Who is most likely to develop a subdural hematoma?
Younger men are most likely to get these types of injuries. Older adults are at higher risk for a subdural hematoma, even with mild head injury. This is because the veins surrounding the brain are more likely to tear. About a third of subdural hematomas happen in older adults. In babies, subdural hematomas are often from shaken baby syndrome.
Is there a cure for a subdural hematoma?
Treatment of subdural hematomas depends on their severity. Treatment can range from watchful waiting to brain surgery. In small subdural hematomas with mild symptoms, doctors may recommend no specific treatment other than observation. Repeated head imaging tests are often performed to monitor whether the subdural hematoma is improving.
What is the mortality rate for subdural hematoma (SDH)?
The mortality rate for patients with an acute SDH ranges from 50 percent to 90 percent. A significant percentage of these deaths result from the underlying brain injury and pressure on the brain that develops in the days after injury. Approximately 20 percent to 30 percent of patients will recover full or partial brain function.
What should you know about subdural hematomas?
Symptoms can include any combination of the following:
- Headaches: This is the most common symptom of a subdural hemorrhage because the pressure from the blood on the brain is likely to cause pain.
- Dizziness
- Lethargy
- Loss of consciousness: When a subdural hemorrhage is large, it can disrupt the normal functioning of the brain.

What are the long term effects of a subdural hematoma?
Many people are left with some long-lasting problems after treatment for a subdural haematoma. These can include changes to your mood, concentration or memory problems, fits (seizures), speech problems, and weakness in your limbs. There's also a risk the haematoma could come back after treatment.
Can you fully recover from a subdural hematoma?
As a general rule of thumb, adults experience most of their recovery within six months, while children recover more quickly and more completely. Seizure, which can most often be controlled with medication, is a common long-term complication.
Is a subdural hematoma fatal?
A subdural haematoma is a serious condition that carries a high risk of death, particularly in older people and those whose brain was severely damaged. Acute subdural haematomas are the most serious type because they're often associated with significant damage to the brain.
What is the most common cause of subdural hematomas?
Subdural haematomas are usually caused by a head injury. Head injuries that cause subdural haematomas are often severe, such as from a car crash, fall or violent assault. Minor bumps to the head can also lead to a subdural haematoma in a few cases.

The three types of subdural hematomas are:Acute. This most dangerous type is generally caused by a severe head injury, and signs and symptoms usually appear immediately.Subacute. Signs and symptoms take time to develop, sometimes days or weeks after the injury.Chronic.
How long does it take for a subdural hematoma to resolve?
The subdural hematoma will gently drain away within two to four days.
How do they fix a subdural hematoma?
A craniotomy is the main treatment for subdural haematomas that develop soon after a severe head injury (acute subdural haematomas). During the procedure, the surgeon creates a temporary flap in the skull. The haematoma is gently removed using suction and irrigation, where it's washed away with fluid.
Can subdural hematoma cause permanent damage?
Yes, a subdural hematoma can be a serious event. Occasionally, the bleed is slow and the body is able to absorb the pooled blood. However, if the hematoma is severe, the buildup of blood can cause pressure on the brain. This pressure can lead to breathing problems, paralysis and death if not treated.
Can elderly survive from subdural hematoma?
It is generally accepted that elderly patients who suffer from an acute subdural hematoma should not be treated surgically, as few survive and even fewer recover to an independent life.
What is considered a large subdural hematoma?
According to the current guidelines, an ASDH with a thickness greater than 10 mm or a midline shift greater than 5 mm on computed tomographic (CT) scan should be surgically evacuated, regardless of the patient's Glasgow Coma Scale (GCS) score.
What is the chance of surviving a brain bleed?
Intracerebral hemorrhage (ICH) accounts for 10% to 15% of all stroke cases and is associated with a high risk of death and disability. The 30-day mortality in patients with nontraumatic ICH is about 40%, and 12% to 39% of surviving patients are functionally independent poststroke.
Is subdural hematoma a traumatic brain injury?
Because a subdural hematoma is a type of traumatic brain injury (TBI), they share many symptoms. Symptoms of a subdural hematoma may appear immediately following trauma to the head, or they may develop over time – even weeks to months.
Can a head injury affect you years later?
What's more, it has become increasingly recognized that the effects from head injuries are long-lasting. New research led by the Perelman School of Medicine at the University of Pennsylvania shows that a single head injury could lead to dementia later in life.
Can a subdural hematoma recur?
Subdural hematomas commonly recur after surgical evacuation, at a rate of 2% to 37%. Risk factors for recurrence can be patient related, radiologic, or surgical. Patient-related risk factors include alcoholism, seizure disorders, coagulopathy, and history of ventriculoperitoneal shunt.
Is a subdural hematoma considered a stroke?
If a subdural hemorrhage involves significant amounts of blood, the pressure can cause a stroke. In severe cases, significant pressure can lead to loss of consciousness or even death. This can happen if the blood is located near the brainstem, which controls breathing and other important automatic functions.
