Psychological factors in susceptibility to drug-induced extrapyramidal symptoms
P Levinson, R Malen, G Hogben and H Smith
In an effort to identify nonneurobiologic factors in the susceptibility to
neuroleptic-induced extrapyramidal symptoms (EPS), the EPS response in 20
patients was correlated with field dependence, self-object differentiation,
and premorbid social competence. Only the last proved to be a good
predictor, which suggests that psychosocial factors play a role in a
patient's EPS response.
