Alice in Wonderland Syndrome
Case Study 1
Steroid-Induced Psychosis Presenting as Alice
in Wonderland Syndrome
Patient X: a 40 year old Male
Past Medical History
- Renal tubular acidosis, bronchial asthma and hypertension
- Had good reasoning, judgement, coherent,
- Tremors of fingers, anxious, and tremulous voice
- Auditory and visual hallucinations
-"Couldn't tell illusions from reality"
- Symptoms began about 6 months after he was started on high doses of steroids.
Case interesting because patient’s psychotic symptoms were misdiagnosed as schizophrenia
Case Study 2
Patient Y: 7 year old girl
Distorted images - Her mother’s hands appeared being green and abnormally small when compared to the rest of her body.
Attacks that would last a few minutes
Normal brain scans but the presence of the EBV
All of her color vision at the eye level was completely normal.
No agnosia (the inability to recognize sounds, objects, or smells even though there is no problem with memory or the sensory organs themselves)
No dysphasia (inability to speak)
By: Humzah Nasir
- Disease first identified in 1955 by John Todd
- Named after Lewis Carroll’s
The Adventures of Alice in Wonderland
- Typically manifests in childhood; benign, self-terminating
- Found in association with variety of disorders: migraines, epilepsy, EBV, cerebral lesions, intoxication with hallucinogenic drugs
- Found in patients with family history of migraines and epilepsy
Distorted body image perceptions
Body parts (hands, feet, head) seem to be larger/smaller; surrounding objects and images are much larger/smaller and closer/farther than they should be
-Micropsia or Macropsia
Skewed sense of time, sound, touch
Time seems to move abnormally quickly or slowly; sound is distorted; ground feels spongy and patients feel like they are in quicksand
-Distortions can recur several times a day and may take some time to abate. the sufferer can become alarmed, frightened, even panic-stricken.
-Symptoms not harmful and likely to disappear with time.
- Migraine prophylaxis, i.e., anti depressants, anti convulsants, and calcium channel blockers.
- Strict migraine diet (steer clear of chocolates, meat, refined sugar, refined flour and most denatured foods).
- AIWS symptoms that have been triggered by migraines diminish with changes in diet and lifestyle; that ward off episodes of migraine.
-Most common virus found in humans
-Can cause IM which can lead to AIWS
Temporal Lobe Epilepsy
-Recurrent seizures in temporal lobe
-Altered sensations (ex. smell)
-Causes disturbances in memory
AIWS is a neurological disorder which can cause distortions in the perceptions of: image, body, time, touch and sound
Distortions caused by abnormal electrical activity causing problems with the amount of blood that flows to the visual and texture processing centers of the brain
Functional MRI of a child with Alice in Wonderland Syndrome during an episode of micropsia
Patient: 12-year-old boy with viral-onset AIWS
fMRI was conducted in response to
1) Passive viewing task (reversing checkerboard)
2) Active viewing task (line-length decisions in the context of the Ponzo illusion).
In passive, hypoactivation limited to the left hemisphere of the calcarine gyrus, with no differences between participants in other occipital ROIs
For the active viewing task, the child with AIWS had more extensive hypoactivation, in both the calcarine and lingual gyrus ROIs bilaterally
Results consistent with studies of viral-onset AIWS with abnormal EEG patterns and hypoperfusion in occipital regions
In AVT, which requires visual perception, attention, and size comparison between two visual stimuli, found hyperactivation of right superior parietal cortex as well as bilateral inferior parietal cortical regions AIWS child reactive to the control participant
Consistent pattern of occipital hypoactivation and parietal hyperactivation
Complex Hallucinations and Panic Attacks in a
13-year-old with Migranes
Patient: 13 year old girl
Family history of migraine, epilepsy, depression, and substance abuse
: Hearing voices in head, time moving abnormally slowly, loss of strength in hands
: Pizotifen reduced frequency and intensity of migraines; also reduced perceptual disturbance and anxiety. Addressed anxiety through psychoeducation, relaxation training, cognitive behavior therapy
