This review considers whether many such labels index context-bound expressions of common threat-regulation processes rather than independent mechanisms. A mechanism-first account is developed from experience to process to biological implementation: threat appraisal under uncertainty, interoceptive inference, and attentional control are proposed as content-general operations through which diverse cues recruit a conserved defensive architecture. Human neuroimaging, psychophysiology, and comparative evidence are broadly compatible with this account but do not establish mechanistic identity. In particular, non-significant cross-domain differences cannot demonstrate equivalence without formal equivalence testing or Bayesian evidence, and the diphasic autonomic response in blood-injection-injury phobia constitutes a genuine boundary case, suggesting that a shared appraisal core may feed more than one effector profile. The shared-process account is therefore treated as a parsimonious, falsifiable hypothesis. It generates predictions and boundary conditions for cross-context neural generalization, autonomic equivalence, reliable cognitive transfer, and latent structure, together with designs capable of distinguishing common processes from domain-specific mechanisms. Classifying anxieties by process rather than label could improve measurement, sharpen mechanistic tests, and guide transdiagnostic interventions while avoiding premature reification of context-specific constructs.</p>","PeriodicalId":93496,"journal":{"name":"Psychoradiology","volume":"6 ","pages":"kkag029"},"PeriodicalIF":7.4,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13621305/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149083225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structurally, children with ADHD exhibit delayed overall thalamic volume development and significant atrophy in specific subregions, such as the ventral anterior nucleus, mediodorsal nucleus, and pulvinar. Regarding white matter microstructure, projection pathways from the thalamus to regions such as the motor cortex and striatum are impaired. Both resting-state and task-fMRI consistently demonstrate weakened cortical connectivity between the thalamus and both the default mode and dorsal attention networks.
