  • Brain trauma
  • Stroke

According to Live Strong , brain swelling can be caused by parasitic, bacterial, and viral infection in the casing around the brain. The casing is known as meninges.

The most common cause of infection is bacteria. When a child has a severe case of chicken pox, the bacteria can spread to the brain.

Meningitis is when this casing becomes infected. It can be a serious and life threatening condition. It is one of the rare complications of chicken pox.

Can An Allergic Reaction Cause Brain Swelling

Since these organs cannot function properly, the body goes into shock. In addition, the body responds to the allergen by releasing chemicals such as histamines that cause swelling of the skin, a red rash, and severe itching. Complications of anaphylactic shock can include brain damage, kidney failure, and/or death.

Encephalitis Causes And Types

Encephalitis can be caused by infections or autoimmune conditions where the bodys own immune responses attack the brain. Even with extensive testing, the specific cause of encephalitis remains unknown in about 30%40% of cases.

Cases of encephalitis are likely to continue to rise as more and more autoimmune causes are recognized. Emerging infections such as Zika, chikungunya and Powassan viruses can also contribute to this trend.

Examples Of Ketogenic Foods That Can Help Reduce Brain Inflammation Include:

  • Avocados
  • Salmon and other fatty fish
  • Almonds and other tree nuts
  • MCT oil, which is found in high levels in the coconut
  • Olive oil

The ketogenic diet can also help to decrease blood sugar, which can increase brain inflammation when it is too high. High blood sugar releases pro-inflammatory stress hormones and can impede tissue regeneration or repair in the brain.

Types Of Brain Injury


Types of brain injuries can broadly be classified as Traumatic Brain Injury or Acquired Brain Injury .

Traumatic Brain Injury: Sudden traumatic experiences such as accidents, blow to the head and gunshot wounds that cause forceful impact to the brain and subsequent brain damage are collectively referred to as traumatic brain injury. The trauma resulting from such an incident can cause swelling of the brain, nerve tears, brain stem injury and affect brain function. Traumatic brain injury can result from closed head wounds as well, and manifest through various symptoms in degrees of severity. A mild concussion will require only rest and over the counter medication

however, a more severe brain injury symptom may be identified only a little later, after some time has passed. It is therefore very necessary to monitor symptoms of brain injury for 48-72 hours after an incident.

Acquired brain injury: An acquired brain injury results from events after birth and are not congenital in nature. They can result from trauma, or from substance abuse or tumours that disrupt blood and oxygen flow to the brain. Paediatric acquired brain injury can affect the mental and emotional well being of children and would need attention from psychologists, in addition to medical treatment from a neurologist.

Causes Of A Brain Abscess

There are 3 main ways a brain abscess can develop. These are:

  • an infection in another part of the skull such as an ear infection, sinusitis or dental abscess, which can spread directly into the brain
  • an infection in another part of the body for example, the infection that causes pneumonia spreading into the brain via the blood
  • trauma, such as a severe head injury that cracks open the skull, allowing bacteria or fungi to enter the brain

However, in some cases, the source of the infection remains unknown.

What You Need To Know

  • Symptoms of encephalitis vary depending on the affected area of the brain, but often include headache, sensitivity to light, stiff neck, mental confusion and seizures.
  • Its important to see a doctor promptly if you are experiencing symptoms, which may not seem troubling at the time. Timely diagnosis and treatment are the keys to a successful recovery from encephalitis.
  • There are many types of encephalitis, and the causes vary from a viral infection to an abnormal response of the immune system.

You Experience Brain Fog

Deadly mosquito-borne virus that causes brain swelling found in Florida

If we are talking about chronic inflammation due to lifestyle and/or toxins, brain fog and slowed cognitive skills may be some signs to look out for. When you have brain fog, you might lose your train of thought easily and you’ll have trouble focusing on your everyday tasks. As Carolyn Dean, MD, ND, author of 365 Ways to Boost Your Brain Power: Tips, Exercise, Advice, tells Bustle, limiting dairy consumption, sugary foods, smoking, and alcohol may help with these symptoms.

Cerebral Edema Signs And Symptoms

Cerebral edema can be asymptomatic, merely seen on imaging, or it can cause life-threatening complications. The history can help provide insights as to the etiology of the cerebral edema. Patients may have a history of trauma, a hypoxic event, cancer, metabolic diseases or other factors which can help identify the possible etiology of the cerebral edema.

The physical exam findings of cerebral edema can vary widely depending on the location and extent of the cerebral edema. Localized cerebral edema can cause dysfunction of the edematous brain and include weakness, visual disturbances, seizures, sensory changes, diplopia, and other neurologic disturbances. For diffuse cerebral edema, the patient may have headaches, nausea, vomiting, lethargy, altered mental status, confusion, coma, seizure or other manifestations. With diffuse or focal cerebral edema the patient can develop increased intracranial pressure which typically presents with headaches, nausea, vomiting, lethargy, cranial neuropathy, altered mental status to coma and death.

