One day several years ago, I was reaching the end of my first visit with a patient, J.J., who had come to see me for anxiety and insomnia. He was a salesman for a struggling telecommunications company, and he was having trouble managing the strain on his finances and his family. He was sleeping poorly, and as soon as he opened his eyes in the early morning, the worries began. “I wake up with a list of things to worry about,” he said. “I just go through the list, and it seems to get longer every day.”
A psychiatric interview has a certain rhythm to it. You start by listening to what your patient says for a few minutes, without interrupting, all the while sorting through possible diagnoses. This vast landscape of distress has been mapped into a series of categories in psychiatry’s diagnostic manual, DSM-IV. The book breaks down mental suffering into 16 groups of disorders, like mood disorders, anxiety disorders, psychotic disorders, eating disorders and several others. As I listened to J.J. (a nickname that he agreed I could use to protect his privacy), it was clear to me that he had one of the anxiety disorders, but which one? In order to systematically rule in or rule out the disorders, I asked J.J. dozens of questions. “Do you have panic attacks?” “Do you get fearful in crowded situations?” “Have you ever experienced a traumatic event that later caused flashbacks or nightmares?”
Each of J.J.’s answers provided me with a clue, closing off one possibility while opening up others. At its best, when you are working with an intelligent, insightful patient, the process is fun, involving a series of logical calculations, much like working a Sudoku puzzle. Finally, toward the end of the hour, I felt confident that I had arrived at J.J.’s diagnosis. “I think you have what we call ‘generalized anxiety disorder,’ ” I told him. It may start with a defined series of causes, as was true for J.J., but then it spirals outward, blanketing the world with potential threat. J.J. worried about what the future would bring and experienced a predictable series of physical symptoms: insomnia, muscle tension, irritability and poor concentration.
“I’m going to write you a prescription for a medication called Zoloft,” I said, picking up my prescription pad. He asked what was causing his anxiety, and I began one of the stock neurochemical explanations that psychiatrists typically offer patients about low serotonin levels in the brain. The treatment involved “filling up the tank” by prescribing a medication like Zoloft, Celexa or Paxil.
