[A case of Alice in Wonderland syndrome after Epstein-Barr virus (EBV) encephalitis: a mimicry of focal epileptic seizure].

A 30-year-old man who received infliximab for treatment of Crohn's disease developed Epstein-Barr virus (EBV) encephalitis, which responded well to therapy; however, he had left lower visual field loss following treatment. The patient noticed peculiar symptoms 9 months after recovery from encephalitis; objects in his view appeared smaller or larger than their actual size (micropsia/macropsia). Moreover, it appeared that objects outside moved faster or slower than their actual speed of movements and moving objects appeared as a series of many consecutive snap shots. His vision was blurred, and he had visual difficulties and a sensation that his body was floating. These symptoms mainly appeared following fatigue and persisted over approximately 10 years. Based on cerebrospinal fluid analysis, brain MRI, N-isopropyl-p-123I-iodoamphetamine with single photon emission computed tomography, fluorodeoxyglucose positron emission tomography, and electroencephalography, we excluded both recurrent encephalitis and focal epileptic seizures. By taking all symptoms and other evaluation findings into account, the patient most likely suffered from "Alice in Wonderland syndrome" which is primarily associated with cortical dysfunction in the right temporo-parieto-occipital area as the consequence of previous acute EBV encephalitis.

[A patient with Alice in Wonderland syndrome]. / Een patiënt met het Alice in Wonderland-syndroom.

We present the case of a 65-year-old man who was referred to the old-age department of our psychiatric hospital because of a depressed mood and inactivity. During his stay he exhibited a variety of peculiar visual perceptions and bodily experiences. We concluded that he suffered from a severe depressive disorder, as well as from symptoms that fitted largely into the clinical pattern of the Alice in Wonderland syndrome. In this case report we discuss the symptoms, etiology, and treatment options.

Stabilization of the cervical spine through flexor endurance training for Alice in Wonderland syndrome presenting as an aura of migraine- A case report.

BACKGROUND: Alice in Wonderland Syndrome is classified as a perceptual disorder. The sufferers report episodes of distorted visual perceptions, altered body schema, and distorted experiences of time. The syndrome can be caused by migraine headaches. Migraine headaches can be caused by cervical spine instability and aberrant intersegmental motion. METHODS: Training the deep neck flexor endurance lead to a reduction in migraine headaches and in turn a reduction or secession of the Alice in Wonderland Syndrome episodes. RESULTS: There is a resolution of the Alice in Wonderland Syndrome episodes after cervical spine stabilization is achieved. CONCLUSIONS: Training of the deep neck flexors shows promise as a primary treatment of migraine headaches and should be further investigated.

Functional connectivity alterations in migraineurs with Alice in Wonderland syndrome.

BACKGROUND AND PURPOSE: Alice in Wonderland syndrome (AIWS) is a neurological disorder characterized by erroneous perception of the body schema or surrounding space. Migraine is the primary cause of AIWS in adults. The pathophysiology of AIWS is largely unknown, especially regarding functional abnormalities. In this study, we compared resting-state functional connectivity (FC) of migraine patients experiencing AIWS, migraine patients with typical aura (MA) and healthy controls (HCs). METHODS: Twelve AIWS, 12 MA, and 24 HCs were enrolled and underwent 3 T MRI scanning. Independent component analysis was used to identify RSNs thought to be relevant for AIWS: visual, salience, basal ganglia, default mode, and executive control networks. Dual regression technique was used to detect between-group differences in RSNs. Finally, AIWS-specific FC alterations were correlated with clinical measures. RESULTS: With respect to HCs, AIWS and MA patients both showed significantly lower (p < 0.05, FDR corrected) FC in lateral and medial visual networks and higher FC in salience and default mode networks. AIWS patients alone showed higher FC in basal ganglia and executive control networks than HCs. When directly compared, AIWS patients showed lower FC in visual networks and higher FC in all other investigated RSNs than MA patients. Lastly, AIWS-specific FC alterations in the executive control network positively correlated with migraine frequency. CONCLUSIONS: AIWS and MA patients showed similar FC alterations in several RSNs, although to a different extent, suggesting common pathophysiological underpinnings. However, AIWS patients showed additional FC alterations, likely due to the complexity of AIWS symptoms involving high-order associative cortical areas.

