Abstract
Memory functioning was contrasted in 40 schizophrenic patients with and without tardive
dyskinesia (TD). Visual and verbal memory tests were used to investigate specific
types of impairments. The presence of TD was ascertained using the Abnormal Involuntary
Movement Scale (AIMS). TD patients scored significantly lower than non-TD patients
on two measures of visual learning, though no differences were found for verbal learning
or immediate recall. These results are consistent with previous reports that schizophrenic
patients with TD demonstrate impaired cognitive functioning. They also raise the possibility
that the neurochemical and structural changes underlying TD may produce specific deficits
in memory for visual materials. In addition, a significant relationship was found
between total score on the Brief Psychiatric Rating Scale (BPRS) and performance on
all of the test measures included in the cognitive test battery. This demonstrates
the importance of attending to the overall level of schizophrenic symptomatology when
evaluating results from experimental learning tasks.
