Stage II is considered a moderate form of Parkinson’s, and the symptoms are much more noticeable than those experienced in stage I. Stiffness, tremors, and trembling may be more noticeable, and changes in facial expressions can occur. While muscle stiffness prolongs task completion, stage II does not impair balance.
Patients at this stage feel symptoms on both sides of the body and sometimes experience speech difficulties. The progression from stage I to stage II can take months or even years. There is no way to predict individual progression.
