Depression (16.2%) and migraine (11.6%) were the most common comorbidities. Medium\u2010efficacy injectable DMTs (interferon\u2010\u03b2 and glatiramer acetate) were associated with lower treatment persistence in patients with any comorbidity or psychiatric comorbidity during the 4\u2010year follow\u2010up. Among patients with psychiatric comorbidity, the rate of DMT discontinuation was high shortly after the DMT initiation, and the annualized relapse rate at the start of the DMT was higher compared with those without psychiatric comorbidity (1.3 [SD 0.78] vs. 1.1 [SD 0.74],\n                      <jats:italic>p<\/jats:italic>\n                      = 0.026).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Comorbidities, especially psychiatric diseases, are associated with lower persistence on injectable DMTs.
