Multimodal Dementia Screening from Brain Magnetic Resonance Imaging and Conversational Speech.

Early detection of Alzheimer's dementia is crucial for effective symptomatic treatment. Herein, we explore the opportunities of dementia screening based on automatically derived biomarkers from Magnetic Resonance Imaging (MRI) and spoken communication. In particular, we compare the screening performance of unimodal MRI-based or speech-based markers with their multimodal counterparts.
