SPECT brain scans by Dr. Gunner Heuser, M.D. showing improvement in brain function after 10 hyperbaric treatments; one hour per day for five consective days for two weeks.  SPECT brain scans were taken of each patient's brain before and after the series of treatments.
The benefits of treating toxic exposure patients with Hyperbaric Therapy appear to be very positive.  Initial results indicate that Hyperbaric Therapy has a demonstrable and positive effect on some symptoms such as short-term memory loss and balance.  The study by Dr. Gunnar Heuser, M.D. and additional research will add to the understanding of the exciting possibilities of Hyperbaric Therapy.
"We are happy to say our patients subjectively improved but the SPECT scans show they also objectively improved with increased blood flow to the temporal lobe and other areas of the brain."

SPECT Imaging:
 
"SPECT" stands for Single Photon Emission Computed Tomography.  A scan is performed by injecting the patient with a radioactive substance that travels to the brain and distributes itself according to the efficacy of the circulatory system within the brain.  The patient's brain is then scanned and a computer creates a three dimensional color image that illustrates the blood flow into all areas of the brain.  SPECT imaging helps to identify the parts of the brain that are not functioning due to a lack of oxygen.  On the images below a normal, healthy adult brain  with adequate blood flow is represented by the yellow areas of the scan.  Green is indicative of less blood flow or less oxygen.  Blue and voilet represent significantly reduced blood flow in the brain.
