What assessments are included in the four score Coma Scale select all that apply?

The Glasgow Coma Scale (GCS) is the most common scoring system used to describe the level of consciousness in a person following a traumatic brain injury. Basically, it is used to help gauge the severity of an acute brain injury. The test is simple, reliable, and correlates well with outcome following severe brain injury.

The GCS is a reliable and objective way of recording the initial and subsequent level of consciousness in a person after a brain injury. It is used by trained staff at the site of an injury like a car crash or sports injury, for example, and in the emergency department and intensive care units.

The GCS measures the following functions:

Eye Opening (E)

  • 4 = spontaneous
  • 3 = to sound
  • 2 = to pressure
  • 1 = none
  • NT = not testable

Verbal Response (V)

  • 5 = orientated
  • 4 = confused
  • 3 = words, but not coherent
  • 2 = sounds, but no words
  • 1 = none
  • NT = not testable

Motor Response (M)

  • 6 = obeys command
  • 5 = localizing
  • 4 = normal flexion
  • 3 = abnormal flexion
  • 2 = extension
  • 1 = none
  • NT = not testable

Clinicians use this scale to rate the best eye opening response, the best verbal response, and the best motor response an individual makes. The final GCS score or grade is the sum of these numbers.

Using the Glasgow Coma Scale

A patient's Glasgow Coma Score (GCS) should be documented on a coma scale chart. This allows for improvement or deterioration in a patient's condition to be quickly and clearly communicated.

Individual elements, as well as the sum of the score, are important. The individual elements of a patient's GCS can be documented numerically (e.g. E2V4M6) as well as added together to give a total Coma Score (e.g E2V4M6 = 12). For example, a score may be expressed as GCS 12 = E2 V4 M6 at 4:32.

Every brain injury is different, but generally, brain injury is classified as:

  • Severe: GCS 8 or less
  • Moderate: GCS 9-12
  • Mild: GCS 13-15

Mild brain injuries can result in temporary or permanent neurological symptoms and neuroimaging tests such as CT scan or MRI may or may not show evidence of any damage.

Moderate and severe brain injuries often result in long-term impairments in cognition (thinking skills), physical skills, and/or emotional/behavioral functioning.

Limitations of the Glasgow Coma Scale

Factors like drug use, alcohol intoxication, shock, or low blood oxygen can alter a patient’s level of consciousness. These factors could lead to an inaccurate score on the GCS.

Children and the Glasgow Coma Scale

The GCS is usually not used with children, especially those too young to have reliable language skills. The Pediatric Glasgow Coma Scale, or PGCS, a modification of the scale used on adults, is used instead. The PGCS still uses the three tests — eye, verbal, and motor responses — and the three values are considered separately as well as together.

Here is the slightly altered grading scale for the PGCS:

Eye Opening (E)

  • 4 = spontaneous
  • 3 = to voice
  • 2 = to pressure
  • 1 = none
  • NT = not testable

Verbal Response (V)

  • 5 = smiles, oriented to sounds, follows objects, interacts
  • 4 = cries but consolable, inappropriate interactions
  • 3 = inconsistently inconsolable, moaning
  • 2 = inconsolable, agitated
  • 1 = none
  • NT = not testable

Motor Response (M)

  • 6 = moves spontaneously or purposefully
  • 5 = localizing (withdraws from touch)
  • 4 = normal flexion (withdraws to pain)
  • 3 = abnormal flexion (decorticate response)
  • 2 = extension (decerebrate response)
  • 1 = none
  • NT = not testable

Pediatric brain injuries are classified by severity using the same scoring levels as adults, i.e. 8 or lower reflecting the most severe, 9-12 being a moderate injury and 13-15 indicating a mild TBI. As in adults, moderate and severe injuries often result in significant long-term impairments.

I had a GCS of 15 but from what my mom estimates based on it, I probably was a 10. I was in a bus accident going 50 and we were hit head on by a car going 90-100+. In the ER which I don't remember at all, they asked me my name and it took me a few minutes, and I could not remember the year or president.

Looking back, I should have been sent to Cooper Trauma in Camden or CHOP in Philly. I had a stroke about 4 days later, it was mild thank god, but still, I was 15.

I had a GCS of 3 for 2 weeks, then periods of agitation as became slowly more aware, then a presumed delirium with fluctuating GCS.
Having a brain injury/Coma is survivable, anyone with concerns about their selves or a loved one in this situation please try and be optimistic, I know that's easy to say and hard to do.
I consider myself very lucky even having some minor disabilities now, I have little bit of trouble with concentration and memory and toes on left foot being numb and my right leg is numb from the hip down and I have to wear a splint from knee down. But that being said I consider myself lucky, I spent 3 months in hospital, 2 of which were in stroke/brain injury rehabilitation, and some of my fellow patients on ward had bigger hills to climb than me.
Extremely humbling,
Think the point I'm trying to make is "where there's life there's hope" We have some wonderful health care workers who don't get the acclimation they deserve sometimes. They saved my life, and I wish the best to anyone who is in this situation, be it their selves or a loved one.

