Mapping notes:The cohort study reports a broad "anxiety" diagnostic category rather than generalized anxiety disorder specifically; recorded here against GAD as the closest existing dismech disorder entry, but the underlying ICD/EHR coding likely spans multiple anxiety-disorder subtypes (including panic disorder, which the dedicated review below identifies as the more specific association).

"Psychiatric conditions showed heightened prevalence of anxiety (26.1%, OR 1.8, 95% CI 1.7-1.8, p < 0.001) and depression (18.7%, OR 1.3, 95% CI 1.2-1.3, p < 0.001)."

LITERATURE LITERATURE_ASSOCIATION UNKNOWN
Population:Narrative review of the joint hypermobility syndrome (JHS) and anxiety literature.
Mapping notes:This review's strongest documented association is specifically with panic disorder/agoraphobia, not GAD; recorded here as the closest existing dismech anxiety-disorder entry rather than as a precise match.

"JH shows an association with mitral valve prolapse and fibromyalgia. However, the most significant and important association between joint hypermobility syndrome (JHS) and any other disorder from a clinical point of view is with panic disorder."
Identifies panic disorder as the most clinically significant psychiatric association with joint hypermobility syndrome.

Hypotheses

Hypothesis (the "neurovisceral phenotype" model): joint hypermobility is associated with altered autonomic reactivity and heightened interoceptive sensibility; functional neuroimaging shows hypermobile individuals have heightened amygdala and insular cortex reactivity to negative emotional stimuli compared to non-hypermobile individuals. This constitutional difference in brain-body coupling is proposed to predispose to anxiety symptoms, rather than anxiety arising as a purely psychological reaction to chronic pain or disability.
PMID:25713509 (SUPPORT, review synthesis)
Source: HUMAN_CLINICAL
"In a recent functional neuroimaging study of healthy volunteers, hypermobile, compared to non-hypermobile, participants displayed heightened neural reactivity to sad and angry scenes within brain regions implicated in anxious feeling states, notably insular cortex (Mallorqui-Bague et al., 2014)."
Reports a specific functional neuroimaging finding of heightened amygdala/insular reactivity in hypermobile individuals, the structural correlate proposed to underlie the hypermobility-anxiety association.
PMID:20963520 (SUPPORT, review synthesis)
Source: HUMAN_CLINICAL
"JHS is more prevalent in individuals with panic disorder/agoraphobia, and patients with JHS present with greater prevalence of panic disorder/agoraphobia. In addition, there is an association between JHS severity and severity of anxiety"
A dedicated review of the joint-hypermobility/anxiety literature finds the strongest specific association is with panic disorder/agoraphobia, and that anxiety severity tracks hypermobility severity -- both arguing against a purely coincidental comorbidity.

  Anxiety is among the most consistently reported hEDS/joint hypermobility
  comorbidities, with the strongest specific literature association being to
  panic disorder/agoraphobia rather than generalized anxiety disorder (GAD)
  specifically. A large propensity-matched cohort found a broad "anxiety"
  diagnostic category in 26.1% of EDS patients versus matched controls (OR
  1.8); this is a broader anxiety-disorder category rather than a
  GAD-specific figure (see mapping_notes). The proposed "neurovisceral
  phenotype" model links hypermobility to anxiety through altered
  interoceptive/autonomic signaling and heightened amygdala/insular
  reactivity, rather than a purely psychological mechanism. Directionality
  is UNKNOWN. No ICEES KG signal exists for this pair: hEDS (MONDO:0007523)
  is not a node in the ICEES KG snapshot at all (confirmed while curating
  the hEDS-POTS comorbidity entry) -- note ICEES does separately carry a
  general "anxiety" node (MONDO:0011918), but that is moot without hEDS
  itself being present.
