Parkinson's Disease Symptoms

What are the Symptoms of Parkinson's Disease?

Early Symptoms of Parkinson's Disease

Early symptoms are hard to detect and may go unnoticed for years.^[1][2] They usually begin on one side of the body and are always worse on that side. Early in the disease there may be mild tremors (shaking). People may have trouble getting out of a chair or have small, cramped handwriting. They may lose track of a thought or word. They may feel tired, irritable or depressed for no apparent reason. This early period can last for a long time before the more classic and obvious symptoms appear.

Classic, Later Symptoms of Parkinson's Disease

The classic symptoms that appear later include:

• Tremors. Parkinson's disease typically causes shaking. This may begin with a hand. Many people, however, may not experience tremors with the disease.
• Slowed motion. With time, the disease may make it more difficult to move. This can make even simple tasks difficult. Steps may be slow and shuffling or it may be difficult to start walking.
• Muscle stiffness. The muscles of the limbs and neck may be stiff and there may be painful cramps.
• Impaired posture and balance. Someone with the disease may become stooped over. Problems balancing are also common.
• Loss of automatic movements. Movements that normally require no thought such as blinking or smiling become difficult or impossible. Some people may lose all facial expressions. Some people may have trouble swallowing. Others may lose control over the bowel or bladder.
• Speech changes. There may be problems with talking including speaking too softly, too rapidly, in a monotone, or with slurring. People may repeat words or hesitate before speaking.
• Dementia. In the later stages of the disease, people may have problems with memory and may be confused.
• Depression. This may occur before other symptoms but is easily treated.
• Skin problems. Oily skin, especially on the forehead and sides of the nose, is common. Others may have very dry skin. Sweating is also a common symptom.
• Sleep problems. Difficulty sleeping is common. People may be restless during sleep and experience nightmares.
• Emotional changes. Some people with Parkinson's disease may become fearful and insecure. They may not want to travel or socialize. Others may be irritable or pessimistic.
• Dizziness or fainting upon standing. A sudden drop in blood pressure may occur when standing up and fainting may occur. This can be treated effectively.
• Fatigue and loss of energy. Being tired may be associated with the difficulties of coping with the disease or it may be due to depression or sleep problems. It may also be the result of muscle problems.
• Sexual problems. Men may experience erectile dysfunction. This is often treatable.
