Cognitive performance of medicated schizophrenics with tardive dyskinesia.
Twenty schizophrenic patients with tardive dyskinesia and an equal number of matched controls were tested on a novel cognitive task. The task had two components: cued response and spatial memory. Relative to controls, the dyskinetic subjects showed a superior cued response performance but an equal spatial memory ability. We speculate that this selective facilitation may reflect dopaminergic hyperactivity in the dyskinetic group.
