Difference Between Brain Hemorrhage And Stroke

Strokes and the Brain

June 1, 2018 Posted by Ranidu

The key difference between brain hemorrhage and stroke is that the strokes are either due to an arterial occlusion or due to the rupturing of an artery.A brain hemorrhage occurs following such an arterial rupture. Thus, brain hemorrhage is actually a cause of stroke.

Strokes are one most of the commonest causes of deaths in the developed countries. They are also on the rise as a major cause of morbidity in the developing countries. They are a syndrome of rapid onset of cerebral deficit which lasts for more than 24 hours or leads to death with no cause apparent other than a vascular one.

What Is A Brain Hemorrhage

As the name implies, a brain hemorrhage is a hemorrhage within the brain tissue. This mostly happens due to a rupturing of a blood vessel due to hypertension.

A damaged artery is unable to supply blood sufficiently. Thus, there are functional impairments in the area that is supplied with blood by this particular. It is these above-mentioned functional impairments that are identified as a hemorrhagic stroke.

Strokes From Brain Bleed Vs Regular Strokes

Strokes from brain bleed and regular strokes have many common symptoms. However, there are a few symptoms that are more specific to a stroke with brain bleed. The most important distinguishing symptom is the presence or absence of a headache. A regular ischemic stroke is almost always painless. I have explained this in the article stroke vs heart attack. It is very unusual for someone with a regular stroke to have a bad headache. When you have a bad headache with stroke-like symptoms, you are more likely to have a stroke from brain bleed.

Here is a table comparing the symptoms of hemorrhagic strokes with ischemic strokes:

Are There Different Types Of Brain Avms

  • True arteriovenous malformation . This is the most common brain vascular malformation. It consists of a tangle of abnormal vessels connecting arteries and veins with no normal intervening brain tissue.
  • Occult or cryptic AVM or cavernous malformations. This is a vascular malformation in the brain that doesnt actively divert large amounts of blood. It may bleed and often produce seizures.
  • Venous malformation. This is an abnormality only of the veins.
  • Hemangioma. These are abnormal blood vessel structures usually found at the surface of the brain and on the skin or facial structures.
  • Dural fistula. The covering of the brain is called the dura mater. An abnormal connection between blood vessels that involve only this covering is called a dural fistula. Dural fistulas can occur in any part of the brain covering. Three kinds of dural fistulas are:
  • Dural carotid-cavernous sinus fistula. These occur behind the eye. Patients have eye swelling, decreased vision, redness and congestion of the eye. They often can hear a swishing noise.
  • Transverse-Sigmoid sinus dural fistula. These occur behind the ear. Patients usually complain of hearing a continuous noise that occurs with each heartbeat, local pain behind the ear, headaches and neck pain.
  • Sagittal sinus and scalp dural fistula. These occur toward the top of the head. Patients complain of noise , headaches, and pain near the top of the head they may have prominent blood vessels on the scalp and above the ear.

Aneurysm Versus Stroke Symptoms

doctordconline: Different types of Brain stroke, ischemic ...

If an aneurysm has not burst, there are not usually any symptoms.

A sudden headache is the main difference between a burst aneurysm and a stroke that results from a blood clot.

Within seconds of a brain aneurysm bursting, there is usually a severe headache.

Other signs and symptoms may differ between a burst aneurysm and common stroke. Sudden extreme headache is the one that is noticeably different, however.

A stroke is a medical emergency. Blood supply to parts of the brain suddenly stops, starving these parts of oxygen and nutrients. This can cause the death of brain tissue.

A stroke can be ischemic or hemorrhagic.

Ischemic stroke: An artery is blocked, and blood supply no longer reaches all the parts of the brain.

Hemorrhagic stroke: A blood vessel bursts or leaks, and blood enters parts of the brain where it would not normally be.

The two types of hemorrhagic stroke are:

Intracerebral: Bleeding occurs within the brain.

