Analysis of variance and chi square tests measured differences in patient characteristics across the three disease groups. Using ADSD as the referent, multivariable logistic regression models were used to determine whether potential risk factors including patient demographics, family history, presence of potential inciting events prior to disease onset, and coprevalent movement disorders were associated with ADSD\u2009+\u2009LT or LT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In all, 652 patients with ADSD (n\u2009=\u2009377), ADSD\u2009+\u2009LT (n\u2009=\u200998), and LT (n\u2009=\u2009177) were included. ADSD patients were significantly younger than those with ADSD\u2009+\u2009LT and LT (52.5\u2009\u00b1\u200913.4, 63.9\u2009\u00b1\u200911.3, and 69.3\u2009\u00b1\u200910.5 years, respectively; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Coprevalent movement disorders were more common in ADSD\u2009+\u2009LT (38.7%) and LT (57.1%) groups than in the ADSD group (11.5%; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Compared to ADSD, patients with ADSD\u2009+\u2009LT and LT were more likely to develop an additional movement disorder during follow\u2010up. In multivariable analyses, increasing age, female gender, and having a movement disorder at presentation were associated with significantly greater odds of having ADSD\u2009+\u2009LT or LT when compared to ADSD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>ADSD\u2009+\u2009LT patients demonstrate intermediate gender composition and age distributions between those with ADSD and LT.
