5. Weakened Facial and Throat Muscles

As the illness starts to progress, the symptoms of Parkinson’s disease will become more obvious. At the advanced stage, the patient will start to notice some changes in his or her speech pattern, as well as facial appearance. The face will have a fixed and vacant expression, which some call as the “Parkinson’s mask.”

The weekend facial muscle will prevent the patient from making proper facial expressions, such as frowning, smiling, and laughing. In the same way, the weakened muscles in the throat will make the person unable to speak properly. The patient will also find it hard to cough, choke, and drool.