What Treatments Are Available

Mild TBI usually requires rest and medication to relieve headache. Moderate to severe TBI require intensive care in a hospital. Bleeding and swelling in the brain can become an emergency that requires surgery. However, there are times when a patient does not require surgery and can be safely monitored by nurses and physicians in the neuroscience intensive care unit .

The goals of treatment are to resuscitate and support the critically ill patient, minimize secondary brain injury and complications, and facilitate the patient’s transition to a recovery environment. Despite significant research, doctors only have measures to control brain swelling, but do not have a way to eliminate swelling from occurring.

Neurocritical care Neurocritical care is the intensive care of patients who have suffered a life-threatening brain injury. Many patients with severe TBI are comatose or paralyzed they also may have suffered injuries in other parts of the body. Their care is overseen by a neurointensivist, a specialty-trained physician who coordinates the patient’s complex neurological and medical care. Patients are monitored and awakened every hour for nursing assessments of their mental status or brain function.

Warning Signs Of A Serious Brain Injury

  • Pain: Constant or recurring headache
  • Motor dysfunction: Inability to control or coordinate motor functions or disturbance to balance
  • Sensory: Changes in ability to hear, taste or see dizziness hypersensitivity to light or sound
  • Cognitive: Shortened attention span easily distracted overstimulated by environment difficulty staying focused on a task, following directions or understanding information feeling of disorientation, confusion and other neuropsychological deficiencies
  • Speech: Difficulty finding the “right” word difficulty expressing words or thoughts dysarthric speech

Seek immediate medical attention if any of these warning signs occur

Modes Of Transmission Of Viruses

Cerebral edema or brain swelling causes, symptoms ...

Viruses spread by different means, and some are more infectious than others. Some of the modes of viral transmission include:

  • coughs or sneezes from an infected person that release airborne viruses, which are then inhaled by others
  • infected insects and animals, which can transfer some viruses directly into the bloodstream via their bite
  • eating contaminated food or drink
  • the transfer of some viruses can occur through touching an infected person
  • there is evidence to suggest that some cases of viral encephalitis are caused by a dormant viral infection becoming active again.

A Ketogenic Diet Of Anti

Foods associated with a ketogenic diet

During brain swelling, the glucose uptake that surges to the injured area to provide energy for healing and repair is eventually blocked. The only other viable energy source in that case are ketone bodies, which can be delivered to the brain through fatty acid oxidation in the liver.

The ketogenic diet, which is high in fat, low in carbohydrates, and adequate in protein, has recently proven to reduce brain inflammation in rats and it is an established treatment for epilepsy in children.

Swelling Of The Brain Types And Causes

Posted by Dr. Chris

There are three parts to the brain the cerebrum which is the largest part, the cerebellum and the brainstem. Any organ of the body may become swollen and the brain can also swell for various reasons. This can increase pressure on and in the brain and even affect its functioning. With the brain being a vital organ, this swelling can be serious and even life threatening.

Identification Of High Risk Patients

Vigilant recognition of high risk patient populations likely to develop brain swelling serve as a cornerstone of the modern approach to brain swelling in the Neuro ICU. Early recognition of impending brain swelling can guide the frequency of neurological examinations, initiation of medical and surgical therapies, and communication with family members about the anticipated clinical course. Patients at high risk of developing brain swelling should be promptly considered for transfer to a center with multidisciplinary expertise in neurocritical care and neurosurgery. and shows the risk factors for developing brain swelling following ischemic stroke and ICH, respectively. Thrombolysis risk using the modified Rankin Scale and NIH Stroke Scale score is a tool described recently that can predict the development of cerebral edema within 24 hours after ischemic stroke with good sensitivity and specificity.

Can Encephalitis Be Prevented

You Experience Nausea Or Vomiting

Encephalitis can give you feelings of nausea, Dr. Dean says. The usual cause of this type of brain inflammation is a viral infection like the herpes simplex virus. In fact, brain inflammation due to herpes makes up 10 percent of all cases of encephalitis in the United States per year. Other symptoms include a stiff neck, drowsiness, and general weakness, so speak to your doctor if you notice any of these ailments.

. Herein, can brain swelling kill you?

Your brain can also swell as a result of injury, illness, or other reasons. Brain swelling, though, can quickly cause serious problems — including death. It’s also usually more difficult to treat. As your body’s master control system, the brain is critical to overall function.

Likewise, can stress cause brain swelling? Now researchers have performed a new study in mice that they believe reveals another effect of chronic stress on the brain: Inflammation, which can lead to memory loss and depression. The stress, it seemed, was causing the mice’s immune systems to attack their own brains, causing inflammation.

Likewise, how do you treat brain swelling?


  • Medication: Doctors will use drugs to reduce swelling or blood clots.
  • Surgery: In severe cases, surgery may be necessary to reduce ICP.
  • Hypothermia: This form of therapy involves lowering the body temperature, which can reduce swelling in the brain.
  • How dangerous is swelling of the brain?

