Consistent performance over time of schizophrenic patients on a neuropsychological set of tests
Sammanfattning
Eleven patients with DSM-III-R diagnosis of schizophrenia were re-investigated with neuropsychological tests identical to the tests they were investigated with 18-23 years previously. At the second investigation each patient was interviewed by a psychiatrist. The assessment included history of illness, Brief psychiatric rating scale and Barnes Akathisia rating scale. The results showed that in a majority of the patients the general intelligence ability was stable over time regardless of whether they were below or equal to an age and education matched score. Length of illness, length of medication or psychotic symptoms at the second investigation did not influence the results of the general intelligence ability.