Multisensory perceptual distortion including auditory distortions in Alice in Wonderland syndrome: a case report.

Alice in Wonderland syndrome (AIWS) is a rare perceptual disorder characterized mainly by perceptual distortions of visual objects and one's own body. While there are many case reports of visual and somatosensory distortions associated with AIWS, little is known about auditory distortion. Therefore, we present the case of a 22-year-old right-handed woman who described having auditory as well as visual and somatosensory distortion experiences and a family history of AIWS. The subject reported experiencing multisensory perceptual distortions, where she sees other people's faces as larger and hears their voices as louder at the same time. This particular case suggests that auditory distortion - which contributes to constructing the perception of the surrounding space and the body - may also be characterized as a perceptual symptom of AIWS.

A CASE OF MIGRAINE WITH SYMPTOMS OF PERCEPTION DISORDERS INCLUDING A FAMILY HISTORY.

Alice in Wonderland Syndrome is characterized by distortions in perception, especially with signs of micropsia or macropsia, peropia, teleopsia.The etiology of this syndrome includes migraine attacks, epilepsy, infections or substance abuse.In this case study, a 15-year-old adolescent girl was admitted to our child and adolescent psychiatry clinic with complaints of seeing objects and people as larger or smaller than they are and/or perceiving objects closer or farther than they are, before her migraine attacks.It was also stated that his father had similar complaints during his adolescence..In this case report, we present a case of migraine with aura.

Alice in Wonderland syndrome: a lesion mapping study.

BACKGROUND AND PURPOSE: Alice in Wonderland syndrome (AIWS) is a rare neurological disorder, characterized by an erroneous perception of the body schema or surrounding space. It may be caused by a variety of neurological disorders, but to date, there is no agreement on which brain areas are affected. The aim of this study was to identify brain areas involved in AIWS. METHODS: We conducted a literature search for AIWS cases following brain lesions. Patients were classified according to their symptoms as type A (somesthetic), type B (visual), or type C (somesthetic and visual). Using a lesion mapping approach, lesions were mapped onto a standard brain template and sites of overlap were identified. RESULTS: Of 30 lesions, maximum spatial overlap was present in six cases. Local maxima were identified in the right occipital lobe, specifically in the extrastriate visual cortices and white matter tracts, including the ventral occipital fasciculus, optic tract, and inferior fronto-occipital fasciculus. Overlap was primarily due to type B patients (the most prevalent type, n = 22), who shared an occipital site of brain damage. Type A (n = 5) and C patients (n = 3) were rarer, with lesions disparately located in the right hemisphere (thalamus, insula, frontal lobe, hippocampal/parahippocampal cortex). CONCLUSIONS: Lesion-associated AIWS in type B patients could be related to brain damage in visual pathways located preferentially, but not exclusively, in the right hemisphere. Conversely, the lesion location disparity in cases with somesthetic symptoms suggests underlying structural/functional disconnections requiring further evaluation.

Jean-Martin Charcot (1825-1893) and the "Alice in Wonderland syndrome".

The "Alice in Wonderland syndrome" (AIWS) is a neurological disorder characterized by altered body schema perception, visual, or somesthetic symptoms, which is frequently associated with migraine. In this article, we present the earliest known description of symptoms attributable to AIWS in the medical literature. During a lecture held on November 22, 1887, at the Salpêtrière, Jean-Martin Charcot (1825-1893) examined a patient with somesthetic symptoms (partial macrosomatognosia) in the context of migraine with aura. Although this condition was not known at the time, Charcot tried to provide an accurate semiological and nosographic framework of this case, attributing the complex of symptoms to migraine with aura and epilepsy with sensory symptoms. With intellectual honesty and clinical prudence, Charcot correctly pointed to a disturbance in the excitability of cortical areas responsible for processing and perceiving sensory stimuli.

Infectious causes of Alice in Wonderland syndrome.

