To understand the difference between Parkinsonism, Parkinson’s Plus Syndromes/atypical Parkinsonism, and Parkinson’s Disease, consider the following points:

• Definition: Parkinsonism refers to a group of neurological disorders that cause movement problems similar to Parkinson’s disease.

• Cause: Parkinson’s disease is a specific neurodegenerative disorder primarily caused by the loss of dopamine-producing neurons.

• Symptoms: Both conditions exhibit tremors, rigidity, and bradykinesia, but parkinsonism may include additional symptoms depending on the underlying cause.

• Types: Parkinsonism can result from various factors, including medications, toxins, or other diseases, while Parkinson’s disease is a distinct diagnosis.

• Diagnosis: Parkinson’s disease is diagnosed based on clinical criteria, while parkinsonism may require further investigation to identify the underlying cause.

• Treatment: Treatment for Parkinson’s disease often includes medications like levodopa, while parkinsonism treatment focuses on addressing the specific cause.

Parkinson’s Plus Syndromes (also called atypical Parkinsonism disorders) are a group of progressive neurodegenerative diseases that cause the symptoms of Parkinsonism Plus additional neurological problems.

The four major Parkinson’s plus syndromes are:

• Multiple System Atrophy (MSA)
  
  • Parkinsonism plus problems with blood pressure, bladder function, sexual function, or coordination.
• Progressive Supranuclear Palsy (PSP)
  
  • Early falls, difficulty moving the eyes (especially looking down), balance problems, and changes in speech or swallowing.
• Corticobasal Degeneration (CBD)
  
  • Severe stiffness affecting one side more than the other, difficulty using one limb, involuntary movements, and cognitive changes.
• Dementia with Lewy Bodies (LBD)
  
  • Parkinsonism combined with early dementia, visual hallucinations, fluctuating alertness, and sleep disturbances
