got results from Columbia's spect scan. It's identical to last years. This frustrates me because I feel the same and with almost a year of treatment, there has been no change. IV for almost 8 mos. rocephin and zithromax. "Moderate global hypoperfusion with heteregenity." Same - slowness in circulation in the brain. "It may be seen in encephilitis, vasculitis, some medications and lyme disease". Any suggestions on what to think? All is appreciated.
