Presence of Klùver-Bucy syndrome as a positive prognostic feature for the remission of traumatic prolonged disturbances of consciousness.
After severe brain injury a prolonged disturbance of consciousness may occur, sometimes with transient apallic syndrome (awakening without awareness of self and surroundings). Klùver-Bucy is described in the literature as a typical post-traumatic remission phase, in which the patients show an increase of oral automatisms and/or of sexual drive. The study describes Klùver-Bucy syndrome as a sign associated with favourable prognosis in the outcome of traumatic disturbances of consciousness in survivors of head trauma. Seventy-seven patients who had suffered severe brain injury due to traffic accidents entered into the study. All had experienced a relatively benign clinical course since they recovered full awareness, that is were able to communicate with their relatives. The occurrence of prolonged coma, of apallic syndrome and of Klùver-Bucy syndrome are related to outcome date in regards to the patient's work and family function at a mean of 32 months later. In particular, the duration of the apallic syndrome (duration of unconsciousness) was significantly correlated with the global outcome of the patients (p < 0.001).[1]References
