Abstract
A method of determining whether an individual has Attention Deficit Hyperactivity Disorder (ADHD) comprising: sampling the peripheral skin temperature of a human subject during a predetermined time interval when the subject is in an inactive state to provide a sampled peripheral skin temperature signal containing noise: modulating said sampled peripheral skin temperature signal containing noise with a known reference signal to produce a modulated signal; inputting said modulated signal and said known reference signal to a lock-in amplifier to produce a sampled peripheral skin temperature signal free of said noise; and analyzing the sampled peripheral skin temperature signal for a pre-selected parameter to determine whether said predetermined parameter has a value indicative of ADHD.
