Several screening methods are available for the detection of cognitive disturbances in mental disorders. Screening instruments are economical and easy to apply in everyday clinical practice. Consequently, the assessment of cognitive performance is relevant for therapy and rehabilitation planning, but also for providing realistic job and employment perspectives. showed for depressed patients that the results of a cognitive screening were associated with severity of illness, self-reported cognitive dysfunction and impairment in daily life. The cognitive functional level proved to be a good predictor for the number and quality of social relationships. It is widely accepted that the correlation between cognitive impairment and psychosocial functional level or occupational activity is significantly stronger than between clinical symptoms and functional level or occupational activity. Ĭognitive deficits have considerable prognostic impact. Inconsistent findings were reported on the stability of the described deficits over the course of relatively brief inpatient treatment, with some reports of no improvement in cognitive deficits between admission and discharge, and other reports of demonstrated improvements. Again, deficits in processing speed were the most common. At all seven points of measurement, the cognitive performance of patients with schizophrenia was significantly worse than patients with other disorders. The authors had examined 244 patients diagnosed with schizophrenia, other psychosis or non-psychotic depression over a period of 20 years after index treatment. This is in contrast to the results of Bonner-Jackson et al. Comparing the cognitive performance of patients with psychosis and affective disorders, no differences were found. Deficits in executive function, attentional performance and memory are also described for patients with bipolar disorders and for patients with depressive disorders. It was also observed that executive functions are impaired in psychotic patients. A meta-analysis of patients with psychotic disorders showed deficits in all cognitive areas, especially in the domains of verbal memory and processing speed. Neuropsychological deficits have been reported in psychosis since Kraepelin and are still of high interest. Trial registrationĭRKS00019825 (retrospectively registered on ). The greatest benefit was observed in chronically ill patients with many previous stays. The SCIP appears to have value in routine diagnostic assessments, and in the quantification of improvements in cognitive performance during an inpatient stay. The cluster with chronic patients showed poorer results at admission, but greater improvement and reached the level of the others at discharge. At discharge, improvements were observed, especially on tests with attention and speed components. More than 70% of the SCIP results on admission were pathological. We conducted cluster analysis to identify cognitive subgroups within the clinical sample. After standardization of the test results against a normative sample, we examined the normalized test values in terms of percentages of pathological cognitive performance based on the total SCIP score, and each of the SCIP subscale scores. A total of 529 assessments were completed on admission, and 227 returned for SCIP at the time of discharge. Shortly after admission, and prior to discharge, patients were routinely referred for examination with the SCIP. We recently integrated the SCIP into our routine admission and discharge assessments on two inpatient wards, and we examined the cognitive profiles of patients with psychotic and affective disorders over the course of their admission. The SCIP is a well-evaluated screening instrument for the examination of cognitive performance in psychiatric patients. The detection of cognitive deficits is crucial both for clinical treatment and for predicting the psychosocial functional level in the further course of the disease. Cognitive dysfunction has been reported in acute psychiatric patients for a long time.
