Abstract
Kluver-Bucy Syndrome (KBS) is a rare neuropsychiatric disorder characterized by hyperorality, hypersexuality, bulimia, visual agnosia, and amnesia due to lesions affecting bilateral temporal lobes. It is attributed to a multitude of causes, including stroke, herpes simplex encephalitis, Alzheimer's disease, and head trauma. Current treatments for KBS include symptomatic management with antipsychotics, mood stabilizers, carbamazepine, and selective serotonin reuptake inhibitors. The bibliometric analysis was done to reflect the relevance and understanding of KBS in recent literature. The SCOPUS database was utilized to conduct a search for all articles with the terms "Kluver-Bucy" and "Kluver Bucy" from January 1, 1955 (the first available articles from the search) to February 1, 2023. The parameters included in this analysis were article title, citation numbers, citations per year, authors, institutions, publishing journals, country of origin, Source Normalized Impact per Paper, and Scopus CiteScore. Since 1937, when Kluver-Bucy Syndrome was first defined, the publications on KBS have steadily increased, with up to six publications a year in 2002. The most common institutions were SUNY Upstate Medical University, VA Medical Center, and the State University of New York (SUNY) System. Seven of these papers were published in Neurology. Almost 75% of the articles were published in journals of medicine and neuroscience. This is the first bibliometric analysis to evaluate the most influential publications about Kluver-Bucy Syndrome. A majority of the research is case-based and there is a dearth of clinical trials to identify the exact pathophysiology and physiotherapy management, possibly owing to the rarity of the disease. Our research suggests that there may be a significant overlap between Sanfilippo syndrome and KBS, suggesting that refined guidelines for establishing diagnosis may be required for children. Our study could bring a renewed interest in this field and lead to additional research focused on understanding the pathophysiology of KBS in order to promote the development of novel diagnostics and treatment.

Abstract
Kluver-Bucy syndrome (KBS) is a characterized by a group of cognitive dysfunctions that include hypersexuality, placidity, hyperorality, memory deficits and hypermetamorphosis. This syndrome is often seen in pathological states that destroy the temporal lobes, normally bilaterally. Herpes simplex encephalitis (HSE) is one of the causes of KBS, as the herpes virus can cause dysfunction/destruction of the temporal lobes. KBS is a very rare syndrome, with just a few cases described in the literature. We present the case of a 21-year-old-man who was diagnosis with KBS after HSE. LEARNING POINTS Kluver-Bucy syndrome (KBS) should be kept in mind in patients with visual agnosia, hypermetamorphosis, memory disturbances, hypersexuality and placidity.Neurological causes of KBS should be treated quickly.Treatment of KBS is still very challenging.

Abstract
Klüver-Bucy syndrome (KBS) leads to important behavioral symptoms and social maladaptation. Rarely described, no previous study has investigated its social and affective cognitive profile. We report the case of ASP, a patient who developed a complete KBS at 9 years that evolved into an incomplete KBS. Orbitofrontal and temporal damages were evidenced. While a classic neuropsychological assessment showed a preserved global functioning, an extensive evaluation of her social and affective cognition (reversal learning, decision-making, emotion recognition, theory of mind, creative thinking) showed remarkable deficits. The relevancy of such findings for the characterization KBS and the field of neuropsychology are discussed.

Abstract
Klüver-Bucy syndrome (KBS) comprises a set of neurobehavioral symptoms with psychic blindness, hypersexuality, disinhibition, hyperorality, and hypermetamorphosis that were originally observed after bilateral lobectomy in Rhesus monkeys. We investigated two siblings with KBS from a consanguineous family by whole-exome sequencing and autozygosity mapping. We detected a homozygous variant in the heparan-α-glucosaminidase-N-acetyltransferase gene (HGSNAT; c.518G>A, p.(G173D), NCBI ClinVar RCV000239404.1), which segregated with the phenotype. Disease-causing variants in this gene are known to be associated with autosomal recessive Mucopolysaccharidosis type IIIC (MPSIIIC, Sanfilippo C). This lysosomal storage disease is due to deficiency of the acetyl-CoA:α-glucosaminidase-N-acetyltransferase, which was shown to be reduced in patient fibroblasts. Our report extends the phenotype associated with MPSIIIC. Besides MPSIIIA and MPSIIIB, due to variants in SGSH and NAGLU, this is the third subtype of Sanfilippo disease to be associated with KBS. MPSIII should be included in the differential diagnosis of young patients with KBS.