    Cerebral edema is also known as brain swelling. It’s a life-threatening condition that causes fluid to develop in the brain. This fluid increases the pressure inside of the skull more commonly referred to as intracranial pressure . Left untreated, cerebral edema can be fatal.

    Swelling In The Brain

    Brain swelling goes by a variety of names brain edema, cerebral edema, elevated intracranial pressure but they all involve an increase in pressure inside your skull. Swelling is part of the normal healing process, but if it causes excess pressure or bleeding, serious problems can occur.

    Swelling can set in for a number of reasons, the most common being acute trauma. Clashing heads with an opponent during a soccer match or slipping on the ice and striking your head on the frozen ground can both result in cranial swelling. Aside from a traumatic brain injury, some reasons brain swelling may occur include:

    • Blood clot/stroke
    • Infections, like meningitis, encephalitis or a subdural empyema
    • Tumors

    Infections Poisoning And Toxins

    Cerebral Edema: Causes, Symptoms, and Treatment

    Various infections may arise in the brain and surrounding tissue with inflammation resulting in edema. This may be due to bacteria, viruses, parasites or rarely even fungi seen in immunocompromised patients like with HIV/AIDS and diabetics . Apart from edema of the brain tissue or meninges , a collection of pus associated with an infection and filling of cavities with pus may also cause swelling and compression of the brain tissue.

    What Are The Causes Of Brain Swelling Symptoms & Treatment

    Brain swelling, also known as cerebral edema in medical terminology is a serious neurological condition. Swelling can occur in any organ of the body. It is bodys response to any type of injury, infection or an overuse of that particular organ or part of the body. Brain edema can develop as a result of an injury to brain or infection in the brain. It may involve certain part of brain or the whole brain.

    Brain swelling produces increase in intracranial pressure. Intracranial pressure prevents proper blood flow to the brain as a result the brain cells are deprived of vital food that is oxygen and glucose.

    Types Of Traumatic Brain Injury

    Traumatic brain injuries may be focal, in a small specific area, or diffuse injury over a large area of the brain, which may not be apparent on a CT scan, but causes TBI symptoms.

    Types of traumatic brain injuries include the following:

    • Hematoma: A hematoma is a blood clot that forms inside or on the surface of the brain after an injury.
    • Contusion: Contusions are areas of bruising, with injured brain tissue and blood that has leaked out of tiny blood vessels.
    • Hemorrhage: Hemorrhage is uncontrolled bleeding in any part of the brain, which may be of two types:
    • Subarachnoid hemorrhage: Bleeding in the space around the brain.
    • Intracerebral hemorrhage: Bleeding within the brain tissue.
    • Diffuse axonal injury: Axons are long, hair-like projections from nerve cells , which enable communication between nerve cells and make the body function. Diffuse axonal injury is one of the most dangerous types of TBI because it can cause severe and lasting disabilities.
    • Ischemia: Ischemia is inadequate blood supply to parts of the brain, because of injury.
    • Skull fractures: Skull fractures may be simple cracks in the skull or fragments of skull that push into the brain, damage brain tissue, blood vessels and nerves, and cause leakage of the cerebrospinal fluid.

    High Altitude Sickness Treatment

    Early diagnosis is important. Acute mountain sickness is easier to treat in the early stages.

    The main treatment for all forms of mountain sickness is to climb down to a lower altitude as rapidly and safely as possible. You should not continue climbing if you develop symptoms.

    Extra oxygen should be given, if available.

    People with severe mountain sickness may need to be admitted to a hospital.

    A medicine called acetazolamide may be given to help you breathe better. It can help reduce symptoms. This medicine can make you urinate more often. Make sure you drink plenty of fluids and avoid alcohol when taking this drug. This medicine works best when taken before reaching a high altitude.

    If you have fluid in your lungs , treatment may include:

    • Oxygen
    • A high blood pressure medicine called nifedipine
    • Beta agonist inhalers to open the airways
    • Breathing machine in severe cases
    • Medicine to increase blood flow to the lungs called phosphodiesterase inhibitor

    Dexamethasone may help reduce acute mountain sickness symptoms and swelling in the brain .

    Portable hyperbaric chambers allow hikers to simulate conditions at lower altitudes without actually moving from their location on the mountain. These devices are very helpful if bad weather or other factors make climbing down the mountain impossible.

    What Is Cerebral Edema

    Encephalitis (âBrain Inflammationâ?) Signs and Symptoms (& Why They Occur)

    Cerebral edema is the medical term for swelling of the brain. Cerebral refers to the brain and edema means swelling. It occurs when the brain tissue swells due to an increase of fluid in the tissue spaces or within the cell itself. This leads to raised intracranial pressure as the brain enlarges to occupy more space than is available within the cranial cavity .

    The pressure on the brain can cause a wide range of symptoms but initially and with moderate swelling, there may be no clear symptoms.This is also dependent on whether only certain parts of the brain are swollen or if the swelling is throughout the brain. It can be serious and depending on the underlying cause, even life threatening.
