Juvenile parkinsonism (JP) is a diverse neurological disorder, primarily caused by genetic and metabolic factors, not idiopathic Parkinson's disease. It often presents with additional neurological symptoms and systemic findings, requiring comprehensive evaluation.

Area of Science:

  • Neurology
  • Genetics
  • Pediatrics

Background:

  • Juvenile parkinsonism (JP) is a rare neurological disorder characterized by parkinsonian symptoms in individuals under 20 years of age.
  • Unlike adult Parkinson's disease, JP is predominantly caused by secondary factors, including hereditary and metabolic conditions.
  • Idiopathic Parkinson's disease is exceedingly rare in the pediatric population.

Purpose of the Study:

  • To provide a comprehensive overview of juvenile parkinsonism.
  • To elucidate the clinical characteristics, genetic basis, and pathophysiology of JP.
  • To discuss the classification, diagnosis, and management strategies for JP.

Main Methods:

  • This review synthesizes current knowledge on JP from existing literature.

  • It covers clinical features, etiological classifications, genetic underpinnings, and pathological findings.
  • The review also addresses biochemical aspects and therapeutic approaches.

    • Main Results:

    • JP is etiologically heterogeneous, with genetic and metabolic disorders being the primary causes.
    • Parkinsonism in JP is frequently associated with other neurological deficits like dystonia, cognitive impairment, seizures, and ataxia.
    • Systemic manifestations such as liver dysfunction may also be present.

    Conclusions:

    • Juvenile parkinsonism requires a distinct diagnostic and therapeutic approach compared to adult Parkinson's disease.
    • Understanding the diverse genetic and metabolic underpinnings is crucial for accurate diagnosis and targeted treatment.
    • Further research into the pathophysiology and novel therapeutic strategies for JP is warranted.
