What Is GCS Score and How Is It Used to Evaluate Brain Injury Severity?

Question

When my uncle had a stroke last month, I heard the doctors repeatedly mentioning his GCS score while monitoring his condition. At the time, I had no idea what it meant, but after some research, I found out that GCS score stands for the Glasgow Coma Scale, a system used to assess a person's level of consciousness. However, I am still struggling to fully understand how it works.

From what I have read, the GCS score ranges from 3 to 15, where 15 means full alertness and 3 means deep unconsciousness. But what does a specific GCS score indicate about a person’s condition? For example, if someone has a GCS score of 8, does that mean they are in a coma? How quickly can a GCS score change, and what factors influence improvement or decline?

Another question I have is whether a GCS score can predict recovery. If someone starts with a low GCS score, is there a good chance of improvement with the right medical and therapeutic support? Or does a low score always indicate permanent damage?

I am also interested in whether Ayurveda offers any treatments for improving brain function after a low GCS score. Are there specific herbs, dietary recommendations, or lifestyle changes that can support brain healing and nerve regeneration? I have heard that Brahmi, Ashwagandha, and Shankhpushpi are used for brain health—could they help in this case?

If anyone has experience with a loved one recovering from a low GCS score, I would love to learn more about the rehabilitation process and what helped in their recovery.

The Glasgow Coma Scale (GCS) score is a crucial tool used by doctors to assess a person's level of consciousness after a stroke, brain injury, or other neurological events. It evaluates three key responses: eye opening (E), verbal response (V), and motor response (M)—with a total score ranging from 3 to 15. A score of 8 or below typically indicates a severe brain injury and suggests the person is in a coma or deeply unconscious state. However, GCS scores can change over time based on medical interventions, brain swelling, and the body's ability to heal. A gradual improvement in the score often indicates better brain function and recovery potential, while a declining score may signal worsening neurological damage.

Recovery from a low GCS score depends on several factors, including the severity of brain damage, age, overall health, and speed of medical treatment. Some patients regain consciousness and gradually recover with rehabilitation and therapy, while others may have long-term impairments. Ayurveda supports brain healing through herbs, diet, and holistic therapies. Brahmi, Ashwagandha, and Shankhpushpi are well-known for their neuroprotective properties, helping to improve memory, nerve regeneration, and cognitive function. Medhya Rasayanas (brain-rejuvenating formulations) and therapies like Shirodhara (warm oil therapy on the forehead) can aid in calming the nervous system and promoting healing.

To support post-stroke recovery, Ayurveda emphasizes a Sattvic diet rich in healthy fats (ghee, nuts, seeds), fresh fruits, vegetables, and whole grains to nourish the brain. Nasya therapy (nasal administration of medicated oils like Brahmi oil) is believed to enhance oxygen supply to the brain and improve cognition. Pranayama, meditation, and gentle yoga can also help increase oxygen circulation and reduce stress, which plays a role in neurological healing. While Ayurveda can complement conventional stroke recovery, it’s essential to work alongside medical professionals for the best outcomes. If your uncle's condition is stable, consulting an Ayurvedic doctor for personalized recommendations could be beneficial in supporting his rehabilitation.
