I tried to source who said this, presumably in the 80s, but struggled. The phrase "rumors regarding players having difficulty separating fantasy from reality" appears on Wikipedia, in https://en.wikipedia.org/wiki/Dungeons_%26_Dragons#Moral_panic https://en.wikipedia.org/wiki/Dungeons_%26_Dragons#Moral_pan... but the sources aren't good (the page from theGamer is unrelated, maybe spam). https://web.archive.org/web/20200626110749/http://www.ptgptb.org/0004/hist4.html https://web.archive.org/web/20200626110749/http://www.ptgptb... has a good history of the topic, but without mention of the fantasy/reality claim. The panic made it out to be a satanic cult that induces suicide and murder. This psychiatrist was involved: https://en.wikipedia.org/wiki/Thomas_Radecki https://en.wikipedia.org/wiki/Thomas_Radecki ... however, I can't find the claim about the blurring of fantasy and reality, so maybe nobody made it, although it's kind of the theme of Mazes and Monsters.
