Because minimally conscious state is a relatively new criterion for diagnosis, there are very few functional imaging studies of patients with this condition. Preliminary data has shown that overall cerebral metabolism is less than in those with conscious awareness (20–40% of normal [3]) and is slightly higher but comparable to those in vegetative states.
In a minimally conscious state, the patient has intermittent periods of awareness and wakefulness. The criteria for minimally conscious state, that patients are not in a vegetative state but are not able to communicate consistently. This means, that patients have to show limited but reproducible signs of awareness of themself or their environment.
A vegetative state (VS) or post-coma unresponsiveness (PCU) [1] is a disorder of consciousness in which patients with severe brain damage are in a state of partial arousal rather than true awareness. After four weeks in a vegetative state, the patient is classified as being in a persistent vegetative state (PVS).

He recovered to the point that he was able to become a web designer, developer, and author. In 2011, he wrote a book called Ghost Boy, in which he describes his many years of being comatose.

Time is the best general predictor of a chance of recovery. For example, after four months of coma caused by brain damage, the chance of partial recovery is less than 15%, and the chance of full recovery is very low. [50] The outcome for coma and vegetative state depends on the cause, location, severity and extent of neurological damage.
A 34-year old, who was believed to be in an unconscious vegetative state after suffering cardiac arrest 16 years ago, was shown the 1961 'Alfred Hitchcock Presents' episode "Bang! You're Dead."
Given the absence of any accepted criterion of the minimal neuronal correlates necessary for consciousness, the distinction between a persistently vegetative patient who shows regular sleep-wave transitions and may be able to move or smile, and a minimally conscious patient who can communicate (on occasion) in a meaningful manner (for instance ...
Terry Wayne Wallis (April 7, 1964 – March 29, 2022) was an American man from the Ozark Mountains of Arkansas who, on June 11, 2003, regained awareness after spending 19 years in a minimally conscious state.
