Subdural hemorrhage: Causes, Risk Factors, Symptoms, Treatment

Subdural hemorrhage

Subdural hemorrhage, also known as subdural hematoma, is a medical condition characterized by the accumulation of blood in the space between the brain and its outermost covering, known as the dura mater. This condition typically occurs as a result of trauma or injury to the head, causing blood vessels to rupture and bleed. A subdural hemorrhage can be classified into two types: acute and chronic. Acute subdural hemorrhage refers to a sudden and rapid accumulation of blood, often resulting from severe head trauma. On the other hand, chronic subdural hemorrhage develops gradually over time and is commonly seen in elderly individuals or those with a history of repeated head injuries. The symptoms of subdural hemorrhage may vary depending on its severity. Mild cases may present with headaches, confusion, and dizziness, while more severe cases can lead to seizures, loss of consciousness, or even coma. Prompt medical attention is crucial when dealing with subdural hemorrhages. Diagnosis often involves imaging tests such as CT scans or MRIs to assess the extent of bleeding and determine appropriate treatment options. Treatment for subdural hemorrhages may involve surgical intervention to remove accumulated blood or relieve pressure on the brain. In some cases, medications may be prescribed to manage symptoms and prevent complications.

Symptoms of Subdural hemorrhage

If you suspect you or someone else is experiencing Subdural hemorrhage, it is crucial to seek immediate medical attention by calling emergency services or consult with a Neurologist.


One common cause of subdural hemorrhage is head trauma or injury. This can occur due to falls, motor vehicle accidents, sports-related incidents, or any other situation where a significant impact is sustained by the head. The forceful movement of the brain within the skull can lead to blood vessels tearing and bleeding into the space between the brain and its outermost protective layer, known as the dura mater. Another cause of subdural hemorrhage is related to age. As individuals get older, their blood vessels become more fragile and prone to rupture. This makes older adults more susceptible to experiencing a subdural hematoma even with minor head trauma. Certain medical conditions and medications can also increase the risk of developing a subdural hemorrhage. For instance, individuals with bleeding disorders or those taking anticoagulant medications may experience prolonged bleeding after head trauma, leading to the accumulation of blood in the subdural space. It's worth noting that sometimes no specific cause can be identified for a subdural hemorrhage. In such cases, it may be attributed to spontaneous bleeding from small blood vessels within the brain. Understanding these various causes of subdural hemorrhage allows healthcare professionals to take appropriate preventive measures for those at risk and provide targeted treatment for individuals who develop this condition. Early detection and intervention are crucial in ensuring optimal outcomes for patients affected by this potentially serious medical condition.

Risk Factors

Understanding the risk factors associated with subdural hemorrhage is crucial in order to prevent and manage this serious medical condition. Subdural hemorrhage occurs when blood vessels rupture between the brain and its outermost covering, causing bleeding and potentially leading to life-threatening complications. Several risk factors have been identified that can increase an individual's susceptibility to subdural hemorrhage. One significant risk factor is advanced age, as older adults tend to have thinner blood vessels that are more prone to rupture. Additionally, individuals who have a history of head trauma or previous episodes of subdural hemorrhage are at a higher risk. Certain medical conditions can also contribute to the development of subdural hemorrhage. These include hypertension (high blood pressure), coagulation disorders, such as hemophilia or thrombocytopenia (low platelet count), and liver disease, which can impair the body's ability to clot blood properly. Engaging in activities that carry a high risk of head injury, such as contact sports or occupations involving heavy machinery, can also increase the likelihood of experiencing a subdural hemorrhage. It is important for healthcare professionals and individuals at risk to be aware of these factors in order to take appropriate preventive measures. Regular monitoring of blood pressure, prompt treatment of underlying medical conditions, and practicing safety precautions during high-risk activities can all play a significant role in reducing the incidence of subdural hemorrhages and ensuring better overall health outcomes.


Recognizing the symptoms of subdural hemorrhage is crucial for timely intervention and treatment. This condition, characterized by bleeding between the brain and its outermost covering, can have serious consequences if left untreated. One of the primary symptoms of subdural hemorrhage is a headache. This headache may be severe and persistent, often worsening over time. Other common symptoms include dizziness, confusion, and difficulty with balance or coordination. In some cases, individuals may experience seizures or loss of consciousness. It's important to note that the severity and presentation of symptoms can vary depending on the size and location of the hemorrhage. While some individuals may experience immediate symptoms following a head injury or trauma, others may develop symptoms gradually over time. If you or someone you know is experiencing any of these symptoms after a head injury or trauma, it is imperative to seek medical attention immediately. Early diagnosis and intervention can greatly improve outcomes for individuals with subdural hemorrhage.

Accurate and timely diagnosis of subdural hemorrhage is crucial for effective treatment and management. With advancements in medical technology, healthcare professionals now have a range of diagnostic tools and techniques at their disposal to identify this condition. One of the primary methods used in the diagnosis of subdural hemorrhage is neuroimaging. Imaging techniques such as computed tomography (CT) scans or magnetic resonance imaging (MRI) can provide detailed images of the brain, allowing doctors to visualize any bleeding or blood clots in the subdural space. In addition to neuroimaging, clinical evaluation plays a vital role in diagnosing subdural hemorrhage. Healthcare providers carefully assess a patient's medical history, symptoms, and physical examination findings to help guide their diagnosis. They may look for signs such as headache, altered consciousness, neurological deficits, or other indicators that could suggest the presence of a subdural hemorrhage. Furthermore, laboratory tests may be conducted to evaluate blood clotting factors or rule out other potential causes of bleeding within the brain. It is important to note that prompt diagnosis is essential as delays can lead to worsening symptoms and potentially life-threatening complications. Therefore, healthcare professionals must remain vigilant when evaluating patients who present with symptoms suggestive of subdural hemorrhage. By utilizing a combination of neuroimaging techniques, clinical evaluation, and laboratory tests when necessary, healthcare providers can accurately diagnose subdural hemorrhage and initiate appropriate treatment strategies promptly.


When it comes to the treatment of subdural hemorrhage, prompt medical intervention is crucial. Subdural hemorrhage refers to the accumulation of blood between the brain and its outermost covering, known as the dura mater. This condition can be life-threatening and requires immediate attention. The treatment approach for subdural hemorrhage depends on various factors such as the severity of the bleeding, the patient's overall health, and any underlying conditions they may have. In mild cases, conservative management may be sufficient, which involves close monitoring of the patient's condition and administering pain relief medications. However, in more severe cases or when there is a risk of increased intracranial pressure, surgical intervention may be necessary. The main goal of surgery is to evacuate the accumulated blood and relieve pressure on the brain. This can be done through various procedures such as burr hole drainage or craniotomy. In addition to surgical intervention, other supportive measures may be employed during treatment. These can include administering medications to control seizures or reduce swelling in the brain, providing supplemental oxygen for patients with respiratory difficulties, and closely monitoring vital signs. It is important to note that subdural hemorrhage is a serious medical condition that requires specialized care from healthcare professionals. If you or someone you know experiences symptoms such as severe headache, confusion, loss of consciousness, or neurological deficits following a head injury or trauma, seeking immediate medical attention is essential for proper diagnosis and appropriate treatment.
