Retired Army Colonel Don Gagliano, MD, knew something wasn't right after he came home from Iraq, where he had served as Medical Commander of the 30th Brigade. It took him a long time to seek treatment for PTSD. When he finally did, his doctor recommended Prolonged Exposure Therapy (PE), a cognitive-behavioral therapy shown to alleviate PTSD and its symptoms by helping patients confront traumatic memories they have been trying to avoid.
