CBR Seminar Series: Stacy Andersen, 6/30/25

Join us on June 30th to attend Stacy Andersen's CBR Seminar Series titled "Characterizing cognitive function and resilience to Alzheimer's disease using digital technologies". One obstacle to studying cognitive aging is the inability to identify cognitive impairment and cognitive change with adequately high sensitivity and specificity. Brain changes related to aging or to neurodegenerative diseases are known to begin years before substantial changes emerge on cognitive testing. The integration of digital technologies allows for the capture of high-precision data from spoken and written responses to cognitive test items that may capture changes in cognitive function earlier than traditional summary test scores. This talk will present findings from digital pen data showing differential patterns of motor and cognitive slowing on a coding test and preclinical differences in cognitive processing on a clock drawing test. It will also present preliminary data on lexical and temporal features extracted from digital voice recordings of verbal responses. These findings will demonstrate the clinical value of digital cognitive biomarkers across the spectrum from cognitive impairment to cognitive superaging.
