Mild Brain Injury Symptoms

The most common type of mild head injury is concussion. It happens when the brain receives trauma from an impact or a sudden movement change.

Severe Brain Injury Symptoms

According to the Brain injury Association of America, severe brain injury may cause the person to experience deep sleep where one cannot be aroused nor can he respond purposefully. He has no sleep or wake cycles resulting in a coma or longer period of unconsciousness.

Glasgow Coma Scale

The Glasgow Coma Scale is a neurological scale designed to assess the patient’s level of consciousness after brain injury. The scale evaluates the patient’s best eye response, best verbal response, and best motor response, and then assigns a score that ranges from 3 to 15.
