This review details advances in diagnosing progressive supranuclear palsy (PSP), a common neurodegenerative disorder. Understanding tau mutations and neuroinflammation aids in identifying PSP risk factors and improving diagnostic accuracy.

Area of Science:

  • Neuroscience
  • Neurology

Background:

  • Progressive supranuclear palsy (PSP) is the most common atypical parkinsonian neurodegenerative disorder.
  • Diagnostic challenges have historically limited accurate and timely PSP diagnosis.

Purpose of the Study:

  • To review recent advances in understanding PSP diagnosis.
  • To elucidate the role of potential risk factors in PSP development.

Main Methods:

  • Review of current literature on PSP diagnosis and risk factors.
  • Detailed explanation of neurodegenerative mechanisms relevant to PSP.

Main Results:

  • Improved understanding of diagnostic challenges has enhanced PSP diagnostic accuracy.
  • Identification of tau mutations, mitochondrial dysfunction, oxidative injury, and inflammation as potential PSP risk factors.

Conclusions:

  • Advances in understanding PSP pathogenesis are improving diagnostic capabilities.
  • A comprehensive grasp of risk factors is crucial for future PSP research and therapeutic strategies.
