A head injury is any injury that results in trauma to the skull or brain. The terms traumatic brain injury and head injury are often used interchangeably in the medical literature. [ 1 ] Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that ...
A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
Closed-head injuries are caused primarily by vehicular accidents, falls, acts of violence, and sports injuries. [4] Falls account for 35.2% of brain injuries in the United States, with rates highest for children ages 0–4 years and adults ages 75 years and older. [3] Head injuries are more common in men than women across every age group. [3]
Chronic subdural bleeds develop over a period of days to weeks, often after minor head trauma, though a cause is not identifiable in 50% of patients. [11] They may not be discovered until they present clinically months or years after a head injury. [25] The bleeding from a chronic hematoma is slow and usually stops by itself.
Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries. [3]
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
