Compared to other recognized clinical symptoms, the personality profile of WD patients remains under-investigated. This study compared personality traits in a sample of adults with WD and healthy controls (HC). Moreover, we assessed the cognitive and affective correlates of personality within the WD group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We enrolled 20 patients affected with genetically confirmed WD, with prevalent extrapyramidal symptoms, and 20 age and education-matched HC.

Among WD patients, neuroticism correlated with global disability, trail making test, depression, and mental health status; psychoticism correlated with memory and executive functions (all r\u2009&gt;\u2009\u00b1\u20090.5).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We observed that WD patients are characterized by high neuroticism and psychoticism, and this personality profile is related to other clinical, cognitive, and neuropsychiatric manifestations.
