Head injury
Head Injury
A Head Injury (pronunciation: /hɛd ˈɪndʒəri/) is a broad term that refers to any sort of physical harm to the head, brain, skull, or scalp. This can range from a minor bump or bruise to a traumatic brain injury.
Etymology
The term "Head Injury" is derived from the Old English words "heafod" meaning head, and "injurie" from Latin "injuria" meaning wrong or damage.
Types of Head Injuries
Head injuries can be classified into two main categories:
- Closed Head Injury: This occurs when the head sustains a blunt force by striking against something. The skull does not break or fracture in this type of injury, but it can still cause damage to the brain.
- Open (Penetrating) Head Injury: This is when an object penetrates the skull and enters the brain. This is a very serious type of injury and can lead to permanent damage or death.
Symptoms
Symptoms of a head injury can vary greatly depending on the severity and type of injury. They may include:
- Headache
- Loss of consciousness
- Confusion
- Dizziness
- Nausea or vomiting
- Memory loss (amnesia)
- Mood changes
Treatment
Treatment for head injuries depends on both the type and the severity of the injury. It can range from rest and over-the-counter medication to surgery and physical therapy. It is crucial to seek medical attention if a head injury is suspected.
