What Are The Symptoms Of Subdural Hematoma

Causes of Brain Hemorrhages

Because a subdural hematoma is a type of traumatic brain injury , 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.

Signs and symptoms of a subdural hematoma include:

  • Headache that doesnt go away.
  • Confusion and drowsiness.
  • Slurred speech and changes in vision.
  • Dizziness, loss of balance, difficulty walking.
  • Weakness on one side of the body.
  • Memory loss, disorientation, and personality changes, especially in older adults with chronic subdural hematoma.
  • Enlarged head in babies, whose soft skulls can enlarge as blood collects.

As bleeding continues and the pressure in the brain increases, symptoms can get worse. Symptoms, at this point, include:

  • Paralysis.
  • Breathing problems.
  • Loss of consciousness and coma.

Sometimes people have no symptoms immediately following a head injury. This is called a lucid interval. They develop symptoms days later. Also, its important to know that subdural hematomas that develop more slowly might be mistaken for other conditions, such as a brain tumor or stroke.

What Are The Causes Of Intracranial Hemorrhage

Causes can include:

  • Trauma, such as a head injury

  • Problems with abnormal blood vessels in the brain, such as:

  • An abnormal formation of blood vessels

  • A balloon-like bulge in the wall of a blood vessel in the brain

  • Weakened blood vessels that occur with some brain tumors

  • Sickle cell disease

  • Diseases that make your child more prone to bleed such as hemophilia.

  • Disease of the brain blood vessels such as Moyamoya disease.

  • High blood pressure.

  • In up to 1 in 5 children, there is no cause.

    Are Subdural Hematomas Serious

    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.

    Because you dont immediately know how severe a brain bleed is until further testing, all blows to the head should be considered a serious event. If you hit your head, get checked out at a hospital.

    What Treatments Are Available

    Treatment may include lifesaving measures, symptom relief, and complication prevention. Once the cause and location of the bleeding is identified, medical or surgical treatment is performed to stop the bleeding, remove the clot, and relieve the pressure on the brain. If left alone the brain will eventually absorb the clot within a couple of weeks however the damage to the brain caused by ICP and blood toxins may be irreversible.

    Generally, patients with small hemorrhages and minimal deficits are treated medically. Patients with cerebellar hemorrhages who are deteriorating or who have brainstem compression and hydrocephalus are treated surgically to remove the hematoma as soon as possible. Patients with large lobar hemorrhages who are deteriorating usually undergo surgical removal of the hematoma.

    Medical treatment The patient will stay in the stroke unit or intensive care unit for close monitoring and care.

    Surgical treatment The goal of surgery is to remove as much of the blood clot as possible and stop the source of bleeding if it is from an identifiable cause such as an AVM or tumor. Depending on the location of the clot either a craniotomy or a stereotactic aspiration may be performed.

    How Will I Be Treated

    Pin on Neuroscience


    When admitted to hospital with a brain haemorrhage, if you’re taking anticoagulants, you will be immediately prescribed medication to reverse those effects. If you’re also diagnosed with high blood pressure, you will be given medication to bring it down.

    After an SAH a lack of blood supply to the brain can lead to further brain damage, called cerebral ischaema. To prevent this, you may be given a drug called nimodipine for about three weeks.Pain relief

    Morphine or paracetamol with codeine may be given to you to help with the severe headache associated with an SAH.


    Some people develop epilepsy after a haemorrhagic stroke. There is a range of different type of medication you may be given to treat it.

    See our page Seizures and epilepsy after stroke for more information.

    Surgery to relieve pressure on the brain

    Emergency surgery is sometimes needed to remove blood, to relieve any pressure that has built up, or to repair the blood vessels. This is usually done with a procedure called a craniotomy. This operation should be carried out by a neurosurgeon.

    During the operation, a small piece of skull is cut away so the surgeon can access the cause of the bleeding. They can then repair any damaged blood vessels and ensure there are no blood clots that could restrict the flow of blood in your brain. If a blood clot has formed, it may be removed. After the bleeding has stopped, the piece of skull can be replaced.

    What Are The Risk Factors Associated With A Brain Stroke

    Some people are at a higher risk of developing a blood clot in the brain due to certain risk factors.

    Blood clots become more common as people get older, especially those above the age of 65.

    You might be at high risk if:

    People are at a risk of developing blood clots in the brain if:

    • They have a family history of blood clots
    • They smoke or consume recreational drugs
    • They suffer from hypertension
    • They suffer from autoimmune diseases
    • They suffer from heart diseases like heart failure, heart defects, heart infection or abnormal heart rhythm, such as atrial fibrillation
    • They have recently given birth

    Blood Clot In The Brain: Symptoms Causes And Treatment

    The brain is considered to be one of the most vital organs in the human body. The human brain serves as the nervous systems command center. This organ is the seat of intelligence, thoughts interpreter of the senses, initiator of body movement, and controller of behavior. Blood clot in the brain could affect these functions.

