The positive response of children with ADHD to treatment with stimulant medications, which have dopaminergic and noradrenergic agonist activity, suggests catecholamine abnormalities in ADHD (Cantwell, 1996; Pliszka et al., 1996). As direct measurement of catecholamine concentrations in the brain is not possible, evidence for differences in ADHD has been sought from measurements of catecholamine metabolite concentrations in cerebrospinal fluid (CSF), blood and urine. The results of these studies are inconsistent (Cantwell, 1996; Mason, 1984; Pliszka et al., 1996; Raskin et al., 1984; Weizman et al., 1990), thus the precise nature of catecholamine anomalies in ADHD remains unknown and several different theories have been suggested.
