Alice in Wonderland Syndrome (AIWS) when you hear the Alice in Wonderland Syndrome I am certain that the primary thing that will jump up in your brain is one of the most popular novels Alice in Wonderland. But rather I will talk about one of the rarest neuropsychological disorders also known as Todd’s syndrome or Dysmetropsia.

It is the disorder of visual perceptions where the person gets hallucinated. The person may find that they are confused as to the size and shape of the parts of their body. They may feel as though something is happening to their body likewise expanding or getting smaller. AIWS also involves perceptual distortions of the size or shape of the objects.


This syndrome is described and named by the English psychiatrist John Todd in 1955. He named the syndrome after Lewis Carroll’s novel (Alice’s Adventures In Wonderland). In his publication, Todd proposed grouping the symptoms experienced by Alice (“Hyperschematia, Hyposchematia,  and Somatopsychic duality”) together with other symptoms that often accompany them such as “illusory changes in the size, distance, or position of stationary objects in the subject’s visual field, illusory feelings of levitation; and illusory alterations in the sense of the passage of time”.

 Todd also noted that patients are often aware of their situation, differentiating this condition from psychoses in which insight is usually impaired.


The basic causes are:

  1. Migraine
  2. Fever
  3. Depression
  4. Infectious mononucleosis
  5. Epilepsy
  6. Coxsackievirus B1 infection
  7. Adverse drug reaction of topiramate
  8. H1N1 viral infection
  9. Schizoaffective disorder
  10. Lyme disease
  11. Cerebral lesions
  12. Viral infection
  13. Brain tumour


The symptoms for AIWS are as follows:

  1. Micropsia – It is the condition that affects human visual perception in which objects are seen to be smaller than they are.
  2. Macropsia – It is the condition in which objects appear to be larger than they are.
  3. Teleopsia – It is the situation in which objects appear much farther away than they are.
  4. Palinopsia – It is the situation where the person continues to seem to look at the image of an object they were looking at even after they have stopped looking at it.
  5. Metamorphopsia – In this defect causes linear objects to look curvy or rounded.
  6. Headaches and anxiety
  7. Visual hallucinations
  8. Giddiness
  9. The sensation of being ‘split’
  10. Derealisation
  11. Depersonalization
  12. Paresthesia – It is like a tingling or prickling sensation usually in arms, hands, legs, or feet.
  13. Hyperacusis – It is a debilitating hearing disorder where everyday sounds seem much louder than they are.
  14. Tinnitus and blurring of vision
  15. Lilliputians and allesthesia
  16. Diploid images and panic or agitation
  17. Sense of time slowing down


  • It affects children and is most common in females.
  • Blood tests
  •  Brain MRI
  • Electroencephalography(EEG)


The bodily-related distortions can repeat few times a day and may set aside some effort to decrease. Naturally, the individual can get scared, frightened, and panic-stricken throughout the hallucinations; maybe even hurt themselves or others around them.

 The side effects of the syndrome are not harmful and are likely to disappear with passing time. Since this disease is diagnosed when the patient is a child, there is a 90% chance they will outgrow it by early adulthood. Some children grow out of the disease in one month of being diagnosed.


There is no such treatment for Alice In Wonderland Syndrome. The person gets better with time and growing age. Some drugs can be given for the treatment of migraine and some other infections and a proper and healthy lifestyle should be maintained.


All in all, what is at present likely alluded to as AIWS incorporates some exceptionally heterogeneous conditions. In the future, further examination meaning to more readily characterize the measures of this disorder are justified, especially taking into account the conceivable cover with other uncommon disorders that include contortions in the view of body parts like Cotard’s condition or Koro disorder (hallucination of a contracting penis).

 Future advances in the comprehension of the neurobiology fundamental ‘positive’ visual bends will help illuminate regardless of whether AIWS ought to be viewed as an unmistakable condition.
