Parkinson’s Disease – Symptoms, Impact, and Treatment Options

Overview of Parkinson’s Disease

Parkinson’s disease is a progressive neurological disorder that primarily affects movement. It occurs when the brain cells that produce dopamine, a chemical messenger that controls movement, are damaged or destroyed. This results in a range of motor and non-motor symptoms that can vary in severity from person to person.

Motor Symptoms:

  • Tremors
  • Bradykinesia (slow movement)
  • Rigidity
  • Postural instability

Non-Motor Symptoms:

  • Depression
  • Constipation
  • Sleep disturbances
  • Loss of sense of smell

Parkinson’s disease is more common in older adults, with the average age of diagnosis being around 60 years old. However, around 4% of people with Parkinson’s are diagnosed before the age of 50, a condition known as Young-Onset Parkinson’s.
According to the Parkinson’s Foundation, approximately 60,000 Americans are diagnosed with Parkinson’s each year, with over 1 million Americans currently living with the disease. The prevalence of Parkinson’s is expected to rise significantly as the population ages.

Common Motor Symptoms of Parkinson’s Disease

Parkinson’s disease is a neurodegenerative disorder that primarily affects motor function. The hallmark symptoms of Parkinson’s disease are related to movement, and they can vary in severity among individuals. Some of the common motor symptoms include:


One of the most recognizable symptoms of Parkinson’s disease is tremors, which are involuntary shaking movements that usually start in the hands or fingers. The tremors typically occur at rest and often disappear during purposeful movement.


Bradykinesia refers to slowness of movement and is another key feature of Parkinson’s disease. Individuals may experience difficulty initiating movement, have reduced arm swing while walking, or exhibit a general slowness in their actions.

Muscle Rigidity

Muscle rigidity is characterized by stiffness or resistance to passive movement in the limbs or torso. This stiffness can contribute to difficulty in performing everyday tasks and can lead to muscle pain and discomfort.

Postural Instability

Postural instability is a common symptom in later stages of Parkinson’s disease and can result in impaired balance and a greater risk of falls. Individuals may have difficulty maintaining an upright posture or changing positions smoothly.


Dyskinesia refers to involuntary, erratic, and uncontrollable movements that can be a side effect of long-term use of levodopa, a common medication for Parkinson’s disease. These movements can be disruptive and impact daily activities.

It’s important to note that not all individuals with Parkinson’s disease will experience the same combination or severity of motor symptoms. The presentation of symptoms can vary widely, and the progression of the disease is unique to each person.

Surveys and Statistical Data on Motor Symptoms

According to the Parkinson’s Foundation, approximately 60,000 Americans are diagnosed with Parkinson’s disease each year. The prevalence of motor symptoms like tremors, bradykinesia, and muscle rigidity increases with age, and Parkinson’s disease is more common in individuals over the age of 60.

A survey conducted by the Michael J. Fox Foundation found that tremors are the most prevalent motor symptom reported by individuals living with Parkinson’s disease, followed by bradykinesia and muscle rigidity. These symptoms can have a significant impact on daily functioning and quality of life for individuals affected by the disease.
