Subdural Hematoma: Causes & Care
Subdural Hematoma: Causes & Care A subdural hematoma happens when blood gathers between the brain and a tough outer layer called the dura mater. This usually comes from a head injury. It’s a serious issue because it can harm brain function and health. Knowing about subdural hematoma helps doctors and caregivers. Quick action can help a lot and prevent serious problems later on.
Good care and treatment for brain injuries are key. They can really change how well someone does and their life quality.
Introduction to Subdural Hematoma
A subdural hematoma is a serious condition. It happens when blood gathers between the dura mater and the brain. It’s important to understand this injury well.
Understanding Brain Injuries
Brain injuries can be many things. They can come from accidents, or from certain health issues. It’s key to know how these injuries happen and what they mean.
What is a Hematoma?
A hematoma is when blood clots outside its normal place. It can happen in muscles, organs, or under the skin. There are different kinds of hematomas, like subdural, epidural, and intracerebral.
A subdural hematoma is when blood gathers between the brain’s protective layers. This is different from an epidural hematoma, which is between the skull and the dura mater.
What is Subdural Hematoma
A subdural hematoma is when blood gathers between the brain and its outer layer. It’s a serious issue that needs quick action.
Definition and Symptoms
It happens when veins near the brain’s outer layer break. This causes blood to gather in a special space. People may feel headaches, get confused, feel dizzy, or nauseous. These feelings can get worse as the blood pressure on the brain goes up. Subdural Hematoma: Causes & Care
Types of Subdural Hematomas
There are three main kinds of subdural hematomas:
- Acute Subdural Hematoma: This type has severe symptoms right after a big head injury.
- Subacute Subdural Hematoma: Symptoms start a few days to weeks after the injury.
- Chronic Subdural Hematoma: Symptoms can show weeks to months later, often in older people or those taking blood thinners.
Both kinds of bleeding can be very dangerous. Finding and treating them quickly is key.
How Does it Affect the Brain?
Subdural hematomas put pressure on the brain. This can squeeze brain tissue and hurt how it works. In bad cases, the brain might push through the skull openings. This is very serious and can be deadly if not treated right away.
Causes of Subdural Hematoma
Subdural hematoma often comes from head trauma. It’s key to know what causes these injuries. They usually happen from falls, car crashes, or being shaken a lot. These events can tear veins between the brain and its cover. This leads to blood collecting in the subdural space and clotting.
Using blood thinners or having blood clotting problems also plays a big part. People on blood thinners or with clotting issues bleed more after an injury. This makes them more likely to get a subdural hematoma.
Subdural Hematoma: Causes & Care Drinking too much alcohol can also raise the risk. So can hits in sports like football or boxing. These repeated blows can hurt blood vessels over time. This makes getting a subdural hematoma more likely.
- Head injury causes: falls, accidents, violent shaking
- Blood thinners and coagulation disorders
- Alcohol abuse and sports-related impacts
Knowing why subdural hematomas happen helps us prevent them. It also makes diagnosing them more accurate. This is key for lowering the risks for certain people.
| Cause | Description | Effect |
|---|---|---|
| Head Trauma | Falls, vehicle accidents, violent shaking | Vein tears and blood pooling |
| Blood Thinners | Use of anticoagulants or inherent coagulation disorders | Prolonged bleeding after injury |
| Alcohol Abuse & Sports | Chronic alcohol consumption and repetitive impacts | Weakened blood vessels and increased bleeding |
Risk Factors Associated with Subdural Hematoma
It’s important to know the risks of subdural hematoma to prevent and act early. We can help those most at risk by understanding what makes them more likely to get it. This way, we can take steps to avoid health problems.
Age and Health Conditions
Older people are more likely to get subdural hematoma. This is because their brains shrink with age, leaving less space between the brain and skull. This makes blood vessels more likely to break during a bump on the head. Subdural Hematoma: Causes & Care
Also, health issues like high blood pressure and diabetes make the risk higher. These conditions make blood vessels weak and more likely to bleed easily from small injuries.
Impact of Trauma
Getting a head injury is a big risk for getting a subdural hematoma. Activities like playing contact sports, riding a motorcycle, or working in dangerous jobs increase the risk of head injuries. Even a small bump can cause serious problems if safety steps aren’t taken.
