In this monocenter, observational, non-interventional, prospective, open label study investigators will enrol 43 CD patients from the outpatient Movement Disorders Clinic of the Department of Human Neurosciences, Sapienza University of Rome. As this is a non-interventional study, no diagnostic, therapeutic or experimental intervention is involved. Subjects will receive clinical assessments, medications and treatments solely as determined by their study physician. The BoNT-A injection will be performed in CD patients at baseline. As this is an observational, non-interventional study, the injection protocol for BoNT-A treatment is upon physicians' decision. All CD patients will undergo up to three evaluations of motor and non-motor symptoms: before (baseline) and 1 month and 3 months after botulinum toxin treatment. Both evaluations will be carried out under the same conditions. Motor symptoms will be assessed in all CD using the Comprehensive Cervical Dystonia Rating scale (CCDRS) (Comella et al, 2015). Non-motor symptoms including psychiatric, psychological and sleep disorders will be investigated. Psychiatric symptoms will be assessed with CCDS, Hamilton Rating Scale for Anxiety (HAM-A) and the Hamilton Rating Scale for Depression (HAM-D); the psychological symptoms will be assessed with the demoralization scale (Kissane et al, 2004) and the Italian Perceived Disability Scale (Innamorati et al,2009). Sleep disorders will be investigated with the Pittisburg Sleep Quality Index (PSQI) (Buysse et al, 1989).
