Status Recruiting

Clinical Trial Summary

This is a randomized double-blind sham-controlled crossover study; the interventions are high-frequency rTMS stimulation on left DLPFC and sham control. The study population is the patient with somatic symptom disorder. The primary outcomes are somatic distress and health anxiety.

Clinical Trial Description

Somatic symptom disorder (SSD) is a psychiatric diagnosis featured with somatic distress and health anxiety. It is overlapped with functional disorders. Whether it has effective treatment is a clinically important issue. Current evidence indicates that pharmacotherapy and psychotherapy are both helpful for SSD. Among other treatment options, repetitive transcranial magnetic stimulation (rTMS) is attached important in psychiatric field; it can cause activation or inhibition of specific brain regions via magnetic stimulation. Previous studies have disclosed that rTMS is helpful for depression, obsessive-compulsive disorder, post-stroke rehabilitation, etc. Regarding functional disorders, fibromyalgia has been found to be benefited from rTMS; the effective approaches include giving high-frequency stimulation on left M1 and dorsolateral prefrontal cortex (DLPFC). Chronic tinnitus was also found to have response to rTMS. SSD and fibromyalgia are highly overlapped; SSD and depression are often comorbid. Therefore, SSD may also be benefited from left DLPFC high-frequency stimulation. Our previous study revealed that dysfunction of anterior cingulate cortex (ACC) is associated with persistent interference of the somatic discomforts; stimulation on DLPFC can cause ACC activation. This study program was designed based on the above information. It is a randomized double-blind sham-controlled crossover study; the interventions are high-frequency rTMS stimulation on left DLPFC and sham control. The primary outcomes are somatic distress and health anxiety. There is not study about rTMS on SSD in literature; the investigators expect this study to be able to provide more understanding on this field. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
