Dr. Paolo Cassano - Shining Light on Cognitive Health

Cutting Edge Health: Preventing Cognitive Decline

Feb 17 2024 • 40 mins

Dr. Paolo Cassano, an expert in photobiomodulation, discusses its potential in preventing cognitive decline. He traces his journey from a focus on international psychiatry to pioneering research in using light therapy for brain disorders.

Photobiomodulation involves non-invasive transcranial exposure to specific wavelengths of light, particularly near-infrared light. Dr. Cassano's "aha" moment came when he observed significant improvements in patients' mental health, including reduced depression symptoms and improved cognitive function. While his current Alzheimer's study will take a few more years for conclusive results, he points out that accessible photobiomodulation devices are already available, with industry trends shifting towards more comprehensive support systems. He advises seeking reputable companies that market devices within the $1,000 range.

Dr. Cassano highlights the potential for systemic effects and discusses the exciting future of this field, especially for individuals seeking alternative treatments. The interview sheds light on an emerging therapeutic approach that offers hope in the fight against cognitive decline.
