Can Ketamine Infusion Therapy relieve Depression, Bipolar or PTSD?

About 70% of patients with treatment-resistant depression (including patients who suffer from bipolar disorder) experience rapid improvements in their condition after receiving a low-dose ketamine infusion.  Similar success rates have been seen in returning combat veterans suffering from PTSD.  In recent studies, the patients that received the Ketamine Infusion Therapy had extremely severe cases, which have existed for years or even decades, and which have not responded to any other treatments. Many remained on the verge of suicide for years, many had actually attempted suicide, and all had endured an unproductive life. Studies show that Ketamine Infusion Therapy has worked positively on 70% of the patients who have used this therapy.  Before ketamine therapy, there was virtually no way to substantially improve the condition of patients like these. It’s important to keep in mind, however, that the degree of relief can vary among patients.  Some sufferers get only partial relief, some do not get relief until a second or third infusion.
