The efficacy of the therapies mainly focuses on the whole holistic approach. There isn't the hard data that's available for the drug therapies, but it's definitely showing promising results in clinical reports and data.
The most rigorous data comes from the study by Dr. Harvey Moldofsky and Dr. Richardson from OSI London. They followed 14 years' worth of veterans in sleep studies. They can predict through sleep studies who is going to be more likely to develop PTSD and show signs of PTSD.
Everyone who goes through our program has a rigorous sleep study as well.
