To the Editor: I was very pleased to read the study by Mardi J. Horowitz, M.D., and colleagues R501559BCEEBAFH investigating a new diagnosis to include symptoms of turbulent grief. We need a better, deeper, and fuller understanding of the grief process. This well-designed study has already contributed to our appreciation of the specific features of grief in contrast to depressive diatheses. I would, however, like to challenge the criteria upon which the authors base their recommended diagnosis.The authors hinge their phenomenological findings on a 14-month time period for grieving spouses. In my clinical experience, the duration of grief reactions does—and should—vary widely depending on the nature of the loss and the connection to the deceased. A parent grieving over the loss of a child may have "unbidden memories" and many of the other "complicated grief" symptoms R501559BCEDBADF for many months past 14 without their necessarily indicating a pathological process. Indeed, we would be troubled were it otherwise. On the other hand, these same symptoms significantly present even 1 year after the death of a distant, elderly, and unfamiliar relative would be highly suggestive of pathology R501559BCEBBBGJ.