Abstract
Klüver-Bucy syndrome (KBS) is a behavioral phenotype that appears most often after bilateral temporal damage. The main features of KBS are compulsion to examine objects orally, increased sexual activity, placidity, hypermetamorphosis (irresistible impulse to notice and react to everything within sight), visual agnosia, and problems with memory. It is more rarely reported in children than in adults. We present a case of KBS in a 2-year-old boy with tuberous sclerosis complex (TSC) after left frontotemporal resection for refractory epilepsy. This is the first KBS after unilateral temporal resection in a child, although it has already been reported in two adult cases. It also is the first case reported in a TSC patient.

Abstract
Mucopolysaccharidosis Type IIIA (MPS IIIA) is a neurodegenerative disease with behavioral symptoms unique among the mucopolysaccharidoses. Children with MPS IIIA reportedly mouth things, explore novel environments almost continuously, disregard danger, and empathize/socialize and comply less with parents. These characteristics resemble Klüver-Bucy syndrome (K-Bs). To test the K-Bs hypothesis, 30 children with MPS IIIA were compared to 8 "posttransplant" mucopolysaccharidosis Type IH patients in an experimental "risk room." The room contained attractive and mildly frightening objects, exposure to a 92-dB startle noise triggered by contact with an attractive toy, mother's return after a brief absence, and compliance with her cleanup directive. Children with MPS IIIA: (a) left mother sooner, (b) wandered more, (c) were more likely to approach frightening objects, (d) were less likely to respond to loud noise with whole body startle, (e) were less likely to avoid the toy associated with the startle noise, (f) interacted less with mother upon her return, and (g) complied less with her cleanup command. K-Bs is associated with loss of amygdala function. Brain magnetic resonance imaging (MRI) of a subset of the children with MPS IIIA showed volume loss that was greater in the amygdala than in the hippocampus; only amygdala loss correlated with reduced fearfulness. MPS IIIA may be the first identified pediatric disease presenting systematically as a K-Bs variant. If validated by further studies, the K-Bs hypothesis of MPS IIIA would provide important clinical and theoretical information for the guidance of families as well as markers for natural disease progression and treatment effects.

Abstract
The Klüver-Bucy syndrome (KBS) is characterized by a number of peculiar behavioral symptoms. The syndrome was first observed in 1939 by Heinrich Klüver and Paul Bucy in the rhesus monkey following removal of the greater portion of the monkey's temporal lobes and rhinencephalon. The animal showed (a) visual agnosia (inability to recognize objects without general loss of visual discrimination), (b) excessive oral tendency (oral exploration of objects), (c) hypermetamorphosis (excessive visual attentiveness), (d) placidity with loss of normal fear and anger responses, (e) altered sexual behavior manifesting mainly as marked and indiscriminate hypersexuality, and (f) changes in eating behavior. In humans, KBS can be complete or incomplete. It occurs as a consequence of neurological disorders that essentially cause destruction or dysfunction of bilateral mesial temporal lobe structures (i.e., Pick disease, Alzheimer disease, cerebral trauma, cerebrovascular accidents, temporal lobe epilepsy, herpetic encephalopathy, heat stroke). As for epilepsy, complete and incomplete KBS are well documented in temporal lobe epilepsy, temporal lobectomy, and partial status epilepticus. KBS can occur at any age. Children seem to show similar symptoms to adults, although some differences in the manifestations of symptoms may be related to the fact that children have not yet learned certain behaviors.

