In brief: Any age

Depending on the disorder, serious mental illness can occur from infancy through old age.
Specific disorders often have a "window" of maximum vulnerability, e.g., autism with the very young and schizophrenia in late teens/early 20s. Others, like depression and anxiety, are spread out throughout the life course. Some may result from specific events, but many relate to brain development.
