Facial Masking
Facial expressions basically involve many complex, subtle muscle movements. Those with Parkinson’s disease usually have a worsened ability to show their facial expressions, which is also known as facial masking. The muscles in your face will move more rigidly and slowly than usual. As a result, those people often appear emotionless or blank, although their emotional abilities aren’t impaired. In some cases, facial masking could also make you blink eyes slower. This makes it more difficult for them to communicate with other people. [4]
