Michael Fitzpatrick (born 1950) is a libertarian,[1] British general practitioner (GP) and author from London, United Kingdom.
[3] He has held a position as a contrarian on certain scientific issues, as he has disputed the health risks of secondhand smoke, and promoted AIDS denialism.
[4] Fitzpatrick's books have also focused on the pseudoscientific treatments for autism, such as Mark Geier's use of chelation therapy and Lupron as autism treatments, which Fitzpatrick has criticized as "dehumanising and dangerous.
"[5] He also condemned the use of secretin as an autism treatment in his 2004 book MMR and Autism: What Parents Need to Know, in which he wrote that "the secretin bubble burst" when a randomized controlled trial found that it was ineffective.
[7] He also was skeptical that Naoki Higashida, a non-speaking autistic individual, could have written the book The Reason I Jump because of the "scant explanation" of the process Higashida's mother used for helping him write using the character grid and expressed concern that the book "reinforces more myths than it challenges".
