Cholinesterases in primary affective disorders.
Cholinesterase activities were measured in plasma (ChE) and in intact erythrocytes (AChE) in patients suffering from manic-depressive illness, their first degree relatives who were well, and unrelated normal volunteers. All the subjects were in a normal mood state at the time of testing. Plasma cholinesterase activity was found to be significantly lower than normal in bipolar (BP), unipolar (UP), other affective disorder (OA) and well subjects belonging to manic-depressive families. Intact erythrocyte cholinesterase (true cholinesterase) activity was also found to be significantly lower than normal in all the above mentioned patients and their relatives. Half of the BP subjects were on lithium treatment and their cholinesterase activities were similar to those patients not on lithium treatment. The data suggest a significant role of cholinergic mechanisms in the etiology of manic-depressive illness.
