I thought of a couple other things after I posted last night.
1) Do your DD's moods have a seasonal component? Do you see them getting more intense during fall or spring? My DD has a significant downturn every fall as the days get shorter. The depressive phase really takes hold. We started using a light box last fall to counteract this. I notice a difference with it. A lot of parents of bipolar kids will notice an increase in manic behaviors in the spring as the days get longer.
2) Depending on what study you look at, between 50% and 90% of bipolar children will have comorbid ADHD. In these cases, it's important to get her mood stabilized before trying to treat the ADHD symptoms.
3) You may want to have her evaluated for sensory difficulties.
Agree with Maggie'sMom: Many bipolar people are affected by the seasons, thus adding Seasonal Affective Disorder to the laundry list of issues, but light therapy works great and get her outside as much as possible when weather is appropriate. Also, outdoor exercise is like a triple whammy for me: 1. She is getting some sunlight; 2. she is exercising and pumping up her endorphins which seem to be so much more stabilizing than meds as well as good mood inducers; and 3. she's distracted. I am lucky enough to live near several areas that have great walking paths near rivers, streams, nature centers, etc. and if I see her come off the bus with that look (and you know the one), I immediately throw plan B into action and we head out the door to give her quiet, outdoor stimulation (and I alway have a small snack bag ready, just throw in cool drinks). Homework can wait, it won't happen anyway if there is a meltdown so avoid, avoid, avoid the drama and redirect the energy.
Another great book is
The Bipolar Child by Demitri Papalos, M.D. They have it at
Amazon but our psych doctor gave us a copy, and it isn't a cheap book either, nice hardcover edition.

Very good info in there.
Also agree on M'sM on the comorbid ADHD. Our psych will not let DD be on ANY ADHD meds until all her bipolar meds are adjusted and working correctly. This did cause an issue with one of her teachers (and myself) in the beginning, but I see what he means now and am willing to let him get the main problem worked out first and then we will retackle the ADHD issues.
My DD has sensory issues, too. Teeth brushing is a BIG deal as well as how her blankets are on her when she goes to sleep; she says her ears 'hear too much'. They can vary from child to child, but it is possible your DD is VERY overstimulated and her senses are too in-tune. KWIM?
Hope all this helps, you can always message me.

And always remember, pick your battles. With a BP kid what we may think is just a tiny little thing we ask them to do can be the catalyst to set them into a rage. Ask yourself, is it worth a rage? Can it wait until her mood is more stable and we can talk? BP kids cycle much faster than BP adults, you can often see a child cycle many times in one day. Learn your child's cycles, start keeping a notebook. It will be very helpful when you go to the doctor and you can pinpoint dates and times of rages, exuberance, giddiness, crankiness, anger, depression, clingy-ness, etc. (And yes, many kids go through these emotions, BP kids just go through them nonstop.)
