Area of Science:

  • Neurology
  • Geriatrics
  • Cognitive Science

Background:

  • Dementia diagnosis relies on cognitive assessments.
  • Early detection of Alzheimer's disease (AD) and cerebrovascular dementia (CVD) is crucial for timely intervention.
  • Traditional screening tools may have limitations in accessibility or specificity.

Purpose of the Study:

  • To develop and validate a modified, computer-based trail-making test (TMT) for dementia screening.
  • To compare the performance of the digital TMT with the Mini-Mental State Examination (MMSE).
  • To assess the digital TMT's utility in identifying cognitive deficits associated with AD and CVD.

Main Methods:

  • A modified TMT was created using a PC and touch-panel display.
  • Participants were instructed to touch numbers 1 through 36 sequentially as quickly as possible.
  • The study included 134 dementia patients; 62 completed the digital TMT and MMSE.

Main Results:

  • A significant negative correlation (r = -0.534) was found between digital TMT completion time and MMSE scores.
  • Shorter TMT completion times were associated with better cognitive performance as measured by MMSE.
  • The digital TMT demonstrated potential as an indicator of focal frontal lobe dysfunction.

Conclusions:

  • The PC-based TMT is a viable tool for early screening of dementia, including Alzheimer's disease.
  • This digital test offers a potentially sensitive and accessible method for cognitive assessment.
  • The TMT may aid in differentiating cognitive impairments and identifying early-stage neurological changes.
