Treatment And Medication Options For Cerebral Edema

Blurry vision, brain fog, and increased ocular pressure, due to Intracranial Hypertension

Once we determine whats going on, patients will be monitored in the hospital for complications from the swelling itself, and well treat the neurological condition thats causing the edema, Balu says. Treatment is dictated by the type of neurologic injury.

If the cause is cytotoxic, doctors will look to reverse the underlying medical condition first with acute treatments, Balu says for example, by starting an intravenous delivery of hypertonic saline that increases electrolytes in the blood and pulls water out of the brain. Same for bleeding in the brain or TBI, he says. We dont necessarily treat the swelling right away because its less of a concern. Though in extreme cases, well have our colleagues do a craniectomy, where they take a portion of the skull off to let the brain swell out. And if a patient comes in with acute symptoms of a stroke, Balu says they first work to get blood flow to the brain.

Once cerebral edema has been diagnosed through a scan, a doctor may help relieve pressure by:

In extreme cases, your doctor may consider a craniectomy to relieve pressure. Controlled hyperventilation, high-dose barbiturate therapy, and moderate hypothermia are other treatments to reduce swelling.

Balu says an initial treatment of brain swelling is often a drug, such as:

Preventing cerebral edema involves taking measures to protect your head. Some options include:

What Is The Treatment For Brain Swelling

Minor cases of brain swelling due to causes such as moderate altitude sickness or a slight concussion often resolve within a few days. In most cases, however, more treatment is needed quickly.

The goal is to assure that the brain receives enough blood and oxygen to remain healthy while the swelling is relieved and any underlying causes are treated. This may require a combination of medical and surgical treatments. Prompt treatment usually results in quicker and more complete recovery. Without it, some damage may remain.

Supportive care for brain edema may include any combination of the following:

Optic Nerve Fenestration For Iih

Optic nerve fenestration is sometimes done for papilledema that is not improving with standard medical treatments and vision continues to worsen. This is basically a procedure which makes small slits in the optic nerve sheath, which encloses the optic nerves and keeps the CSF in place around them. By doing this, it can release the CSF pressure on the nerves . This procedure is only done to prevent further vision loss which isnt responding to conservative treatment, but does not typically help the headache.

Process Of Raised Intracranial Pressure

A rise in the pressure within the brain may be diffuse meaning that it is occurring throughout the cranial cavity or focal where it is only increasing in a localized area. A rise in intracranial pressure can be due to the brain expanding outwards as a result of edema or bleeding in the brain, or it can be from around the brain pushing inwards due to intracranial bleeding or hydrocephalus.

Depending on the mechanism, the blood vessels in the brain may be compressed and blood flow to the brain reduced. This starves the brain tissue of vital oxygen which results in ischemia, an inflammatory process associated with low oxygen availability. Further swelling then follows as a result of inflammation which in turn exacerbates the condition as it further contributes to a rise in intracranial pressure. A host of signs and symptoms may be seen and eventually with significant brain herniation, the brainstem may be compressed which is often life-threatening.

Causes Of Pressure On The Brain

Symptoms of a brain tumor can be general or specific. A ...

A rise in the pressure within the cranial cavity may be due to an enlarging mass or increasing quantity of fluid. This may include :

  • Cerebral edema which is swelling of the brain as the quantity of fluid in the tissue spaces or within the cells itself increases. This may be due to injury, infection, damage to blood vessels and other causes discussed under cerebral edema.
  • Hydrocephalus where there is an obstruction to the cerebrospinal fluid flow.
  • Abscess which is a localized collection of pus within the brain tissue.
  • Hematoma which is a localized accumulation of blood and hemorrhage which is bleeding in the cranial cavity. Read more on bleeding in the brain.
  • Tumors, benign or malignant, are abnormal growths which occupy space within the cranial cavity and can compress brain tissue or invade the tissue .
  • Other brain masses include :
  • Cysts hydatid , arachnoid, colloid
  • Idiopathic intracranial hypertension

    What Do Brain Tumour Headaches Feel Like

    Headaches associated with brain tumours:

    • can be throbbing or a dull ache, depending on where they are in the brain
    • occur intermittently starting gradually, but fading over a few hours
    • tend to get worse over time
    • can resemble common migraine or tension-type headaches.

