What are the two types of ischemic strokes?
Types of Stroke
- Ischemic Stroke. An ischemic stroke happens when a blood vessel supplying blood to your brain gets blocked by a blood clot.

What is the most severe type of stroke?
Hemorrhagic strokes are extremely dangerous because the blood in the brain can sometimes lead to further complications such as hydrocephalus, increased intracranial pressure, and blood vessel spasms. If not treated aggressively, these conditions can lead to severe brain damage and even death.
Are hemorrhagic strokes more severe?
Conclusion— Strokes are generally more severe in patients with HS. Within the first 3 months after stroke, HS is associated with a considerable increase of mortality, which is specifically associated with the hemorrhagic nature of the lesion.
Is hemorrhagic stroke the same as ischemic?
Stroke can be either ischemic or hemorrhagic. Ischemic stroke is due to the loss of blood supply to an area of the brain. It is a common type of stroke. Hemorrhagic stroke is due to bleeding into the brain by the rupture of a blood vessel.
What is the difference between ischemia and hemorrhage?
An ischemic stroke occurs when a blood vessel supplying the brain becomes blocked, as by a clot. A hemorrhagic stroke occurs when a blood vessel bursts, leaking blood into the brain.
Which strokes have the worse outcomes?
Overall, the general prognosis of ischemic stroke is considered better than that of hemorrhagic stroke, in which death occurs especially in the acute and subacute phases [2,3].
Why is a hemorrhagic stroke worse?
Accumulated blood also puts pressure on surrounding brain areas, damaging or destroying them. Hemorrhagic strokes are particularly dangerous because they cause severe symptoms that get worse quickly. Without fast medical attention, these strokes often cause permanent brain damage or even death.
Can you fully recover from a hemorrhagic stroke?
Is rehabilitation always successful? According to the National Stroke Association, 10 percent of people who have a stroke recover almost completely, with 25 percent recovering with minor impairments. Another 40 percent experience moderate to severe impairments that require special care.
What is the life expectancy after a hemorrhagic stroke?
First-Stroke Patients' 5-Year Survival Rates Study Of the surviving patients, 60 percent who suffered an ischemic stroke and 38 percent with intracerebral hemorrhage survived one year, compared to 31 percent and 24 percent, respectively, after five years.
Can a person survive a hemorrhagic stroke?
The survival rate after hemorrhagic stroke was 26.7% within a period of five years. Long-term survival rate prognosis is significantly better among the younger patients, without hypertension, alcohol intake and diabetes mellitus.
Which type of stroke has better recovery?
Those who suffer ischemic strokes have a much better chance for survival than those who experience hemorrhagic strokes, as hemorrhagic stroke not only damages brain cells but also may lead to increased pressure on the brain or spasms in the blood vessels [9].
Is death by brain hemorrhage painful?
A brain bleed can cause symptoms that rapidly worsen over hours or days. Symptoms of a brain bleed may include Headache, Neck or spinal cord pain, Vision changes, Weakness on one side of the face or body, Nausea and vomiting, Confusion, Behavioral changes, Loss of consciousness.
What is the average life expectancy after a stroke?
The median survival time after a first stroke are: at 60-69 years of age–6.8 years for men and 7.4 years for women; at 70-79 years of age–5.4 years for men and 6.4 years for women; and at 80 years and older–1.8 years for men and 3.1 years for women.
What are the chances of surviving a hemorrhagic stroke?
Survival Probabilities Following Hemorrhagic or Ischemic Stroke. In the hemorrhagic stroke group, survival probabilities were as follows: 6 months (36% [95% CI, 28–43]), 1 year (34% [95% CI, 27–41]), 2 years (31% [95% CI, 24–38]), and 3 years (27% [95% CI, 20–33]).
What is the prognosis for hemorrhagic stroke?
Intracerebral hemorrhage accounts for 10–15% of all strokes and carries very high morbidity and mortality rates that have not changed over the last 30 years. At one year, mortality ranges from 51% to 65% depending on the location of the hemorrhage.
Can you fully recover from a hemorrhagic stroke?
Is rehabilitation always successful? According to the National Stroke Association, 10 percent of people who have a stroke recover almost completely, with 25 percent recovering with minor impairments. Another 40 percent experience moderate to severe impairments that require special care.
