Brain swelling or known as cerebral edema is a condition where there is a buildup of fluid in brain tissue. Swelling of the brain is not a trivial matter, so the cause must be immediately found and treated
The brain is very susceptible to damage if there is edema or swelling because it is located in a closed cranial cavity. So when the size increases, the brain will be pressed against the skull. The brain can swell due to certain injuries or diseases, such as infections, tumors or strokes.
Various Causes of Brain Swelling
Swelling of the brain can occur in certain parts of the brain or in all parts of the brain depending on the underlying cause. Some of the causes of brain swelling that you need to recognize are:
Viral, bacterial and parasitic infections in the brain can cause brain swelling. This can occur in meningitis, brain abscess, encephalitis, and toxoplasmosis.
Swelling of the brain can also occur due to traumatic brain injury or brain damage due to head injury. This condition can be caused by several events, such as a traffic accident, being hit, or hitting the head with an object.
3. Ischemic stroke
Ischemic stroke is the most common type of stroke that causes the brain to swell.The emergence of ischemic stroke is caused by blockage of blood vessels in the brain. This results in the brain not getting a supply of oxygenated blood. As a result, brain cells begin to die and swelling ensues.
4. Brain hemorrhage
The appearance of blood that irritates brain tissue can also cause brain swelling. This brain hemorrhage can be caused by many factors, ranging from injury, hemorrhagic stroke or stroke caused by a ruptured blood vessel, to the rupture of a brain aneurysm.
Tumors growing in the brain can cause brain swelling in a number of ways. As it progresses, the tumor can press on other parts of the brain and may also block cerebrospinal fluid from flowing out of the brain, causing swelling.
This condition is caused by a buildup of fluid in the brain, resulting in swelling. Hydrocephalus can occur due to a blockage in the flow of cerebrospinal fluid, impaired absorption of cerebrospinal fluid, or due to excessive production of cerebrospinal fluid.
7. High Altitude Cerebral Edema (HACE)
HACE is a fatal condition that occurs when someone climbs a mountain or is at an altitude of 2500−4000 meters. Symptoms can include impaired coordination of body movements, headaches, fatigue, and decreased consciousness. This condition is the most severe form of altitude sickness.
Symptoms Caused by Swelling of the Brain
The symptoms of edema or swelling of the brain vary depending on the severity and cause. Usually brain swelling causes symptoms, such as:
- Stiffness or pain in the neck
- irregular breathing
- Lost memory
- Loss of consciousness
- Sight becomes blurry
- Inability to walk
One of the most dangerous complications due to brain swelling is brain herniation. This condition occurs when brain tissue bulges out of its normal position in the head cavity.
As a preventative measure from brain swelling, there are several things that need to be done, namely always wearing a helmet when exercising, skating, or riding a motorbike; wear seat belts properly when driving; and live a he althy lifestyle to prevent high blood pressure and stroke.
Swelling of the brain is a condition to watch out for. You will be more at risk for this if you have risk factors for stroke, such as high blood pressure, high cholesterol, have risk factors for brain infections, such as decreased immunity, or have a history of tumors.
If you experience symptoms of brain swelling and indeed have risk factors for this condition, immediately consult a neurologist to get an examination and treatment as early as possible.
