A subdural hematoma is a serious condition. It happens when blood gathers between two brain layers. This can put a lot of pressure on the brain and cause damage.
Definition and Overview
“Subdural hematoma” means blood clots in the brain. It usually comes from a head injury. This injury can tear veins in the brain.
Causes of Subdural Hematoma
Many things can cause subdural hematomas. These include big and small head injuries. People at risk are older folks, those on blood thinners, or heavy drinkers.

There are two kinds of subdural hematomas. An acute one is sudden and severe, often from a big injury. A chronic one is slower and can happen after a small injury or no injury at all, especially in older people.
| Type | Characteristics | Cause |
|---|---|---|
| Acute Subdural Hematoma | Rapid onset, severe symptoms | Major head trauma |
| Chronic Subdural Hematoma | Slow onset, gradual symptoms | Minor head injury or no clear causative incident |
Symptoms of Subdural Hematoma
A subdural hematoma can show many symptoms that can get worse over time. It’s important to know these signs to get help fast.
Early Symptoms
The first signs of a subdural hematoma are often not very strong but are important. These signs include a headache, confusion, and drowsiness. Paying attention to these is key, especially after a head injury.
Progressive Symptoms
As it gets worse, more serious signs can show up. These include aphasia (trouble speaking), hemiparesis (weakness on one side), and seizures. People may also feel more dizzy and might even lose consciousness.
When to Seek Medical Attention
Get help right away if you have a head injury and show these symptoms. Or if you have them and don’t know why. Quick action is key to avoid serious problems.
| Symptom | Early Phase | Progressive Phase |
|---|---|---|
| Headache | Persistent | Severe |
| Confusion | Occasional | Frequent |
| Dizziness | Mild | Significant |
| Neurological Signs | Minimal | Pronounced (aphasia, hemiparesis, seizures) |
| Loss of Consciousness | Rare | Common |
Understanding Closed Head Injuries
A closed head injury means the skull didn’t break, but the brain hit the skull. These injuries can be mild or very serious. It’s important to know about them to prevent and treat them well.
Definition of a Closed Head Injury
A closed head injury happens when the brain hits the skull but the skull doesn’t break. These injuries can cause headaches, dizziness, and problems with thinking. They can be mild or very serious.
Common Causes
Closed head injuries often happen from a sudden hit to the head. Here are some common ways they happen:
- Falls: Older people and kids often get hurt from falling and hitting their heads.
- Motor Vehicle Accidents: Car crashes can cause serious head injuries because of the sudden stop.
- Sports Injuries: Sports like football, boxing, and soccer can lead to head injuries.
The table below shows common situations and the head injuries they might cause:
| Scenario | Potential Injury | Severity |
|---|---|---|
| Fall | Concussion | Mild to Moderate |
| Motor Vehicle Accident | Brain Contusion | Moderate to Severe |
| Sports Injury | Non-penetrating Head Injury | Mild to Severe |
Is a Subdural Hematoma a Closed Head Injury?
A subdural hematoma is usually a closed head injury. This means there’s no open wound. It happens when the skull doesn’t break, making it hard to see the injury without special tests.
This injury can cause a lot of problems. The main worry is that it can make the brain pressure go up. This high pressure can harm brain parts and cause a big emergency.
Doctors need to know the difference between open and closed head injuries. Closed injuries like a subdural hematoma need special care. Knowing this helps doctors give the right treatment fast.
| Closed Head Injury | Open Head Injury |
|---|---|
| No visible skull fracture | Accompanied by a skull fracture |
| Increased intracranial pressure | Visible external wound |
| High risk of brain trauma | Greater chance of infection |
Diagnosis of Subdural Hematoma
Doctors use several ways to find a subdural hematoma. They look at CT scans and MRI images. These tests show the brain clearly, helping find the blood clot.
A clinical examination and looking at the patient’s history are also key. These steps help tell if it’s a subdural hematoma or another injury. Doctors say these steps are very important for making treatment plans.
