Abstract:
1. A method of determining whether a subject has Attention Deficit Hyperactivity Disorder, comprising: sampling the peripheral skin temperature of the subject 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 maximum frequency f aggregating the magnitude ranges for one or more of the windows to produce an aggregate magnitude range value which is indicative of whether or not the subject has ADHD; wherein after said sampling, temperature data sampled during a noise event is eliminated through manual or automatic means.
