What is the coma recovery scale for pediatrics (CRS-P)?
The pediatric version of the CRS-R, the Coma Recovery Scale for Pediatrics (CRS-P) should be used when assessing children between the ages of one and five who have not yet completed language and motor development (Slomine 2019). In a review of scales that assess DoC, CRS-R was the only scale recommended with minor reservations.
What is the Glasgow Coma Scale?
Glasgow Coma Scale The Glasgow Coma Scale (GCS) is a point scale used to assess a patient's level of consciousness and neurological functioning after brain injury. The scoring is based on best eye-opening response (1 - 4 points), best motor response (1 - 6 Points) and best verbal response (1 - 5 Points) with cut the off-point for coma at 8 points.

What GCS score is good prognosis for recovery?
GCS scores range from 3 to 15, with a lower score indicating more severe damage and a poorer prognosis. The GOS is a commonly used scale to assess the outcome in traumatic brain injury patients. This scale ranks the outcome from 1 (dead) to 5 (good recovery)[26].
What is the Four Score neurological assessment?
The FOUR Score is a 17-point scale (with potential scores ranging from 0 - 16). Decreasing FOUR Score is associated with worsening level of consciousness. The FOUR Score assesses four domains of neurological function: eye responses, motor responses, brainstem reflexes, and breathing pattern.
How long is recovery after a coma?
Comatose patients either improve to regain their consciousness within the first 2 to 4 weeks or they are diagnosed with vegetative state, chronic coma and minimal state of consciousness [2]. Most brain injuries do not lead to death and the patients survive for a prolonged period.
Can the Glasgow Coma Scale predict recovery?
Gait and Glasgow Coma Scale scores can predict functional recovery in patients with traumatic brain injury. Neural Regen Res.
What does a Glasgow score of 3 mean?
Patients with head injury with low Glasgow Coma Scale (GCS) scores on hospital admission have a poor prognosis. A GCS score of 3 is the lowest possible score and is associated with an extremely high mortality rate, with some researchers suggesting that there is no chance of survival.
What does 4 scores mean?
Lincoln's Gettysburg Address begins with the words, “Four score and seven years ago our fathers brought forth, upon this continent, a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal.” A score is another way of saying 20, so Lincoln was referring to 1776, which was 87 ...
What does GCS 4 mean?
The levels of response in the components of the Glasgow Coma Scale are 'scored' from 1, for no response, up to normal values of 4 (Eye-opening response) 5 ( Verbal response) and 6 (Motor response) The total Coma Score thus has values between three and 15, three being the worst and 15 being the highest.
What is the normal GCS score?
The responses are scored between 1 and 5 with a combined total score of 3 to 15, with 15 being normal. An initial score of less than 5 is associated with an 80% chance of being in a lasting vegetative state or death. An initial score of greater than 11 is associated with 90% chance of recovery.
What is a Stage 4 coma?
Stage 4 – Higher Level of Responsiveness A patient at this stage may not be fully aware of their limitations. Family and friends might notice some personality changes at this stage as well. The recovery process is different for everyone, and some patients could stay in one stage longer than the other.
Do you age while in a coma?
the cellular mechanism for ageing has been associated with progressive shortening of telomere length on the ends of each chromosome with each cell cycle.. in the contect of this, a coma wouldnt necessarily keep you young, but you would age just the same.
How long does brain damage take to heal?
A plethora of complications from traumatic brain injuries, ranging from minor cognitive delays to debilitating and life threatening symptoms such as seizures and coma, can follow the victim for years after the injury. You need to know that brain injury recovery time can take anywhere from a few weeks to ten years.
Can a person survive with GCS of 3?
Although the presence of fixed, dilated pupils in association with a GCS score of 3 has led to a 100% mortality rate in a number of studies,9,13 our findings show that survival and even good outcome (although very rare) are still possible.
Can you survive with a GCS 6?
Based on the results of present study, the survival rate of patients with very severe head trauma (GCS < 6) was 41.7%. The strong predictors of survival and 6-month favorable outcome of these patients were brisk pupillary reactivity and patent cistern on brain CT scan.
What does GCS 3 mean in medical terms?
The GCS is the summation of scores for eye, verbal, and motor responses. The minimum score is a 3 which indicates deep coma or a brain-dead state. The maximum is 15 which indicates a fully awake patient (the original maximum was 14, but the score has since been modified).
What does GCS 4 mean?
The levels of response in the components of the Glasgow Coma Scale are 'scored' from 1, for no response, up to normal values of 4 (Eye-opening response) 5 ( Verbal response) and 6 (Motor response) The total Coma Score thus has values between three and 15, three being the worst and 15 being the highest.
What is the JFK coma recovery scale?
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 . It may be used to differentiate between vegetative state (VS) and minimally conscious state (MCS). It can also be used to monitor emergence from minimally conscious state (EMCS or MCS+).
Which scale is best for DOC?
The conclusion was that the CRS-R was the most appropriate scale to assess DOC, scoring better than all the other scales examined, (which included SMART, WNSSP, SSAM, WHIM, DOCS).
What is the lowest score on the cognitive subscale?
The lowest score on each sub-scale represents reflexive activity; the highest represents behaviors mediated by cognitive input. The total score ranges between 0 (worst) and 23 (best). This measure takes a minimum of 25 minutes to complete.