Is death by brain hemorrhage painful?
A brain bleed can cause symptoms that rapidly worsen over hours or days. Symptoms of a brain bleed may include Headache, Neck or spinal cord pain, Vision changes, Weakness on one side of the face or body, Nausea and vomiting, Confusion, Behavioral changes, Loss of consciousness.
What Are Ischemic and Hemorrhagic Strokes?
The most commonly occurring type of stroke, ischemic strokes happen when a blood clot blocks blood flow to the brain. Approximately 795,000 people in the United States have experienced a new or recurrent stroke, making strokes the leading cause of disability and fifth leading cause of death in America. It is estimated that 82–92 percent of all strokes occurring in the United States are ischemic in origin.
What percentage of strokes are ischemic?
It is estimated that 82–92 percent of all strokes occurring in the United States are ischemic in origin. Hemorrhagic strokes are less common, with only 15 percent of strokes being hemorrhagic. On the other hand, there is a higher risk of death from hemorrhagic stroke, with 40 percent of cases resulting in death.
What is a stroke called when blood is cut off from the brain?
There are several different types of stroke including ischemic stroke , where blood supply is cut off from the brain; hemorrhagic stroke, where bleeding occurs in the brain; and a transient ischemic stroke , also known as a mini-stroke, where symptoms occur for a shorter period and blood loss to the brain is temporary.
What is the key to surviving a stroke?
The key to surviving a stroke is early detection. This means paying attention to the main symptoms of a stroke. The acronym to follow is FAST, which refers to changes in the Face, Arms, and Speech. Here we will do a comparative analysis of ischemic stroke and hemorrhagic stroke regarding their causes, symptoms, diagnosis, treatment, and prognosis. ...
How do you know if you have a stroke?
Some of the most common symptoms of ischemic and hemorrhagic stroke are: Weakness and numbness in the face, arm, or leg, occurring particularly on one side. Confusion, difficulty speaking and understanding sentences. Difficulty with balance, walking, and coordination. Problems with vision in one or both eyes and sudden dizziness.
How long does it take to recover from a hemorrhagic stroke?
As mentioned, hemorrhagic stroke has a high death rate, so immediate medical treatment is the key to a positive prognosis. Recovery may take months or even years and doctors will provide patients with a plan to follow when they go back home to ensure they reduce the risk of a future stroke from occurring.
How to diagnose hemorrhagic stroke?
The doctor will look out for the standard stroke-related symptoms. To specifically diagnose a hemorrhagic stroke, the doctor will need to use imaging scans. Lastly, the doctor may also perform an electroencephalogram (EEG) or lumbar puncture (spinal tap) to confirm the diagnosis.
How To Differentiate Ischemic and Hemorrhagic Stroke
The primary difference between ischemic and hemorrhagic stroke lies in how the blood flow in the artery is interrupted, leading to brain tissue damage. Likewise, ischemic stroke is more common, comprising about 87% of stroke cases, while hemorrhagic makes up to only 10% to 20% .
Risk Factors for Stroke
While it’s true that stroke can happen to anyone, anytime, some people have higher affinity for the disease due to the following risk factors:
Ischemic Stroke vs. Hemorrhagic Stroke Diagnosis
Brain scans are often performed to diagnose a stroke. Your doctor will request for an imaging test to detect the blood clot in the cerebral artery. Aside from these tests, you will also most likely take blood tests such as a lipid panel blood test and a glucose blood test.
Treatments for Stroke
The kind of stroke treatment plan depends on the type, and severity of the condition, especially if it is an emergency. Below are some references on how doctors treat ischemic and hemorrhagic stroke.
Bottom Line
In the battle between ischemic vs hemorrhagic stroke, nobody’s a winner except those who understand the simple ways to prevent them. With that, knowing the difference between the two allows you to look closer into your risks.
What are the differences between ischemic and hemorrhagic strokes?
