Vascular parkinsonism (VP) is a controversial condition often misdiagnosed. This review clarifies VP definitions and distinguishes it from idiopathic Parkinson's disease (IPD) based on clinical signs and imaging.

Area of Science:

  • Neurology
  • Neuroscience
  • Vascular Neurology

Background:

  • The concept of vascular parkinsonism (VP) lacks clear definitions, leading to diagnostic confusion.
  • Incidental vascular lesions in idiopathic Parkinson's disease (IPD) are more common than VP.
  • Distinguishing VP from IPD and other parkinsonian syndromes is challenging.

Observation:

  • VP is clinically heterogeneous, often presenting atypically.
  • Typical VP shows focal neurological signs and lacks resting tremor, akinesia, and levodopa response seen in IPD.
  • Vascular pseudoparkinsonism specifically affects gait, differing from IPD gait disturbances.

Findings:

  • Common VP lesions include basal ganglia lacunes and Binswanger-type white matter vasculopathy.
  • Rarely, VP results from single striatal infarcts or substantia nigra ischemia.

  • The pathophysiology of VP remains poorly understood, with lesion load not fully explaining parkinsonism development.

    • Implications:

    • Clearer definitions are needed to delineate the VP spectrum.
    • Understanding VP pathophysiology is crucial for accurate diagnosis and treatment.
    • Differentiating VP from IPD is essential for appropriate patient management.
