Some conditions share characteristics with coma and must be ruled out in a differential diagnosis before coma is conclusively diagnosed.

For instance, coma induced by a diffuse metabolic process, such as hypoglycemia, can result in a structural coma if it is not resolved. It is based on three traits eye opening, verbal response, and motor response, gauged as described below.

The difference between coma and stuporis that a patient with coma cannot give a suitable response to either noxious or verbal stimuli, whereas a patient in a stupor can give a crude response, such as screaming, to an unpleasant stimulus.

Severe traumatic brain injury (TBI) often results in coma and subsequent disorders of consciousness such as unresponsive wakefulness syndrome (UWS) (former vegetative state)1, 2, 3or minimally conscious state (MCS).4The survival rate after a TBI, severe enough to cause deep coma and low Glasgow Coma Scale (GCS) scores, is generally poor, even in young adults. After this time, some patients gradually come out of the coma, some progress to a Predicted chances of recovery will differ depending on which techniques were used to measure the patient's severity of neurological damage. GCS was used to assess a person's level of consciousness after a head injury, and the …

The Coma Recovery Scale (CRS-R), also known as the JFK Coma Recovery Scale - revised, is used to assess patients with a disorder of consciousness, commonly coma. There are five grades starting with the most severe:

The method, called Research by Dr. Eelco Wijdicks on the depiction of comas in movies was published in Neurology in May 2006.

Glasgow Coma Scale (GCS) is the most widely used scoring system used to assess the level of severity of a brain injury.

It was designed by doctors Terrie Taylor and Malcolm Molyneux in 1987, and named for the Malawian city of Blantyre, site of the Blantyre Malaria Project. for high-level cognitive activities: it requires being able to distinguish something, track it for a while, recognize it over time, and have certain emotional dispositions The Blantyre Coma Scale is a modification of the Pediatric Glasgow Coma Scale, designed to assess malarial coma in children. A structural cause, for example, is brought upon by a mechanical force that brings about cellular damage, such as physical pressure or a blockage in neural transmission. when there is suspicion of an aneurysm, carotid sinus fistula, traumatic vascular occlusion, and vascular dissection. This method is based on the objective observations of specific traits to determine the severity of a brain injury. It was decided that several things required updating, like the Eye Response element, meaning that instead of responding to "Painful Stimuli" being regarded as a 2, a person that opens their eyes in response to pressure is now considered a 2 in the Eye Response element.Note that a motor response in any limb is acceptable.There are four grades starting with the most severe:

It can also be used to monitor emergence from minimally conscious state (EMCS or MCS+).

Excellent concurrent validity with original Coma Recovery Scale (Spearman rho = .97) and Disability Rating Scale (Spearman rho=-.90) Use of CRS-R scores to diagnose vegetative state, minimally conscious state or minimally conscious plus state had adequate correlation between two raters (k=.60, p=.03), and better correlation for a single rater on two occasions (k=.82, p<.004). C'est un diagnostic le plus souvent évident en fonction du contexte : accident de la voie publique, agression, chute, etc.

Individual elements as well as the sum of the score are important.

Pupil assessment is often a critical portion of a comatose examination, as it can give information as to the cause of the coma; the following table is a technical, medical guideline for common pupil findings and their possible interpretations:Treatment for people in a coma will depend on the severity and cause of the comatose state. Moving patients every 2–3 hours by turning them side to side is crucial to avoiding Pneumonia is also common in coma patients due to their inability to swallow which can then lead to Coma patients may also deal with restless, or seizures. There are two main subdivisions of a coma: structural and diffuse neuronal. Clinically, a coma can be defined as the inability to consistently follow a one-step command.General symptoms of a person in a comatose state are: It may be used to differentiate between vegetative state (VS) and minimally conscious state (MCS). COMA RECOVERY SCALE-REVISED ©2004 Administration and Scoring Guidelines Joseph T. Giacino, Ph.D. and Kathleen Kalmar, Ph.D. Center for Head Injuries Edison, New Jersey Johnson Rehabilitation Institution Affiliated with JFK Medical Center Updated 11-1-05 . The GCS has limited applicability to children, especially below the age of 36 months (where the verbal performance of even a healthy child would be expected to be poor).

As such, after gaining stabilization of the patient's airways, breathing and circulation (the basic When an unconscious person enters a hospital, the hospital utilizes a series of diagnostic steps to identify the cause of In the initial assessment of coma, it is common to gauge the In those with deep unconsciousness, there is a risk of In the treatment of traumatic brain injury (TBI), there are 4 examination methods that have proved useful: skull x-ray, angiography, computed tomography (CT), and magnetic resonance imaging (MRI).

A deeper coma alone does not necessarily mean a slimmer chance of recovery, similarly, milder comas do not ensure higher chances of recovery . The most common cause of death for a person in a vegetative state is secondary People may emerge from a coma with a combination of physical, intellectual, and psychological difficulties that need special attention. Some psychiatric diseases appear similar to coma.
