Eligible studies included cross\u2010sectional, cohort, case\u2013control, and case series designs reporting pain, psychiatric symptoms, or sleep disturbances in HFS. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal tools according to study design.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty\u2010two studies met inclusion criteria. Headache was reported in varying frequencies, ranging from 24.2% to 60% of cases, and facial pain in 33.3%, both frequently improving after botulinum toxin (BoNT) therapy. Psychiatric comorbidities were prevalent, with depression and anxiety reported in 5.7% to 29% and 9.1% to 19.5% of patients, respectively. Sleep disorders, mainly insomnia, occurred up to three times more often in HFS patients than in controls. BoNT therapy demonstrated beneficial effects beyond motor control, reducing pain, anxiety, and depressive symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>HFS is a multidimensional disorder with substantial non\u2010motor burden.
