A closed head injury is when an object hits and hurts the head but doesn’t go through the skull. Even though the object doesn’t go through the skull, parts of the head can still get damaged. The most common causes of a closed head injury are falls, sports injuries, and car and bike accidents. These types of injuries can cause other problems like bleeding in or around the brain and brain swelling, also known as a concussion.
A closed brain injury is damage to the brain caused by a forceful blow, jolt, or bump to the head that does not involve an object penetrating the skull. This kind of traumatic brain injury can be limited to one part of the brain or can affect the whole brain. Depending on the level of damage sustained by the brain, closed brain injuries can have mild symptoms, such as a headache, or more severe symptoms, such as seizures. A mild closed brain injury is also known as a concussion. Many cases of closed brain injury are relatively mild, but closed brain injuries can be serious and even fatal.
