Alice in Wonderland Syndrome: Rare Mental Health Disorder

I have always been fascinated by the human brain – a complex web of nerves governing our thoughts and actions. Have you ever wondered what it’s like when sizes and shapes trick your mind? Let’s explore a rare neurological disorder called Alice in Wonderland Syndrome (AIWS).

Discovery and Naming of Alice in Wonderland Syndrome

Alice in Wonderland Syndrome (AIWS) is also known as Todd’s syndrome. AIWS is a neurological disorder that leaves individuals disoriented about the shape, size of themselves, and the world around them, often accompanied by alteration in occurrence of time.

It was described by Caro Lippman in 1952. The syndrome earned its name from John Todd in 1955. Todd’s study, which included six cases, primarily highlighted symptoms involving a distorted sense of body size—parts of or the entire body appearing larger or smaller than usual.

The name of the syndrome finds its roots in Lewis Carrol’s renowned children’s book “Alice’s Adventures in Wonderland” where the title character undergoes experiences of parts of her body changing shape, and size, in the relationship of the rest of her body.

Symptoms: Visual Illusions and Altered Consciousness

Individuals experiencing Alice in Wonderland Syndrome (AIWS) may undergo alterations in perception.

These symptoms are linked to visual illusions, where objects or individuals seem bigger, smaller, farther, or closer than reality, alongside disorders of consciousness, including feelings of derealization, depersonalization, somatopsychic duality (i.e., the idea of being split in two, more often vertically in the middle), and alterations in the perception of time.

Hallucinations or illusions of expansion, reduction, or distortion of one’s body image are also common. Alice in Wonderland Syndrome (AIWS) can manifest at any age but is more prevalent during childhood and adolescence.

What Causes Alice in Wonderland Syndrome?

Complete or partial forms of Alice in Wonderland syndrome (AIWS) can occur in a variety of disorders such as migraines, epilepsy, intoxicants, infectious states, and febrile deliria to brain lesions such as tumors.

Notably, Epstein-Barr virus (EBV) infection is a common cause in children, while migraines are more frequently associated with adults.

Investigation of AIWS

Since 1955, around 170 cases of Alice in Wonderland Syndrome (AIWS) have been reported in the medical literature. 

Until now, only a few of them fit Todd’s description of disease, and therefore the inclusion in Alice in Wonderland Syndrome (AIWS) definition seems questionable for some of the reported cases. 

However, the current diagnosis standard for Alice in Wonderland Syndrome (AIWS) involves thorough investigations like blood tests, EEG (electroencephalogram), and brain MRI.

A case involving brain imaging with contrast during an Alice in Wonderland Syndrome (AIWS) episode revealed decreased cerebral perfusion in various brain lobes, suggesting a link between decreased perfusion in visual pathways or centers.

Most patients tend to outgrow these episodes.

Challenges in the Diagnosis of AIWS

Despite its intriguing nature, Alice in Wonderland Syndrome (AIWS) remains poorly understood and is often misdiagnosed due to the lack of clear diagnostic criteria.

Treatment is directed at addressing the underlying condition, and the long-term prognosis depends on the specific etiology.

Join the Conversation

In short, Alice in Wonderland Syndrome (AIWS) alters perception of size, shape, and time, creating illusions similar to Alice’s experiences in Lewis Carroll’s book. Its diverse causes make diagnosis challenging, often leading to misdiagnosis.

Below you can find some Medical Terminologies related to Alice in Wonderland Syndrome (AIWS)

• Macropsia– Objects appearing large.
• Micropsia– Objects appearing small.
• Teleopsia– Objects appearing further away.
• Pelopsia– Objects appearing closer.
• Microsomatognosia– Feeling that one’s body or body parts are shrinking.
• Macrosomatognosia– Feeling that one’s body or body parts are growing inexplicably taller or larger.
• These alterations collectively fall under the umbrella of metamorphopsias or Lilliputian hallucinations.
