While some studies reported elevated rates of depression and anxiety among patients with LS, the available evidence is limited by often small sample sizes, cross-sectional designs, narrow matching, and limited consideration of sex- or race-disparities. Moreover, the risk of a broader spectrum of psychiatric disorders remains insufficiently characterized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To evaluate the risk of a larger spectrum of psychiatric disorders following a diagnosis of LS in a retrospective cohort study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      The US Collaborative Network of TriNetX was used to create a propensity-score-matched cohort of individuals with LS and non-LS controls (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f42,581 per cohort). Risk of psychiatric disorders following the index events was analyzed in a retrospective cohort study. Several sensitivity analyses were conducted to assess robustness of the findings.