    Other types of headaches

    Other types of headaches include:

    • tension headaches

    For more information about these and other headache types, see the National Headache Foundation’s Complete Headache Chart.

    Sinus Infection And Sinus Headache

    Health issues such as seasonal allergies and upper respiratory infections can cause inflammation in the nasal passages and sinuses. This can result in a sinus headache.

    A sinus headache causes a feeling of constant pressure in the front of the head. A person may also experience the sensation in the:

    Pressure In Head And Eyes

    Head pressure accompanied by eye pressure can be a sign of eye strain, allergies, or sinus infections. Migraines and other headaches can also cause eye-related symptoms.

    Some causes of head pressure dont require medical treatment. Home remedies and lifestyle changes may help to improve your symptoms.

    Tension headaches in particular have been linked to stress, poor sleep, and mental health conditions such as

    Over-the-counter pain relievers, such as aspirin, naproxen , and ibuprofen , can also help.

    What Are The Causes

    High Blood Pressure: How It Can Damage the Brain
    • Hypertension: elevated blood pressure may cause tiny arteries to burst inside the brain. Normal pressure is 120/80 mm Hg.
    • Blood thinners: drugs such as coumadin, heparin, and warfarin used to prevent clots in heart and stroke conditions may cause ICH.
    • AVM: a tangle of abnormal arteries and veins with no capillaries in between.
    • Aneurysm: a bulge or weakening of an artery wall.
    • Head trauma: fractures to the skull and penetrating wounds can damage an artery and cause bleeding.
    • Bleeding disorders: hemophilia, sickle cell anemia, DIC, thrombocytopenia.
    • Tumors: highly vascular tumors such as angiomas and metastatic tumors can bleed into the brain tissue.
    • Amyloid angiopathy: a buildup of protein within the walls of arteries.
    • Drug usage: alcohol, cocaine and other illicit drugs can cause ICH.
    • Spontaneous: ICH by unknown causes.

    Brain Injury Or Trauma

    An injury or trauma to the skull and brain can lead to increased intracranial pressure. As mentioned, falls and car accidents are often responsible for this type of injury. Serious trauma that affects the brain can be life-threatening and requires emergency medical attention. Injury can lead to blood pooling and bleeding, which can cause permanent damage to brain tissues.

    Migraine Commonest Cause Of Pressure At Back Of The Head

    It is surprising to know that, 12% of the population in United States has been affected by migraine. Migraine is a medical condition in which individual suffers from pain on one side of the head. However, it may eventually spread to back of the head. Migraine usually causes severe headache, which may begin on one side of the head or can occur on top or back of head. While a person is suffering from a migraine attack, there may be symptoms like nausea, vomiting, throbbing pain in the head and even increased sensitivity to both light and sound. Other associated symptoms of migraine include colored or blind spots, flashing or sparkling of lights and weakness. These symptoms might last for around 5 to 30 minutes, while in some cases it can even last for hours.

    Black Americans And Cerebral Edema

    Certain racial and ethnic minorities are at a greater risk for some of the main causes of cerebral edema.

    According to a study published in 2018 in the Journal of Head Trauma Rehabilitation, the annual rate of emergency department visits for traumatic brain injuries is higher for Black Americans than for white Americans 569 per 100,000 compared with 457 per 100,000, respectively. Black Americans also have higher rates of hospitalization due to brain injury.

    The first sign of vision problems is loss of peripheral vision. People may not notice this loss at first. As a result, people may bump into objects for no apparent reason. Vision may be blurred briefly, sometimes triggered by changing position, and blurring may come and go. Late in the disorder, vision is blurred, and people may quickly become blind. As many as one third of people lose their vision, partially or completely, in one or both eyes. Once vision is lost, it usually does not return, even if the pressure around the brain is relieved.

    In some people, the disorder becomes chronic and progressively worse, increasing the risk of blindness. Doctors closely monitor and treat such people to prevent loss of vision.

    Idiopathic intracranial hypertension recurs in about 10 to 20% of people.

    Make Sure That Your Headaches Arent A Sign Of A Serious Illness

    Headaches can be a symptom of stress. Or they may be a sign of a serious physical problem. For example, a headache may be a symptom of a tumor in your brain, or of an infection of your brain or the coverings of your brain. Or of any number of serious health problems.

    This means that if you have chronic headaches, the first thing to do is to go see your doctor to make sure that your headaches arent being caused by a physical illness.

