Background and Objectives: Personality change is an important psychiatric complication following stroke linked to severe affective dysregulation and behavioral alterations. Methods: We investigated personality traits in 20 patients (age 45.37 ± 13.41 years) with subacute stroke submitted to rehabilitation training within 1–3 months after a first-onset stroke. All patients underwent psychological evaluation by using the Personality Inventory for DSM-5 for adults (PID-5), a specific instrument that enables traits (dimensions and facets) to be assessed by providing a personality profile, and the Inventory of Interpersonal Problems 47 (IIP-47), a brief and valid self-report measure for screening personality disorders. Results: Personality change was identified by a positive correlation IIP-47 and PID-5 (r = 0.76; p = 0.03). Our patients, after a stroke, presented maladaptive personality traits associated with negative affect such as anxiety, emotional lability, and rigid perfectionism, and they reported interpersonal problems. These negative affective disorders correlated positively with cluster C personality disorders, including the avoidant, dependent, and obsessive compulsive personality disorders. Conclusion: Preliminary results show personality changes in stroke survivors. The evaluation of personality changes could be useful to improve the management of the patient’s behavioral alterations in a familiar environment and permit the possibility of prevention of psychological distress of the patients and their respective caregivers.
