- Zaburzenia poznawcze:
- Problemy z pamięcią
- Trudności z koncentracją
- Zaburzenia funkcji wykonawczych
- Zwiększone ryzyko demencji naczyniowej
- Zaburzenia komunikacji:
- Afazja (trudności z rozumieniem lub tworzeniem mowy)
- Dyzartria (zaburzenia wymowy)
- Problemy z połykaniem (dysfagia)
- Zaburzenia emocjonalne:
- Depresja poudarowa
- Labilność emocjonalna (nagłe zmiany nastroju)
- Lęk
- Inne problemy:
- Zmęczenie (bardzo częsty objaw)
- Ból, w tym centralny ból poudarowy
- Utrata kontroli nad pęcherzem i jelitami
- Zaburzenia widzenia
Proces zdrowienia i rehabilitacja
Proces powrotu do zdrowia po udarze jest indywidualny i zależy od wielu czynników12:
- Najszybszy postęp w rekonwalescencji następuje zwykle w pierwszych 3-6 miesiącach, ale poprawa może postępować przez wiele miesięcy, a nawet lat1
- Około 1/3 pacjentów po udarze odzyskuje pełną sprawność, 1/3 odzyskuje sprawność częściowo, a 1/3 nie odzyskuje utraconych funkcji1
- Około 10-20% pacjentów może nie przeżyć wczesnego okresu po udarze1
- Rehabilitacja rozpoczyna się bardzo wcześnie po udarze i może obejmować:
- Fizjoterapię
- Terapię zajęciową
- Terapię mowy
- Wsparcie psychologiczne
Istotne jest również zapobieganie kolejnym udarom, ponieważ po przebyciu pierwszego udaru ryzyko kolejnego wynosi 5-15% rocznie1. Regularne przyjmowanie przepisanych leków, kontrola czynników ryzyka i zdrowy styl życia są kluczowe dla prewencji wtórnej.
Objawy udaru u dzieci
Udar może wystąpić również u dzieci i jest jedną z 10 najczęstszych przyczyn zgonów w tej grupie wiekowej1. Objawy udaru u dzieci mogą częściowo różnić się od tych obserwowanych u dorosłych:
- Osłabienie lub drętwienie, szczególnie po jednej stronie ciała
- Trudności z mówieniem lub rozumieniem mowy
- Zaburzenia widzenia lub podwójne widzenie
- Zawroty głowy, utrata równowagi lub koordynacji
- Napady drgawkowe (częstsze u dzieci niż u dorosłych)
- Nudności i wymioty (częstsze u dzieci)
Dzieci zwykle lepiej zdrowieją po udarze niż dorośli dzięki większej plastyczności mózgu, jednak około 60% dzieci, które przeżyły udar, będzie miało trwałe problemy neurologiczne o różnym nasileniu1.

It might start with the odd symptom. Maybe the side of your face goes numb. Or you can’t lift your arm because it feels like lead. If you’re having a stroke, what happens next — and how fast — makes all the difference in how you’ll recover. […] No matter which one it is, it’s not long before brain cells start to die. Once a stroke begins, you lose almost 2 million brain cells every minute. […] Any one of those three signs — face drooping, arm weakness, and trouble talking — means someone needs to call 911. […] When the ambulance shows up, they’re going to act fast. […] Often, first responders use the Cincinnati Prehospital Stroke Scale (CPSS), where they ask you to: Smile so they can see if your face looks crooked or droops on one side; Hold both arms out straight for 10 seconds to see if one arm drifts downward or doesn’t move at all; Say a simple phrase, like „The sky is blue,” to check if you slur your words or have trouble understanding what they’re saying. […] Once you’re through the emergency room doors, the stroke team jumps into action. […] You get tests to see if you’re having a stroke and how severe it might be. […] For an ischemic stroke, that usually means you get a clot-busting drug. It works fast to get blood flowing back to your brain.

Call 911 if these warning signs of stroke are present. […] F.A.S.T. Warning Signs of Stroke: Use the letters in F.A.S.T. to spot a Stroke. […] A = Arm Weaknessâ Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward? […] S = Speech Difficultyâ Is speech slurred? […] T = Time to call 911â Stroke is an emergency. Every minute counts. Call 911 immediately. Note the time when any of the symptoms first appear. […] Other Stroke Symptoms: Watch for Sudden: NUMBNESS or weakness of face, arm, or leg, especially on one side of the body. […] CONFUSION, trouble speaking or understanding speech. […] TROUBLE SEEING in one or both eyes. […] TROUBLE WALKING, dizziness, loss of balance or coordination. […] SEVERE HEADACHE with no known cause.

