However, the advantage faded within four weeks as the placebo group caught up. The findings indicate that while iTBS may provide rapid symptom relief, a longer or modified treatment schedule may be needed to achieve lasting benefits. Researchers say further studies are required to determine the most effective long-term treatment approach.
