SPECT Imaging Notes: More On "Celiac Brain" Hypofunction
Posted Sep 16 2008 5:00am
Brain changes do appear on SPECT imaging with bowel immune dysfunction: think gluten sensitivity and celiac. Seeing real pathological evidence, bottom to top, does help with believing.
Just a few months ago we reported at CorePsychBlog the interesting findings, reported in the Annals of Internal Medicine, of all places, on SPECT brain imaging, celiac and a clearing of schizophrenic symptoms when the gluten sensitivity was effectively treated.
Just below: a typical brain image we often see using SPECT imaging for individuals with immune dysregulation. So many articles are coming up regarding brain imaging with SPECT with celiac I thought you would like to see the actual brain level findings that we see in our office.
Here you can easily see the temporal lobe and prefrontal hypoperfusion, so often referenced in the literature, that lead us to always chase down possible immune dysfunction/bowel/celiac issues as reported in the article below. -Yes, a picture is worth a thousand words...
Frontal cortical perfusion abnormalities related to gluten intake and associated autoimmune disease in adult coeliac disease: 99mTc-ECD brain SPECT study. Usai P et al. Dig Liver Dis. 2004; 36(8): 513-8
See the conclusions below:
RESULTS: Twenty-four out of 34 patients (71%) showed brain single-photon emission computed tomography abnormalities confirmed by abnormal regional asymmetry index (>5%; range 5.8-18.5%). Topographic comparison of the brain areas showed that the more significant abnormalities were localised in frontal regions, and were significantly different from controls only in coeliac disease patients on unrestricted diet. The prevalence of single-photon emission computed tomography abnormalities was similar in coeliac disease patients with (74%) and without (69%) associated autoimmune disease. CONCLUSIONS: Abnormalities of brain perfusion seem common in coeliac disease. This phenomenon is similar to that previously described in other autoimmune diseases, but does not appear to be related to associated autoimmunity and, at least in the frontal region, may be improved by a gluten-free diet.
These interesting articles reveal the growing interface between brain and body evidence in immune dysfunction. It's interesting to bring these brain studies together with real office laboratory findings that confirm the pathophysiology on a gut cellular level.
Of further interest: SPECT is demonstrating changes in mold neurotoxin, neuroimmune conditions as well - more on mold findings in a later post.
