Abstract
Several lines of evidence suggest that catechol-O-methyltransferase (COMT) may be associated with treatment response in depression. We conducted a study on 119 patients with treatment-refractory depression admitted consecutively for electroconvulsive therapy (ECT). The COMT high/high genotype leads to a higher enzyme activity and thus lowers dopaminergic activity in the prefrontal cortex. In the present sample, those homozygous to high-active allele of COMT responded significantly more frequently to ECT.