Abstract
CONTEXT Sexual sadism is a psychiatric disorder in which sexual pleasure is derived from inflicting pain, suffering, or humiliation on others. While the psychological and forensic aspects of sexual sadism have been well characterized, little is known about the neurocognitive circuitry associated with the disorder. Sexual sadists show increased peripheral sexual arousal when observing other individuals in pain. The neural mechanisms underlying this unusual response are not well understood. We predicted that sadists relative to nonsadists would show increased responses in brain regions associated with sexual arousal (amygdala, hypothalamus, and ventral striatum) and affective pain processing (anterior cingulate and anterior insula) during pain observation. OBJECTIVE To study the neural correlates of pain observation in sadists and nonsadists. DESIGN Case-control cross-sectional study. Sadists and nonsadists viewed 50 social scenes, 25 that depicted a person in pain (eg, one person stabbing another person's hand with scissors) and 25 thematically matched no-pain pictures (eg, one person stabbing a table with scissors, with another person's hand nearby). Pain severity ratings (range, 0 [none] to 4 [severe]) were acquired following each picture presentation. SETTING Sand Ridge Secure Treatment Center, Mauston, Wisconsin. PARTICIPANTS Fifteen violent sexual offenders, including 8 sadists and 7 nonsadists (defined using the Severe Sexual Sadism Scale) who were matched for age, IQ, and education. MAIN OUTCOME MEASURES Hemodynamic response revealed by functional magnetic resonance imaging and pain severity ratings. RESULTS Sadists relative to nonsadists showed greater amygdala activation when viewing pain pictures. They also rated pain pictures higher on pain severity than nonsadists. Sadists but not nonsadists showed a positive correlation between pain severity ratings and activity in the anterior insula. CONCLUSION These results provide neurobehavioral evidence of unusually heightened sensitivity to the pain of others in sadists.

Abstract
Klüver-Bucy syndrome may result from affection of various location of brain. We report a case of Klüver-Bucy syndrome associated with isolated bilateral hippocampal atrophy without any abnormal lesion in other areas following status epilepticus. A 31-year-old man who had no significant medical history presented with status epilepticus after encephalitis of unknown etiology. He had been recovered from status epilepticus three weeks later, but afterwards he developed Klüver-Bucy syndrome: hyperphagia, hypersexuality, hypermetamorphosis, anterograde amnesia and dysosmia. Initial brain MRI showed T2 hyperintensity and swelling of isolated bilateral hippocampus, especially CA1 region without any abnormal lesion in other areas. One month later, follow-up brain MRI showed isolated bilateral hippocampal atrophy. This is a meaningful case report because this case differs from other reports of Klüver-Bucy syndrome in humans in that the anatomic abnormalities revealed by MRI were very selective. We report this case because this case is very educative for above reason. Moreover, this report would give us additional information of the relationship between human behavior and limbic system.

Abstract
Relapsing herpes simplex encephalitis (HSE) rarely occurs after acyclovir treatment. We treated a patient with relapsing HSE of the contralateral temporal lobe, resulting in Klüver-Bucy syndrome, after a full-dose acyclovir treatment. This case suggests that physicians should consider sudden behavioral and emotional changes after HSE treatment as a possible indication of relapsing HSE, as well as possible temporal lobe epilepsy, and the need to administer longer acyclovir treatment for select patients.

Abstract
Patients with type I glycogen storage disease (GSD) have poor tolerance to fasting, sometimes less than 3 hours during infancy. Even though most patients are able, as they get older, to tolerate a longer fasting period, they are at permanent risk for fast-induced hypoglycaemia, even in adulthood. Klüver Bucy syndrome, is characterized by psychic blindness (inability to recognize familiar objects), hypermetamorphosis (strong tendency to react to visual stimulus), increased oral exploration, placidity, indiscriminate hyper-sexuality and change in dietary habits. In this case report, we describe the development of Klüver Bucy syndrome in a 28-year-old man with type Ib GSD, following prolonged and severe hypoglycaemia triggered by a common respiratory infection.

Abstract
We describe the case of a 10-year-old girl who developed behavioral changes consistent with Klüver-Bucy Syndrome following Listeria meningoencephalitis at 2½ years of age. MRI at age 4 revealed evidence of diffuse brain atrophy with predominant temporal lobe involvement. Electroencephalograpy at 9½ years of age showed abnormal electrical discharges from the left temporal area. Follow-up MRI with volumetric analysis of the mesial temporal structures at 9 years of age demonstrated decreased hippocampal volume bilaterally. Consistent with the morphological abnormalities, serial neuropsychological evaluations demonstrated expressive and receptive language impairment and an amnestic syndrome that significantly decreased her ability to make new declarative memories and maintain adequate academic progress.

