Adolescence is both the peak period of onset for MDD and a time of pronounced sleep disruption, yet the mechanisms linking disturbed sleep to depression risk remain poorly understood. We propose that brain criticality, an EEG measure of neural dynamics and information processing capacity, offers a novel putative mechanistic lens to understand this relationship. In adolescence, criticality may be perturbed by sleep disturbance through both a short\u2010term failure of nightly restoration and long\u2010term progressive shifts in the developing brain's baseline set point. We outline how depression\u2010related deviations from criticality could reflect a shifted set point, altered drift, or failed reset, each predicting distinct clinical presentations. Because these metrics can be extracted from existing EEG data, they offer an immediately translatable tool for risk stratification and mechanism\u2010targeted treatment in adolescent depression.<\/jats:p>","DOI":"10.1111\/jcpp.70233","type":"journal-article","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T03:47:13Z","timestamp":1789012033000},"page":"1793-1795","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Editorial: Criticality: a novel brain metric associated with sleep that may elucidate sleep's influence on adolescent depression"],"prefix":"10.1111","volume":"67","author":[{"given":"Alison","family":"Huckenpahler","sequence":"first","affiliation":[{"name":"Department of Psychiatry Washington University in St Louis  St. Louis MO USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5352-1721","authenticated-orcid":false,"given":"Joan","family":"Luby","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Washington University in St Louis  St. Louis MO USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Hoyniak","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Washington University in St Louis  St. Louis MO USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pcl.2011.03.003"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1516-13.2013"},{"key":"e_1_2_2_4_1","doi-asserted-by":"crossref","unstructured":"Mitsuto A.
