A 2-year longitudinal study of neuropsychological functioning, psychosocial adjustment and rehospitalisation in schizophrenia and major depression.

Neuropsychological functioning turns out to be a rate-limiting factor in psychiatry. However, little is known when comparing neuropsychological and psychosocial functioning in inpatients with schizophrenia or severe depression in their treatment pathways including add-on psychoeducation or the latter combined with cognitive behavioral therapy up to 2-year follow-up. To evaluate this question, we investigated these variables in two randomised controlled trials including 196 patients with DSM-IV schizophrenia and 177 patients with major depression. Outcome measures were assessed in the hospital at pre- and posttreatment and following discharge until 2-year follow-up. We focused on neuropsychological and psychosocial functioning regarding its differences and changes over time in data of two pooled trials. There were significant time effects indicating gains in knowledge about the illness, short and medium-term memory (VLMT) and psychosocial functioning (GAF), however, the latter was the only variable showing a time x study/diagnosis interaction effect at 2-year follow-up, showing significant better outcome in depression compared to schizophrenia. Moderator analysis showed no changes in psychosocial and neuropsychological functioning in schizophrenia and in affective disorders due to age, duration of illness or sex. Looking at the rehospitalisation rates there were no significant differences between both disorders. Both groups treated with psychoeducation or a combination of psychoeducation and CBT improved in neuropsychological and psychosocial functioning as well as knowledge about the illness at 2-year follow-up, however, patients with major depression showed greater gains in psychosocial functioning compared to patients with schizophrenia. Possible implications of these findings were discussed.

Sixth Kraepelin Symposium-Understanding and Treating Cognitive Impairment and Depression in Schizophrenia and Affective Disorders.

The Sixth Kraepelin Symposium was held at the Department of Psychiatry and Psychotherapy, University Hospital, LMU Munich in October 2018, covering reports from 12 working groups (Keith H. Nuechterlein, Ph.D., University of California, Los Angeles; Kim T. Mueser, Ph.D., Center for Psychiatric Rehabilitation, Boston University, U.S.A.; Dominic Dwyer, Ph.D, Hospital LMU, Munich; David Fowler, Ph.D. University of Sussex, Brighton, U.K.; Martin Hautzinger, Ph.D., University of Tübingen; Nikolaos Koutsouleris, M.D., Hospital LMU, Munich; Stephan Leucht, M.D., Technical University Munich, Munich; David Miklowitz, Ph.D., UCLA School of Medicine, Los Angeles. U.S.A.; Cornelius Schüle, M.D., Hospital LMU, Munich; Florian Seemüller. M.D., kbo-Lech-Mangfall Clinics for Psychiatry and Psychotherapy, Garmisch Partenkirchen; Carla Torrent, Ph.D., Institute of Neuroscience, University of Barcelona, Barcelona, Spain.) from the United States and Europe on understanding and treating cognitive impairment and depression in schizophrenia and affective disorders. Current psychological interventions to improve outcome in schizophrenia and affective disorder such as cognitive remediation, illness management, psychoeducational and cognitive therapy were focused on, as were evidence-based psychological and pharmacological treatment options, guidelines for treating cognitive deficits and depression in schizophrenia, Cochrane-meta-analysis of acute therapies, relapse prevention as well as supported withdrawal from medication. Prevention of cognitive dysfunction and symptom exacerbation was approached in terms of machine learning methods to revisit Kraepelin's illness distinctions, application of new strategies in order to increase the rate of social recovery in patients with first-episode psychosis as well as in terms of state of the art psychosocial interventions for bipolar disorder in adolescents. Finally, the dissemination of information to consumers and the contribution to the reduction of stereotypes in psychiatry was also part of the symposiums aims.
