Accelerated rTMS: A Potential Treatment to Alleviate Refractory Depression.

Area of Science:

• Neuroscience
• Psychiatry
• Neuromodulation

Background:

• Repetitive transcranial magnetic stimulation (rTMS) is an established psychiatric treatment for major depressive disorder (MDD).
• Current rTMS protocols offer modest effect sizes, necessitating strategies to enhance treatment efficacy for resistant depression.
• Personalization and treatment intensification are emerging approaches to improve outcomes in refractory depression.

Purpose of the Study:

• To compare the clinical efficacy of accelerated high-frequency rTMS (arTMS) versus accelerated intermittent theta burst stimulation (aiTBS) in patients with refractory depression.
• To evaluate the potential of accelerated neuromodulation techniques to shorten the time to clinical response in major depressive disorder.

Main Methods:

• Retrospective comparison of accelerated high-frequency rTMS (arTMS) and accelerated intermittent theta burst stimulation (aiTBS) protocols.
• Study population included patients with refractory major depressive disorder undergoing accelerated stimulation.

Main Results:

• No significant difference in clinical efficacy was observed between arTMS and aiTBS protocols.
• Accelerated stimulation approaches demonstrated potential in reducing the treatment duration from a depressed state to a response state.
• The study observed a potential time gain in achieving a recovered state for patients undergoing accelerated rTMS protocols.

Conclusions:

• Accelerated rTMS and aiTBS are viable options for treating refractory depression, offering comparable clinical efficacy.
• These accelerated protocols show promise in shortening the time to achieve a therapeutic response in major depressive disorder.
• Reducing the time to recovery is a significant benefit for patients experiencing treatment-resistant depression.