- #1 Effects of Stroke | American Stroke Associationhttps://www.stroke.org/en/about-stroke/effects-of-stroke
Every stroke is unique, but strokes tend to affect people in common ways. […] If a stroke occurs and blood flow can’t reach the region that controls a particular body function, that part of the body won’t work as it should. […] How you are affected by a stroke depends primarily on the location and the extent of damage to the brain tissue. […] Brain injury can cause changes in certain sensory, motor, or cognitive functions. […] A stroke on the left side of the brain affects the right side of the body. […] A stroke on the right side of the brain affects the left side of the body. […] If the stroke occurs toward the back of the brain, it’s likely that some disability involving vision will result. […] If the stroke occurs in the left side of the brain, the right side of the body will be affected, usually producing: Paralysis on the right side of the body, Sensory changes on the right side of the body, Speech/language problems, Abstract thinking, Problems with thinking and memory, Slow, cautious behavioral style.
- #1 Effects of Stroke | American Stroke Associationhttps://www.stroke.org/en/about-stroke/effects-of-stroke
If the stroke occurs in the right side of the brain, the left side of the body will be affected, usually producing: Paralysis on the left side of the body, Sensory changes on the left side of the body, Vision problems, Spatial thinking or imagery, Problems with thinking and memory, Quick, inquisitive behavioral style. […] When stroke occurs in the brain stem, it can affect both sides of the body. […] The most severe damage could leave someone in a âlocked-inâ state. […] Locked-in state is a condition in which the patient is generally unable to speak and can’t move because of the paralysis of muscles except for vertical eye movements and blinking. […] The person remains conscious, they can hear, think, reason and comprehend. […] Communication is established through eye movements.
- #1 Stroke: What It Is, Causes, Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/5601-stroke
Hemorrhagic strokes happen when a blood vessel in your brain breaks or tears (ruptures). […] A transient ischemic attack (TIA) sometimes called a mini-stroke is like a stroke, but the effects are temporary. These are often warning signs that a person has a very high risk of having a true stroke soon. […] Most people take a few months to recover after a stroke. Your provider will tell you what to expect. They’ll help you set recovery goals and expectations that fit your unique health and situation. […] Call 911 (or your local emergency services number) if you think you’re experiencing stroke symptoms again. Another stroke has an even higher risk of causing severe complications and being fatal.

If you or someone you’re with has any of these symptoms, call 911 right away. […] Experts stress the importance of getting treatment for an ischemic stroke right away. On average, 1.9 million brain cells die every minute an ischemic stroke goes untreated, according to the American Stroke Association. […] Getting treated for stroke quickly leads to higher survival rates and lower disability rates. First responders can start treating someone for a stroke even before they get to a hospital. […] A stroke can happen to anyone at any age. The older you are, your chances of having a stroke are increased. However, people younger than 65 also have strokes. About one in seven strokes happen to people ages 15 to 49, according to the CDC. […] It’s important to understand your risk of stroke and ways to help lower your risk.

- #1 Progression in acute ischemic stroke: Is widespread atherosclerotic background a risk factor?https://pmc.ncbi.nlm.nih.gov/articles/PMC6709602/
In this study, we aimed to investigate the causes and conditions related with progression and outcome of progressive acute ischemic stroke. […] Neurological deterioration occurred in 12 patients (15%). […] Progressive acute ischemic stroke patients had carotid stenosis compared to non-progressive patients (50% vs 19%), and ischemic cardiac disease (33% vs 6%) more common in the patients with progression. […] Our study results suggest that widespread atherosclerotic diseases may induce neurological progression. […] Progression of neurological deficits in ischemic cerebrovascular disease is a poor prognostic factor. Worsening of acute stroke early in its course (within 48 to 72 h of its onset) is a common occurrence and has potentially serious short- and long-term consequences for the patient.
- #1 Progression in acute ischemic stroke: Is widespread atherosclerotic background a risk factor?https://pmc.ncbi.nlm.nih.gov/articles/PMC6709602/
The risk of death or dependency at three months of the patients with neurological progression were higher than stable stroke patients in most studies. […] Although the patients with progressive disease had higher NIHSS scores on admission, it did not reach statistical significance. On the other hand, these patients had significantly higher NIHSS scores on discharge. […] In conclusion, our study suggest that widespread atherosclerotic diseases may trigger neurological progression.

