Coma patients may seem to be asleep all the time or they may
sleep,wake up,move and make sounds.(1) the patient
may seem to be “awake” sometimes,their brain remains unconscious
and cannot be woken up.(2) ,they are not able to form a
connection with other people or the world around them.(3)

harm to the brain and the coma is brief, patients often return to
normal but with some loss of memory or other brain fun_ction.
