No, he has a form of ADHD. You see it in the classroom all the time.
The ADHD kid can't stay still so fidgets and walks around the room at every opportunity, makes sounds in the background of discussion, talks over other children and the teacher, loudly demands clarification of even simple tasks. They draw attention to themselves in whatever way possible, often messing with the school uniform. In Bear's case, he wears face paint and masks.
For the past two weeks Chloe kept Bear distracted and literally gave him something to do and it will have been the same on Shipwrecked and EotB. Now Chloe has gone I expect him to get more restless and distracted.
That's all it is though. No personality disorders or mental illness.
