There are studies, studies and studies.... fact everywhere, nothing hidden, but still no cure documented. Even Dr. Shapiro has never claimed EMDR cures PTSD, because she knows it doesn't. EMDR helps a person process their trauma, which as a result reduces symptoms, which combined with exposure therapy can get a person back into a fairly normal life.... maybe slightly medicated, maybe not, though able to work for some, not for others. Why? Because it doesn't cure the chemical imbalance that has taken effect within the brain. They are trying to fix this with medications, being they find the missing chemicals or the chemicals that are too high, and replace them or attempt to reduce them.... still though, no cure yet.