If you notice any stroke symptoms, call 911 immediately. Don’t wait to see if symptoms improve or attempt to drive yourself to the hospital. Time is critical during a stroke, and every minute counts in preventing long-term damage. […] Time is brain when stroke occurs. The longer you wait to treat it, the more likely there will be permanent damage to brain cells. Knowing the symptoms of a stroke coming on and acting quickly can be the difference between recovery and disability. Don’t wait to see if symptoms improve immediate medical attention is crucial for the best possible outcomes. […] Different types of strokes present with distinct symptoms that help determine the most appropriate treatment approach. […] An ischemic stroke typically causes symptoms that affect one side of the body. These symptoms develop suddenly and may gradually worsen over minutes to hours as blood flow to the brain becomes restricted.
- #1 Stroke Symptoms and Warning Signs | American Stroke Associationhttps://www.stroke.org/en/about-stroke/stroke-symptoms
On average, 1.9 million brain cells die every minute that a stroke goes untreated. […] Early treatment leads to higher survival rates and lower disability rates. Calling 911 lets first responders start treatment on someone experiencing stroke symptoms before arriving at the hospital. […] Men and women who have strokes often feel similar symptoms of stroke, such as face drooping, arm weakness and speech difficulty. […] However, some signs of stroke in women can be subtle enough to be missed or brushed off. That can lead to delays in getting time-sensitive, lifesaving treatments. […] If youâre having a stroke, itâs critical that you get medical attention right away. Immediate treatment may minimize the long-term effects of a stroke and even prevent death. […] Silent strokes are undetected strokes. They occur when a blood vessel blockage in the brain causes cells to die, but no warning signs or symptoms are obvious.

Sudden numbness or weakness of the face, arm or leg, especially on one side of the body […] Sudden confusion, trouble speaking or difficulty understanding others […] Sudden trouble seeing in one or both eyes […] Sudden trouble walking, dizziness, loss of balance or coordination […] Sudden, severe headache with no known cause […] If you or someone you’re with has any of these symptoms, call 9-1-1 or get yourself or them to a hospital immediately. […] The drug must be given to patients within three- to four-and-a-half hours after the onset of stroke symptoms, and preferably sooner. […] If these signs are present, every second counts. Call 9-1-1 immediately.
- #1 Stroke Facts | Stroke | CDChttps://www.cdc.gov/stroke/data-research/facts-stats/index.html
Stroke is a leading cause of death in the United States and is a major cause of serious disability for adults. It is also preventable and treatable. […] Know the warning signs and symptoms of stroke so that you can act fast if you or someone you know might be having a stroke. The chances of survival are greater when emergency treatment begins quickly. […] In one survey, 93% of respondents recognized sudden numbness on one side as a symptom of stroke. […] Only 38% were aware of all major symptoms and knew to call 9-1-1 when someone was having a stroke. […] Patients who arrive at the emergency room within 3 hours of their first symptoms often have less disability 3 months after a stroke than those who receive delayed care.
- #1 Getting the facts: Can symptoms of stroke come and go?https://www.lcmchealth.org/east-jefferson-general-hospital/blog/2024/may/getting-the-facts-can-symptoms-of-stroke-come-an/
Stroke is a leading cause of death and disability among Americans, affecting about 800,000 people each year. […] When a stroke strikes, immediate medical attention is needed to limit damage to the brain. In most cases, the symptoms come on suddenly, making it obvious that a stroke is occurring, but sometimes, symptoms may quickly appear and then disappear, only to return later. […] If the symptoms of stroke appear and then go away, you should still consider it an emergency. […] Even though symptoms clear up quickly, a TIA should be treated as an emergency health issue. Medical attention is needed to verify whether a TIA occurred or if it was a full-blown ischemic stroke. […] A TIA may not seem like a significant health issue, but its often a warning sign that a stroke will occur in the future. According to the Centers for Disease Control and Prevention, of the people who have a suspected TIA, about 1 in 5 will have a stroke within three months. […] Treating even fleeting stroke symptoms as an emergency can also help you take steps to lower your risk of stroke in the future.

