Depression: The Hidden Problem in Fabry Disease

Abstract

Fabry disease (FD) is an X-linked disorder of glycosphingolipids caused by mutations of the GLA gene. The classical form presents with neuropathic pain and gastrointestinal complaints since childhood or adolescence and progressing into adulthood with ischemic stroke, cardiac dysfunction, and chronic kidney disease. Depression seems to be a frequent complication of FD but its frequently underdiagnosed and undertreated. Comorbid depression in different chronic diseases has been associated with an overall increase in disease burden and medical costs, impairment in activities of daily living, and impact on self-care and treatment adherence. In addition, a clear association between pain and depression has been observed in FD patients and appears to have an unequivocal neurobiological matrix. The aim of this review is to provide an overview of the literature on depression in patients with FD and to highlight some of the emerging issues on this topic. Further research to improve detection and to develop effective treatments for depression in this population is promptly needed.
