A subgroup of patients with progressive supranuclear palsy (PSP) presents with frontal symptoms but progresses to typical PSP. This frontal presentation does not alter the overall prognosis for patients with PSP.

Area of Science:

  • Neurology
  • Neurodegenerative Diseases

Background:

  • Progressive supranuclear palsy (PSP) is a rare neurodegenerative disorder.
  • Early misdiagnosis can occur due to atypical presentations.

Purpose of the Study:

  • Investigate the clinical presentation of PSP.
  • Examine the relationship between initial diagnosis and survival.

Main Methods:

  • Prospective cohort study of 152 PSP patients.
  • Clinical interviews, examinations, and medical record reviews within the first 2 years.

Main Results:

  • Identified a cluster of typical PSP symptoms.
  • Found a subgroup (20%) with predominant frontal presentation.
  • This frontal subgroup showed similar survival to typical PSP patients.

Conclusions:

  • A subset of PSP patients exhibits an initial frontal presentation.
  • These patients evolve into typical PSP over time.
  • Frontal presentation does not impact PSP prognosis.
