The 2022 International Working Group defines a minimally conscious state (MCS) as a state of severe altered consciousness with minimal clear behavioral evidence of perception of self and environment. Studies have shown that patients with MCS have more intact neural networks preserved by severe brain damage, and unlike persistent vegetative states, patients with MCS have the potential to revive and have a better prognosis, with continued improvement in consciousness after 6 months. The diagnosis of minimal consciousness must be based on the repeated or persistent presence of one or more of the following behaviors to demonstrate a limited but clear cognitive ability of self and surroundings. 1. compliance with simple commands 2. the ability to answer yes or no with posture or language, regardless of correctness 3. intelligible language 4. purposeful behavior, including occasional movements and clear responses related to environmental stimuli, rather than involuntary movements.
