T2 Mri Brain Hemorrhage

[Kristin Banyas]

Abrain hemorrhage is a type of stroke. It happens when a weakened blood vessel in your brain starts to leak or suddenly bursts. As a result, your brain cells can't get enough oxygen and nutrients. That can severely damage them.

Your brain isn't a muscle. It's a complex organ that contains a finely tuned network of both nerves and blood vessels. But sometimes, one or more of these blood vessels can become weak from damage or even burst.

Once blood begins leaking out of a vessel, it can irritate the surrounding brain tissue and cause swelling. This is known as cerebral edema. The pooled blood collects into a mass called a hematoma. Your skull does a good job of protecting your brain by keeping it tightly contained. There's not a lot of space between your brain and skull. But that means conditions like these can quickly increase pressure on your brain, which reduces vital blood flow and can damage brain cells.

Epidural bleed. This is when blood collects between your skull and the thick outer layer, called the dura mater. Without treatment, it can make your blood pressure rise, make it hard to breathe, cause brain damage, or lead to death.

Subdural bleed. If blood leaks between your dura mater and the thin layer beneath it, called the arachnoid mater, you have this type of brain hemorrhage. There are three main kinds of subdural bleeds:

Subarachnoid bleed. This is when blood collects below the arachnoid mater and above the delicate inner layer beneath it, the pia mater. Without treatment, it can lead to permanent brain damage and death.

A bleed like this usually happens because of a head trauma, like hitting your head in a car accident. But sometimes it can be due to a brain aneurysm, a bulge in one of your brain vessels. And another issue with your blood vessels or a separate health condition can also cause it. The main warning sign for this type of bleed is a sudden, severe headache.

Intraventricular hemorrhage. In this case, bleeding happens within the ventricles of your brain -- the little chambers that typically contain cerebral spinal fluid. That may damage your nerve cells and lead to lasting brain injury. Intraventricular hemorrhage is more common in premature babies or babies who are born with very low birthweights (under 3 1/2 pounds).

A brain hemorrhage refers to bleeding inside your brain or in between your brain and your skull. The blood that collects as a result is called an intracranialhematoma. It can require surgery right away to remove the extra blood and relieve the pressure that it's putting on your brain.

Blood vessel abnormalities(arteriovenous malformations). You might be born with weakened blood vessels in and around your brain. But you might not know about them unless you start having symptoms.

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.

The symptoms of a brain hemorrhage can vary. They depend on where the bleeding is, how much it's bleeding, and the amount and location of your brain tissue that's affected. Symptoms often start all of a sudden. Then they may get worse over time.

Keep in mind that a lot of these symptoms can be caused by many other conditions. But because a brain hemorrhage can be a life-threatening condition, it's important to play it safe. Call 911 or go to an emergency room as soon as you can.

After a physical exam, they'll likely run some imaging tests, such as a CT scan, which can reveal internal bleeding, or an MRI. Other tests can help identify the cause of your brain hemorrhage. For instance, your doctor might order bloodwork, a urine test, X-rays, or an electroencephalogram (EEG), a painless test that checks your brain activity.

Your treatment will depend on the location, cause, and extent of your brain hemorrhage. In some cases, you might be prescribed medication to ease your symptoms and prevent the bleeding from getting worse. If so, you might be prescribed one of more of the following:

In more severe cases, emergency surgery is needed to stop the bleeding, relieve pressure on your brain, and get rid of blood that's collected in areas where it shouldn't be. Your doctor may need to act quickly to prevent complications.

Everyone's recovery is different. How well you heal from a brain hemorrhage depends on many factors, including your general health, the size of the hemorrhage, where it is in your brain, and how quickly it's discovered and treated.

A brain hemorrhage is a medical emergency. Getting diagnosed and starting treatment right away can greatly improve your outlook. Call 911 or go to the hospital if you start having any symptoms of a brain bleed.

A brain bleed, also known as a brain hemorrhage, refers to bleeding between the brain tissue and the skull or inside the brain tissue. This is a life-threatening condition that requires immediate medical attention. Brain bleeds can limit the oxygen supplied to the brain, causing headaches, nausea, vomiting, tingling in the extremities, or facial paralysis.

Most of the intracerebral hemorrhages that suddenly occur in children are due to anomalies in the blood vessels. Other possible causes include blood diseases, brain tumors, septicemia, or the use of alcohol or illicit drugs.

A brain hemorrhage can cause a range of different symptoms. These symptoms may include sudden tingling, weakness, numbness, or paralysis of the face, arm, or leg. This is most likely to occur on one side of the body only.

People can recover from a brain hemorrhage, although it is vital that they receive the correct treatment as soon as possible. Rehabilitation can help an individual adjust to life after a brain hemorrhage.

According to the American Association of Neurological Surgeons, about 1.7 million traumatic brain injuries occur every year in the U.S. About 5.3 million people have a disability due to a previous brain injury.

It is important that people protect themselves against the risk of traumatic brain injury. Wearing seatbelts in cars or helmets when riding bikes or motorcycles are easy ways to protect the head and brain.

It is also important to avoid smoking, which is a significant risk factor for stroke. The toxins in tobacco damage the cardiovascular system and can lead to plaque buildup in the arteries, making them narrower and more at risk of stroke.

People with diabetes need to make sure that they keep blood sugar levels under control. Many people with diabetes also have high blood pressure, high cholesterol, and may be overweight, all of which are risk factors for stroke.

Excess body weight can lead to raised blood pressure, diabetes, heart disease, and stroke. People can try to get moving and stay active as physical activity not only helps to shift unwanted weight but can also contribute to lowering the risk of stroke.

However, wearing protection during activities that may risk traumatic brain injury, such as cycling, as well as engaging in a healthful, active, smoke-free lifestyle can reduce the risk of a brain hemorrhage.

An intracranial hematoma is a collection of blood within the skull. The blood may collect in the brain tissue or underneath the skull, pressing on the brain. It's usually caused by a blood vessel that bursts in the brain. It also may be caused by a head injury due to a car accident or fall.

Some head injuries, such as one that causes only a short period of unconsciousness, can be minor. However, an intracranial hematoma is potentially life-threatening. It usually requires immediate treatment. This might include surgery to remove the blood.

Symptoms of an intracranial hematoma may develop right after a head injury, or they may take weeks or longer to appear. There may be a period of time without symptoms after a head injury. This is called the lucid interval.

If you don't notice symptoms right after a hit to the head, watch for physical, mental and emotional changes. For example, if someone seems fine after a head injury and can talk but later becomes unconscious, seek immediate medical care.

And even if you feel fine, ask someone to watch you. Memory loss after a blow to your head can make you forget about the blow. Someone you tell might be more likely to recognize the warning signs and get you medical attention.

The most common cause of an intracranial hematoma is a head injury. A head injury that causes bleeding within the skull may result from motor vehicle or bicycle accidents, falls, assaults, and sports injuries.

A subdural hematoma occurs when blood vessels burst between the brain and the outermost of three protective layers that cover the brain. This outermost layer is called the dura mater. The leaking blood forms a hematoma that presses on brain tissue. A hematoma that gets bigger can cause gradual loss of consciousness and possibly death.

An epidural hematoma occurs when a blood vessel bursts between the outer surface of the dura mater and the skull. Blood then leaks between the dura mater and the skull to form a mass that presses on brain tissue. The most common cause of an epidural hematoma is a head injury. This type also is called an extradural hematoma.