Subarachnoid: Bleeding happens over the surface of the brain, and blood enters the fluid-filled space between the brain and the underside of the skull bone. It is uncommon. A physical effort or straining can trigger it.

Most strokes are ischemic.

An aneurysm is a bulge in an artery. It bulges because of a weakness in an artery wall. This makes the artery open to further weakening, and it could burst.

Aneurysms varyin shape, size, and location.

What Causes Bleeding In The Brain

There are several risk factors and causes of brain hemorrhages. The most common include:

  • Head trauma. Injury is the most common cause of bleeding in the brain for those younger than age 50.
  • High blood pressure. This chronic condition can, over a long period of time, weaken blood vessel walls. Untreated high blood pressure is a major preventable cause of brain hemorrhages.
  • Aneurysm. This is a weakening in a blood vessel wall that swells. It can burst and bleed into the brain, leading to a stroke.
  • Blood vessel abnormalities. Weaknesses in the blood vessels in and around the brain may be present at birth and diagnosed only if symptoms develop.
  • Amyloid angiopathy. This is an abnormality of the blood vessel walls that sometimes occurs with aging and high blood pressure. It may cause many small, unnoticed bleeds before causing a large one.
  • Blood or bleeding disorders. Hemophilia and sickle cell anemia can both contribute to decreased levels of blood platelets and clotting. Blood thinners are also a risk factor.
  • Liver disease. This condition is associated with increased bleeding in general.

What Is A Brain Avm

Normally, arteries carry blood containing oxygen from the heart to the brain, and veins carry blood with less oxygen away from the brain and back to the heart. When an arteriovenous malformation occurs, a tangle of blood vessels in the brain bypasses normal brain tissue and directly diverts blood from the arteries to the veins.

What Causes A Haemorrhagic Stroke

High blood pressure

The main cause of haemorrhagic stroke is damage to the very small arteries inside the brain, which is often related to high blood pressure .

This process, called small vessel disease, makes the small arteries in the brain more prone to bleeding. Cerebral amyloid angiopathy

This is a common type of small vessel disease where a protein called amyloid builds up inside the small blood vessels near the surface of the brain. The resulting damage can cause a vessel to tear, causing bleeding.

This condition is more common among older people, and older people with dementia. Although there are no proven treatments for CAA, controlling blood pressure can help reduce the risk of bleeding in the brain.

Magnetic resonance imaging scans have shown that CAA is present in patients with bleeds in specific areas of the brain near to the surface , known as lobar intracerebral haemorrhage. Smaller bleeds, which can be detected on MRI scans, are called microbleeds. Microbleeds are a common feature of CAA and often appear without symptoms.

Burst aneurysm

An aneurysm is a weak spot on an artery that has ballooned out. Artery walls are usually thick and strong, but the walls of an aneurysm are thin and weak because they have been stretched. Aneurysms most commonly occur in the main artery leading away from the heart , and the brain.

A brain bleed occurs when there is a ruptured blood vessel that creates bleeding in and around the brain. According to the Brain Aneurysm Foundation, approximately 30,000 Americans experience a brain aneurysm rupture each year. How do you know if you could be one of them?

David Wiles, MD, neurosurgeon at Parkridge Medical Center, sat down with us to discuss brain bleeds and how you can recognize the symptoms as soon as possible in order to obtain medical care and treatment.

What Treatments Are Available

Treatment may include lifesaving measures, symptom relief, and complication prevention. Once the cause and location of the bleeding is identified, medical or surgical treatment is performed to stop the bleeding, remove the clot, and relieve the pressure on the brain. If left alone the brain will eventually absorb the clot within a couple of weeks however the damage to the brain caused by ICP and blood toxins may be irreversible.

Generally, patients with small hemorrhages and minimal deficits are treated medically. Patients with cerebellar hemorrhages who are deteriorating or who have brainstem compression and hydrocephalus are treated surgically to remove the hematoma as soon as possible. Patients with large lobar hemorrhages who are deteriorating usually undergo surgical removal of the hematoma.