Background. Ischemic and hemorrhagic strokes have different pathophysiologies and possibly different long-term cerebral and functional implications. Hemorrhagic strokes expose the brain to irritating effects of blood and ischemic strokes reflect localized or diffuse cerebral vascular pathology. Methods. Participants were individuals who suffered either an ischemic (n= 172) or hemorrhagic stroke (n= 112) within the past six months and were involved in a postacute neurorehabilitation program. Participants completed three months of postacute neurorehabilitation and the Mayo Portland Adaptability Inventory-4 (MPAI-4) at admission and discharge. Admission MPAI-4 scores and level of functioning were comparable. Results. Group ANOVA comparisons show no significant group differences at admission or discharge or difference in change scores. Both groups showed considerably reduced levels of productivity/employment after discharge as compared to preinjury levels. Conclusions. Though the pathophysiology of these types of strokes is different, both ultimately result in ischemic injuries, possibly accounting for lack of findings of differences between groups. In the present study, participants in both groups experienced similar functional levels across all three MPAI-4 domains both at admission and discharge. Limitations of this study include a highly educated sample and few outcome measures.
What is the employment rate of ischemic/hemorrhagic?
Both groups (ischemic/hemorrhagic) had a very high level of employment before injury (71% and 85.7%, resp.), a very low level of employment at the onset of postacute rehabilitation (3.5% and 8.9%, resp.), but considerably improved employment at time of discharge (22% and 23.2%, resp.; see Tables Tables33and and44).
What is the risk of ICH?
ICH is associated with a higher risk of fatality compared with cerebral infarction and approximately half of all patients with primary ICH die within the first month after the acute event [2–4, 7]. Additionally, patients who are aged 85 and above, compared to younger patients, tend to experience higher clinical severity (moderate or severe neurological deficit at time of hospital discharge of 89% versus 58%) and greater in-hospital mortality rate (50% versus 27% [8]). Those who suffer ischemic strokes have a much better chance for survival than those who experience hemorrhagic strokes, as hemorrhagic stroke not only damages brain cells but also may lead to increased pressure on the brain or spasms in the blood vessels [9]. Of note, there are three main processes implicated in neurorecovery: angiogenesis, neurogenesis, and synaptic plasticity. These processes are naturally produced in adult brains subsequent to intensive rehabilitation, which could promote an endogen neurorepair phenomenon [10].
Do ICH and CI CVAs show functional recovery?
As the majority of the research conducted on inpatients who experienced CVAs showed that those with ICH CVAs exhibited more functional recovery, in the present study, it was hypothesized that individuals with hemorrhagic strokes would show more functional recovery by completion of postacute brain injury rehabilitation than individuals with ischemic strokes.
Does ICH predict long term disability?
On the other hand, one study demonstrated that, among conscious stroke patients, ICH predicted poor neurologic outcome, nearly doubling the odds of long-term disability as compared to ischemic stroke [23]. However, some studies show no functional differences between the two groups. For example, Franke et al. [24] observed no difference in level of functional independence after one year of follow-up between ICH and CI patients and concluded that the extent of the brain lesion was the determining factor in outcome in those who survive the first two days after CVA.
Is stroke severity a factor?
Stroke severity appears to be an influential factor in predicting outcome. In one study, stroke type had no influence on mortality, neurological or functional outcome, or time course of recovery, with initial stroke severity, the most important factor [25]. The authors concluded that poorer prognosis in those with ICH is due to the increased frequency of those ICH who experienced increased stroke severity [25]. Similarly, in another study, those with more severe ICH exhibited significantly greater recovery than those with CI of a similar CVA severity [22].
Is hemorrhagic CVA better than ischemic CVA?
Several studies found differences in functional outcome between those with ischemic versus hemorrhagic CVAs; some studies found better functional prognosis in survivors with hemorrhagic CVA after inpatient rehabilitation [20, 21], whereas others found that those with ICH strokes exhibited greater functional impairment and greater improvement than ischemic strokes but progressed more slowly [19, 22]. Additionally, patients with hemorrhagic CVAs have a higher early mortality rate [2]. Therefore, those in the present study with hemorrhagic CVAs may not be truly representative of the general population. The results of the present study may differ from previous studies due to younger age, greater level of education, increased racial diversity, and high level of functioning upon admission to the postacute rehabilitation program.
What is ischemic stroke vs. hemorrhagic stroke?
There are two primary types of strokes: a hemorrhagic stroke and an ischemic stroke. You should contact emergency services right away if you suspect that you or someone else is having a stroke. Early treatment can save a life and raise the chances of recovering successfully from the stroke event.
What is the difference between a stroke and a hemorrhagic stroke?
