Area of Science:

  • Neuroscience
  • Ophthalmology
  • Sports Medicine

Background:

  • The King-Devick (KD) test is a sensitive measure for concussion diagnosis.
  • Increased test time in the KD test correlates with concussion severity.
  • Eye tracking reveals prolonged inter-saccadic intervals (ISI) during KD testing in concussed individuals, associated with longer test times.

Purpose of the Study:

  • To investigate the relationship between prolonged ISI during KD testing and cognitive performance in individuals with persistent post-concussion symptoms.
  • To explore ISI prolongation as a potential indicator of cognitive dysfunction after concussion.

Main Methods:

  • Retrospective analysis of 14 participants with prior neuropsychological assessments and KD testing with eye tracking.
  • Measurement of KD test times and ISI.
  • Correlation analysis between ISI prolongation and cognitive test scores (processing speed, attention, working memory, executive function).

Main Results:

  • Participants exhibited prolonged KD test times and median ISI compared to normative values.
  • Greater ISI prolongation was significantly associated with lower scores in processing speed, attention/working memory, and executive function.
  • Specific cognitive domains affected include WAIS-IV Coding, Trails Making A, Digit Span (Forward, Backward, Total), and Stroop Color Word Interference.

Conclusions:

  • This pilot study suggests a preliminary association between prolonged ISI and cognitive dysfunction in individuals with persistent post-concussion symptoms.
  • ISI prolongation during KD testing may serve as a potential objective biomarker for assessing cognitive impairment after concussion.
  • Further research is warranted to validate these findings and explore clinical applications.