Medical treatment The patient will stay in the stroke unit or intensive care unit for close monitoring and care.

Surgical treatment The goal of surgery is to remove as much of the blood clot as possible and stop the source of bleeding if it is from an identifiable cause such as an AVM or tumor. Depending on the location of the clot either a craniotomy or a stereotactic aspiration may be performed.

How Is A Brain Hemorrhage Treated

Once you see a doctor, they can determine which part of the brain is affected based on your symptoms.

Doctors may run a variety of imaging tests, such as a CT scan, which can reveal internal bleeding or blood accumulation, or an MRI. A neurological exam or eye exam, which can show swelling of the optic nerve, may also be performed. A lumbar puncture is usually not performed, as it may be dangerous and make things worse.

Treatment for bleeding in the brain depends on the location, cause, and extent of the hemorrhage. Surgery may be needed to alleviate swelling and prevent bleeding. Certain medications may also be prescribed. These include painkillers, corticosteroids, or osmotics to reduce swelling, and anticonvulsants to control seizures.

What Is The Outlook For Strokes And Aneurysms

A ruptured aneurysm is a life-threatening condition, with high mortality rates, particularly in the first days of the event. Many people who survive a ruptured aneurysm have effects that linger for the rest of their lives. Brain damage due to bleeding is irreversible.

Aneurysms that have not ruptured may still need treatment based on their size, location, and shape as these factors determine the likelihood of rupturing in the future.

The outlook for people who have a stroke is much more varied. An ischemic stroke can be either be devastating or relatively mild. Some ischemic stroke survivors have few if any long-term symptoms. A hemorrhagic stroke, on the other hand, is more likely to be deadly or leave a person with cognitive or physical disabilities.

The location of the stroke and time that goes by before blood flow is restored makes a difference in your recovery. Rapid treatment may make the difference between being able to walk and talk normally or requiring a walker and years of speech therapy.

Symptoms Of A Hemorrhagic Stroke

Left Cerebral Hemorrhage

When an intracerebral hemorrhage occurs, it not only deprives the brain of oxygen, it can cause severe swelling and compression of the brain itself. Symptoms can vary but typically include:

  • Sudden and severe headache
  • Problems with speech or swallowing
  • Seizures

Intracerebral hemorrhage is a devastating event with a 30-day mortality rate of around 40%, according to the journal Interventional Neurology.

Stay Healthy And Get Yourself Checked

The best way to avoid aneurysms and strokes is to adopt a healthy lifestyle and to visit your doctor regularly. Be aware of major risk factors like smoking, which plays into both conditions as it promotes both atherosclerosis and blood clots.

Remember to visit your doctor at least once a year, and contact them whenever you have symptoms that worry you.

What Happens To The Brain When There Is Bleeding Inside The Head

Since the brain cannot store oxygen, it relies upon a series of blood vessels to supply oxygen and nutrients. When a brain hemorrhage occurs, oxygen may no longer be able to reach the brain tissue supplied by these leaky or burst vessels. Pooling of blood from an intracranial hemorrhage or cerebral hemorrhage also puts pressure on the brain and deprives it of oxygen.

When a hemorrhage interrupts blood flow around or inside the brain, depriving it of oxygen for more than three or four minutes, the brain cells die. The affected nerve cells and the related functions they control are damaged as well.

Are The Causes Of A Stroke And Brain Aneurysm The Same

No, the causes of these two conditions are very different.

Stroke causes

Strokes are caused when oxygen is cut off to brain cells. Ischemic stroke happens when a blood clot blocks an area in an arterial blood vessel in the brain. This type of stroke accounts for about 80% of strokes.

  • Ischemic strokes are caused by blood clots that form on the inside of the arteries or by a blood clot or cholesterol plaque fragment from elsewhere in the body .
  • A hemorrhagic stroke is due to blood leaking out of a brain artery into brain tissue. Because of this leakage, the brain receives less oxygen. And, because the blood is under pressure, the bleeding into adjacent brain tissue can compress other vessels and deprive areas next the injured blood vessel or artery of oxygen. This type of stroke accounts for about 20% of strokes.

