Effectiveness of antidepressant repetitive transcranial magnetic stimulation in a patient with refractory psychogenic dysphagia: A case report and review of literature.

BACKGROUND

Dysphagia is a common condition in older as well as young patients, and a variety of treatments have been reported depending on the cause. However, clinicians are challenged when the cause is unclear. This is the case with psychogenic dysphagia, which has typically been treated with supportive psychotherapy, medication, swallowing exercise, and dysphagia rehabilitation therapy. Here, we aimed to relieve the symptoms of a patient with refractory psychogenic dysphagia, who was unresponsive to conventional swallowing therapy, with repetitive transcranial magnetic stimulation (rTMS).

CASE SUMMARY: A relatively calm-looking 35-year-old female patient presented with a 2-year history of dysphagia. She showed little improvement with conventional swallowing treatments over the past 2 years. She was relatively compliant with in-hospital dysphagia therapy, but uncooperative with home exercise and medication. In particular, since she was resistant to drug treatment, we had to take a different approach than the treatment she had been receiving for the past 2 years. After much deliberation, we decided to initiate antidepressant rTMS treatment with her consent (IRB No. 2023-05-021). Antidepressant rTMS treatment was performed twice weekly for a total of 20 sessions over 10 wk. The results showed improvement in subjective symptoms and video fluoroscopic swallowing study findings. To the best of our knowledge, this is the first report of symptomatic improvement using antidepressant rTMS protocol for refractory psychogenic dysphagia.

CONCLUSION

This case demonstrates that rTMS with antidepressant protocol can be used to improve swallowing in patients with refractory psychogenic dysphagia.