    You want to be sure to go see your doctor if you have a headache with any of the following qualities:

    • Your headache comes on abruptly and is severe
    • Your headache is accompanied by fever, a stiff neck, confusion, double vision or difficulty in speaking.
    • You have a headache after a head injury.

    Your doctor will take a history, do a physical examination and if necessary do blood tests and imaging studies.

    If your doctor doesnt find any physical cause for your tension headaches, then you can pretty much assume that they are probably caused by stress and/or anxiety. And then you can treat them accordingly.

    You can confirm for yourself that your tension headaches are probably caused by stress and/or anxiety if they have the following qualities:

    • Your headaches tend to occur during periods of feeling stressed/anxious.
    • Your headaches tend to occur along with other symptoms of stress or anxiety.
    • Your headaches tend to come and go depending on your level of anxiety/stress.

    What Are The Risk Factors For A Thunderclap Headache

    People with certain inherited conditions such as weak blood vessels or a tendency to develop blood clots have a higher risk of thunderclap headaches.

    Some people with high blood pressure may be more likely to experience thunderclap headaches. These people may be at higher risk of having a blood vessel rupture in the brain.

    For some people, activities such as heavy exertion and sexual activity can trigger thunderclap headaches. Once you identify these triggers, avoiding them can help reduce the number of headaches you experience. Your doctor can provide treatment options, including medications, to reduce your likelihood of repeated thunderclap headaches.

    How Is Brain Swelling Diagnosed

    The steps used by your doctor to diagnose brain swelling depend on the symptoms and the suspected cause. Common exams and tests used in the diagnosis include:

    • Head and neck exam
    • CT scan of the head to identify the extent and location of the swelling
    • MRI of the head to identify the extent and location of the swelling
    • Blood tests to check for causes of the swelling
    • Lumbar puncture

    What Does Pressure In The Back Of Your Head Indicate

    What is Intracranial Pressure?

    Whenever too much pressure is exerted on the brain, it can restrict the blood flow in brain leading to serious medical conditions. There are various factors which contribute to pressure in the back of your head including headaches, migraines, inflamed sinuses etc. Pressure in the head or headache is pain or discomfort experienced by people usually on head or neck. There are various causes of pressure in the back of your head, which further sends signals to the nerve cells of the brain. It is important to know what does pressure in the back of your head indicate.

    Do Brain Tumours Cause Headaches

    Headaches are one of the most common symptoms of a brain tumour, but they are also common in healthy people, and can be due to many everyday causes.

    The headaches are not caused directly by the tumour itself, as the brain has no pain receptors, but by a build-up of pressure on pain-sensitive blood vessels and nerves within the brain.

    The build-up of pressure can be due to the tumour pressing on these vessels/nerves or by the tumour blocking the flow of cerebrospinal fluid within the brain.

    Headaches are rarely the only symptom of a brain tumour.

    Doctors do NOT generally worry if your headache is:

    • occasional
    • mild
    • doesn’t last long
    • has an identifiable cause, such as a hangover, lack of sleep, flu-like illness, sinus infection or if you have been ‘fasting’ or overusing medication.

    However, people often worry whether their headache is due to something more serious, such as a brain tumour, particularly if they have frequent or severe headaches causing a lot of pain.

    If you’re worried, you should speak to your doctor, who can undertake a neurological examination. This involves testing your vision, hearing, balance, reflexes, arm and leg strength, and coordination. If this examination does not show anything outside the normal range and you have no other symptoms, you are unlikely to have a brain tumour.

    Getting Immediate Relief For Your Tension Headaches

    You can often feel a tension headache starting to build up in your head. You can feel the first signs of tension building up in the muscles of your head. When you sense that first sign of tension, slow down and stop whatever it is you are doing for a moment. Pay attention to the tension and accept it. This in and of itself may short circuit and stop the tension.

    Other things that might help stop the buildup of tension are:

    • Take a walk
    • Take a moment and slow down whatever it is you are doing.
    • Take some deep breaths to release your tension.
    • Massage the muscles in your head and neck to release the tension. This can be very effective.

    If none of these measures work, you might want to take an over the counter pain killer that you know and that works well for you. Experiment with your medication, and figure out the smallest does that will stop your headache effectively.

    But the most important thing to do is to take measure that will help you prevent the occurrence of tension headaches in the future.
