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

6. A method of diagnosing ADHD or a related disorder in a subject comprising the steps of:
-
(i) providing motion data for said subject, wherein said motion data has been collected by using a motion analysis device to record movements of said subject to produce said motion data; (ii) using a computer to perform an analysis of said motion data, wherein said analysis comprises calculating from said motion data the number of spikes in said movements, wherein said spikes are bursts in the rate of said movements by said subject exceeding a threshold amplitude of greater than 1 mm/second; and (iii) on the basis of said number, diagnosing said whether subject has ADHD or a related disorder. - View Dependent Claims (7, 8, 9)

14. A method for assessing the efficacy of a medicament for the treatment of ADHD or a related disorder in a subject diagnosed with said disorder, said method comprising:
-
(i) providing medicated motion data for said subject, wherein following administration of said medicament to said subject said medicated motion data has been collected by using a motion analysis device to record movements of said subject while medicated to produce said medicated motion data; (ii) using a computer to perform an analysis of said medicated motion data, wherein said analysis comprises calculating from said medicated motion data the power spectral density of the oscillations in said movements over a frequency range between 0.01 and 0.5 Hz; and (iii) on the basis of said spectral density, determining the effect of said medicament on said subject diagnosed with said disorder. - View Dependent Claims (15)
