Validation of the ki:e SB‐C a Novel Digital Speech Biomarker for Cognition in a Dutch Memory Clinic Population

Progressive cognitive decline is the cardinal behavioral symptom in most dementia‐causing diseases such as Alzheimer’s disease. Whereas classic neuropsychological tests often have excellent psychometric properties to measure cognitive decline in dementia, there are scenarios in which they are less suitable. Speech‐based digital biomarkers can be deployed remotely and extracted in a highly automated fashion allowing solutions to scale. We present the validation of a novel digital Speech Biomarker for Cognition (SB‐C) in a Dutch memory clinic population containing patients with Mild Cognitive Impairment (MCI) and age‐ as well as education‐matched participants with Subjective Cognitive Decline (SCD).
