What Is The Median Age At Which Depression Manifests?

For phobias (7–14, IQR 4–20) and impulse control disorders (7–15, IQR 4–35), the median and interquartile range (25th–75th percentiles) of AOO are significantly sooner than for other anxiety disorders (25–53, IQR 15–75), mood disorders (25–45, IQR 17–65), and substance use disorders (18–29, IQR 16–43). The median age of onset (AOO) for non-affective psychosis is between the ages of late teens and early twenty. More than three-quarters of all long-term mental problems begin in the teens or early twenties, according to most research. In most cases, secondary disorders are responsible for later onsets. In most cases, less severe illnesses precede the more severe ones, and it is rare for these to be brought to the attention of a doctor.
