The concentration of choline in the cerebrospinal fluid (CSF) of patients affected by primary dementia and in red blood cells (RBC) of depressed patients before and after treatment with lithium salts was determined using a chemiluminescent assay. The mean CSF concentration of choline was found to be 60 pmoles/ml (SD = 20 pmoles/ml) and this was lower than values obtained previously by spectrophotometric-colorimetric methods. Mean RBC choline concentrations before and after therapy with lithium salts were 20 nmoles/ml (SD = 16 nmoles/ml and 328 nmoles/ml (SD = 206 nmoles/l) respectively and these are similar to those reported previously (obtained by chemiluminescent and non-chemiluminescent methods).
