Klüver-Bucy syndrome, which has been reported to occur in up to 70% of cases, is a behavioral abnormality related to temporal lobe function, similar to KBS in animals with bilateral temporal lobe removal. For example, visual awareness is not possible and the inability to recognize the face of a loved one or the self in a mirror. Exploration of objects with the mouth (mouth exploration disorder), which can also manifest as compulsive chewing of gum or smoking, as well as stroking and touching objects in front of the eyes with the hands and excessive and random eating. How is Klüver-Bucy syndrome examined? All patients have fever, abnormal mental behavior, hyperphagia, and changes in eating habits. Case 1 is also associated with mouth exploration (biting) and eating of non-food items. It was accompanied by visual loss of recognition, docility, increased sexual activity, and epilepsy. Both cranial MRI had bilateral temporal lobe damage. Cerebrospinal fluid cell count was mildly elevated (predominantly mononuclear cells), and protein was elevated. EEG: diffuse abnormalities, frontotemporal. The clinical features of herpes simplex encephalitis in Klüver-Bucy syndrome are high fever, behavioral abnormalities, visual loss, calm docility, bulimia, altered eating habits, increased sexual activity, and oral exploration. The diagnosis is based on clinical manifestations, laboratory and imaging studies. Klüver-Bucy syndrome is associated with bilateral temporal lobe damage, and there are six main manifestations of KBS: 1. visual agnosia, inability to distinguish between family members and strangers. 2. 2. Increased oral exploratory behavior, licking, biting, chewing or touching things with the lips. 3. Gluttony or change in eating habits, easy hunger, eating toilet paper, laundry detergent, leaves and other non-food. 4.Over-attention to visual stimuli, showing strong reactions and grabbing, holding or moving whatever they see as the environment changes. 5.Meekness and calmness, loss of normal anger and fear reactions. 6. Abnormal sexual activity, often manifesting as lewdness, attempting to fondle the opposite sex, exposing the body in public places or masturbation. KBS with dementia is common in Pick’s disease, Alzheimer’s disease, and adrenoleukodystrophy, and is often seen in the early stages of Pick’s disease and late stages of Alzheimer’s disease dementia.
