What Is the Difference Between Parkinson's and Parkinsonism?

Understanding neurological disorders can be complex, especially when terms sound so similar.

One frequently asked question is: What is the difference between Parkinson's and Parkinsonism? While these conditions share many symptoms, they are not the same. Knowing the distinction can be essential for patients, caregivers, and healthcare providers navigating diagnosis and treatment.

What Is the Difference Between Parkinson’s and Parkinsonism?
Parkinson’s disease is a progressive neurological disorder that primarily affects movement. It is caused by the gradual loss of dopamine-producing neurons in a part of the brain called the substantia nigra. This dopamine deficiency leads to hallmark symptoms such as tremors, muscle rigidity, slowness of movement (bradykinesia), and balance problems.

Parkinsonism, on the other hand, is a broader term used to describe a group of conditions that share similar motor symptoms with Parkinson’s disease, such as tremors, stiffness, and slowness. However, Parkinsonism may have different causes, and not all forms of it respond well to traditional Parkinson’s medications like Levodopa.

So in short:

• Parkinson’s disease is a specific diagnosis.
• Parkinsonism refers to any condition that causes similar movement symptoms, including but not limited to Parkinson’s disease.

Types of Parkinsonism
There are several different types of Parkinsonism, each with unique features and underlying causes. These include:

• Multiple System Atrophy (MSA): A rare condition affecting the autonomic nervous system in addition to movement.
• Progressive Supranuclear Palsy (PSP): Characterized by balance issues and difficulty with eye movements.
• Corticobasal Degeneration (CBD): Often leads to severe stiffness and difficulty with limb coordination.
• Drug-induced Parkinsonism: Caused by certain medications that interfere with dopamine, such as some antipsychotics.

These conditions tend to progress more rapidly than Parkinson’s disease and are less likely to respond to dopamine-replacement therapies.

Diagnosis and Treatment
Diagnosing Parkinson’s vs. Parkinsonism involves a combination of clinical evaluation, neurological exams, and response to medications. Imaging tests like DaTscan may help support a diagnosis but cannot always clearly distinguish between the two.
Treatment approaches differ. Parkinson’s disease often responds well to dopamine-enhancing medications, while some forms of Parkinsonism do not. Physical therapy, occupational therapy, and speech therapy are commonly recommended for both to help manage symptoms and maintain quality of life.

Support for Those Affected
If you or a loved one has been diagnosed with Parkinson’s or any form of Parkinsonism, support and education are essential. That’s where organizations like the Parkinson’s Association of Southwest Florida (PASWFL) come in.

For over twenty-five years, PASWFL has provided effective programs and services that improve the quality of life, educate, enrich, and empower our Southwest Floridians touched by Parkinson’s disease and related neurological disorders. Each week, PASWFL offers more than 25 free programs and support groups for individuals with PD and their care partners.
