Subdural Hematoma Causes and Risk Factors

Subdural Hematoma Causes and Risk Factors A subdural hematoma happens when blood gathers between the brain’s covering and the brain itself. It’s often caused by head injuries from accidents, falls, or hits. But, other things also play a big part in getting this condition.

Older people and those with brain injuries as they age are more at risk. Taking blood thinners also makes it more likely to get this condition.

Knowing why subdural hematomas happen helps us see who’s at risk. The Mayo Clinic says people over 60, those who drink too much alcohol, and those on blood thinners are more likely to get it. The American Association of Neurological Surgeons talks about how common and serious it is in older folks.

Studies in The Lancet give us more details on who gets it and how well they do with treatment. This shows how important it is to catch it early and act fast.

By understanding and tackling the causes and risks of subdural hematomas, we can help prevent it and make health care better for those at risk.

What is a Subdural Hematoma?

A subdural hematoma is a serious condition. It happens when blood gathers on the brain’s surface. This can put a lot of pressure on the brain and harm it.

Definition and Explanation

It’s said by the National Institute of Neurological Disorders and Stroke. A subdural hematoma happens when blood vessels break between the brain and its outer covering. This can be from a head injury or other bleeding causes. Subdural Hematoma Causes and Risk Factors

Types of Subdural Hematomas

There are three main types of subdural hematomas:

• Acute Subdural Hematoma: This type forms quickly after a bad head injury. It needs quick medical help.
• Subacute Subdural Hematoma: This type shows symptoms over days to weeks after a less severe injury. It starts slower than acute ones.
• Chronic Subdural Hematoma: This type takes weeks to months to form. It can happen from minor head injuries or repeated head blows.

Symptoms of Subdural Hematoma

Subdural Hematoma Causes and Risk Factors Subdural hematoma symptoms depend on the type and size of the bleed. Common signs include headaches, feeling confused, and being very sleepy. Bad cases can lead to not waking up, having seizures, and feeling weak. The Cleveland Clinic says how these symptoms grow can help doctors figure out what to do next.

Subdural Hematoma Causes and Risk Factors Knowing the difference between an acute and chronic subdural hematoma is key. Spotting the signs early can help with the right treatment.

Head Injuries Leading to Subdural Hematoma

Head injuries often cause subdural hematoma. These injuries come from big hits to the head. Knowing what causes them helps us prevent and treat them early.

Trauma and Accidents

Car crashes are a big reason for head injuries. The crash can hurt blood vessels in the head. Sports like football and boxing can also cause these injuries.

The CDC says many people go to the hospital for head injuries. This shows we need to use safety gear and follow safety rules.

Falls and Impacts

Falls are a big problem for older people. They can cause a type of brain injury. Even small falls can lead to big problems.

The Brain Injury Association says we should prevent falls. The National Safety Council says we should make homes safe, especially for older people.

Medical Conditions and Their Role in Subdural Hematomas

Subdural hematomas can happen from many medical issues. These include problems with blood clotting and blood vessels. Taking blood thinners and having chronic diseases can make the risk higher.

Blood Thinners and Anticoagulants

Medicines to prevent blood clots can make bleeding in the brain more likely. This is known by the American Heart Association. They say that taking blood thinners can lead to subdural hematomas. People on these medicines need close watch to avoid bleeding risks.

Chronic Conditions

People with long-term health issues like high blood pressure, diabetes, and blood clotting problems are at higher risk. Managing these conditions often means taking medicines that affect blood clotting. Harvard Medical School talks about the need for careful treatment planning.

A study in the Journal of the American Medical Association (JAMA) shows how chronic diseases can lead to bleeding in the brain. This includes both spontaneous and injury-caused subdural hematomas.

Causes for Subdural Hematoma

The etiology of subdural hematoma covers many reasons. It can come from a simple bump on the head to a big accident. Often, it’s because of blood clotting problems or other health issues.

Young people often get it from big crashes or sports injuries. But older folks might get it from a small fall or a minor bump. Sometimes, it happens without any clear reason, making it hard to figure out and treat.

Doctors need to know about these risks to help prevent serious problems. People taking blood thinners are more at risk and need close checks. Conditions like high blood pressure and diabetes can also make it more likely to get a subdural hematoma.

Groups like Medscape, the National Institutes of Health (NIH), and the World Health Organization give us important info. They help doctors and everyone else understand head injury causes and brain hemorrhage causes.

Aging and Its Influence on Subdural Hematoma Risk

Aging makes people more likely to get subdural hematomas. It changes how these injuries happen and how bad they can be. Knowing this helps us prevent and treat them in older people.

Natural Age-Related Changes

As people get older, their brains shrink. This shrinkage makes it easier for the brain to move inside the skull. Even a small bump can cause an elderly brain injury.

The aging brain also has less blood flow. This makes getting a geriatric subdural hematoma more likely. Experts say we need to watch closely for signs of this injury in older people.

Bone Density and Fragility

Older people often have less dense bones and they break easily. This makes them more likely to fall. Falling is a big reason for geriatric subdural hematomas.

