SYSTEM AND METHODS FOR ASSESSMENT OF THE AGING BRAIN AND ITS BRAIN DISEASE INDUCED BRAIN DYSFUNCTIONS BY SPEECH ANALYSIS

摘要

A system and method for assessment of a brain status of a subject are disclosed. The brain status comprises a brain disease induced brain dysfunction. An occurrence and/or stage of the brain disease induced brain dysfunction in the subject is determined. The system comprises an apparatus that is adapted to determine the occurrence and/or stage of the brain disease induced brain dysfunction in the subject from random speech of the subject. The apparatus (200) comprises units that are operatively connected to each other, which comprises a unit (205) for registering the speech of the subject over a period of time; a unit (206) devised for analyzing the registered speech and configured to determine a pause component of the speech; and a unit that is adapted to determine the occurrence and/or stage of the brain disease induced brain dysfunction from the pause component, wherein said pause component is an accumulated pause time of a total time of said speech correlated to said occurrence and/or stage of said brain dysfunction.