Are subdural hematomas serious?
Subdural hematomas can be life-threatening, especially when they occur after a serious brain injury. Recovery after any severe brain injury is varied.
What is the procedure to remove a subdural hematoma?
A surgical procedure called a craniotomy may be used to remove a large subdural hematoma. It’s normally used to treat acute subdural hematomas. In this procedure, your surgeon removes a part of your skull in order to access the clot or hematoma. They then use suction and irrigation to remove it.
How do burr holes work?
A burr hole can be used to drain chronic subdural hematomas as well as acute ones that are smaller than one centimeter at the thickest point. First, your surgeon creates small holes in your skull and then places rubber tubes in them. The blood from the hematoma drains out through these holes.
What is the most dangerous type of subdural hematoma?
If you sustain a major brain injury, this area can fill with blood and cause life-threatening symptoms. This is called an acute subdural hematoma. It’s the most dangerous type of subdural hematoma. Acute subdural hematomas are usually caused by: a car accident. a blow to the head.
What is subdural hematoma?
A subdural hematoma occurs when blood collects on your brain’s surface beneath the skull. Subdural hematomas can be life-threatening. They usually result from a head injury. Subdural hematomas are either acute or chronic. Acute subdural hematomas commonly form because of a severe head injury. Approximately 20 to 30 percent ...
Why do older people have subdural hematomas?
Chronic subdural hematomas are usually caused by mild or repeated head injuries. These are common in older adults who repeatedly fall and hit their heads. Some chronic subdural hematomas occur with no apparent cause. The higher rate of this condition in older adults may also be because the brain shrinks as people age.
How to diagnose subdural hematoma?
A subdural hematoma can be diagnosed using imaging tests, such as a CT or MRI scan. These scans provide your doctor with an in-depth look at your:
What Is a Subdural Hematoma?
A subdural hematoma is a collection of blood outside the brain. They’re usually caused by serious head injuries. Bleeding and added pressure on the brain from a subdural hematoma can be life-threatening. Some stop and go away suddenly; others need surgical drainage.
How long does it take for a subdural hematoma to show symptoms?
In very slow-growing subdural hematomas, there may be no noticeable symptoms for more than 2 weeks after the bleeding starts.
Why is the skull removed?
A larger section of the skull is removed, to allow better access to the subdural hematoma and reduce pressure. The removed skull is replaced shortly after the procedure. Craniectomy. A section of the skull is removed for an extended period of time, to allow the injured brain to expand and swell without permanent damage.
Why are elderly people at higher risk for subdural hematoma?
Elderly people are at higher risk for chronic subdural hematoma because brain shrinkage causes these tiny veins to be more stretched and more vulnerable to tearing.
What is the procedure to treat subdural hematoma?
Surgeons can use various techniques to treat subdural hematomas: Burr hole trephination.
What is a sudden blow to the head called?
The sudden blow to the head tears blood vessels that run along the surface of the brain. This is referred to as an acute subdural hematoma. People with a bleeding disorder and people who take blood thinners are more likely to develop a subdural hematoma.
What is the outermost layer of a subdural hematoma?
In a subdural hematoma, blood collects between the layers of tissue that surround the brain. The outermost layer is called the dura. In a subdural hematoma, bleeding occurs between the dura and the next layer, the arachnoid.
What is a chronic subdural hematoma?
A chronic subdural hematoma (SDH) is a collection of blood on the brain’s surface, under the outer covering of the brain ( dura ).
How to prevent subdural hematoma?
You can protect your head and reduce your risk of chronic SDH in several ways. Wear a helmet when riding a bicycle or motorcycle. Always fasten your seat belt in the car to decrease your risk of a head injury during an accident.
How do you know if you have a hematoma?
Some symptoms occur more often than others. Up to 80 percent of people with this type of hematoma have headaches. If your clot is large, loss of the ability to move (paralysis) can occur.
What is the best treatment for seizures?
Your doctor will focus on protecting your brain from permanent damage and making symptoms easier to manage. Anticonvulsant drugs can help reduce the severity of seizures or stop them from occurring. Drugs known as corticosteroids relieve inflammation and are sometimes used to ease swelling in the brain.
How to treat SDH?
The procedure involves making tiny holes in the skull so blood can flow out. This gets rid of pressure on the brain. If you have a large or thick clot, your doctor can temporarily remove a small piece of skull and take out the clot. This procedure is called a craniotomy.
What are the factors that increase the risk of chronic SDH?
Heavy drinking for several years is another factor that increases your risk for chronic SDH. Other factors include using blood-thinning medications, aspirin, and anti-inflammatory medications for a long time.
Where does SDH occur?
The bleeding that leads to a chronic SDH occurs in the small veins located between the brain’s surface and dura. When they break, blood leaks over a long time and forms a clot. The clot puts increasing pressure on your brain. If you’re 60 years of age or older, you have a higher risk for this type of hematoma.
