Attempts to delineate an immune subtype of schizophrenia have not yet led to the clear identification of potential treatment targets. An unbiased informatic approach at the level of individual immune cytokines and symptoms may reveal organisational structures underlying heterogeneity in schizophrenia, and potential for future therapies. The aim was to determine the network and relative influence of pro- and anti-inflammatory cytokines on depressive, positive, and negative symptoms.

Objectives: Deficits in executive functioning are a common consequence of Traumatic Brain Injury (TBI) and the severity of TBI is known to predict functional outcomes. In this review, the authors examine the ability of three commonly used tests of executive functioning [The Trail Making Test (TMT-B), The Wisconsin Card Sorting Test (WCST), and Verbal Fluency (VF)] to predict domains of function.

Methods: Seven hundred and twenty articles were identified and twenty-four met inclusion criteria (original articles published in English examining an adult TBI population).

The COVID-19 pandemic has highlighted the need for further research evaluating the validity of conducting a battery of neuropsychological assessments virtually compared with face-to-face administration. Previous research has suggested that some neuropsychological assessments yield valid results when administered virtually, however, much of the previous research focused on older adults. To determine the validity of virtually administered neuropsychological tests, 28 healthy participants were assessed using a within-subjects, counter-balanced design.

Background: Evidence suggests that cognitive subtypes exist in schizophrenia that may reflect different neurobiological trajectories. We aimed to identify whether IQ-derived cognitive subtypes are present in early-phase schizophrenia-spectrum disorder and examine their relationship with brain structure and markers of neuroinflammation.

Method: 161 patients with recent-onset schizophrenia spectrum disorder (<5 years) were recruited.

Background: Immune dysfunction has been implicated in negative symptoms of schizophrenia and also in depression. These disorders are frequently co-morbid, with some symptoms such as anhedonia and apathy common to both. The anti-inflammatory agent minocycline may be ineffective in schizophrenia, but more positive effects have been seen in depression.

Background: Carer burden is high during First Episode Psychosis (FEP) and evidence suggests that this is a predictor of poor long-term outcome. However our understanding of factors associated with higher burden is poor. We propose that carers' cultural backgrounds and health belief models will influence their perceived burden of care, over and above that explained by severity of illness.
