Early Detection of Alzheimer's Disease and Affective Disorders by Automated Voice and Speech Analysis (PLATA)
PLATA is testing whether an algorithm can detect early signs of Alzheimer's disease by analyzing how people speak during a phone-based cognitive task. Researchers will compare speech patterns against established biological markers like CSF proteins and PET scans. This is a diagnostic research study, not a clinical drug trial — the goal is to see if voice analysis could one day replace invasive testing like lumbar punctures. Details on phase are limited.
