In a talk at the 2015 meeting of the International Society for Bipolar Disorders, researcher Eric Youngstrom showed that mothers’ evaluation of their children’s psychiatric symptoms was more valid than both teacher ratings and the children’s own evaluations. Parents were better at detecting irritability, while children were better at assessing their energy levels and the quality of their sleep.
Youngstrom reported that about 2% of children worldwide are diagnosed with bipolar disorder. However, when bipolar disorder not otherwise specified (BP NOS), a diagnosis given when symptoms do not meet the diagnostic criteria for Bipolar I or II, is included in the statistics, rates of bipolar disorder among children in the US reach about 6%.
Youngstrom mentioned that an epidemiological study by Kathleen Merikangas found that among children in the US with a bipolar spectrum diagnosis, only 22% were in treatment, compared to 38% of those with depression and 60% of those with ADHD.
Parents of children (aged 2–12) with mood, anxiety, and behavioral disorders are invited to join the Child Network, our program for tracking weekly symptoms which can then be printed out longitudinally to share with the child’s doctor.
