Get a copy of the book The Bipolar Child: The Definitive and Reassuring Guide to Childhood's Most Misunderstood Disorder by Papolos and Papolos.

Also google "Child and Adolescent Bipolar Foundation" for a parent's support group.

What you describe does not sound like bipolar to me, but then I am not a parent and not a psychiatrist.

The sensory issues sound like they could lead you to a solution. Some people find improvement with diet changes -- like going wheat and gluten free.

Abilify can be an agitating medicine for adults -- of course in children these meds can work differently.
