N2 - Introduction: Non-motor features of cervical dystonia (CD) have been identified, including depression, anxiety, and neuropsychological deficits. The aims were: to provide a clinical neuropsychological profile of CD patients with specific focus on social cognition; assess levels of psychological distress; and investigate the relationship between non-motor features of CD, including cognitive functioning, psychological distress, CD severity, pain, and health-related quality of life (HR-QoL). Methods: A multi-domain neuropsychological assessment battery was administered to 46 participants with CD, examining cognitive and social cognitive domains. Clinical data on dystonia severity, pain, psychological distress and HR-QoL were collected. Results: The majority of participants with CD performed within the average range across most tests of cognition. Scores were significantly lower than standardized norms in social cognition, processing speed, and aspects of memory. High levels of anxiety (Hospital Anxiety and Depression Scale [HADS-A] ≥ 11, 30%) and depression (HADS-D ≥ 11; 29%) were observed. Psychological distress, CD severity, pain and HR-QoL were not significantly associated with neuropsychological functioning after controlling for multiple comparisons. Low HR-QoL was associated with higher levels of pain and psychological distress, but not severity of motor symptoms. Conclusion: Results indicate that psychological distress and deficits in cognitive and social cognitive functioning are likely distinct features of CD. While motor symptoms do not appear to impact HR-QoL, pain and psychological distress were associated with low HR-QoL. Findings highlight the importance of addressing non-motor symptoms in the treatment of CD.