Brain aneurysm causes

A brain aneurysm may be caused by congenital blood vessel problems happen as a result of blood vessel disease over time, or result from injury and/or damage to the blood vessel. Almost all brain aneurysms have no symptoms until they begin to leak blood. When the aneurysm leaks blood, it is considered to be a cause of a hemorrhagic stroke and this is a medical emergency.

What Is The Difference Between A Stroke And An Aneurysm

What Is A Brain Hemorrhage?

Strokes and aneurysms are similar in some ways, but also different. While both have potentially disabling consequences because they directly affect the brain, strokes and aneurysms have different symptoms and are caused by separate events.

Both strokes and aneurysms are serious conditions. Knowing more about them prepares you to understand and identify the symptoms faster so you can get medical help quickly.

What Are The Symptoms Of Brain Bleeds

Symptoms of a brain hemorrhage depend on the area of the brain involved. In general, symptoms of brain bleeds can include:

  • Sudden tingling, weakness, numbness, or paralysis of the face, arm or leg, particularly on one side of the body.
  • Headache.
  • Nausea and vomiting.
  • Loss of vision or difficulty seeing.
  • Loss of balance or coordination.
  • Stiff neck and sensitivity to light.
  • Abnormal or slurred speech.
  • Difficulty reading, writing or understanding speech.
  • Change in level of consciousness or alertness, lack of energy, sleepiness or coma.
  • Trouble breathing and abnormal heart rate .

What Is An Ischemic Stroke

An ischemic stroke occurs when a blood vessel that supplies the brain becomes blocked or “clogged” and impairs blood flow to part of the brain. The brain cells and tissues begin to die within minutes from lack of oxygen and nutrients. Ischemic strokes are further divided into 2 groups:

  • Thrombotic strokes. These are caused by a blood clot that develops in the blood vessels inside the brain.

  • Embolic strokes. These are caused by a blood clot or plaque debris that develops elsewhere in the body and then travels to one of the blood vessels in the brain through the bloodstream.

What Different Types Of Treatment Are Available

  • Medical therapy. If there are no symptoms or almost none, or if an AVM is in an area of the brain that cant be easily treated, conservative management may be called for. These patients are advised to avoid excessive exercise and stay away from *blood thinners like warfarin.
  • Surgery. If an AVM has bled and/or is in an area that can be easily accessed, then surgery may be recommended.
  • Stereotactic radiosurgery. An AVM thats not too large but is in an area thats difficult to reach by regular surgery may be treated with stereotactic radiosurgery. In this procedure, a cerebral angiogram is done to localize the AVM. Focused-beam high energy sources are then concentrated on the AVM to cause a scar and allow the AVM to clot off.
  • Interventional neuroradiology/endovascular neurosurgery. It may be possible to treat part or all of the AVM by placing a catheter inside the blood vessels and blocking off the abnormal vessels with various materials, such as glue or coils.

How Is Subarachnoid Hemorrhage Diagnosed

Hemorrhagic Stroke (With images)

If you have symptoms of a subarachnoid hemorrhage, a doctor might use several tests to diagnose it:

  • MRI scan. This test uses large magnets, radiofrequency energy, and a computer to make detailed images of the brain.

  • CT scan. This test uses X-rays and computer technology to make horizontal, or axial images of the brain. CT scans are more detailed than general X-rays.

  • Angiogram. During this test, dye is injected in the blood vessel and then X-rays are taken to evaluate blood flow through them.

  • Spinal tap. In this test, a special needle is placed into the lower back, into the spinal canal. The pressure in the spinal canal and brain can be measured. A small amount of cerebrospinal fluid can be removed and analyzed for the presence of blood

A diagnosis of a cerebral aneurysm isn’t usually made until a subarachnoid hemorrhage has already occurred.
