Creatine phosphokinase, the MMPI, and psychosis
ME Faulstich, PJ Brantley and CA Barkemeyer
The mean creatine phosphokinase level of 41 psychotic patients was
significantly higher than that of 30 nonpsychotic psychiatric patients, as
were their MMPI paranoia and schizophrenia scores. Their creatine
phosphokinase level was negatively correlated with hysteria and
psychopathic deviance.
