The relative risk of post-traumatic seizures (PTS) increases with the severity of traumatic brain injury (TBI). [128] A CT of the head years after a traumatic brain injury showing an empty space where the damage occurred marked by the arrow. Improvement of neurological function usually occurs for two or more years after the trauma.
A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [9] Symptoms may include loss of consciousness; memory loss; headaches; difficulty with thinking, concentration, or balance; nausea; blurred vision; dizziness; sleep disturbances, and mood changes.

Glasgow Coma Scale (GCS) is the most widely used scoring system used to assess the level of severity of a brain injury. This method is based on the objective observations of specific traits to determine the severity of a brain injury. It is based on three traits: eye opening, verbal response, and motor response, gauged as described below. [35]
Prognosis, or the likely progress of a disorder, depends on the nature, location, and cause of the brain damage (see Traumatic brain injury, Focal and diffuse brain injury, Primary and secondary brain injury). In children with uncomplicated minor head injuries the risk of intracranial bleeding over the next year is rare at 2 cases per 1 million ...
In traumatic brain injury (TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain. [1] Secondary brain injury occurs gradually and may involve an array of cellular processes. [1] [2] Secondary injury, which is not caused by mechanical damage, can result from the primary ...
The Glasgow Coma Scale is commonly used to assess the severity of traumatic brain injuries, including closed-head injuries. The scale tests a patient's eye, verbal, and motor responses. The scale goes up to fifteen points; with fifteen being the most mild injury, less than eight being a severe brain injury, and three being a vegetative state. [12]
Concussion, a type of mild traumatic brain injury that is caused by a direct or indirect hit to the head, body, or face is a common injury associated with sports and can affect people of all ages. A concussion is defined as a "complex pathophysiological process affecting the brain, induced by biomechanical forces". [ 1 ]
A cerebral laceration is a type of traumatic brain injury that occurs when the tissue of the brain is mechanically cut or torn. [1] The injury is similar to a cerebral contusion; however, according to their respective definitions, the pia-arachnoid membranes are torn over the site of injury in laceration and are not torn in contusion.
