(CNN) Doctors are not optimistic one of the men stabbed at a New York Hanukkah celebration will regain consciousness, according to the victim's family.

Josef Neumann, who was one of five people assaulted Saturday in the upstate hamlet of Monsey, suffered multiple stab wounds to his head, neck and arms, his family said in a statement posted to social media by the Orthodox Jewish Public Affairs Council. Shoshana Bernstein, a spokeswoman for the Orthodox Jewish community in Monsey, said the statement is accurate.

"Doctors are not optimistic about his chances to regain consciousness, and if our father does miraculously recover partially, doctors expect that he will have permanent damage to the brain; leaving him partially paralyzed and speech-impaired for the rest of his life," the statement said.

The family described Neumann's condition as dire and said a weapon "penetrated his skull directly into the brain." His right arm was shattered.

"Our father has seven children, many grandchildren, a great grandchild, and brothers and sisters," the statement said.
