Alice in Wonderland syndrome (AIWS) is a relatively uncommon disorder with serious consequences for a person's quality of life. Alice in Wonderland syndrome (AIWS), also known as Todd's syndrome, is a neurological condition that leads to perceptual distortions. These distortions may involve altered perceptions of size, distance, time, and the position or shape of objects. The name of the syndrome is inspired by Lewis Carroll's famous novel "Alice's Adventures in Wonderland", in which the protagonist, Alice, experiences similar shifts in perception.
Symptoms of AIWS can include:
Micropsia: Objects appear smaller than they actually are.
Macropsia: Objects appear larger than they actually are.
Teleopsia: Objects appear further away than they actually are.
Pelopsia: Objects appear closer than they actually are.
Temporal Disintegration: Altered perception of time, where it may seem to pass faster or slower than in reality.
Somatoparaphrenia: The sensation that a specific body part has changed size.
Distorted spatial perception: Feeling that the ground is tilting or that walls are closing in.
AIWS-induced perception distortions can be distressing and disorienting, leading to feelings of confusion and anxiety (Blom, 2016). Individuals with AIWS may struggle with daily activities such as reading, writing, or driving due to visual distortions (Farooq & Fine, 2017). Some people may also be self-conscious about how their bodies appear to others, which can have an impact on their social interactions (Harrison & Harrison, 2015). One of the most distressing symptoms of AIWS is a sense of being disconnected from one's own body, which can lead to feelings of alienation and confusion.
There are various types of AIWS based on which sense is affected. Visual AIWS is the most common type, and it is characterized by visual distortions such as micropsia or macropsia (Blom, 2016). Other types of AIWS include auditory AIWS, which is defined by auditory distortions, and somatosensory AIWS, which is defined by distortions in touch or body image perception (Lerner & Ran, 2015). In some cases, the individual may experience multiple types of AIWS, making the disorder even more difficult to manage. Individuals with AIWS may also experience symptoms such as dizziness, nausea, and disorientation.
Some research has suggested a link between AIWS and brain tumors, brain injury, or psychiatric conditions such as schizophrenia (Förstl et al., 2015). It is important to note, however, that the majority of cases of AIWS are unrelated to any underlying medical condition and are thought to be caused by migraines (Blom, 2016). Furthermore, some researchers believe that AIWS is linked to changes in the brain's electrical activity, which can cause disruptions in perception.
Migraines are a common cause of AIWS, and the visual distortions are thought to be caused by changes in blood flow to the brain during a migraine (Beh et al., 2018). Individuals suffering from migraines are more likely to experience visual distortions such as micropsia or macropsia, according to research (O'Toole & Modestino, 2017). Migraine treatment may help to alleviate the symptoms of AIWS. Medications such as anti-seizure medications and antidepressants may also be prescribed to help manage AIWS symptoms.
There is no specific treatment for AIWS at the moment, but management of the disorder is based on addressing the underlying cause. For example, if migraines are discovered to be the underlying cause, migraine treatment may be prescribed (Yokoyama et al., 2017). Treatment may include surgery or other medical interventions if the disorder is caused by a brain tumor or injury (Garcia-Cabo et al., 2019). Individuals with AIWS may benefit from therapy or counseling to help them cope with the disorder's emotional and psychological effects (Jia & Miao, 2018). Alternative therapies such as acupuncture and massage may also be beneficial in managing the symptoms of AIWS.
AIWS is a relatively rare disorder, and treatment options such as repetitive transcranial magnetic stimulation (Lerner & Ran, 2015) and cognitive-behavioral therapy (Fine et al., 2019) can provide valuable insights into the disorder. Furthermore, a bibliometric study by (Hossain, 2020) emphasized the importance of global AIWS research to advance our understanding of the disorder and improve treatment outcomes. Overall, raising awareness and conducting research on AIWS is critical in order to improve the quality of life for those affected by this disorder.
Furthermore, the impact of AIWS on different populations must be considered, as studies have revealed that the disorder manifests differently in children and adolescents, as well as in patients with vestibular migraine (Farooq & Fine, 2017). (Beh et al., 2018). Furthermore, research has found that AIWS can have a significant impact on a person's perception of time (Jia & Miao, 2018) and body image (Pitron et al., 2018). These findings highlight the importance of additional research in order to fully comprehend the complexities of AIWS and provide tailored treatment options for different populations. For example, therapy and counseling tailored specifically for children and adolescents may be more effective than the same treatment options provided to adults in managing their symptoms.
AIWS is most commonly reported in children and often diminishes as they grow older, although adults can experience it as well. Most episodes are brief, lasting a few minutes to half an hour. However, they can be disorienting and distressing to the person experiencing them.
If someone thinks they might have AIWS, it's essential to see a doctor, as the symptoms can be similar to those of other more serious conditions. A thorough evaluation can help determine the cause and guide any necessary treatment or interventions.
