We have published this exchange of letters as part of our responsibility to readers to point out when a procedure may lack sufficient evidence to justify its widespread clinical use."<br /><br />The procedure in question is SPECT (single photon emission computed tomography). At issue: the use of SPECT scans as part of a psychiatric diagnostic workup by some clinics. They cast themselves as “early adopters"1 in the vanguard of developing clinical applications for an emerging technology. Their critics say it's premature, pointing out the risks of exposing patients, particularly children, to radiation, and to treatments based on shaky interpretations of scans – possibly in lieu of clinically sound treatments. Moreover, more powerful, less invasive technologies have often been supplanting SPECT in psychiatric research over the past decade.<br /><br />https://www.nimh.nih.gov/about/directors/thomas-insel/blog/2010/brain-scans-not-quite-ready-for-prime-time.shtmlGalen Breningstall, MDhttps://www.blogger.com/profile/07170864203251456228noreply@blogger.comtag:blogger.com,1999:blog-2186593343917545414.post-84524054886656362962017-12-20T22:39:51.066-08:002017-12-20T22:39:51.066-08:00Daniel Amen loves SPECT scans (Single Photon Emiss...Daniel Amen loves SPECT scans (Single Photon Emission Computed Tomography). And well he should. They have brought him fame and fortune. They have rewarded him with a chain of Amen Clinics, a presence on PBS, lucrative speaking engagements, a $4.8 million mansion overlooking the Pacific Ocean, and a line of products including books, videos and diet supplements (“nutraceuticals”). He grossed $20 million last year. Amen is a psychiatrist who charges patients $3,500 to take pretty colored SPECT pictures of their brains as an aid to the diagnosis and treatment of conditions including brain trauma, attention-deficit hyperactivity disorder (ADHD), addictions, anxiety, depression, dementia, and obesity. He even does SPECT scans as a part of marriage counseling and for general brain health checkups.<br /><br />SPECT imaging uses an injected radioisotope to measure blood flow in different areas of the brain. Amen is exposing patients to radiation and charging them big bucks because his personal experience has convinced him SPECT is useful. So far, he has failed to convince the rest of the scientific medical community...<br /><br />It’s not just me. Amen has a lot of other critics. Psychiatrist Daniel Carlat wrote “Brain Scans as Mind Readers? Don’t Believe the Hype” in Wired Magazine, describing his own evaluation by Dr. Amen. Amen told Carlat his scans showed too little activity, a pattern of angst, and a predisposition to depression (that part was a slam dunk, since in taking a medical history Amen had already elicited the information that Carlat had had a short bout with depression). He recommended a multivitamin, gingko, less snowboarding, and more tennis. An expert at UCLA later reviewed the same scans and explained that the findings are meaningless because they haven’t been validated by controlled studies to determine their diagnostic specificity. Carlat likens Amen’s spiel to the cold readings of palm readers...<br /><br />Anecdotes. He starts with an anecdote about his nephew, who had attacked a little girl for no apparent reason. Amen did a SPECT scan and found a large arachnoid cyst; after surgery, the violent behavior stopped. This is a touching story, but anecdotes are not evidence. Cysts and other brain abnormalities are frequent incidental findings on brain imaging and arachnoid cysts are often asymptomatic even when large. Even if the child’s violent behavior was due to the cyst, a SPECT scan was not necessary to find it. An MRI would have found it, with better anatomical detail and no need for radiation exposure.<br /><br />He asks,<br /><br />How could a child psychiatrist know what was going on in Andrew’s brain unless he or she actually looked at how it functioned?… psychiatry remains the only medical specialty that rarely looks at the organ it treats.<br /><br />He suggests that if the brains of recent mentally ill mass murderers had been looked at, their crimes might have been prevented. That might be a persuasive argument if “looking at the brain” actually corresponded to understanding what the neurons were doing or had any predictive value. It doesn’t.<br /><br />https://sciencebasedmedicine.org/dr-amens-love-affair-with-spect-scans/Galen Breningstall, MDhttps://www.blogger.com/profile/07170864203251456228noreply@blogger.comtag:blogger.com,1999:blog-2186593343917545414.post-71759142370398124582017-12-20T13:47:44.640-08:002017-12-20T13:47:44.640-08:00MEET DR.
