Abstract

The present invention is an innovative system and method for passive diagnosis of dementias. The disclosed invention enables early diagnosis of and assessments of the efficacy of medications for neural disorders which are characterized by progressive linguistic decline and circadian speech-rhythm disturbances. Clinical and psychometric indicators of dementias are automatically identified by longitudinal statistical measurements and track the nature of language change and/or patient audio features change using mathematical methods. According to embodiments of the present invention the disclosed system and method include multi-layer processing units wherein initial processing of the recorded audio data is processed in a local unit. Processed and required raw data is also transferred to a central unit which performs in-depth analysis of the audio data. The combined analysis enables the identification of the frequencies and nature of temporary relapses of linguistic decline, and provides essential data for diagnosing early stages of different types of dementias.
