Frequency of disorder of consciousness (DoC) diagnoses by Glasgow Coma Scale (GCS) total score. The GCS comprises three subscales: eye opening, motor, and verbal responses. There are 120 possible combinations of subscale scores, each of which can be associated with a DoC diagnosis. All scores other than 3 and 15 are associated with multiple DoC diagnoses. Scores of 7–11 have the largest number of potential subscale combinations. The “N” below each GCS total score indicates the number of possible GCS subscale score combinations for each GCS total score. For example, there are 18 different ways a GCS total score of 9 could be achieved. rPTCS, recovered from PTCS (best GCS subscale score is GCS verbal = 5); PTCS, post-traumatic confusional state (best GCS subscale score is GCS verbal = 4); MCS+, minimally conscious state with evidence of language function (best GCS subscale score is GCS verbal = 3 or GCS motor = 6); MCS-, MCS without evidence of language function GCS (best GCS subscale score is GCS motor = 5); VS/UWS, vegetative state/unresponsive wakefulness syndrome (best GCS subscale score is GCS eye opening >1 or verbal = 2).
