Personalizing Treatment for Clinical Depression with Brain Stimulation

Clinical trial finds deep magnetic stimulation is helpful in treating major depressive disorder

Major depressive disorder (MDD), or clinical depression, is a mental health condition characterized by persistent sadness, hopelessness, and a lack of interest or pleasure in once enjoyable activities. These symptoms can interfere with daily life, affecting relationships, work, and overall quality of life. Other common symptoms of MDD may include changes in appetite or sleep patterns, difficulty concentrating, low energy or fatigue, and thoughts of self-harm or suicide.

MDD is a common mental health condition, affecting approximately 7% of adults in the United States annually. It is caused by genetic, environmental, and psychological factors and is often treated with medication, psychotherapy, and lifestyle changes. If you or someone you know is experiencing symptoms of MDD, it is essential to seek help from a mental health professional.

Traditional treatments such as antidepressants may not work for everyone. However, a novel intervention called Deep transcranial magnetic stimulation (Deep TMS) has shown promise in treating MDD by targeting specific brain areas. While the lateral prefrontal cortex (LPFC) has been the primary target for Deep TMS, recent data suggest that targeting the medial prefrontal cortex (MPFC) using the H7 coil may yield better outcomes.

Clinical Trial

A prospective, multicenter, randomized study was conducted with 169 patients with MDD who had failed to respond to antidepressants. Patients were randomly assigned to receive 24 Deep TMS sessions over six weeks using either the H1 or the H7 coil. The primary efficacy endpoint was the change in Hamilton Depression Rating Scale scores from baseline to week six.

The study found that the H1 and H7 coils had similar clinical efficacy and safety profiles. EEG measurements taken during the first treatment session correlated with clinical outcomes in a coil-specific manner, suggesting that different patients may benefit from LPFC versus MPFC stimulation targets.

Conclusion

This study offers a potential treatment option for MDD patients who have failed to respond to antidepressants, using the H7 coil for Deep TMS. Furthermore, identifying clinical markers that can distinguish between patients who may benefit from LPFC versus MPFC stimulation targets is a promising step toward personalizing treatment for MDD. However, further validation studies are needed to confirm these findings.
