Parkinson’s disease is a progressive disorder of the nervous system that affects our movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while tremor may be the most well known sign of Parkinson’s disease, the disorder also commonly causes stiffness or slowing of movement.
In early stages of Parkinson’s disease, your face may show little or no expression, or your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson’s disease symptoms worsen as your condition progresses over time. Although Parkinson’s disease can’t be cured, medications may markedly improve your symptoms. In occasional cases, your doctor may suggest surgery to regulate certain regions of your brain and improve your symptoms.
Parkinson’s disease symptoms and signs may vary from person to person. Early signs may be mild and may go unnoticed. Symptoms often begin on one side of your body and usually remain worse on that side, even after symptoms begin to affect both sides.
Parkinson’s signs and symptoms may include:-
- Tremor. Your tremor, or shaking, usually begins in your limb, often your hand or fingers. You may notice a back and forth rubbing of your thumb and forefinger, known as a pill-rolling tremor. One characteristic of Parkinson’s disease is tremor of your hand when it is relaxed.
- Slowed movement (bradykinesia). Over time, Parkinson’s disease may reduce your ability to move and slow your movement. This may make simple tasks difficult and time consuming. Your steps may become shorter when you walk, or you may find it difficult to get out of a chair. Also, your feet may stick to the floor as you try to walk, making it difficult to move.
- Rigid muscles. Muscle stiffness may occur in any parts of your body. The stiff muscles can limit your range of motion and cause you pain.
- Impaired posture and balance. Your posture may have become stooped, or you may have balance problems as a result of Parkinson’s disease.
- Loss of automatic movements. In Parkinson’s disease, you may have a decreased ability to perform unconscious movements, including blinking, smiling or swinging your arms when you walk. You may no longer gesture when talking.
- Speech changes. You often may have speech problems as a result of Parkinson’s disease. You may speak softly, quickly, slur or hesitate before talking. Your speech may be more of a monotone, rather than with the usual inflections.
- Writing changes. Writing may appear small and become difficult.
