Technique for diagnosing attention deficit hyperactivity disorder

Abstract

A method for determining a threshold value of a parameter used to determine whether an individual has Attention Deficit Hyperactivity Disorder (ADHD) comprising: providing a group of individuals a segment of which is known to have ADHD and a segment of which is known to be normal and not have ADHD; testing each individual in the group by sampling the peripheral skin temperature of the individual during a pre-determined time interval when the subject is in an inactive state to provide sampled peripheral skin temperature data, and analyzing the sampled peripheral skin data to produce a parameter value for that individual; and processing the individual parameter values for all of the members of the group to determine a threshold parameter value which is acceptable for determining whether or not an individual has ADHD when tested by said testing procedure.

1 . A method of determining whether an individual has a disorder characterized by inattention, hyperactivity, and impulsivity, comprising: 
 sampling the peripheral skin temperature of an individual during a pre-determined time interval when the subject is in an inactive state to provide sampled peripheral skin temperature data;    dividing the data into a series of windows of equal time intervals across the pre-determined time interval;    for each window applying a fast Fourier Transform algorithm (FFT) to produce a data set of FFT magnitudes and determining a range of FFT magnitude variation, which is the difference between the FFT magnitude at a frequency f max  and the FFT magnitude at the minimum frequency; and    aggregating the magnitude ranges for one of or less than all of the windows to produce an aggregate magnitude range value which is indicative of whether or not the individual has said disorder.