Abstract
The symptoms of Klüver-Bucy syndrome (KBS) include hyperorality, hypersexuality, visual agnosia, hypermetamorphosis and decreased motor or vocal reaction to fear- or anger-provoking stimuli. This syndrome has been associated with a wide variety of neurodegenerative disorders, as well as traumatic, non-traumatic and infectious brain injuries. We report an 11-year-old boy who developed a fairly classical presentation of KBS, presumably in the setting of post-infectious acute disseminated encephalomyelitis (ADEM). This patient's presentation is a reminder of this rare syndrome and extends the clinical manifestations of ADEM, which is a relatively more common condition.

Abstract
We describe a 17-year-old girl with hypersexuality resulting from virilization, the latter a consequence of polycystic ovary syndrome, and we review the literature pertinent to hypersexuality in children and adults. Inappropriate sexual behavior (a common cause of disruption among children who are hospitalized for psychiatric disorders) may be caused either by hypersexuality or by simply ill-regulated behavior: a definition of hypersexuality is proposed that can be applied at the bedside (namely, sexual behaviors or fantasies that have abruptly increased in frequency by comparison with a previous baseline, are of sufficient excessiveness to disrupt expected or usual social, academic, or occupational functioning, or constitute a source of distress), so that this distinction can be made promptly, and we present a differential diagnosis for hypersexuality to direct its evaluation. Virilization does not seem to be a common cause of hypersexuality in children and adolescents, but it should not be overlooked when it does exist. The differential diagnosis of hypersexuality in adults, which we present for comparison, is much larger than it is in children.

Abstract
An 11-year-old boy with epilepsy due to congenital bilateral anterior temporal lobe malformations presented with fluctuating Kluver-Bucy syndrome (KBS). Since the age of 2, he had experienced clusters of three or four daily complex partial seizures over 2-3 days in a month, followed by a seizure-free interval of 3-4 weeks. During the seizure-free period, the patient exhibited hyperorality, sniffing, irritability alternating with placidity, anxiety, unsolicited sexual gestures, and unusual calmness after eating. KBS features escalated up to the onset of the seizure cluster, and remitted after the seizures. Brain MRI revealed bilateral anterior temporal cortical dysplasia with enlarged and dysmorphic amygdalar-hippocampal complex. Brain [(18)F]fluorodeoxyglucose positron emission tomography PET showed bilateral anterior and mesial temporal hypometabolism. Video/EEG monitoring revealed independent right and left temporal lobe seizures. This is the first reported case of KBS due to congenital bitemporal malformations. Also, KBS behavior phenotype in this patient fluctuated, with escalation during the seizure-free period and remission induced by the monthly seizure cluster. This fluctuating pattern could represent forced normalization.

Abstract
Kluver-Bucy syndrome is a rare neurobehavioral condition characterized by visual agnosia, excessive oral tendency, hypermetamorphosis, placidity, altered sexual behaviors, and changes in dietary habits. The authors report a case of Kluver-Bucy syndrome in a 10-year-old boy with non-Hodgkin lymphoma after intratechal methotrexate administration. He was treated by risperidone without any sequels.

Abstract
Kluver-Bucy syndrome is a rare neurobehavioral condition characterized by visual agnosia, excessive oral tendencies, hypermetamorphosis, placidity, altered sexual behavior, and changes in dietary habits. This description of a 14-year-old boy presenting with complete Kluver-Bucy syndrome after Mycoplasma pneumoniae bronchitis is the first such case report. MRI revealed left temporal horn dilation and asymmetry of both temporal lobes. We hypothesize that the pathophysiology of our case is immune-mediated damage by M. pneumoniae resulting in vasculopathy.