What is the purpose of the Disorders of Consciousness Task Force?
The American Congress of Rehabilitation Medicine, Brain Injury - Interdisciplinary Special Interest Group set up a Disorders of Consciousness Task Force to conduct a systematic review of assessment scales for DOC (Disorders of Consciousness) and establish recommendations for use in clinical settings.
What is the JFK coma recovery scale?
The purpose of the scale is to assist with differential diagnosis, prognostic assessment and treatment planning in patients with disorders of consciousness. The scale consists of 23 items that comprise six subscales addressing auditory, visual, motor, oromotor, communication and arousal functions. CRS-R subscales are comprised of heirachically-arranged items associated with brain stem, subcortical and cortical processes. The lowest item on each subscale represents reflexive activity while the highest items represent cognitively-mediated behaviors. Scoring is standardized and is based on the presence or absence of operationally-defined behavioral responses to specific sensory stimuli. Adequate interrater and test-retest reliability have been demonstrated and concurrent validity has been established relative to the Disability Rating Scale. A recently-published review of behavioral assessment methods completed by European researchers recommended use of the CRS-R as a "new promising tool" for evaluation of consciousness after severe brain injury (Majerus, et al., 2005). Spanish, Italian, German, French, Dutch and Norwegian translations of the CRS-R are available.#N#Clinical and Research Applications#N#The diagnostic utility of the CRS-R was investigated by Giacino, Kalmar and Whyte in 2004. Eighty patients were assigned a diagnosis of VS or MCS following completion of the CRS-R and the DRS. In 51 of the 80 patients assessed, both scales produced a diagnosis of MCS. An additional 19 patients received a diagnosis of VS on both measures. The overall rate of agreement in diagnosis was 87%. There were no cases in which the DRS found evidence of MCS while the CRS-R did not. Conversely, there were 10 cases in which the CRS-R profile supported a diagnosis of MCS while the DRS findings were indicative of VS. In all 10 of these cases, the CRS-R detected evidence of visual pursuit, a diagnostic feature of MCS that is not represented on the DRS.
When was CRS R used?
The CRS-R has been utilized in TBI outcomes research and in large-scale epidemiologic studies. A 2005 Australian study of patients who were in MCS for at least one month after TBI used the CRS-R to document long-term outcome.

If you find the information in the COMBI useful, please mention it when citing sources of information. The information on the CRS may be cited as:
How often should a GCS be done?
An initial GCS should be done at time of admission and then every four hours unless otherwise indicated by the medical team. Documentation of the GCS is crucial since the medical team, which generally includes neurology, will use this to determine improvement or decompensation of the patient.
What is the lowest possible score for a scholastic test?
Each criteria is on a different scale with a total possible score of 15. The lowest possible score is 3.
Is the Glasgow Coma Scale accurate?
While the Glasgow Coma Scale is a great diagnostic tool there are multiple limitations that can alter the score and not provide an accurate picture of the patient’s brain injury. These include:
Does Glasgow coma scale measure brain injury?
Another significant limitation of the Glasgow Coma Scale, as it was originally developed, is that it does not accurately measure traumatic brain injury in children under 5 years of age. The aptly-named ‘Pediatric Glasgow Coma Scale (PGCS)’ includes modifications for this patient population.
What are the parameters of the Glasgow Coma Scale?
The Glasgow Coma Scale divides into three parameters: best eye response (E), best verbal response (V) and best motor response (M). The levels of response in the components of the Glasgow Coma Scale are ‘scored’ from 1, for no response, up to normal values of 4 (Eye-opening response) 5 ( Verbal response) and 6 (Motor response)
What is the Glasgow Coma Scale Pupils Score?
The Glasgow Coma Scale Pupils Score (GCS-P) was described by Paul Brennan, Gordon Murray, and Graham Teasdale in 2018 as a strategy to combine the two key indicators of the severity of traumatic brain injury into a single simple index. [13][14]
How to calculate GCS-P?
Calculation of the GCS-P is by subtracting the Pupil Reactivity Score (PRS) from the Glasgow Coma Scale (GCS) total score:
When was the Glasgow Coma Scale first published?
Introduction. The Glasgow Coma Scale was first published in 1974 at the University of Glasgow by neurosurgery professors Graham Teasdale and Bryan Jennett.[1] The Glasgow Coma Scale (GCS) is used to objectively describe the extent of impaired consciousness in all types of acute medical and trauma patients. The scale assesses patients according ...
What is a score in math?
The score is the sum of the scores as well as the individual elements. For example, a score of 10 might be expressed as GCS10 = E3V4M3.
What is NCBI bookshelf?
NCBI Bookshelf. A service of the National Library of Medicine, National Institutes of Health.
Is there a relationship between GCS scores?
A relationship between assessments of the GCS (typically reported as the total GCS Score) and the outcome was shown clearly by Gennarelli et al.,[10] who demonstrated the existence of a continuous, progressive association between increasing mortality after a head injury and decreases in GCS Score from 15 to 3( Figure2). This association has been seen in many other subsequent studies. The findings for the eye, verbal and motor responses also relate to the outcome but in distinctive ways so that assessment of each separately yields more information than the aggregate total score.
