Abstract

Objective: To evaluate the possible biological aspects of ‘unexplained physical symptoms’, this study examined serotonergic and noradrenergic monoamino acids in somatoform disorders and/or depression. Methods: Blood samples of 150 subjects from 4 groups (somatization syndrome; depression; depression and somatization; controls) were analyzed for amino acids contributing to the serotonergic and noradrenergic system and peripheral muscle energy balance (tryptophan, valine, leucine, isoleucine, phenylalanine and tyrosine). Results: Tryptophan, branched chain amino acids and other serotonergic amino acids were decreased in patients with somatoform symptoms, even when no depression was present. Conclusions: We conclude that serotonergic amino acids are biological correlates of multiple unexplained symptoms. Ways of action do not only involve brain mechanisms, but also energy metabolism in peripheral muscles.
