1 doctor agrees

In brief: It depends

There are many forms of coma.
With light coma the patient can be aware and remember everything that occurs around him. In deeper forms they may be aware but do not remember. In very deep forms there is no awareness or memory. It is very difficult for even highly trained observers to judge the level of coma. No specfic test is definitive. Assume they are aware until proven otherwise.
