The final chapter, a summary by the editors of the previous contributions, appears to recognize, on reflection, many of the issues that have not been addressed and devotes individual short paragraphs to such things as bipolar disorder in children and adolescents, treatment decisions during pregnancy and the postpartum state, mania in the elderly, and the effect of gender on course and treatment. A number of questions regarding how to translate observational findings into clinical decision making are raised and answered in a staccato two pages at the end of the volume.
