The transition to adulthood can be difficult for young adults who suffer from a serious mental illness, such as schizophrenia or bipolar disorder. When these individuals are unsuccessful, the result can be economic hardship, social isolation, and in some cases suicide, all of which can pose substantial costs to society. Due to concerns about young adults with serious mental illness transitioning into adulthood, this book provides information on (1) the number of these young adults and their demographic characteristics, (2) the challenges they face, (3) how selected states assist them, and (4) how the federal government supports states in serving these young adults and co-ordinates programs that can assist them.