    A stroke, also known as a brain attack, is a major health threat caused by a blood clot in the blood vessels that supply the brain. These clots can cause speech impairment, inability to move or feel one side of your body, or other effects depending on which portion of the brain is affected.

    Why Is A Subarachnoid Hemorrhage Life

    If a brain aneurysm ruptures or an artery that passes over the surface of the brain bursts, blood flows into the fluid-filled space around the brain. Doctors call this area the “subarachnoid space.” Bleeding into this space is called a subarachnoid hemorrhage.

    Blood can then quickly spread in this space and put pressure on the whole brain. This means that even parts of the brain that aren’t very close to the bleeding blood vessel are damaged. The bleeding quickly causes a severe headache. Left untreated, it often leads to unconsciousness and life-threatening complications like an irregular heartbeat and respiratory arrest .

    The brain damage can cause long-term or permanent problems in everyday life, or lead to the need for nursing care for instance because of speech problems or paralysis.

    High Blood Pressure: How It Can Damage the Brain

    Not all brain bleed after strokes cause a worse outcome than the original stroke. In fact, small amounts of blood leaking out after a stroke may be a sign that blood is flowing again in that part of the brain, signaling a better outcome. Many small brain bleeds after strokes may go undetected, because patients may not feel any worse with brain bleed than how they felt with the initial stroke.

    In general, if the bleeding occupies 30% or more of the area of the brain affected by the stroke, the outcome will likely be worse. The larger the bleeding, the worse the expected outcome can be.

    The location of the brain bleed and whether it is pushing on the surrounding brain tissue also makes a significant difference in the outcome. When the bleeding is in a confined area, it generates higher pressure and pushes on a part of the brain not affected by the initial stroke. That can lead to worsening symptoms, as the previously normal part of the brain begins to deteriorate with pressure.

    What Does Rehabilitation After A Brain Bleed Entail

    The goals of long-term treatment are to help you regain the functions needed for daily living, as much and as soon as possible, and to prevent future brain hemorrhages. Rehabilitation and recovery time vary according to each persons unique brain bleed and the extent of rehabilitation possible.

    Long-term rehabilitation treatment may include:

    • Physical therapy.

    Carotid Angioplasty And Stenting

    An alternative, new form of treatment, carotid angioplasty and stenting, shows some promise in patients who may be at too high risk to undergo surgery. Carotid stenting is a procedure in which a tiny, slender metal-mesh tube is fitted inside your carotid artery to increase the flow of blood blocked by plaques. The stent is inserted following a procedure called angioplasty, in which the doctor guides a balloon-tipped catheter into the blocked artery. The balloon is inflated and pressed against the plaque, flattening it and re-opening the artery. The stent acts as scaffolding to prevent the artery from collapsing or from closing up again after the procedure is completed.

    Other Reasons To Cause Vertebrobasilar Circulatory Disease

    Along with Atherosclerosis and other aforementioned reasons, you may suffer from Vertebrobasilar Circulatory Disease because of following major health disorders-

    • Heart attack, cardiac arrest or stroke problems
    • Dissection or tear in the walls of arteries
    • Physical trauma or physical injury
    • Diseases associated with connective tissues, like lupus or scleroderma
    • Vasculitis or hypersensitivity vasculitis

    How Is A Bleed In The Brain Diagnosed


    Your consultant will examine you, take a history of what happened, and suggest some tests.

    One of the tests will likely be a scan of your head, either a CT or MRI scan. Sometimes these scans may also reveal the underlying cause of the bleed.

    Once bleeding has been confirmed, and the cause found, your consultant will work with you to create a treatment plan.

    This plan will aim to reduce and manage any symptoms you have left after the bleed, to ensure you retain your quality of life.

    The plan will also aim to reduce the chance of another bleed occurring.

    Depending on the cause of the bleed, this treatment might involve lifestyle changes, changes to existing or new medication, or even surgery.

    Rest assured that your needs will be at the centre of the treatment plan.

    Symptoms Of A Brain Bleed

    Symptoms of a brain hemorrhage vary depending on the location and severity of the bleeding, and how much brain tissue is affected. Symptoms may appear suddenly or gradually over time. Because many of these symptoms overlap with other conditions, its important to seek immediate medical attention to diagnose whether you have a brain bleed.

    Common symptoms of a brain hemorrhage include:

    • Sudden, severe headache

    • Seizures, with no previous history of seizures

    How Is Bleeding In The Brain Treated

    Treatment of brain bleeds starts with a careful analysis of the brain through various imaging tests to determine the locations of internal bleeding. Apart from the MRI and CT Scans, which reveal the position of the bleeding, a neurological examinations may be performed to determine if there is any swelling in the optic nerves. Treatments will vary by extent, cause, and location of the hemorrhage. Some diagnoses will require surgery to stop bleeding and to alleviate swelling. Others will require medications such as anticonvulsants that control seizures, diuretics that reduce swelling, and corticosteroids and painkillers.