Reading through these comments bring back so much pain, I just lost my dad to a horrible car accident. He lost control of his vehicle and suffered many injuries, his whole left side of his brain had a stroke, he literally started swelling within 24hrs of his car accident. His GCS score was 3 and writhing the days of him being in the trauma center he was not on any sedation and his score remained a 3. I hate thinking that drs did not do everything in their power to save him. He was so young and it hurts so bad, I guess I just hate knowing that a lot of my family members who I have lost have died in that hospital. I don’t even know what to think! I just can’t come to terms with it, I kept telling the drs on face time. Please do everything you can for him! Remember to you he is just a check, you will have another case today tomm the next but to me that is my dad a brother a grandpa a husband. I guess it was just so hard because through the entire process because of covid we were not allowed to be by his side. We only got one hr one hr before he passed.

He is in acute renal failure, on a ventilator, no sedation, and still unresponsive. They said his crit level is a 7 and climbing and want to start dialysis. Not sure he will pull thru with a constant GSC of 5 of 8 days. Any feedback? He is a drug addict and did have meth laced with fentanyl in his system.

I was in a bad car wreck going 65mph in a head on collision in Alaska. I didn’t hit my head on anything but I was shaken very badly (only know this because the seat belt locked so tight that it almost cut me in half but wouldve been thrown and died if I wasn’t wearing it). Since I was unconscious, I don’t remember how long I was out for. I lost consciousness and woke up when the first responders got there. If the first responders responded from the station to the crash site, it’s a 20-30 min drive. It’s a 20 min drive to the hospital from the crash site. I lost consciousness at 5 times. They ended up intubating me and putting me on a ventilator. About a week later, I was weaned off of the sedation and had been med evac’d to the continental US. I have migraines on a daily basis and the migraines vary in severity. I have dizziness. I used to have 20/20 vision. When I woke up, I could only see 6 inches in front of my face. I now wear glasses with prescription, prisms due to convergence difficulty, and tint due to light sensitivity. I’m having difficulty reading and believe I might have acquired dyslexia. I used to be intelligent. I graduated at 16 from high school and went to college for pre med. After my wreck, I can’t even do simple math. I have difficulty remembering details and recent things that happened when before I had a photographic memory and could remember everything that I was told once. The MRI doesn’t show anything. I’ve been diagnosed with a mild TBI and neck injury at the Polytrauma at the VA. The new hospital that I’ve been sent to blames my neck injury and tries to say that I don’t have a TBI even though they firs saw me a year after the injury. I believe I have a moderate TBI because it’s been 2 yrs and my symptoms are worsening not getting better. The TBI clinic I’m going to isn’t helping me at all. When I bring in valid questions, I’m told that’s not a thing or you don’t have that without being examined. When I bring in scholarly articles about my valid questions, I’m told “Well I’m not the subject matter expert”. If the PA over my case is not the subject matter expert then why is she working at a physician in the TBI clinic? I’m trying to find a new clinic to go to. I live in San Antonio, TX

Good that you are going to find a doctor or other medical professional (vestibular/vision/psychological, etc.) who gets it, even if you still have to keep going to that doctor for insurance purposes or whatever.

My husband was in a motorcycle accident, he was thrown from his bike he was not helmeted, he had gave his helmet to a passenger. Well he was GCS 3. The severity of his injury was so bad that he had 3 hemorrhages which was non-operable...He was on a ventilator I was told he could not breathe on his own, non reactive to light, pain stimuli, NOTHING. The neurologist advised us that his prognosis was very poor. He had 5CT Scans with no change. He was swelling on day 2, the family decided without me to take him off the ventilator.. they were advised he would not last no more than 30min but he held on for 9hrs BREATHING ON HIS OWN but gave up....I just got his medical records and read through them... he was intoxicated at the time of the accident, which could affect his tests etc. I believe if he lasted 9hrs before he passed, if they only left him on for a week to really see if there would be any changes, but because the swelling was so severe and they could not relieve the swelling the family decided to take him off. I’m more upset I wasn’t involved in that decision. Please have hope, trust your gut instinct because the doctors aren’t always right, they said my husband wouldn’t last 30min without the ventilator but he lasted 9hrs!!! I’m devastated my husband was only 34.

So sorry that happened to you Rebecca. My son was hit by a car Dec.2011...severe TBI gsc 3...died twice...2 major seizures...was in a coma for 2 months and when he came out of it he was in a semi vegetative state..no eye contact..no talking...just rocking back and forth and rubbing his head and drooling. Drs said I need to put him in a care home where he can age safely and securely...24 yrs old. We could not accept that. As a family we did every possible thing to help him recover...14 hours a day...constant therapy. Music... touch stimulation...3 brothers holding him upright while I was on the floor moving his feet...I stayed in that province for almost a year. Every time he made a bit of progress the dr would say that was coincidence or that's all he will be able to do. I took over his complete care so he wouldn't be a burden on the nurses as I was scared they were going to xfer him to a care home. Almost one year later Corey walked out of that hospital with the exact same personality he had before ..has every memory from childhood ..makes us laugh every day. He will always have to live with us as the accident left him with short term memory loss and some cognitive impairments so he's on disability but his sight came back after about a year! We also weaned him off all the antipsychotic medications they had him on...terrible stuff!! Everyone out there..have hope and remember that Drs are not Gods!!

