Hypomimia and Methods of Its Diagnostics in Patients with Parkinson’s Disease

Abstract

Objective of the Review: To present information of hypomimia manifestations and methods of its diagnostics in patients with Parkinson’s disease (PD) used in scientific trials and clinical practice. Key Points. One of the most significant manifestations of PD is hypomimia. Most commonly, this syndrome is evaluated using the unified PD rating scale which allows analysing patient’s hypomimia subjectively. There are studies which are based on objective methods for computeraided hypomimia diagnostics. Conclusion. To the date, there is insufficient information regarding objective characteristics of hypomimia. The issue of interrelation between hypomimia and generalised hypokinesia and possible cross-correction of these syndromes remains unclear. It is necessary to develop an objective, affordable and simple method for facial expression assessment to be used in routine neurological practice. Keywords: Parkinson’s disease, hypokinesia, mimics, hypomimia, videoanalysis.
