A diagnostic aid system, method, and computer program are disclosed.These are devised for assessment of a brain status of a subject, wherein said brain status comprises a neurodevelopmental disorder or a brain disease induced brain dysfunction, wherein said system is adapted to determine an occurrence and/or stage of said neurodevelopmental order or brain disease induced brain dysfunction in said subject. An apparatus is provided that is adapted to determine said occurrence and/or stage of said neurodevelopmental disorder or brain disease induced brain dysfunction in said subject from speech of said subject, said apparatus comprising units that are operatively connected to each other. The apparatus comprises a unit for registering said speech of said subject over a period of time a processing unit devised for analyzing said registered speech and configured to determine a plurality of individual pause time components of said registered speech and determine a statistical distribution of said plurality of individual pause time components and wherein said processing unit is adapted to determine said occurrence and/or stage of said brain disease induced brain dysfunction from said statistical distribution.
