title: Brain-type creatine phosphokinase serum levels before and after ECT.
abstract: Brain-type creatine phosphokinase isoenzyme (CPK BB) was measured by radioimmunoassay in the serum of 31 depressed patients undergoing bilateral ECT. Samples were taken shortly before and at one hour, two hours, and six hours following ECT. ECT did not cause a significant alteration in serum CPK BB concentration during the six hours following the treatment. Similarly, there was no difference in mean pre-ECT concentration of serum CPK BB between patients receiving the first ECT of their current admission and those receiving subsequent treatments. These findings do not support suggestions that ECT causes alteration in permeability of the blood-brain barrier, nor that it causes detectable brain injury.
