| Outline of Final Research Achievements |
To clarify pathophysiology of the masked face in Parkinson disease (PD), we analyzed temporal changes of facial expression using motion capture technique. We also investigated the relationships between masked-face and cognitive / affective symptoms and investigated neural substrate for masked-face using neuroimaging analyses. As a result, we studied 38 PD patients and 24 healthy controls, and we found a significant decrease of facial expression in the PD group. In addition, facial expression score was associated with psychological score such as attention / executive function, and depression scores. Furthermore, the resting state fMRI analysis showed significant differences in functional connectivity mainly in the frontal lobe in the PD with sever masked-face group. We concluded that the masked face of PD might be related to not only motor symptoms but also cognitive affective disorders.
