[ILADVOCATE]

"If one parent has bipolar disorder a child has about a 12-15% chance of developing the disorder. If both parents are diagnosed the risk climbs to about 25%."
"It is being increasingly recognized that bipolar disorder often has its onset in adolescence or early adulthood. First affective symptoms appear in early teenage, and even in preadolescence. There is a growing interest, with little consensus, in the affective and behavioral symptomatology in childhood and adolescence preceding the first onset of a clearly diagnosable bipolar disorder. There is a significant time-lag between the onset of the illness and first treatment. This may put patients at risk of increased morbidity, including  effects on personality, school, work and social functioning. There is growing evidence in the schizophrenia literature that this time-lag may predict a poorer response to treatment. Although there is no clear evidence of this in bipolar disorder, this issue should be borne in mind."
These quotes are from clinically accurate websites. As for what medications would be used that would depend on the individual person but there are some websites linked up on the welcome page that would provide more information on currently used mood stabilizers and their side effects. The genes for bipolar run throughout my extended family so some parents did watch for it out of concern and there were some times it happenned but its not a given. It is a legitimate concern though.
