Freezing. There is one peculiar sign of Parkinson’s disease, and it is called freezing. The patient is afraid to take the next step during a walk. Such symptom may be temporary but if freezing happens at the moment of turning there is a risk to fall down or to lose the body balance.

Lack of facial expression. Some people call that symptom “poker face” because the patient’s face may lose an ability to express emotions and feelings. Also, other people can notice your empty stare and rare eyes blinking. Never ignore the sign and connect with a doctor as soon as possible.
