. In order to predict the outcome of patients with acute neurological symptoms at discharge, the concentration of creatine kinase isoenzyme BB (CK‐BB) was determined by radioimmunoassay in the cerebrospinal fluid (CSF) of 115 consecutive patients. On admission and over the next 3 days the concentration of CK‐BB was significantly increased in patients with brain death and other neurological sequelae compared with those with favourable outcome. There was a variation in time in concentrations of CK‐BB between diseases causing neurological sequelae. Thus, cerebrovascular haemorrhages caused highest concentrations on admission, but cerebral ischaemia due to cardiac arrest caused highest concentrations 3 days after admission. On admission the CK‐BB measurements were highly specific with high predictive value of positive result when distinguishing patients with brain death and other neurological sequelae from those without complications at discharge. However, when distinguishing patients with brain death from those with other neurological sequelae, the test was most specific and had highest predictive value of a positive result 3 days after admission.
