'Alice in Wonderland Syndrome' Caused by Acid Flashback

Lewis Carroll's delightful children's novel "Alice's Adventures in Wonderland" turns 150 this year. But there's another, less celebrated Wonderland-related anniversary occurring this year: the discovery of "Alice in Wonderland syndrome" (AIWS), a disorder named in honor of the book. This syndrome, named in 1955 by British psychiatrist John Todd, has long been known to co-occur with some migraines. A new case study, however, reveals that headaches aren't the only cause of AIWS. The patient in the study, a 26-year-old man, came to psychiatrists with a history of using alcohol, marijuana and LSD (lysergic acid diethylamide, a psychedelic drug). During LSD trips, the man said, he'd frequently perceive objects and people all out of proportion— things would look too big, too small, or farther or closer than they actually were.
