The Amen Clinics were established by Dr. Daniel Amen MD, a psychiatrist who has pioneered the use of SPECT imaging to understand brain function. The most active areas of brain and body will be using the most oxygen. SPECT is a nuclear medicine technique in which the blood is labelled briefly with a radioactive substance, allowing imaging of the areas of brain and/or body that are the most active. He has accumulated over 100,000 SPECT images and correlated them with the patients clinical situation. He was able to show that diagnoses such as depression, anxiety, dementia, and addiction were actually more complex, with a number of subtypes defined by different appearance on the SPECT scan. This opened up the possibility of more tailored treatments and therapies. The Amen Clinic website has a wealth of information (free) and we have included a link to this site here. We have been affiliated with the Amen Clinics for over 6 years and have found this approach helpful to our patients as they strengthen and restore the health of their brains.