Wearing safety gear, getting proper training, and following safety rules can help reduce the risks of head injuries.
| Risk Factor | Details |
|---|---|
| Age | Increased space between the brain and skull; greater vulnerability of blood vessels. |
| Pre-Existing Medical Conditions | Conditions like hypertension and diabetes increase the fragility of blood vessels. |
| Head Trauma | High-risk activities and occupations that lead to injuries, emphasizing the importance of safety measures. |
Signs and Symptoms to Look Out For
It’s very important to spot the signs of a subdural hematoma early. Knowing the subdural hematoma warning signs helps get treatment fast. This can really help patients get better.

- Worsening headache
- Vomiting
- Seizures
Critical Warning Signs
Some signs mean you need to get medical help right away. These signs show serious brain problems and could be very dangerous. Watch out for:
- Altered consciousness
- Paralysis
- Intense headache
Knowing these signs helps us see how serious it is. This means we can act fast and might save lives.
Diagnosis of Subdural Hematoma
Diagnosing subdural hematoma needs a mix of a detailed medical history, a thorough physical check-up, and special imaging tests. This method helps find the injury accurately and plan the right treatment.
Medical History and Physical Examination
Subdural Hematoma: Causes & Care Doctors start by taking a detailed medical history to find out what might have caused the injury. They look for things like recent head blows or health issues that could lead to bleeding. This helps them spot important clues that aren’t easy to see.
Then, they do a physical check-up to see if there are signs of brain damage or too much pressure inside the skull. Checking how awake someone is, how their pupils react, and how they move is key. This tells them how serious the injury is.
Imaging Tests
Imaging tests are key to confirming a subdural bleed and seeing how bad it is. A CT scan is often the first test used. It gives quick, clear pictures of the brain, showing where and how big the bleed is. Subdural Hematoma: Causes & Care
Sometimes, an MRI brain imaging is needed too. It takes longer but shows more details, especially for chronic bleeds or small brain injuries. These tests help doctors decide the best treatment.
Treatment Options for Subdural Hematoma
Managing subdural hematoma (SDH) depends on how bad it is. First, doctors might use non-surgical ways or surgery.
Medical Management
For small SDH, doctors often choose non-surgical treatments. They watch the patient closely and use medicines to ease symptoms. Keeping an eye on the patient is key to stop things from getting worse.
The aim is to keep the patient stable without doing major surgery.
Surgical Intervention
For big SDH, surgery is often needed to ease brain pressure. Doctors use craniotomy or burr hole drainage for this. Craniotomy means taking off a part of the skull to drain the blood. Burr hole drainage makes small holes in the skull for draining.
This surgery helps stop more brain damage and can make patients feel better. The choice of surgery depends on the size, location of the bleed, and the patient’s health.
Post-Treatment Care and Recovery
After treating a subdural hematoma, it’s key to focus on care and recovery. This means doing rehabilitation and following up with doctors. Each step helps the patient get better and lowers the chance of getting hurt again.
Rehabilitation Therapies
Rehabilitation for subdural hematoma includes many therapies. These help with the healing process. They are:
- Physical Therapy: Helps improve strength, balance, and how you move. It uses exercises to make you stronger and more mobile.
- Occupational Therapy: Helps you do everyday tasks again. It makes you better at moving and adapting.
- Speech Therapy: For those who have trouble speaking or understanding speech. It aims to improve how you talk and listen.
Monitoring and Follow-Up
It’s important to keep an eye on patients after they’ve had a subdural hematoma. Regular check-ups help manage ongoing effects and catch problems early. How often you see the doctor will depend on your situation, but it usually includes:
- Neurological Assessments: Regular checks to see how your brain is working and if there are any signs of getting worse.
- Imaging Tests: Scans like CT or MRI to look for any new blood clots or other issues.
- Medication Management: Changing medicines to control symptoms or prevent problems, based on what the doctor says.
Using both rehabilitation and regular doctor visits helps a lot with getting better. It also lowers the risk of future problems. This means a better life for the patient.
Preventive Measures to Protect Brain Health
Keeping your brain safe is key for good health. Taking steps early can really help prevent brain injuries. These injuries can have big effects on your life. Here are some easy ways to help:
Safety Tips
Use safety gear every day to protect your brain. Wear helmets when you’re biking, skateboarding, or playing sports. For older people, make sure they have handrails, non-slip mats, and good lighting in places like stairs and bathrooms.
Always wear seatbelts in cars to avoid head injuries if there’s an accident.
Healthy Lifestyle Choices
Living a healthy life is just as important as wearing safety gear. Exercise, eat well, and keep your mind active to keep your brain healthy. Eating foods full of omega-3s, antioxidants, and vitamins helps your brain work better.
