A couple of questions about schizophrenia

1. How common is schizophrenia among children (e.g. 10-15 year old or even younger)?

Schizophrenia affects around 0.3–0.7% of people at some point in their life,[2] or 24 million people worldwide as of 2011.[107] It occurs 1.4 times more frequently in males than females and typically appears earlier in men[3]—the peak ages of onset are 20–28 years for males and 26–32 years for females.[108] Onset in childhood is much rarer,[109] as is onset in middle- or old age.[110] Despite the received wisdom that schizophrenia occurs at similar rates worldwide, its prevalence varies across the world,[111] within countries,[112] and at the local and neighborhood level.[113] It causes approximately 1% of worldwide disability adjusted life years.[3] The rate of schizophrenia varies up to threefold depending on how it is defined.[2]

2. Does schizophrenia has any cure? Is there any instance of a person being fully cured of it?

Schizophrenia is a major cause of disability, with active psychosis ranked as the third-most-disabling condition after quadriplegia and dementia and ahead of paraplegia and blindness.[95] Approximately three-fourths of people with schizophrenia have ongoing disability with relapses.[22] Some people do recover completely and others function well in society.[96] Most people with schizophrenia live independently with community support.[2] In people with a first episode of psychosis a good long-term outcome occurs in 42%, an intermediate outcome in 35% and a poor outcome in 27%.[97] Outcomes for schizophrenia appear better in the developing than the developed world.[98] These conclusions, however, have been questioned