Abstract
BACKGROUND The temporal variant of frontotemporal dementia (tvFTD) features asymmetric anterior temporal/amygdala degeneration as well as ventromedial frontal, insular, and inferoposterior temporal involvement. Left temporal atrophy has been linked to loss of semantic knowledge, whereas behavioral symptoms dominate the right temporal variant. OBJECTIVE To investigate the first symptoms and the timing of subsequent symptoms in patients with left versus right tvFTD. METHODS Twenty-six patients with tvFTD were identified. Six had right > left temporal atrophy (right temporal lobe variant [RTLV]) and were matched with six having comparable left > right temporal atrophy (left temporal lobe variant [LTLV]). Clinical records were reviewed to generate individualized symptom chronologies. RESULTS In all patients, first symptoms involved semantics (4/6 LTLV, 1/6 RTLV), behavior (4/6 RTLV, 1/6 LTLV), or both (1 LTLV, 1 RTLV). Semantic loss began with anomia, word-finding difficulties, and repetitive speech, whereas the early behavioral syndrome was characterized by emotional distance, irritability, and disruption of physiologic drives (sleep, appetite, libido). After an average of 3 years, patients developed whichever of the two initial syndromes--semantic or behavioral--that they lacked at onset. A third stage, 5 to 7 years from onset, saw the emergence of disinhibition, compulsions, impaired face recognition, altered food preference, and weight gain. Compulsions in LTLV were directed toward visual, nonverbal stimuli, whereas patients with RTLV were drawn to games with words and symbols. CONCLUSIONS The temporal variant of frontotemporal dementia follows a characteristic cognitive and behavioral progression that suggests early spread from one anterior temporal lobe to the other. Later symptoms implicate ventromedial frontal, insular, and inferoposterior temporal regions, but their precise anatomic correlates await confirmation.

Abstract
We report a 3-year-old patient who presented a secondary acute neurological deterioration clinically characterized by a partial Kluver-Bucy syndrome, 1 month after the onset of herpes simplex encephalitis. This episode is unlikely due to continuation or resumption of cerebral viral replication but might be related to an immune-inflammatory process. In children, postinfectious immune-mediated encephalitis occurring after HSE are usually clinically characterized by choreoathetoid movements. This type of movement disorder was, however, not observed in this patient. On the basis of this case and a review of the literature, we hypothesize the existence of a spectrum of secondary immune-mediated process triggered by herpes simplex virus cerebral infection ranging from asymptomatic cases with diffuse white matter involvement to secondary acute neurological deteriorations with or without extrapyramidal features.

Abstract
This report describes amygdala-kindled seizure development and the post-kindling course in 58 cats (29 males and 29 females), including 40 preadolescents between 2.5 and 6.5 months of age and 18 adults >1 year of age at the beginning of kindling. The results extend previous findings, as follows: (1) Youngest animals (<5.0 months, n=30) are far more likely than older kittens and adults to exhibit spontaneous epilepsy, indexed by seizures that occur >1 h after stimulus-evoked seizures. (2) The youngest animals also exhibit accelerated kindling rates and rapid post-kindling onset of multifocal spontaneous epilepsy with a catastrophic clinical course. The profile includes a variety of EEG and/or clinical seizure manifestations and a progressive increase in the number and density of convulsive seizure clusters. Behavioral sequelae accompany seizure clusters and can range from sensory or motor deficits (visual agnosia, sensory hypersensitivity, atonic episodes, restricted mobility) to social isolation and placidity. (3) Onset of spontaneous epilepsy with developmental deterioration is substantially enhanced by recurrent evoked seizures early in the post-kindling course. The post-kindling progression can be stopped or minimized by suspension of evoked seizure trials and/or by management of frequent spontaneous convulsions (>1 per hour) with anticonvulsants. (4) In older cats, many more evoked seizures are required to generate fewer spontaneous seizures with relatively innocuous behavioral disorders. The findings suggest a 'critical period' in kindled kittens for onset of spontaneous temporal lobe epilepsy with severe behavioral consequences and a favorable prognosis for the young following early detection and intervention.

Abstract
Although there have been many recent advances in research, much work remains to be done in the area of child and adolescent eating disorders. More data are needed regarding the normal development of eating behavior, resilience and risk factors for eating pathology, and treatment studies in children and adolescents. The best studied areas include epidemiology, short-term treatment for bulimia nervosa (BN), and outcome in anorexia nervosa. A case report of the single blind use of repetitive transcranial magnetic stimulation in a patient with BN has been reported, but its safe use in children and adolescents remains to be established.
