Cognitive deficits are present from the onset of psychosis and are considered a core feature of the disorder. Increasing evidence suggests that cognitive function is associated with inflammatory processes. This study evaluated the association between cognition and inflammatory biomarkers in first-episode psychosis (FEP), in order to identify cognitive phenotypes from inflammatory expression profiles.
A case-control study of 92 FEP patients and 80 matched controls was used. Neurocognitive assessment, including verbal ability, sustained attention, verbal memory, working memory and executive function, was performed. The expression of pro- and anti-inflammatory mediators of the main intracellular inflammatory pathway was measured in peripheral blood mononuclear cells and plasma.
FEP patients performed worse in all cognitive domains compared to controls and had higher expression of pro-inflammatory mediators and lower expression of anti-inflammatory mediators. In the FEP group, cognition and psychopathology were associated with inflammation. Hierarchical regression analysis showed that association between the anti-inflammatory prostaglandin 15d-PGJ2 and sustained attention on one hand, and COX-2 expression and executive function on the other, were statistically significant.
Our study provides evidence for an association between anti-inflammatory biomarkers and cognition in FEP. The identification of a subgroup of patients based on these measures could be useful to guide treatment programmes by providing tools to select a personalized treatment approach, but longitudinal studies are needed before. In the future, establishment of biomarkers linked to cognition would be useful to monitor the course of cognitive impairment, but substantially more data will be required. Determination of IκBα, the inhibitory protein of the pro-inflammatory transcription factor NFκB, could be useful in early phases to assess clinical severity.
Hippocampal abnormalities have been demonstrated in schizophrenia. It is
unclear whether these abnormalities worsen with age, and whether they
affect cognition and function.
To determine whether hippocampal abnormalities in chronic schizophrenia
are associated with age, cognition and socio-occupational function.
Using 3 T magnetic resonance imaging we scanned 100 persons aged 19–82
years: 51 were out-patients with stable schizophrenia at least 2 years
after diagnosis and 49 were healthy volunteers matched for age and
gender. Automated analysis was used to determine hippocampal volume and
There were differential effects of age in the schizophrenia and control
samples on total hippocampal volume (group×age interaction:
F(1,95) = 6.57, P = 0.012), with steeper
age-related reduction in the schizophrenia group. Three-dimensional shape
analysis located the age-related deformations predominantly in the
mid-body of the hippocampus. In the schizophrenia group similar patterns
of morphometric abnormalities were correlated with impaired cognition and
poorer socio-occupational function.
Hippocampal abnormalities are associated with age in people with chronic
schizophrenia, with a steeper decline than in healthy individuals. These
abnormalities are associated with cognitive and functional deficits,
suggesting that hippocampal morphometry may be a biomarker for cognitive
decline in older patients with schizophrenia.
