Abstract
Background and aimAchalasia represents a chronic motility disorder of the esophagus featuring an impaired lower esophageal sphincter relaxation and loss of esophageal peristalsis. By causing dysphagia, regurgitation, aspiration and chest pain, achalasia might tremendously affect life quality of patients. However, the impact of achalasia on the development of mood disorders including depression has largely remained unclear. The aim of this study was to evaluate the incidence of depression in achalasia patients.MethodsWe analyzed a large primary care cohort database in Germany capturing data from 7.49 million patients.ResultsA total of n = 1,057 patients with achalasia diagnosed between January 2005 and December 2018 were matched to a cohort of n = 3,171 patients without achalasia controlling for age, sex, physician, index year, and the Charlson comorbidity index. Interestingly, while the frequency of depression prior to the diagnosis of achalasia was comparable in both groups, new diagnoses of depression were significantly higher within one year after the diagnosis of achalasia compared to the control group, suggesting a direct and previously unrecognized association between achalasia and depression.ConclusionOur data suggest that the clinical management of patients with achalasia should include a careful and structured work-up for mood disorders in order to improve long-term quality of life in these patients.
Highlights
The first description of achalasia goes back to Sir Thomas Willis in 1674

Summary
Achalasia is defined as a chronic disorder of esophageal motility characterized by an impaired lower esophageal sphincter (LES) relaxation and the loss of esophageal peristalsis [1]. Different studies estimate the incidence at 1.6 per 100,000 population and the prevalence at 10.8 per 100,000 population. Males and females are affected, most patients are diagnosed between 30 to 60 years of age [2, 3]. Achalasia represents a chronic motility disorder of the esophagus featuring an impaired lower esophageal sphincter relaxation and loss of esophageal peristalsis. Regurgitation, aspiration and chest pain, achalasia might tremendously affect life quality of patients. The impact of achalasia on the development of mood disorders including depression has largely remained unclear. The aim of this study was to evaluate the incidence of depression in achalasia patients
