Alpha-Stim cranial electrotherapy stimulation (CES) for anxiety treatment: outcomes in a United Kingdom (UK) primary care practice

Abstract

Background: Anxiety disorders are the most common mental disorders, typically treated with psychotherapy and medication. These treatments are not suitable for, acceptable to, or effective for everyone. Alpha-Stim AID is a Cranial Electrotherapy Stimulation (CES) treatment with evidence of effectiveness in treating anxiety disorders. Objective: The aim of this paper is to present outcomes on anxiety, depression, and quality of life of Alpha-Stim use in primary care patients in the United Kingdom’s (UK) National Health Service (NHS) who reported symptoms of anxiety. Methods: Open label patient cohort design. Self-report measures: PHQ-9 (depression), GAD-7 (anxiety) and EQ-5D-5L (health related quality of life). Twenty-three patients with symptoms of anxiety completed a six-week course of Alpha-Stim intervention. Results: Reliable improvement and remission rates respectively were 60.9% and 17.4% for the GAD-7; 42.9% and 22.7% for the PHQ-9. Significant improvement and medium/large effect sizes (n2 = 0.59 and 0.56 respectively). EQ-5D-5L results showed significant improvements in quality of life. Perceived quality of life doubled with an improvement of 0.36 on the health index score, this intervention adds 3.64 Quality Adjusted Life Years (QALYs). Limitations: The study was not an RCT, there was no control group. Conclusions: Alpha-Stim AID CES can be delivered through a UK primary care practice, and can have a significant impact on symptoms of anxiety and depression, and improve quality of life in primary care patients with anxiety symptoms. Further feasibility studies in primary care and sufficiently powered RCT are required.
