When Jenny and Alan Buchanan became foster parents to Mark in November 2010, the 6-month-old infant was blind, deaf and stiff from cerebral palsy, all the result of abusive head trauma, more commonly known as “shaken baby syndrome.” He required an 18-hour feeding tube and doctors said he would never walk or talk. “His doctor said take him home, love him — in three months he won’t be here,” said Alan Buchanan, a printer from Colchester, Vermont, who with his wife has two grown daughters and two grandchildren. “We expected to do end-of-life care.” Mark was taken from his abusive family at 5 weeks old and placed in a pediatric nursing home. He had suffered from three skull fractures, two broken collar bones and a broken toe, some of them older wounds, at the hands of one or both of his parents. “We don’t know which parent and no one was ever charged,” Buchanan, 65, told NBC News. About 25 percent of the victims of abusive head trauma die, according to the Centers for Disease Control and Prevention. Of those who survive, like Mark, 80 percent suffer permanent disabilities and brain damage.
