Age at onset of mental disorders worldwide: Large-scale meta-analysis of 192 epidemiological studies. Molecular Psychiatry. https://doi.org/10.1038/s41380-021-01161-7
    The studies included in this meta-analysis measured this age in different ways. Some studies looked at the age when symptoms of the disorder began, some looked at when they were first diagnosed, and others looked at when they first received treatment for the disorder or were first hospitalized for it. The median age of onset for some disorders, such as substance use disorders, mood disorders and anxiety disorders was earlier when it was measured by first symptoms than when it was measured by first diagnosis or first hospitalization.
