Abstract
A method of determining threshold values, subsequently used to determine whether an individual has Attention Deficit Hyperactivity Disorder (ADHD) comprising: providing a group of subjects, a segment of which is known to have ADHD and a segment is known to not have ADHD; and testing each subject in the group by: (a) sampling the peripheral skin temperature of left and right like extremities during a predetermined time interval when the subject is in a sensory deprived state to provide respective left and right sampled peripheral skin temperature data; (b) processing the sampled peripheral skin temperature data, including filtering, differentiation, and conversion to the frequency domain to derive spectral signatures having magnitude values; and (c) final processing of spectral signatures for all of the subjects of the group to determine threshold values which are complimentarily effective for determining whether or not an individual has ADHD when tested by the testing method.
