Researchers have demonstrated that brain stimulation at a 40 Hz frequency can protect brain tissue from the harmful effects of chemotherapy drugs such as cisplatin and methotrexate. This treatment, involving light and sound exposure, not only protected brain tissue but also helped prevent memory loss and cognitive function decline in animal models. Remarkably, the positive effects of the 40 Hz frequency persisted for four months, emphasizing its potential in shielding patients from the toxic side effects of cancer treatments. Further clinical studies are needed to confirm its effectiveness in humans. For more detailed information, please visit https://news.mit.edu/2024/noninvasive-treatment-chemo-brain-0306
