Mood-independent aberrancies in associative processes in bipolar affective disorder: an apparent stabilizing effect of lithium.
Forty-eight patients from an affective disorders clinic were tested twice with a word association test. They gave significantly fewer repetitions of common responses than did 29 normal controls. This difference was not related to subgroup diagnosis (bipolar I, bipolar II, unipolar, schizoaffective, and cyclothymic personality), to mood state at the time of testing, or to cycling frequency. The total number of repeated responses was directly correlated with serum lithium level (r = 0.44, p less than 0.01, especially in those judged good lithium responders (r = 0.71, p less than 0.05). This finding may reflect a normalizing effect of lithium on associative processes in affective illness.
