Closed head injury
Closed Head Injury
A Closed Head Injury (pronunciation: /ˈkləʊzd hɛd ˈɪndʒəri/) is a type of Traumatic Brain Injury that occurs when a sudden, violent motion or impact causes the brain to knock against the skull. Unlike an open head injury, the skull is not broken or penetrated in a closed head injury.
Etymology
The term "Closed Head Injury" is derived from the fact that the injury occurs within the confines of the skull, which remains closed or unbroken. The term "head injury" is from the Old English "heafod" meaning "top of the body," and the Latin "injuria" meaning "a wrong."
Symptoms
Symptoms of a Closed Head Injury can vary widely depending on the severity of the injury. They may include Headache, Dizziness, Nausea, Vomiting, Confusion, Memory loss, and changes in mood or behavior. In severe cases, symptoms may also include Loss of consciousness, Seizures, and Coma.
Diagnosis
Diagnosis of a Closed Head Injury typically involves a physical examination and imaging tests such as a Computed Tomography (CT) scan or Magnetic Resonance Imaging (MRI). The Glasgow Coma Scale may also be used to assess the severity of the injury.
Treatment
Treatment for a Closed Head Injury can range from rest and over-the-counter pain relievers for mild injuries, to surgery and intensive care for severe injuries. Rehabilitation therapies such as Physical therapy, Occupational therapy, and Speech therapy may also be needed to help the patient recover.
