DCTclock Detects Cognitive and Motor Impairment In Parkinson’s Disease and Quantifies Drawing Tremor

Ali Jannati, MD, PhD 
Director of Cognitive Science, Linus Health

Poster Number: #3176
Virtual EP — 108

Key takeaways:

  • DCTclock detects cognitive impairment in Parkinson’s disease and differentiates between varying levels of cognitive function.
  • The Oscillatory Motion (OM) metric accurately quantifies drawing tremors and aligns closely with clinician ratings.
  • DCTclock helps distinguish between PD patients needing pre-surgical cognitive workups and those with cognitive concerns, aiding clinical decision-making.

Neuropsychological Validation of a Brief Protocol for Digital Assessment of Cognition

Ali Jannati, MD, PhD 
Director of Cognitive Science, Linus Health

Poster Number: #3207
Virtual EP — 073

Key takeaways:

  • The 7-minute Digital Assessment of Cognition (DAC) achieves high accuracy in classifying cognitive status, aligning closely with a traditional 3-hour neuropsychological evaluation.
  • DAC utilizes speech-based responses and automated digital administration, enhancing efficiency while maintaining diagnostic precision.
  • With more than 90% accuracy in detecting mild cognitive impairment and dementia, DAC offers a rapid, scalable solution for remote or in-person cognitive evaluation.
