ABSTRACT: The aim of our study was to determine self-awareness of dyskinesias and other core motor symptoms in Parkinson's disease (PD) through the use of movie presentations. A scale based on 10 movies (five depicting dyskinesias and five showing core symptoms) and the Self-Assessment Parkinson's Disease Disability Scale were administered to 21 patients (all with a Mini-Mental State Examination - MMSE score ≥ 25). Neurological assessment included the Unified Parkinson's Disease Rating Scale and the Hoehn-Yahr and Schwab-England scales. In addition, the MMSE, Beck Depression Inventory and Stroop task were administered. Overall, patient and caregiver ratings of dyskinesias and core PD symptoms were consistent. Two patients (9%) completely denied dyskinesias, while four patients (19%) significantly underestimated their dyskinesias. Our results confirm that poor self-awareness of symptoms in PD may be selective and that denial of dyskinesias affects only a minority of patients with normal cognitive status (MMSE ≥ 25). Most patients are aware of the presence of dyskinesias. Poor self-awareness of dyskinesias is associated with longer disease duration.