A stroke is a bleeding or clotting event that interferes with blood flow to the brain. An ischemic stroke is when blood vessels to the brain become clogged. A hemorrhagic stroke is when bleeding interferes with the brain's ability to function.
What causes a stroke to be ischemic?
hemorrhagic stroke? Hemorrhagic strokes occur when the brain loses access to its vital blood supply because of bleeding from a blood vessel. On the other hand, ischemic strokes happen when there is a blockage in one of the blood vessels feed ing the brain.
How long does it take for a mini stroke to go away?
Mini-stroke side effects usually resolve within minutes to a couple of days. A transient ischemic attack (mini-stroke) is a precursor for stroke because 40% of individuals who have a mini-stroke will have a stroke within a year. Treatment of stroke depends upon the type and parts of the body affected.
What happens when the blood vessels responsible for carrying blood to the brain become clogged?
What is an ischemic stroke? Ischemic strokes happen when the blood vessels responsible for carrying blood to the brain become clogged, which leads to the death of brain tissue. There are two different types of ischemic strokes:
How to get rid of a clot after a stroke?
If you had an ischemic stroke, doctors would focus on removing the clot through medication or surgery. If you undergo surgery, your doctor may recommend you attend rehabilitation to regain functionality in the parts of your body affected by the stroke.
Why is aspirin used for stroke?
Platelets are needed in order for blood clots to form. Because aspirin inhibits blood clotting, it is used to reduce the risk of recurrent stroke and near-stroke (transient ischemic attack). Aspirin therapy is used to prevent heart attacks and treat heart attacks.
How much more likely is a hemorrhagic stroke to cause death than an ischemic stroke?
According this, hemorrhagic strokes are, overall, 40-70% more likely to cause death than are ischemic strokes. The risk asymmetry is most pronounced in the first week, during which hemorrhagic strokes are about 4 times more likely to fatal.
What is the first exam to be performed for a stroke?
When a patient comes do the Emergency Room with an acute neurological deficit and the probable diagnosis is a stroke, the first exam to be performed is a CT scan to exclude intracranial haemorrhage, which would preclude thrombolysis; to look for any "early" signs of infarction; and to exclude other intracranial pathologies that may mimic a stroke, such as tumour.
Does TPA help with stroke?
All strokes cause brain damage. tPA can reduce damage from ischemic strokes. When I had a stroke, I was taken directly from the ambulance to the CT, where they told me I had a bleed in the brain. No tPA for me.
Is a hemmorhagic stroke more likely to be fatal than an ischemic stroke?
Hemorrhagic strokes are more likely to be fatal than ischemic, though less common (87% of strokes are ischemic). Both can be fatal, both can cause severe brain damage, paralysis and numerous other problem, but a brain bleed is more difficult to stop than a clot…they have drugs that can take care of the clot if administered within a few hours of the onset of symptoms. A bleed is more difficult to fix.
Can a stroke be a full recovery?
The outcomes of stroke or cerebral hemorrhage depends on the size of the stroke/bleed, presenting neurological status, timing to intervention, and medical comorbidities. Patients can make a full recovery, they can die, and can have every outcome in between. Some studies have looked at the morbidity and mortality rate of ischemic versus hemorrhagic strokes and found that hemorrhagic strokes were generally associated with an overall higher mortality risk. But in practice, consider the following:
Is a haemorrhagic stroke amenable to thrombolysis?
I reckon haemorrhagic because an ischaemic stroke is potentially amenable to thrombolysis (that is breaking down of the clot causing the problem thereby restoring normL blood flow)
Is it dangerous to have a brain bleed?
You might notice I kept using the term " if survived." Massive brain bleeds are extremely dangerous and not too many people survived one.
What is a hemorrhagic stroke?
A hemorrhagic (pronounced “hem-or-aj-ick”) stroke is a life-threatening medical condition that happens when a blood vessel in your brain ruptures and bleeds. This can disrupt the normal circulation of blood in your brain, starving some areas of oxygen. Accumulated blood also puts pressure on surrounding brain areas, damaging or destroying them.
Who does it affect?
Hemorrhagic strokes are most common in people with diseases that affect their circulatory system, which includes the heart and blood vessels. Problems like these are more common as people get older, so these kinds of strokes are more common later in life.
