Head Injury

Any change in mental or physical functioning following a trauma to the head is referred to as a head injury (see the image below). In the United States, traumatic brain injuries cause more than 50,000 fatalities annually, according to the Centers for Disease Control and Prevention (CDC).

 Almost twice as many individuals have lasting impairments. TBI was a contributing factor in around 2.8 million emergency department (ED) visits, hospitalizations, or fatalities in the US in 2013—either on its own or in conjunction with other injuries.

Both closed and open head injuries are possible (penetrating).

A closed head injury occurs when you strike your head against something hard, yet the skull is not broken. 

When you sustain an open head injury, also known as a penetrating head injury, the skull is broken and the brain is struck. When moving quickly, such as when crashing through a windshield in an automobile collision, this is more likely to occur. Additionally, a gunshot to the head may cause it. 

These include head injuries, such as

The most common traumatic brain injury is a concussion, which occurs when the brain is shaken.

Hemorrhage may occur after a head injury:

The tissue of the brain 

A head injury is a frequent cause of emergency department visits because it can cause injuries to the brain's protective layers (subarachnoid haemorrhage, subdural hematoma, and epidural hematoma). Children make up a sizable portion of those who get brain injuries. Every year, more than 1 in 6 injury-related hospital admissions are due to traumatic brain injury (TBI).

Causes 

Typical reasons for head injuries include:

Accidents at work, home, outdoors, or at athletic events. 

A physical attack 

Traffic collisions 

Because the skull shields the brain, the majority of these wounds are small. Some injuries are serious enough to necessitate hospitalization.
