Public Health England, November 2016

This resource is intended for local authority and clinical commissioning groups to identify what types of interventions they should focus on to help the uptake and maintenance of healthy behaviours and promote cognitive health among older adults living in the community.

It is also intended for providers of lifestyle behaviour change programmes to support the development of evidence-informed prevention packages for older adults.

It is produced in a way that makes it accessible to public health managers and practitioners working in the public, private and third sector.

Second-generation antipsychotic effect on cognition in patients with schizophrenia—a meta-analysis of randomized clinical trials

Acta Psychiatrica Scandinavica, 16 January 2015

Objective:
To investigate the effect of second-generation antipsychotics on cognitive function in patients diagnosed with schizophrenia or schizoaffective disorder.

Method:
Multiple-treatments meta-analysis model.

Results:
On cognitive composite score, sertindole was superior to clozapine, effect size (ES) 0.87; 95% CI: 0.12–1.63, quetiapine, ES 0.75; 95% CI: 0.00–1.49, and first-generation antipsychotics (FGAs), ES 0.89; 95% CI: 0.14–1.64. Analyses on each cognitive domain showed clozapine, ES 0.37; 95% CI: 0.00–0.74, olanzapine, ES 0.31; 95%CI: 0.02–0.59, quetiapine, ES 0.34; 95% CI: 0.03–0.64, and FGAs, ES 0.51; 95% CI: 0.18–0.83 performing poorer on verbal working memory than ziprasidone, as well as FGAs performing poorer than risperidone, ES 0.31; 95% CI: 0.04–0.58. On executive function, sertindole performed better than clozapine, ES 0.82; 95% CI: 0.06–1.58, olanzapine, ES 0.81; 95% CI: 0.07–1.55, quetiapine, ES 0.76; 95% CI: 0.02–1.51, ziprasidone, ES 0.90; 95% CI: 0.14–1.67, and FGAs, ES 0.83; 95% CI: 0.08–1.58. On processing speed, FGAs performed poorer than sertindole, ES 0.97; 95% CI: 0.02–1.91, and quetiapine, ES 0.36; 95% CI: 0.01–0.72. On long-term verbal working memory, clozapine performed poorer than olanzapine, ES 0.41; 95% CI: 0.06–0.76. On verbal fluency, FGAs performed poorer than olanzapine, ES 0.26; 95% CI: 0.01–0.50, and clozapine, ES 0.44; 95% CI: 0.06–0.81. Lastly, FGAs, ES 0.41; 95% CI: 0.04–0.78, and clozapine, ES 0.44; 95% CI: 0.05–0.83, performed poorer on visuospatial skill compared to olanzapine.

Conclusion:
The meta-analysis was able to detect some trends in the data analyzed, but did not show any drug having a uniform positive cognitive profile.
