In this study, quality of life and psychiatric comorbid disorders were investigated in patients with cervical dystonia and their spouses and we also investigated the effect of botulinum toxin (BTX) treatment on these parameters. ⋯ In our study, an increase in psychiatric comorbid disorders such as depression and anxiety was observed and the quality of life was adversely affected in all areas in patients. In the spouses of the patients, the rates of psychiatric comorbid disorders such as depression and anxiety were found to be increased when compared to healthy subjects while vitality, mental health, and general health perception were found to be negatively affected. Patients showed improvements in anxiety level, disease activity, and overall quality of life scales after BTX treatment.
