Numbness or paralysis in any part of the body. A questionnaire has been developed to assist with classification. These are usually summed to produce a total score. The Abbreviated Injury Scale (AIS) is an anatomical-based coding system created by the Association for the Advancement of Automotive Medicine to classify and describe the severity of injuries. It represents the threat to life associated with the injury rather than the comprehensive assessment of the severity of the injury. The Glasgow Coma Scale (GCS), the most commonly used system for classifying TBI severity, grades a person's level of consciousness on a scale of 3–15 based on verbal, motor, and eye-opening reactions to stimuli.

The most common symptoms are drowsiness, inattentiveness or confusion, headaches, changes in personality, seizures and mild paralysis. These injuries can result in long-term complications or death. However, patients with moderate TBI particularly in association with agitation invariably also benefit from sedation and ventilation prior to a CT scan. Severe TBI (i.e. It happens when the brain rapidly shifts inside the skull as an injury is occurring. Available for Android and iOS devices. This is an example of classification of TBI severity during the acute phase of injury. does the patient need intensive in-patient rehabilitation or can they be better managed by a rehabilitation team in the community. Potential brain injury may exist if the patient had any of the following: The Mayo system is a useful classification system in the community rehabilitation setting, and has been used by the Hertfordshire Acquired Brain Injury Team. A severe head injury can be fatal, or can require an extended hospital stay with prolonged rehabilitation. In some cases, the skull is dented inward so that fragments of shattered bone are pressed against the surface of the brain. Of critical importance is not to regard GCS as a static measure; repeating it by the process of regular (usually 30 minute observations) is a fundamental part of the management of patients with TBI. A chronic subdural hematoma typically follows a fairly minor head injury in a person who is elderly, who is taking blood-thinning medications or whose brain has shrunk as a result of alcoholism or dementia.

Multiple criteria are used in each diagnosis including loss of consciousness, post-traumatic amnesia, skull fracture, and evidence of neuroradiological abnormalities including subdural haematoma, cerebral contusion, and hemorrhagic contusion. Both their cars spun wildly out of control and crashed. (Ed) Manual of Traumatic Brain Injury Management. In 24 of these cases the diagnosis could not have been made without microscopical examination, while in a further 31 microscopical examination was … Head trauma can cause swelling inside the brain and a potentially deadly increase in pressure inside the skull.

Classification of TBI is important in terms of differentiating a MTBI from a moderate-severe TBI given the difference in cognitive outcome15. AIS is one of the most common anatomic scales for traumatic injuries. Classification can help the clinician to predict outcomes in the longer term which may help to guide treatment decisions in the post-acute stages i.e. This prognostic classification system is a development on Russell and Smith’s classification system where a PTA of 1-7 days was viewed as severe, and a PTA of 7+ days was viewed as very severe4. Some doctors classify head injuries into three categories, based on symptoms: All head injuries should be evaluated promptly by a doctor, so either call for emergency help or have a friend or family member drive you to an emergency department.

There are different systems for classifying traumatic brain injury (TBI). TBI can be classified by pathoanatomic type i.e. It occurs when a sudden trauma damages the brain and disrupts normal brain function. A concussion is a traumatic brain injury that affects your brain function. If the results of these exams are normal, you may not need further tests. This could help clinicians provide family members with a more accurate prognosis. A concussion usually improves within three months. There is a risk that this may then become a case of ‘expectation as aetiology’. Symptoms of a concussion can include not having memory of the minutes immediately before the injury, temporarily losing consciousness, or having vomiting, dizziness, coordination problems, confusion, ringing in the ears, sleepiness or seizures.

Grade 2 – Characterized by headaches that are often migraine-like in character, with associated symptoms. The Mayo system is structured in a conservative way to reflect severity of brain trauma based on the strength of available evidence i.e. A grade 3 or 4 concussion will mean at least a few weeks of recovery time. There is a general trend now to classify a MTBI as an injury in which the individual is not unconscious for more than thirty minutes, post-traumatic amnesia does not extend beyond 24 hours, and there are no abnormalities on neuroimaging5,6,7,15.
