This study identifies a familial form of progressive supranuclear palsy (PSP) in three relatives. Neuropathological findings confirmed PSP, suggesting a genetic basis for this rare neurological disorder.

Area of Science:

  • Neurology
  • Genetics
  • Neuroscience

Background:

  • Progressive supranuclear palsy (PSP) is a rare neurodegenerative disease.
  • Characterized by extrapyramidal symptoms and cognitive decline.
  • Typically sporadic, but familial cases are infrequently reported.

Observation:

  • Three family members presented with a progressive extrapyramidal syndrome and dementia.
  • Onset occurred in the seventh decade of life.
  • Clinical presentation mimicked typical progressive supranuclear palsy (PSP).

Findings:

  • Neuropathological examination of one affected individual confirmed the diagnosis of PSP.
  • The family's clinical and pathological data strongly suggest a hereditary form of PSP.
  • Review of literature supports the existence of familial PSP.

Implications:

  • This case provides further evidence for genetic factors contributing to PSP.
  • Highlights the importance of considering familial inheritance in atypical or early-onset PSP cases.
  • May aid in understanding the genetic underpinnings and developing targeted therapies for PSP.
