Abstract

BACKGROUND:

Anxiety disorders are among the most prevalent mental disorders and are usually treated with medication and/or psychotherapy. When anxiety disorders are accompanied with comorbid depression, this further complicates the treatment process. Medication compliance is a common problem due to adverse side effects and new and effective treatments that have minimal side effects are needed for the treatment of anxiety and depression. This study used a randomized, double-blind, sham controlled design to examine the effectiveness of CES as a treatment for anxiety disorders and comorbid depression in a primary care setting. The study was registered at clinicaltrials.gov, NCT01533415.

METHODS:

One hundred and fifteen participants, age 18 years and over, with a primary diagnosis of an anxiety disorder were enrolled from February 2012 to December 2012 The Hamilton Rating Scale for Anxiety (HAM-A) and the Hamilton Depression Rating Scale17 (HAM-D17) were used for baseline and outcome measures at weeks one, three, and five. Response to treatment was defined as a reduction of ≥50% or more on these measures.

RESULTS:

Analysis of covariance revealed a significant difference between the active CES group and the sham CES group on anxiety (p=0.001, d=0.94) and on depression (p=0.001, d=0.78) from baseline to endpoint of study in favor of the active CES group.

CONCLUSIONS:

CES significantly decreases anxiety and comorbid depression. Subjects reported no adverse events during the study.
