Anxiety, the latest volume in the Vitamins and Hormones series first published in 1943, and the longest-running serial published by Academic Press, provides up-to-date information on the roles that hormones and other factors play in anxiety and stress. Each volume focuses on a single molecule or disease that is related to vitamins or hormones, with the topic broadly interpreted to include related substances, such as transmitters, cytokines, growth factors, and others thoroughly reviewed.
