What does it mean to be in a vegetative state?

A vegetative state is absence of responsiveness and awareness due to overwhelming dysfunction of the cerebral hemispheres, with sufficient sparing of the diencephalon and brain stem to preserve autonomic and motor reflexes and sleep-wake cycles.

What is the cause of coma?

This includes head injuries, loss of oxygen, bleeding or pressure in the brain, infections, metabolic problems, and toxic factors. Some specific examples include: traumatic brain injuries, such as those caused by traffic accidents or violent fights. stroke (reduced blood supply to the brain)

What is Glasgow Coma Score?

Glasgow Coma Scale. GCS was initially used to assess level of consciousness after head injury, and the scale is now used by first responders, EMS, nurses, and doctors as being applicable to all acute medical and trauma patients.
