A doctor will make a small incision in the skull and insert a tube as a drain. This is a more invasive procedure that involves draining fluid from the brain. Though there’ve been some success stories with this method, controlled hypothermia is still being researched. Lowering the body temperature decreases metabolism in the brain and can also reduce swelling. HypothermiaĪnother treatment method includes inducing hypothermia. Controlling this process lowers the blood flow in your brain and reduces ICP. Proper blood flow in your brain is dependent upon carbon dioxide. Hyperventilation causes you to exhale more than you inhale, lowering the amount of carbon dioxide in your bloodstream. Some doctors may perform a controlled hyperventilation to help lower your ICP. This will help reduce swelling and ICP in the skull. Osmotic therapy also helps improve blood circulation. This is done using osmotic agents such as mannitol, or high-salt saline. Osmotherapy is a technique meant to draw water out of the brain. When your brain swells, it accumulates excess fluid. Medicationĭepending on the severity of your condition and the underlying cause, doctors may prescribe you medication to help reduce swelling and prevent blood clots. It’s also important to treat the underlying cause to prevent any further damage. Treatment options are meant to restore blood flow and oxygen to the brain while reducing the swelling. bites from poisonous animals, reptiles, and some marine animalsīrain swelling can become a life-threatening condition.Brain tumors can add pressure to areas of the brain, causing the surrounding brain to swell. Some bacteria can cause illnesses and disorders that lead to brain inflammation and swelling, especially if left untreated. This can cause brain cells to die and the brain to swell in response to the injury. An ischemic stroke occurs when there’s a blood clot near the brain, preventing the brain from receiving blood and oxygen. Some cases of stroke can cause brain swelling, specifically an ischemic stroke.

In more severe cases, a TBI can crack the skull and pieces of the skull can rupture blood vessels in the brain and cause swelling. Physical contact and falls can cause the brain to swell. There are several factors that can cause brain swelling.