Alice-in-Wonderland syndrome (AIWS) is a perceptual disorder embracing a spectrum of self-experienced paroxysmal body image illusions including most commonly distortions of shape (metamorphopsia), size (macropsia or micropsia), distance (pelopsia or teleopsia), movement, and color among other visual and somesthetic distortions. Depersonalization, derealization, and auditory hallucinations have also been described. Recent reports suggest that infectious diseases are the predominant etiology for AIWS, especially among children. This article reviews current understanding regarding the association between infection and development of AIWS.

Síndrome de Alicia en el país de las maravillas secundario a consumo de montelukast. Presentación de caso / Alice in wonderland syndrome secondary to medication with montelukast. Case presentation

RESUMEN La condición neurológica definida por la aparición de alteraciones en la percepción, usualmente interpretada como fenómenos extraños de metamorfosis y despersonalización, se reconoce como síndrome de Alicia en el país de las maravillas. Se presenta el caso de una paciente femenina de 9 años de edad, con el diagnóstico de síndrome de Alicia en el país de las maravillas secundario a medicación crónica con montelukast. El diagnóstico del síndrome psiquiátrico se realizó teniendo en consideración los antecedentes patológicos personales y el examen físico. El síndrome de Alicia en el país de las maravillas tiene un carácter benigno, sumamente infrecuente, y aunque su etiología no es del todo conocida, su aparición como reacción adversa a medicamentos es una opción que debe ser siempre considerada por el médico actuante (AU).

ABSTRACT The neurological condition defined by the appearance of alterations in perception usually interpreted as strange phenomena of metamorphosis and depersonalization is recognized as Alice in wonderland syndrome. The case of a 9-year-old female patient is presented, with the diagnosis of Alice in Wonderland syndrome secondary to chronic medication with montelukast. The diagnosis of the psychiatric syndrome was made taking into account personal pathological history and physical examination. Alice in Wonderland syndrome has a benign, extremely rare character and although its etiology is not fully known, its appearance, as an adverse reaction to medications, is an option that should always be considered by the acting physician (AU).

Prevalence and characteristics of Alice in Wonderland Syndrome in adult migraineurs: Perspectives from a tertiary referral headache unit.

BACKGROUND: Migraine affects how the brain processes sensory information at multiple levels. The aberrant integration of visual and somatosensory stimuli is thought to underlie Alice in Wonderland Syndrome, a disorder often reported as being associated with migraine. However, there is still a lack of knowledge about the epidemiology of this syndrome in migraineurs and the association between Alice in Wonderland Syndrome episodes and migraine attacks. Therefore, we conducted a prospective cohort study to systematically evaluate the prevalence and the clinical features of Alice in Wonderland Syndrome in a large sample of patients with migraine. METHODS: All the patients attending for the first time a tertiary-level headache clinic were consecutively screened for Alice in Wonderland Syndrome symptoms by means of an ad hoc questionnaire and detailed clinical interview, over a period of 1.5 years. Patients experiencing Alice in Wonderland Syndrome symptoms were contacted for a follow-up after 8-12 months. RESULTS: Two hundred and ten patients were recruited: 40 patients (19%) reported lifetime occurrence of Alice in Wonderland Syndrome, 90% of whom (38/40) had migraine with aura. Thirty-one patients experienced episodes of Alice in Wonderland Syndrome within 1 h from the start of migraine headache. Patients reported either visual or visual and somatosensory symptoms (i.e. somatosensory symptoms never presented alone). We collected the follow-up details of 30 patients with Alice in Wonderland Syndrome, 18 of whom had been prescribed a preventive treatment for migraine. After 8-12 months, 5 of the treated patients reported a decrease, while 13 reported no episodes of Alice in Wonderland Syndrome. CONCLUSION: Alice in Wonderland Syndrome prevalence in migraineurs was found to be higher than expected. Alice in Wonderland Syndrome was mostly associated with migraine with aura and tended to occur close to the migraine attack, suggesting the existence of a common pathophysiological mechanism. Patients treated with migraine preventive treatments had a higher chance of decreasing or even resolving Alice in Wonderland Syndrome episodes.
