Comparing the accuracy of the DCTclock and Montreal Cognitive Assessment to detect cognitive impairment and cerebral amyloid status in older adults

Sensitive and non‐invasive methods of screening for early‐stage Alzheimer’s disease (AD) are urgently needed. Digital assessment tools have the potential to improve the efficiency of cognitive screening for older adults in both clinical and research settings. The Linus Health DCTclock uses a digital pen to capture traditional clock drawing test performance and advanced analytics to evaluate the drawing process for indicators of cognitive difficulty.
