The last chapter, written by all three editors of the volume, is dedicated to an overview and future prospects in the field. This book is designed for everyone interested in the field of panic disorder. This is certainly a good and well-thought-out book, but, like any other comprehensive review book, it portrays a constantly changing field at a single point in time. Unfortunately, the most recent findings, such as the importance of the clinical comorbidity between panic and bipolar disorder (2, 3), testimonies of the new clinical leadership in psychiatric research, are not included. The problem of writing a comprehensive book on a constantly changing topic can be compared to the famous Achilles-turtle paradox of Zeno of Elea. Like Achilles, even when running as fast as he is able, the editor of this type of book can hardly reach the progress of empirical research and the constant renewing of hypotheses in the field.
