Generally, paranoid schizophrenia does not affect children. Typically, doctors diagnose the disorder between the time people are teenagers and the time they reach their mid-30s. However, doctors are now beginning to look for symptoms of schizophrenia more and more in younger individuals. If doctors can catch schizophrenia when people are young, they can usually do a better job of preventing the worst symptoms of the disorder. When paranoid schizophrenia does affect children, it seems to affect them in the same way that the disorder affects adults.
