A penetrating head injury, or open head injury, is a head injury in which the dura mater, the outer layer of the meninges, is breached. [1] Penetrating injury can be caused by high-velocity projectiles or objects of lower velocity such as knives, or bone fragments from a skull fracture that are driven into the brain.
Mechanism-related classification divides TBI into closed and penetrating head injury. [10] A closed (also called nonpenetrating, or blunt) [14] injury occurs when the brain is not exposed. [15] A penetrating, or open, head injury occurs when an object pierces the skull and breaches the dura mater, the outermost membrane surrounding the brain. [15]
More than 50% of patients who suffer from a traumatic brain injury will develop psychiatric disturbances. [6] Although precise rates of anxiety after brain injury are unknown, a 30-year follow-up study of 60 patients found 8.3% of patients developed a panic disorder, 1.7% developed an anxiety disorder, and 8.3% developed a specific phobia.

The skull can be fractured, but not necessarily. A penetrating head injury occurs when an object pierces the skull and breaches the dura mater. Brain injuries may be diffuse, occurring over a wide area, or focal, located in a small, specific area. A head injury may cause skull fracture, which may or may not be associated with injury to the ...
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside ...
Post-traumatic epilepsy (PTE) is a form of acquired epilepsy that results from brain damage caused by physical trauma to the brain (traumatic brain injury, abbreviated TBI). [1] A person with PTE experiences repeated post-traumatic seizures (PTS, seizures that result from TBI) more than a week after the initial injury. [ 2 ]
An increase in pressure, most commonly due to head injury leading to intracranial hematoma or cerebral edema, can crush brain tissue, shift brain structures, contribute to hydrocephalus, cause brain herniation, and restrict blood supply to the brain. [13] It is a cause of reflex bradycardia. [14]