The National Osteoporosis Foundation says older adults with osteoporosis are more likely to fall and get hurt. This is because they are more fragile.

Here’s how aging affects the risk of getting a subdural hematoma:

Alcohol and Substance Abuse as Risk Factors

Drinking too much alcohol and using drugs can make getting a subdural hematoma more likely. Using alcohol and drugs often can hurt your brain in many ways. A big worry is alcohol-induced brain injury. This means how too much alcohol can damage your brain’s structure and how it works.

Subdural Hematoma Causes and Risk Factors People who use drugs may fall more because they move and think less clearly. This makes them more likely to get hurt. Also, substance abuse and head trauma often happen together. This is because being under the influence can lead to dangerous situations and getting hurt.

Using drugs for a long time can also change how your body works. For example, it can mess up how your blood clots. The Substance Abuse and Mental Health Services Administration (SAMHSA) says we should work on fixing substance use disorders to prevent these injuries.

Studies in Alcohol Research Current Reviews show how long-term alcohol use affects the brain. They stress the need for stopping problems before they start. Also, Journal of Neurotrauma talks about how substance abuse and traumatic brain injuries are connected. This shows we must keep spreading the word and have strong plans to prevent these issues.

1. An increased chance of falling and getting hurt because of poor motor skills and judgment.
2. Changes in the brain and problems with blood clotting that make getting a hemorrhagic injury more likely.
3. The need for a full plan to prevent these problems, including handling substance abuse.

Genetic Predisposition

It’s important to know how genes affect subdural hematoma in families with brain health issues. Genes can make some people more likely to get subdural hematomas. This is true for those with a family history of brain bleeds or aneurysms.

If your family has had brain aneurysms or blood disorders, watch your health closely. Seeing a doctor often is a good idea to catch problems early. The U.S. Library of Medicine’s Genetics Home Reference says we’re learning more about genes and subdural hematomas. This means we need to keep up with new info.

The International Journal of Stroke found that genes can raise the risk of subdural hematomas. Rare but serious, familial cerebral aneurysms show why genetic advice and ongoing health checks are key.

GeneReviews® gives deep looks into genes linked to bleeding strokes. Knowing about these genetic traits helps families and doctors handle risks from genes in subdural hematoma.

Symptoms and Early Detection

It’s very important to spot subdural hematoma early. Knowing the signs can really help. Look out for changes in how someone thinks and moves.

Cognitive and Physical Signs

Early signs of brain hemorrhage and neurological warning signs are key to watch for. These signs include memory loss, getting confused, and changes in personality. These changes can make everyday tasks hard and affect how well someone feels. Subdural Hematoma Causes and Risk Factors

Look for headaches, speech that’s hard to understand, and feeling weak on one side of the body. Seizures are also a big sign that needs quick action. These symptoms can show up right after a bump on the head or can wait a bit.

When to Seek Medical Help

The American Stroke Association says to get medical help fast if you see any neurological signs, especially after a head injury. Don’t ignore these signs, even if there’s no clear injury. Getting help early, like from Johns Hopkins Medicine, is key to getting the right treatment.

Here’s a table with important symptoms:

Subdural Hematoma Causes and Risk Factors Groups like the Neurocritical Care Society help spread the word about catching subdural hematoma early. Knowing the signs and how serious they are can really help save lives and improve health.

Diagnostic Methods for Subdural Hematoma

Doctors use many ways to find a subdural hematoma. These include imaging tests and checking the brain. These steps help find out if someone has a hematoma and how bad it is.

Imaging Techniques

CT scans and MRI are key for finding subdural hematomas. A CT scan is often the first test because it shows bleeding fast. It also tells how big the hematoma is.

MRIs give more details. They show things that CT scans might miss. This is important for checking the brain in detail.

Neurological Assessments

Checking the brain with tests is also important. Doctors use the Glasgow Coma Scale to see how bad the injury is. These tests check thinking, moving, and being awake.

Subdural Hematoma Causes and Risk Factors Using CT scans, MRIs, and brain tests together is key. It helps doctors know what to do next. This might mean surgery. Following certain guidelines makes sure everyone is treated the same way.

Treatments and Medical Interventions

Treatment for subdural hematoma depends on how bad it is and the details of each case. For small or mild cases, doctors might just watch and give medicine. This is done to keep an eye on the condition without surgery right away.

For big or fast-growing hematomas, surgery is needed to prevent brain damage. Surgeons might do a craniotomy or burr hole drainage. A craniotomy means taking part of the skull off to drain the blood. Burr hole drainage makes a small hole in the skull to lower pressure and remove the blood clot.

Doctors look at many things to decide the best treatment. These include the size and spot of the hematoma, the patient’s symptoms, health, and surgery risks. Studies are being done to make treatments less invasive and better. Important medical journals share findings on the best ways to treat subdural hematoma.

They also talk about new ways to help patients after they’re diagnosed. This keeps doctors up-to-date with the latest in treating this condition.
