The locked-in syndrome: The early French descriptions.

The classic 1966 description of locked-in syndrome was performed by Plum and Posner. Here, we revisit the world's first case report of this condition, which was presented in 1875 by Camille Darolles, an intern supervised by François Damaschino, at a monthly meeting of the Société Anatomique de Paris chaired by Jean-Martin Charcot. We also review the fascination of classic writers with this syndrome, including Alexandre Dumas, a genius of literature and known admirer of the medical sciences who, in the book "The Count of Monte Cristo" published in 1846, described a character with this condition.
