The Most Important Lesson From 83,000 Brain Scans

Daniel Amen is an American psychiatrist and brain disorder specialist who is a strong advocate of utilizing single photon emission computed tomography (SPECT) as a diagnostic tool for better identifying and treating mental illnesses. In the following TED Talk, he discusses his research involving the use of SPECT (including several touching success stories resulting from its application) and highlights its importance in improving the efficacy of psychiatric treatment.

Personally, I found Amen’s points to be compelling and reasonable. The growing prominence of psychiatric problems in our society, coupled with issues of inaccurate diagnosis and inadequate treatment, makes his argument for the wider use of SPECT seem self-evidently true.

However, after doing some research, I dug up quite a lot serious skepticism and criticism towards Amen’s claims, as well as his professional endeavors (apparently, he hawks a lot of pseudoscience while making hefty profits from his private practice). Much of the controversy and debate is cited and expanded upon in this article from Science Based Medicine, a source I deeply trust.

Personally, I remain undecided, as I just came across Amen and his subsequent detractors. I will have to look into these matters more deeply when I have the time, but I invite you all to see the video, read the criticism, and decide for yourselves. As always, feel free to weigh in with your thoughts here. Thanks for reading.
