Alice in wonderland syndrome (AWS) also known as Todd syndrome or dysmetropsia. In 1955, a psychiatrist called John Todd named it as Todd syndrome.
If you have read the 18th century novel “Alice’s Adventures in Wonderland” written by Lewis Carroll or watched the movie Alice in Wonderland, the protagonist Alice grows too tall for the house, just like her the ones suffering from this syndrome will hear sounds either quieter or louder than they are, see objects larger or smaller than reality, this occurs due to abnormal amounts of electrical activity resulting in abnormal blood flow in the parts of the brain that process visual perception and texture..
Fortunately, Alice in Wonderland Syndrome is extremely rare but research suggests that it mainly occurs in children and adolescents. There are no customary standards for diagnosing this syndrome.
Interestingly AWS symptom micropsia (a neurological condition affecting human visual perception, objects appear smaller than normal) has been related to Jonathan Swift’s novel Gulliver’s Travels. It is also known as “Lilliput sight” and “Lilliputian hallucination“, which was coined by British physician Raoul Leroy in 1909, descended from the small people that tenanted the island of Lilliput in the novel.