In the United States, stroke kills more women and is more likely to be the first cardiovascular disease to appear. Dr. Mitch Elkind, a neurologist who has researched stroke prevention and treatment extensively, joins House Calls to discuss the unique stroke risk factors women face, the symptoms they should know, and how stroke can be prevented.
- #1 5 things to know about stroke – Mayo Clinic Health Systemhttps://www.mayoclinichealthsystem.org/hometown-health/speaking-of-health/5-things-to-know-about-stroke
Other stroke symptoms to watch for include: Numbness of the face, arm or leg, especially on one side of the body. Sudden confusion, trouble speaking or difficulty understanding speech. Sudden onset severe headache with no known cause. Sudden vision issues, such as trouble seeing in one or both eyes. Trouble walking, loss of balance, dizziness or coordination. […] If you or someone you are with have any stroke-like symptoms, seek immediate medical care. […] Every second counts when someone is experiencing a stroke. Once a stroke starts, the brain loses around 1.9 million neurons each minute. For every hour without treatment, the brain loses as many neurons as it typically does in nearly 3.6 years of regular aging. […] According to the American Stroke Association, stroke is the third most common cause of death in women. Over 90,000 women die from a stroke in the U.S. each year. Every 1 in 5 women will have a stroke, and about 55,000 more women than men have a stroke each year, with Black women having the highest prevalence of stroke.
- #1 Stroke – Symptoms | NHLBI, NIHhttps://www.nhlbi.nih.gov/health/stroke/symptoms
A stroke can cause lasting brain damage, long-term disability, or death. When you have a stroke, your doctor may rate how serious it is. A serious stroke means more brain was damaged. When there is significant damage, your doctor may call it a massive stroke. This can mean there may be severe complications. […] After a stroke, you may develop complications. […] Muscle weakness or inability to move may also occur. A stroke can make your muscles become weak and stiff or cause them to spasm. This can be painful or make it hard to stand or walk around on your own. You may also have problems with balance or controlling your muscles. This puts you at risk of falling. […] Problems with language, thinking, or memory are another possible complication. Stroke may affect your ability to focus on a task or make decisions quickly. It also raises the risk of dementia. […] You may have difficulty speaking. If a stroke affects the muscles you use to speak, you may have trouble communicating as easily as before.
- #1https://www.singhealth.com.sg/patient-care/conditions-treatments/stroke
Recovery after stroke is a natural process. Up to a third of stroke patients recover fully, a third recover partially, and a third do not recover at all. About 10% to 20% may not survive the early period after the stroke. Recovery takes time. Most recovery occurs in the first 3 to 6 months, but it may continue slowly for many years. […] There is a 5% to 15% chance a year of the stroke recurring. To reduce the chance of another stroke, all medications should be taken regularly and smoking must be stopped.
- #1 Childhood Stroke | Types, Causes, Symptoms & Treatmenthttps://www.cincinnatichildrens.org/health/s/stroke
Most people think of a stroke as something that happens to older people. But a stroke can happen to anyone, including teenagers, children, newborns and even unborn babies. In fact, stroke is one of the top 10 causes of death in children. […] A stroke occurs when blood flow to a part of the brain stops because of a clot (ischemic stroke) or because a blood vessel ruptures (hemorrhagic stroke). Blood carries oxygen and other nutrients to the bodys cells and organs. When they cannot reach the brain for more than three minutes, brain cells begin to die. The brain cells continue to die for as long as they are deprived of oxygen. […] Some symptoms of childhood stroke mimic those associated with adult stroke. These include weakness on one side of the body and difficulty communicating. Other symptoms, such as seizure, nausea and vomiting, are more common in children.
- #1 Childhood Stroke | Types, Causes, Symptoms & Treatmenthttps://www.cincinnatichildrens.org/health/s/stroke
Sixty percent of the children who survive a stroke will have permanent neurological problems, ranging from mild to significant. Children often receive occupational and physical therapies for decades to help them learn functional skills of daily living and increase movement if theyre experiencing motor difficulties.
- #2 The Timeline of a Stroke: Onset to Recovery | Fort Duncan Regional Medical Centerhttps://fortduncanmedicalcenter.com/about/blog/timeline-stroke-onset-recovery/
When a stroke happens, every minute counts. Understanding the timeline of a stroke can help you be prepared to act quickly and tackle the recovery journey. […] A stroke can be caused by two major factors: a blockage or a rupture of an artery delivering blood to the brain. An ischemic stroke is a caused by a blocked artery. A hemorrhagic stroke involves bleeding into the brain tissue from a ruptured blood vessel. […] In both kinds of stroke, brain cells stop receiving the flow of oxygen-rich blood that they need. Deprived of oxygen, nerve cells cannot function and begin to die within minutes. When these nerve cells die, the parts of the body they control are impacted and may cease working, too. […] A person having a stroke loses about 2 million brain cells a minute during a stroke, according to the American Heart Association. This is what causes the telltale symptoms, which can include: Loss of balance, Blurred or double vision, Facial drooping, Numbness in the arms or legs, Slurred speech.
- #2 Stroke – Symptoms and causes – Mayo Clinichttps://www.mayoclinic.org/diseases-conditions/stroke/symptoms-causes/syc-20350113
Look for these signs and symptoms if you think you or someone you know is having a stroke: Sudden trouble speaking and understanding what others are saying. Paralysis or numbness of the face, arm or leg on one side of the body. Problems seeing in one or both eyes, trouble walking, and a loss of balance. […] Symptoms of stroke include: Trouble speaking and understanding what others are saying. A person having a stroke may be confused, slur words or may not be able to understand speech.
