@boomerang,
Schitophrenia with children starts at the age of about seven, eight but before 13 years aka
Very Early Onset Schizophrenia (VEOS).
It's later called
Early Onset Schizophrenia (EOS), that is before the child is 18.
But though it happens rarely, the psychiatric children hospital for our region deals with about 20 patients per year stationary and about about 10 in day care (in three day care clinics) (600 children per year stationary).
