"Death Wish" star Brosnan has been fighting Alzheimer's Disease for the past two years, and suffered organ failure earlier this month.
Doctors tending to the 81-year old have told his family to prepare for the worst and say their last goodbyes to the star.
A relative tells a British paper, "(The Alzheimer's) is heartbreaking. He doesn't know he was an actor, let alone a big star."
The "Great Escape" actor's wife Kim is now making final preparations to bring him home to die as he requested.
A friend adds, "Charlie's wife Kim promised him she would honor his wish to let him die with dignity."
