Method for evaluating a risk of neurodevelopmental disorder with a child

Method for evaluating a risk of neurodevelopmental disorder with a child, the method comprising the steps of:

• providing a machine comprising a display screen, an eye-tracking device, a controller configured for displaying information on the display screen and for reading and recording eye position data from the eye-tracking device;
• having the child passing a first test in the course of a first time period, the first test comprising, in sequence:
• having the child looking at the display screen and directing the eye-tracking device towards at least one eye of said child,
• displaying first information on the display screen and meanwhile reading and recording eye position data from the eye-tracking device, thereby obtaining first recorded movements of the at least one eye of the child,
• comparing data from the first recorded movement of the at least one eye of the child with first pre-recorded reference data and calculating a first score in function of said comparison;
• having the child passing at least a second test in the course of a second time period, the second test comprising, in sequence:
• having the child looking at the display screen and directing the eye-tracking device towards at least one eye of said child,
• displaying second information on the display screen and meanwhile reading and recording eye position data from the eye-tracking device, thereby obtaining second recorded movements of the at least one eye of the child,
• comparing data from the second recorded movement of the at least one eye of the child with second pre-recorded reference data and calculating a second score in function of said comparison;
• characterized in that
• the second time period starts at least 24 hours later than the end of first time period,
• the second information is different from the first information, and
• the controller calculates and delivers a composite score which is a function of at least the first score and the second score.
