DementiaBank: An open access language database to understand the progression of dementia

Abstract We propose the expansion and development of the open-access DementiaBank database of multimedia interactions for the study of cognitive-communication impairments in aging and Alzheimer’s disease and related dementias. This work will rely on advances in data collection, transcription, analysis, sharing, and web delivery achieved in the context of the overall TalkBank Project. We will deploy and extend the growing assets of TalkBank and DementiaBank to answer critical questions regarding the diagnosis, classification, and longitudinal tracking of language in dementia. The overall goal of this work is to support the development of cognitive-linguistic outcome measures and treatments that will improve the evaluation and effectiveness of early diagnosis, and to identify those at risk for dementia. To reach that goal, we must solidify methods for data analysis and machine learning training, Collaborative Commentary, automatic speech recognition, and algorithm evaluation benchmarks. We will also focus on the expansion of dissemination methods to ensure the DementiaBank tools and resources are meeting the needs of researchers and clinicians.
