Mild Hyperbarics for Impaired Brain Function
SPECT imaging

SPECT stands for Single Photon Emission Computed Tomography. A scan is performed by injecting the patient with a radioactive substance that travels through the brain and distributes itself according to the circulatory system. 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 helped us by identifying the parts of the brain that are dormant due to a lack of oxygen.


Each patient was given a series of 10 hyperbaric treatments: one hour per day for five consecutive days for two weeks. To objectively test the effects of the hyperbaric sessions, SPECT scans were taken of each patient's brain before and after the series of treatments.



Every one of the patients who participated in the study showed improvement after only 10 treatments. Reporting fewer problems with short term memory, balance, headaches, and other symptoms of poor circulation in the brain. The SPECT scans objectively confirmed an increase in blood flow and oxygen to effected areas of the brain such as the temporal lobe, the part of the brain where short term memory is located. The improvements in the temporal lobe seen in the SPECT scans were verified when the patient regained his short term memory.


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. This study and additional research will add to our 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.
