ANTHONY SALERNO, PH.D.: Thank you.
MARTY MOSS-COANE: Let me begin with you, if I can, Nathaniel, to talk a little bit about your father. You were young when he began to lose his grip on reality. What do you remember as a little boy? What do you remember in terms of how your father began to change?
NATHANIEL LACHENMEYER: Prior to onset he had been a very loving and caring parent. As he began to change, the progression was slow and he became slightly hostile and aggressive -- not toward me, but toward other people. It wasn't until after my parents were divorced that it really became schizophrenia, and at that point I would receive calls and letters that were openly delusional and references to the government and a conspiracy that involved my family and things like that.
MARTY MOSS-COANE: You write about how your father began to look different. He had a different face.
NATHANIEL LACHENMEYER: He did early on. I think it was mainly the tension and probably having to negotiate the emerging symptoms and try still to be who he had been. He never recognized the fact that he was ill, so from his perspective he was grappling with an ongoing conspiracy, but even that had a definite physical imprint on him.
