Abstract

Alice in Wonderland syndrome is a process characterized for complex disorders of the visual perception with multiple etiologies.To evaluate the clinical, electrophysiological, etiological characteristics and natural evolution in children with Alice in Wonderland syndrome.We have realized a retrospective study by what means of a review of 20 clinical histories of 18 year old minor patients diagnosed of Alice in Wonderland syndrome from January 1995 until February 2010.The average of age to the diagnosis was 9.5 ± 3.8 years (range: 4-16 years). It appeared in an acute way in 85% and progressive in 15%. 90% had micropsias and/or macropsias, 85% distortion of the form of the objects, 80% displacement of objects, 45% disturbances of body image, 45% acceleration of the time and 30% sensation of unreality. 95% of the children had many episodes a day; these episodes lasted less than 3 minutes in 90%. Electroencephalogram was realized in all the patients, it was abnormal in 11 cases, in one case was found and epileptic foci (left temporal) and in 10 cases was found posterior slow waves. The tests of neuroimagen were normal in all the patients. The visual evoked potentials were realized in 7 children; five of these children showed higher amplitude in evoked potentials and two of these children had normal. The infectious etiology was found in nine cases (five partners to Epstein-Barr virus), migraine in eight, toxins in two and epilepsy in one case. 80% did not have recurrence.Alice in Wonderland syndrome is a benign process with trend to spontaneous resolution and without recurrence in the majority of the occasions. The principal etiologies are migraine and Epstein-Barr virus infection.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-07-22:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 20.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 39 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 8.
