Abstract
Cholinergic processes were measured in plasma and red blood cells (RBC) obtained from
patients with mania, depression, and schizophrenia. RBC choline levels were elevated
in manic patients, and lithium treatment led to a further increase. RBC choline transport
was below normal in manic patients, and lithium treatment further reduced choline
transport in addition to reducing the apparent affinity for choline. RBC acetylcholinesterase
was low in depressed and schizophrenic patients, but not in manic patients, whereas
plasma acetylcholinesterase was reduced only in depressed patients. Plasma nonspecific
cholinesterase was below normal in all groups of patients. These results indicate
unique patterns of differences from controls in the cholinergic system in blood samples from patients
with different psychiatric illnesses.
