ABSTRACT
This chapter presents a case of a 19-year-old woman who comes to clinic and describes that she is worried by experiences where the usual sounds in the room begin to fluctuate in intensity, almost like they are coming from a radio with the sound being altered. A full neurological examination is normal. The differential diagnoses would include complex partial epilepsy, psychoactive drug use (e.g. cannabis or magic mushrooms), migraine, early psychosis, severe sleep deprivation, severe stress, space-occupying lesion or feigned illness. Further tests were discussed but mutually agreed not to be necessary. The general practitioner referred the patient to a neurologist who diagnosed migraine using the term 'Alice in Wonderland syndrome'. This was coined by Todd in 1955, because of the various instances of metamorphopsia, micropsia and macropsia described in the tale where Alice perceived herself to be smaller, changing shape and objects around her to be changing in size.
