Frozen Sago Palms

Question

Recently we had a bad freeze in Austin, Texas, and I have two sago palms outside that were not protected. It got down to 19 degrees and now the leaves are brown. I do not know if the palms are damaged or not. It took about five years for the leaves to form. My question to you is: If the palms are still alive, what can I do get them back in good health?
