Some symptoms of Parkinson's disease are tremors, progressively slower movement and speech, poor balance and posture and difficulty writing. Symptoms of Parkinson's disease generally appear mild at first and gradually worsen over time, say experts at Mayo Clinic. Symptoms vary among patients, but generally include changes in speech, coordination and muscle movement.
The onset of Parkinson's often produces symptoms first only in one side of the body, according to Mayo Clinic. As the disease spreads, symptoms appear in both sides, but are usually more severe in the side first affected.
One classic sign of Parkinson's is a tremor, which usually starts in one hand or the fingers. The trembling of a resting hand may indicate Parkinson's, as can a pill-rolling tremor, where the forefinger and thumb rub together.
Gradually slowing movement and muscle stiffness are other possible indicators of Parkinson's. Those affected may start to shuffle when they walk and have trouble rising from a seated position. Muscle stiffness can occur throughout the body, causing limited movement and pain.
Loss of automatic movement may cause the person with Parkinson's to have a decreased ability to perform unconscious movements such as blinking or even smiling, explains the Mayo Clinic. Muscle stiffness may occur in any of part of the body. Stiff muscles bound any movement and cause pain.
Parkinson's may cause changes in speech and unconscious movements or reflexes. People with Parkinson's may pause before speaking, slur their words or have a change in voice fluctuation. They may have trouble blinking, smiling and coordinating arm movements when walking.
