Dear Dr. Grief, I am a 69 year old man and was diagnosed as bipolar when I was 24 years old. I have been under the care of pschiatrists and psychologists since that time. I have never had to be hospitalized for this condition. I have co-morbid diagnoses of ADD and mild obsessive compulsive disorder. Would I be a candidate for ketamine infusion treatment? Thank you for any assistance you can provide me. I now live on the severely depressed end of the scale. No manic symptoms in years. I would give anything to know just a short period of normalcy or dare I ask, happiness just one time before the depression kills me. Thank You, Sam Barnes, Tallahassee, FL
