Hi, Gogoblu. I can't speak to schizophrenia. But for bipolar in kids:
There is lack of a definitive diagnostic consensus, but there is strong agreement on the following:
Grandiosity, very rapid cycling, daredevil behavior, excessive risk-taking, sustained rages, extreme sleep difficulties and night terrors, depression, mania. In some cases, also psychosis. Plus co-occuring ADHD is par for the course, not to mention anxiety.
A bipolar child is generally a lot sicker than a bipolar adult. Medical and psychosocial and educational interventions are no-brainers, whether one chooses to call it bipolar or something else.
We are not talking about merely over-active kids who may benefit from a bit more TLC or parental discipline. We are talking about kids living in internal hells experiencing a condition that confounds even the experts.
Diagnosis requires extremely close observation, with strong family input. The diagnositic tie-breaker is often whether BP runs in the family. Treatment is often problematic, but there is every reason to have faith that the child will grow up to lead a productive and rewarding life if action is taken.
Doing nothing - as a lot of people who should know better suggest - is an invitation to disaster.
You would not typically diagnosis schizophrenia in someone under 18. Schizophrenia does not usually have onset until someone is in their 20's, usually late 20's early 30's. I don't see children so I am not sure if there is a diagnosis you would us under 18 to acknowledge that but children can have make believe out of touch thinking without it being a mental illness. Children are diagnosis with bipolar and bipolar can have psychotic episodes. If a child is has a sever case of Type 1 bipolar you can have extreme grandiosity, delusional thinking and psychotic breaks. I can not think of any symptoms that could not be explained by bipolar which would be dramaticly more likely in that age range.