    What Causes A Brain Hemorrhage

    Many of us know that a brain hemorrhage means there is bleeding in the brain, but what actually causes one?

    Its helpful to understand that the bleeding can happen either inside the brain or outside of the brain but still within the skull. A hemorrhage can directly injure the brain or secondarily damage the brain through pressure reducing oxygen and blood flow to the compressed area. This causes further injury and killing brain cells.

    Brain hemorrhages have a number of causes, including:

    What Is A Brain Bleed

    2-Minute Neuroscience: Brain Aneurysms

    To most people, a brain bleed simply means any bleed inside your head. However, a doctor and specifically doctors who treats brain bleeds would say that a brain bleed is too broad of a term. These doctors further describe brain bleeds by their exact location.

    To better understand brain bleeds, its important to have a basic understanding of the different types. First, there are two main areas where bleeding can occur bleeding can occur either within the skull but outside of the brain tissue, or inside the brain tissue. These areas are further divided as follows:

    Bleeding within the skull but outside of the brain tissue

    The brain has three membranes layers that lay between the bony skull and the actual brain tissue. The purpose of the meninges is to cover and protect the brain. Bleeding can occur anywhere between these three membranes. The three membranes are called the dura mater, arachnoid, and pia mater.

    • Epidural bleed : This bleed happens between the skull bone and the utermost membrane layer, the dura mater.
    • Subdural bleed : This bleed happens between the dura mater and the arachnoid membrane.
    • Subarachnoid bleed : This bleed happens between the arachnoid membrane and the pia mater.

    Brain bleeds can occur within the meninges, which is the area inside the skull but outside the actual brain tissue.

    Bleeding inside the brain tissue

    Two types of brain bleeds can occur inside the brain tissue itself intracerebral hemorrhage and intraventicular hemorrhage.

    How Is Intracranial Hemorrhage Diagnosed

    Intracranial hemorrhage is an emergency. Your doctor will advise you to take your child to the closest emergency room if intracranial hemorrhage is suspected. Your child may be seen by a pediatric neurologist or neurosurgeon. These are doctors with special training to find and treat problems that affect the brain and nervous system. The doctor will ask about your childs health history and symptoms. The doctor will also examine your child. Tests will be done too. These can include:

    • MRI or CT scan. These give detailed pictures of the brain. They are used to help check for bleeding. During the test, fluid called contrast dye may be used to make the blood vessels and brain easier to see.

    • Angiography. This test takes pictures of the blood vessels in the brain. During the test, a thin tube called a catheter is guided into the blood vessels leading to the brain. Contrast dye is sent through the tube. This is to make the blood vessels easier to see. This test can also be done with an MRI or CT scan.

    • Transcranial doppler . This test shows the flow of blood through the blood vessels in the brain. It uses harmless sound waves to form pictures of the brain and blood vessels. It’s used to monitor ongoing conditions that may worsen the bleeding.

    • Blood tests. Blood tests are done to find risk factors. The tests include platelet count and other tests to measure blood clotting.

    What Is A Subdural Hematoma

    A subdural hematoma is a collection of blood outside the brain. Theyâre 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.

    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.

    The bleeding is under the skull and outside the brain, not in the brain itself. As blood pools, however, it puts more pressure on the brain. The pressure on the brain causes symptoms. If pressure inside the skull rises to a very high level, a subdural hematoma can lead to unconsciousness and death.

    Causes Of Brain Bleeds

    Brain bleeds can be caused by various actions like increased intake of alcohol, overemphasize on exercise, chain-smoking, high cholesterol consumption, heavy nose-blowing, stress, anger, sudden shock, constant sex, and masturbation, drinking coffee constantly, stroke, excessive use of soda, and cola, constipation, traumatic brain injury after a fall, head injury, using cocaine, and a rare genetic disorder.

    The other reasons could be aging- capillaries become weak and swelling in capillaries walls, causing aneurysm, high blood pressure, people with sickle cell anemia, hemophilia, diabetes, and alcohol addicts.

    If there is a weakness in the blood vessel, the blood vessel will balloon and bulge out to be a bubble thinning the artery wall known as an aneurysm. Emotional distress or any other shocks can rupture the aneurysms to cause brain bleeds. The cause may seem simple for the brain bleeds, but the effect is heavy for those who do excessively the abovementioned actions, even after the cause and effect is discovered. It has to be rightly treated with care to reduce brain pressure.

    Blood Clots In Brain Causes

    Intracranial Hemorrhage: Symptoms, Causes, Treatment, and Diagnosis ...

    Blood clots are the bodys natural defense to damage when a blood vessel is damaged. They basically form to stop the body from bleeding out. Unfortunately, they can also form when the body thinks that a blood cell has been damaged, or if the blood cell has been damaged internallyand thats where the problems can arise.

    One of the first things to know when dealing with blood clots, is the various blood clot in brain causes. There are a number of causes of blood clots in the brainsome of which can be prevented, and other causes you can have very little control over.
