1. A method of diagnosing ADHD or a related disorder in a subject comprising the steps of:
- (i) using a motion analysis device to record movements and produce motion data of said subject and transmitting said motion data to a computer for analysis;
(ii) receiving the results of said analysis, wherein said analysis comprises calculating from said motion data the power spectral density of the oscillations in said movements; and
(iii) on the basis of said spectral density, diagnosing whether said subject has ADHD or a related disorder, wherein said spectral density is calculated over a frequency range between 0.01 and 0.5 Hz.
