In the guest editorial of the same issue of the Canadian Journal of Psychiatry, Dr. [...] Although the author noted the role of functional brain imaging with PET and SPECT in the differential diagnosis of dementia, and in exploring the actions of antipsychotic and antidepressant medications, he underlined that we have a very immature understanding of “how receptor binding relates to symptom improvement”. [...] The authors found that there was “limited overlap between the brain regions identified using differing imaging methods.” They concluded that “the study has identified a complex network of brain regions involved in the pathophysiology of MDD” and they invited future researchers “in particular to try and delineate the brain areas involved in the primary 42 pathophysiological change and areas in whic [...] The quality of the scan images used for the study should be compatible to the current disease-specific SPECT image patterns that construct the norms in the current peer- reviewed literature. [...] Regence considers SPECT as “investigational for evaluation of ADHD, dementias, and all other psychiatric conditions.” They state that currently available studies are preliminary and have not added to the body of knowledge with regards to the clinical utility of SPECT in diagnosis and management of ADHD, dementias or other psychiatric conditions.
