This is the 3rd edition of the seminal work about children and bipolar disorder. The only reason it stars so low is because it is already 9 years old, and should serve only as the starting point to your research, not the final word. Hopefully they'll print a new edition at some point.
But, basically, what you get here is the beginning of everything you ever wanted to know about bipolar disorder in children. The Affordable Care Act has made chapter 13 completely obsolete, but apart from that, this is darned useful and comprehensive, from symptoms, getting a correct diagnosis, meds, working with schools to create an IEP/504 plan, and, if necessary, how to handle hospitalization. The focus is younger children rather than teens, though there is one short chapter on adolescence for kids with bipolar.
As with any consumer health book, cross-check the info with your doctor and ask lots of questions!! You will also want to supplement with a Medline search, or the consumer health databases at your local library, if any (call and ask).
