Embodiment Construction

[0058] According to the present invention there is provided a method for assessing the risk of a neurodevelopmental disorder in a child.

[0059] The method first comprises the steps of: providing a machine comprising a display screen 5, an eye tracking device 10 and a controller 15 configured to display information on the display screen 5 and to read and record eye position data from the eye tracking device 10 .

[0060]The machine may be, for example, a portable personal computer or tablet computer to which an eye-tracking device is connected. Various commercially available eye tracking devices can be used, such as Tobii Technology's Eye Tracker4C model or SensoMotoric Instruments' RED-m or ISCAN Inc.'s RK- 464 model or Eye Tech's TM5 Mini. Such eye-tracking devices come with suitable control software which, once installed and running, enables the controller 15 (usually the computer itself) to read and record eye position data from the eye-tracking device 10 . The machine...

Abstract

A method is provided which performs at least two different tests on a given child (20) at respectively at least two different ages of said child. In the course of a first test, a first information isdisplayed to the child and meanwhile a controller (15) acquires first data about eye movements of the child via an eye-tracking device (10) and determines a first score by comparison of said first data with first pre-recorded reference data. The same is performed in the course of a second test at a second age of said child with second information which is different from the first information, hence yielding a second score. A composite score is then calculated for said child in function of at least the first and the second scores. This composite score is a more reliable indication of a risk ofneurodevelopmental disorder than indicators obtained with known methods.

Description

technical field [0001] The present invention relates to methods and devices for assessing the risk of a child suffering from a neurodevelopmental disorder, in particular an autism spectrum disorder (ASD). Background technique [0002] International Patent Publication WO 2015 / 057321 discloses a method close to the technical field of the present invention but substantially different. [0003] According to this known method, first eye movement data of the child are collected during a first session, during which the child is shown a first visual stimulus, and second eye movement data of the same child are collected during a second session , during which the child is shown a second visual stimulus. The first eye movement data was then compared with the second eye movement data to identify changes in the children's fixation to the two visual stimuli. Gaze decline has been described as a marker of a child's developmental, cognitive, social, or intellectual disability or ability. ...
