However, I have been experiencing hallucinations, I have explored DBS with the Movement Disorders Clinic at Barnes Hospital in St. Louis but the sugeon is reluctant t o proceed because of my present health status. I am 74 years old and have had asthma since the age off 25. I have had chronic sinusitis since I was a child. I have stage 3 kidney failure. I had a criical bout of pneumonia in and my heart was compro-mised as well as my lungs. Are there any9 more effective drugs available? What treatment do you suggest?