Thank you for sharing. I almost died 4 years ago. Slipped and fractured skull, I remember hearing the sound of ocean waves and knew I was dying. I lived alone and remained unconscious for 4 days. I had a tremendous amount of healing to do but the crazy part is, I didn’t tell anyone. I felt as just what you said - the doctors arent god and I was alive by a miracle. I didn’t want to hear fright and doom and took control of my healing. It was incredibly difficult to do but foods and herbs helped. Two years later I went in for mri’s I was still suffering a major concussion. But after I woke I had vomiting, dizziness, hearing problems, eyesight issues. My hair sheds out a lot today and I still have a soft spot where my skull fractured. I have a touch of dyslexia and have a hard time concentrating on reading but I knew I survived by a miracle and am back to myself but actually more improved. I believe something saved me so I could fulfill a purpose.

What doctors have forgotten is God that is the supreme and able to do things against drs' expectations. brain is not just something physical but relates to soul and metaphysical entities which we may not see or understand. in a coma, our brain cells need time to reconstruct and revive; drs just give up and many of them do not believe in God.

I hope you will believe me when I say it's best not to dwell on the "what ifs." You'll drive yourself crazy. I worked in an ICU and saw some people recover from horrible injuries, but most did not. If they weren't able to relieve the pressure on his brain, he would have herniated and the results would be the same. I have seen that there are worse things than death, from work and in my own life. My grandfather lived in a miserable state for 20 years after he survived being taken off the ventilator. He had a stroke after a brain aneurysm repair at 58 years old, so he lived with the damage from the stroke for all of that time. He was confined to a wheelchair, then bedridden for the last 3 years of his life. He only knew my grandmother, my mom, and his 3 other children. I felt like I lost my grandfather the day he went into the hospital for the aneurysm repair. My sister was flown by helicopter after being found unresponsive in her recliner at home. She had been there for 3 days. We still don't know what happened, I have suspicions about her odd neighbors since she had some trauma to her head on both sides, not something that would happen if she had fallen before sitting in her recliner. Her MRI was terrible. She had suffered a stroke or lack of oxygen to her brain, or both, they weren't sure, she was only 46 years old. Her brain was swelling, and she didn't respond to anything. I noticed she began to posture, which indicates severe brain damage. I knew that even if she survived and could breathe on her own, she would be in a vegetative state. We decided to take her off of the ventilator. It was 13 hours before she finally passed. I feel we made the right decision, but I wish I knew what had happened to her. I don't know why you weren't the one making the decisions since the spouse is the next of kin and I don't like it when physicians tell people that the person will pass away quickly, it's unrealistic to predict such things. More often than not, it takes longer if the person isn't absolutely brain dead. I'm so sorry for your loss, I hope you can find peace.

Hello! I don't know the extent of her injuries but, I was in a car accident almost 4 years ago and I believe my GCS score was 3-5, I was in a coma for 10 days and had paralysis on the right side of my body. Physically I have fully recovered, I had to relearn how to walk so I still have a very slight limp. However during my recent research of TBIs I have come to learn that TBIs start as acute (when they first happen) and turn into chronic TBIs (over time it becomes worse neurologically) as it turns into a chronic TBI, the psychological effects of the injury become worse due to the effect it has on the brains neurotransmitters. As far as I put together (I'm no doctor) my injury has effect on my serotonin, dopamine, and acetylcholine levels (probably effect other neurotransmitters, I have only researched these so far) and the TBI causes a deficit in these neurotransmitters. These deficits have caused a lack of motivation, sleeping all the time, memory, attention, learning and processing speeds, these are typical signs of depression, I am not sad, just experiencing symptoms of depression do to my brain injury affecting my neurotransmitters. From my research a SSRI and dopamine agonists/DARI (dopamine reuptake inhibitors) will help reduce these affects. I have yet to go to a psychologists to get these drugs. Do some research of how TBIs affect the neurotransmitters! She might not need them now but in a few years he might, definitely tell her or care giver to mention this to doctors, I waited 4 years to get help and my condition has only gotten worse, I can barely pass basic college classes now, with this information in her doctors hands can improve his doctors life! I've also read that Deep brain stimulation (DBS) can bring people out of vegetative states

What is the Four Score neurological assessment?

The FOUR Score tests crucial brainstem reflexes and provides information about the severity of brainstem injury which are unavailable with the GCS. The FOUR Score recognizes a locked-in syndrome and a possible vegetative state. The FOUR Score includes signs suggesting brain herniation.

What does a GCS score of 4 mean?

• Obeys commands for movement 6 points. • Purposeful movement to painful stimulus 5 points. • Withdraws in response to pain 4 points. • Flexion in response to pain (decorticate posturing) 3 points. • Extension response in response to pain (decerebrate posturing) 2 points.

What is the value of 4 score?

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.

What are the 3 responses that the Glasgow Coma Scale is scoring?

The GCS is scored between 3 and 15, 3 being the worst and 15 the best. It is composed of three parameters: best eye response (E), best verbal response (V), and best motor response (M).
