Patent ID: 7409373

Claim:
A method for the detection of a characteristic of a person by means of a computer which generates a report placing said person in a special category in need of treatment, said computer employing a trained artificial neural network (ANN) in which motion data are analyzed, said method comprising: measuring motion data from said person; collecting other measured data from said person, under influence of a drug; calculating the values of one or several parameters distinctive of various characteristics; feeding said parameter values to said ANN trained to recognize said various characteristics; analyzing said parameter values in said trained ANN; wherein said parameters comprise at least the variance of continuous performance task (CPT) variables, said variance of CPT variables comprising variance of latency t defined as: 1 N - 1 ⁢ ∑ i = 1 N ⁢ ( t i - t _ ) 2 where the latency t is the delay or reaction time, N being the number of samples of the complete measurement, and t _ = 1 N · ∑ i = 1 N ⁢ t i .