It’s very important to find this condition early. Using a CT scan or MRI helps doctors treat it fast. This can make a big difference in how well the patient does.
| Diagnostic Method | Description | Advantages |
|---|---|---|
| CT Scan | Computed Tomography scan providing cross-sectional brain images | Quick, widely available, and effective in detecting acute hemorrhages |
| MRI | Magnetic Resonance Imaging offering detailed brain images using magnetic fields | Precise in identifying chronic and small hematomas, no radiation exposure |
| Clinical Examination | Physical assessment and patient history evaluation | Helps differentiate from other head injuries, guides neuroimaging needs |
Treatment Options for Subdural Hematoma
Treatment for a subdural hematoma includes both medical and surgical steps. The choice depends on how bad the bleed is and the patient’s health.
Medical Interventions
First, doctors watch closely and manage symptoms. If seizures happen, they might give anticonvulsants to stop more seizures. They also work on easing pain and lowering pressure in the skull.
Surgical Options
Surgery depends on the size and where the bleed is. Burr hole surgery is used for smaller bleeds. It lets doctors remove blood through small skull openings. For bigger or harder cases, a craniotomy is needed. This means taking part of the skull off to get to the blood clots.
| Surgical Procedure | Indication | Invasiveness |
|---|---|---|
| Burr Hole Surgery | Smaller hematomas | Minimally invasive |
| Craniotomy | Larger or complex hematomas | Highly invasive |
Recovery and Rehabilitation
Getting better after surgery is important. A team of experts helps with this. They use physiotherapy, occupational therapy, and speech therapy as needed. Keeping a close eye on the patient helps adjust treatments for the best recovery.
Risk Factors for Developing Subdural Hematoma
It’s important to know what can increase the risk of getting a subdural hematoma. Elderly patients are at a higher risk because their brains are more fragile. They often fall and get small head injuries that can be very serious.
Using anticoagulation therapy also raises the risk. These medicines help prevent blood clots but can make bleeding more likely. So, even a small head injury can lead to a subdural hematoma.
Alcohol abuse is another big risk factor. Drinking too much can hurt the liver and make blood clotting poor. It also makes people more likely to fall and get hurt, which can cause head injuries.
Doing risky activities or sports can also increase the chance of getting a head injury. These injuries can be serious and lead to a subdural hematoma.
Some medical conditions and surgeries can make it harder for the body to form blood clots. This makes even small head injuries more dangerous.
| Risk Factor | Description |
|---|---|
| Advanced Age | Elderly patients have increased vulnerability to brain tissue injuries and falls. |
| Anticoagulation Therapy | Medications that prevent blood clots can increase bleeding risks with minor traumas. |
| Alcohol Abuse | Chronic alcohol consumption leads to impaired clotting and higher injury propensity. |
| Head Injury Risks | Engaging in high-risk activities or sports heightens the chances of head trauma. |
| Clotting Deficiencies | Medical conditions or surgeries affecting clot formation can raise the risk. |
Prevention of Subdural Hematomas
Keeping your brain safe is key to avoiding serious injuries. By taking simple steps every day, you can lower the chance of getting hurt. This helps keep your brain healthy.
Safety Measures
Stopping falls is a big part of staying safe. You can do this by putting grab bars in bathrooms and using non-slip mats. Also, make sure stairways are bright and well-lit.
Wearing seat belts in cars is also very important. It helps protect you in case of an accident and keeps your head safe.
When to Wear Protective Gear
Using safety gear is crucial to avoid brain injuries. Always wear helmets when you’re biking, skateboarding, or playing contact sports. Helmets help absorb shock and lessen the blow to your head.Subdural Hematoma as a Closed Head Injury
Learning about how to prevent falls and the need for safety gear is key. This is especially true for older people, athletes, and those with health issues. By being aware and safe, we can all help reduce the number of brain injuries.