How common is a hemorrhagic stroke?
Strokes are very common. Worldwide, strokes rank second among the top causes of death. In the United States, they rank fifth. Hemorrhagic strokes make up about 10% to 15% of all strokes.
How does this condition affect my body?
A hemorrhagic stroke causes severe bleeding in or around your brain. Because this is happening inside of your skull, there’s only so much space for the bleeding to go. That puts too much pressure on the surrounding brain tissue, damaging it.
What are the different types of hemorrhagic stroke?
Bleeding inside the brain (intracerebral). This causes bleeding inside your brain, putting pressure on the surrounding brain tissue from the inside.
What are the symptoms of a hemorrhagic stroke?
The symptoms of a hemorrhagic stroke can include one or more of the following:
What causes hemorrhagic strokes?
The most common cause of a hemorrhagic stroke is high blood pressure (hypertension). This is especially true when a person’s blood pressure is very high, stays high for a long time, or both. Other conditions or causes of hemorrhagic strokes include:
How long do you stay in hospital after a stroke?
The average hospital stay in acute care for stroke patients is between four days (ischemic) and seven days (hemorrhagic). Survivors are generally transferred from acute care to an inpatient rehabilitation facility (IRF), a skilled nursing facility (SNF) or a long-term acute care (LTAC) hospital.
What is the life expectancy after a stroke?
Standardized mortality ratios were calculated for various causes of death and periods after the stroke. Results— The estimated cumulative risks for death at 28 days, 1 year, and 5 years after onset were 28%, 41%, and 60%, respectively.
Why do people get strokes?
Causes of strokes include ischemia (loss of blood supply) or hemorrhage (bleeding) in the brain. People at risk for stroke include those who have high blood pressure, high cholesterol, diabetes, and those who smoke.
What is a silent stroke?
Silent stroke: Small strokes that do not cause any symptoms. Silent strokes still damage brain tissue. The most common symptom of a stroke is weakness or paralysis on one side of the body or the other. A stroke involving the base of the brain can affect balance, vision, and swallowing functions.
What is the most dangerous stroke?
Doctors discovered she was having a hemorrhagic stroke. Most strokes are caused by a clot that cuts off blood flow to the brain. But about 13 percent are caused by a weakened blood vessel that ruptures and bleeds into the brain. These so-called hemorrhagic strokes are the deadliest and least treatable type.
How can I prevent strokes?
Stroke prevention can start today. Protect yourself and avoid stroke, regardless of your age or family history. Lower blood pressure. Lose weight. Exercise more. If you drink — do it in moderation. Treat atrial fibrillation. Treat diabetes. Quit smoking.
Can you stop a stroke from happening?
A clot-busting medication called tPA, or tissue plasminogen activator, can be given to someone if they’re having a stroke, potentially reversing or stopping symptoms from developing. But it has to be given within 4.5 hours of the start of symptoms, Jean says.
What is HT in stroke?
Hemorrhagic transformation (HT) is a common complication in patients with acute ischemic stroke. It occurs when peripheral blood extravasates across a disrupted blood brain barrier (BBB) into the brain following ischemic stroke. Preventing HT is important as it worsens stroke outcome and increases mortality. Factors associated with increased risk of HT include stroke severity, reperfusion therapy (thrombolysis and thrombectomy), hypertension, hyperglycemia, and age. Inflammation and the immune system are important contributors to BBB disruption and HT and are associated with many of the risk factors for HT. In this review, we present the relationship of inflammation and immune activation to HT in the context of reperfusion therapy, hypertension, hyperglycemia, and age. Differences in inflammatory pathways relating to HT are discussed. The role of inflammation to stratify the risk of HT and therapies targeting the immune system to reduce the risk of HT are presented.
What happens when the blood-brain barrier is disrupted?
It occurs when the blood-brain barrier (BBB) is sufficiently disrupted to permit extravasation of peripheral blood into the brain. When HT occurs, it increases stroke morbidity and mortality and thus is important to prevent ( 2 ).
Is there a relationship between brain ischemia and HT?
There is a strong relationship between duration and severity of brain ischemia and the risk of HT in both patients with stroke and experimental stroke models. Increased time from stroke onset is associated with larger core volumes, a higher degree of vascular disruption, and therefore a higher risk of HT.
