It has occasionally been described in children. In adults Emotional blunting: there is a flat affect and poor response to emotional stimuli placidity. Hyperphagia: there is a strong compulsion to place objects in the mouth, probably to gain oral stimulation and to explore the object to counteract the visual agnosia, rather than due to hunger. Nevertheless, there is bulimia and there will be marked weight gain unless diet is restricted. Actions may include socially inappropriate licking or touching. Visual agnosia: there is an inability to recognise objects or faces visually.

Subdural hygroma  The most common pathologies leading to the development of KBS are head injury and stroke in adults and herpes simplex encephalitis in children. Hence the exact prevalence is difficult to estimate. These pathways are essential for memory and emotional regulation. Temporal lobe seizures may produce a transient state. Visual agnosia results from bilateral ventral temporal ablations and temporal lobectomies. History and Physical In adults: Hyperorality - Socially inappropriate lickings and a strong compulsion to place objects inside the mouth Hypersexuality - Lack of social restraint in terms of sexuality, with inappropriate sexual activity and attempted copulation with inanimate objects Eating disorder - Objects are placed in the mouth and explored with the tongue to counteract visual agnosia.
Bulimia, which is an eating disorder characterized by binge eating, followed by purging, is also markedly seen and may cause weight gain. Placidity - Flat affect and reduced response to emotional stimuli Visual agnosia Psychic blindness - Inability to recognize familiar objects or faces presented visually Placidity, hyperorality, and dietary changes are the most commonly occurring symptoms in KBS. Marked indifference Lack of emotional attachment towards the family Hypersexuality: The frequent holding of genitals Intermittent pelvic thrusts Rubbing of genitals to the bed after lying prone Evaluation The diagnosis of KBS is mainly clinical.
Magnetic resonance imaging of the brain is useful in identifying the extent of temporal lobe damage. Electroencephalogram is also useful to identify seizures originating especially from the temporal lobe. In head injury and other conditions producing a long duration of loss of consciousness, the appropriate staging of the consciousness is possible with the Modified Innsbruck Remission Scale, which includes the Kluver Bucy phase as well.
Most of the treatment focuses on managing the symptoms. The clinical course of the disease varies among the case reports. KBS occurring secondary to epileptic seizures, infections or post-infectious, and traumatic brain injuries may have a better prognosis as many of the damages would be reversible if recognized early and managed appropriately. Complications Due to hyperorality and hypermetamorphosis, the patient may try to put whatever objects he comes across into his mouth, which can be dangerous.
Due to hypersexuality, he may try to engage in sex with others whom he does not even know, leading to criminal procedures against the patient there is no awareness of the diagnosis. Bulimia can cause weight gain, electrolyte disturbance, and poor oral hygiene. They should receive information that situations may arise, which require physical patient restraint.
Enhancing Healthcare Team Outcomes A close interaction between the treating neurologist, psychiatrist, neurosurgeon, and the radiologist is necessary for coming to the final diagnosis of KBS. Careful monitoring of diet is required if they have symptoms consistent with eating disorders.
Staff members, including nurses, should be cognizant about hypersexual behaviors in these patients. The outcomes for these patients are poor; they often require medications to suppress abnormal behavior, and often, physical restraints are needed. Many end up in psychiatric institutions where they remain for life. Questions To access free multiple choice questions on this topic, click here.

Syndrome de Klüver-Bucy
Alternatively known as bilateral temporal lobe disorder, Kluver Bucy syndrome is defined as a rare neurobehavioral disorder with potential human occurrence affecting men and women in the same way that results when there is brain failure from any of diverse factors involving the two sides of the medial temporal lobes. Above all, the brain area which is associated in the pathophysiology of the disorder is the amygdaloid body, a part of the brain which is situated in the subcortical zone of temporal lobe. Affected individuals may suffer from loss of memory, visual distractibility and may exhibit strange behaviors such as improper sexual acts. The human occurrence of the condition was initially recorded by H. Terzian and G. Ore in the year in patients who underwent temporal lobectomy. Kluver Bucy Syndrome Symptoms It is uncommon for humans to present all of the following manifestations of the disease.
