Zusammenfassung:Reduced facial expression or amimia is one of the most typical characteristics of Parkinson's disease (PD). Despite being described in classic texts, its significance, physiopathology and correlation with motor and non-motor symptoms is largely unknown. We have studied facial bradykinesia in a group of 84 de novo PD patients prospectively evaluated for five years. We also studied the relationship of facial bradykinesia with depression in a subgroup of 30 patients. Baseline and follow-up assessments were performed with the Unified Parkinson's Disease Rating Scale (UPDRS). Baseline facial bradykinesia was rated according to item 19 of UPDRS. Baseline facial bradykinesia correlated with total and motor baseline UPDRS. In addition, baseline bradykinesia correlated with total and motor UPDRS at five years. However baseline bradykinesia did not influence the presence of motor (motor fluctuation, dyskinesias and freezing of gait) or non-motor complications (delusion, behavior abnormalities and dementia) at five years. Finally a subgroup of 30 patients completed the self-report version of the Quick Inventory of Depressive Symptoms (QIDS-SR16) questionnaire, facial bradykinesia did not correlate with QIDS-SR16 scores. Our study suggests that baseline facial bradykinesia correlates with general baseline situation in PD and even might predict the motor and functional status at five years.
