Rapid repetitive syllable sounds associate with episodic memory, executive function, and working memory in cognitively healthy and subjectively impaired older adults.

ABSTRACT: Non-invasive screening tools for Alzheimer's disease (AD) risk are needed. Decline in episodic memory and subjective cognitive impairment (SCI) are both associated with elevated AD risk. We investigated associations between three cognitive domains (episodic memory, executive function, and working memory) and motor speech performance in older adults with healthy cognition (HC) or SCI. In total, 1014 community-dwelling participants (cross-sectional sample: 843 HC, mean 66.9 years, 72.8% female; 171 SCI, mean 66.3 years, 70.8% female) remotely completed cognitive tests (Paired Associates Learning and Spatial Working Memory from the Cambridge Neuropsychological Test Automated Battery) and motor speech tests (Tasmanian [TAS] Test). We evaluated whether acoustic motor speech features extracted f
