Human development across the lifespan

Meet the patient — and the question her mother is really asking

A 16-year-old is brought in after cutting her arm. She is bright, socially anxious, and absorbed in whether she is "a real person". She started smoking cannabis three months ago, hangs out with older peers, and her sleep has inverted. Her mother asks the only question that matters to her: "Is this a phase, or is this who she is?"^[5][6]

Every developmental stem is really two questions wearing one mask: is this expected development, and is there pathology riding on top of it? A consultant separates them by stage, by timing, and by trajectory — never by gut alone. This topic is the toolkit for doing that at fellowship depth.^[4][6][7]

Etymology for viva gold: adolescence comes from the Latin adolescere, "to grow up" — the same root as adult. The word itself says these are people mid-becoming, which is exactly why a single cross-sectional snapshot misleads you.^[5]
