[Klüver-Bucy syndrome and primitive motor reflexes after heavy brain trauma (author's transl)].
A 16-year-old physically and mentally retarded male developed a complete Klüver-Bucy syndrome similar to that demonstrated in animal experiments and characterized by so-called psychic blindness, oral tendencies, hypermetamorphosis, emotional disturbance, and hypersexuality after severe brain trauma with loss of consciousness and a transitory hemiplegia. In addition, transitory oral and grasp reflexes were observed. Despite the severity of the clinical symptoms, the patient was able to realize and report on his subjective experience of the reflex and on the instinct-motivated behavior associated with the Klüver-Bucy syndrome. In the case described, two basic behavior patterns could be differentiated, each influencing drive and the abnormally increased sexuality. The first phase of the illness was dominated by relatively constant automatic reactions. These had the character of pre-determined instinctive behavior and were more or less emotionally neutral. In the second phase of the illness, the instinctive behavior became less evident and the patient was able to respond more normally to his sensory-motor impulses. Also, emotional experience such as frustration, pleasure, and displeasure regained their meaning for the patient.
