Confrontation naming in parkinsonian patients: post-operative anomia revisited

Forty-three consecutively admitted Parkinsonian patients, of whom over a third had undergone stereotactic surgery about a decade previously, and a small control group were given a confrontation naming task. A number of comparisons were made, under the rubrics of success in naming, types of error and response latency, in an attempt to ascertain whether evidence of post-operative anomia could be detected. No such evidence was found. However, Parkinsonian lesions were shown to exert a constant quantitative effect on performance in the confrontation naming of objects.
