Introduction

All parents can relate to the many changes their kids go through as they grow up. But sometimes it's hard to tell if a child is just going through a "phase," or showing signs of something more serious.

In the last decade, the number of children receiving the diagnosis of bipolar disorder, sometimes, called manic-depressive illness, has grown substantially.1 But what does the diagnosis really mean for a child?

This booklet discusses bipolar disorder in children and teens. For information on bipolar disorder in adults, see the National Institute of Mental Health (NIMH) booklet Bipolar Disorder in Adults.
