Neurocognitive performance in children aged 9 – 12 years who present putative antecedents of schizophrenia
Publication year: 2010

http://www.sciencedirect.com/science/article/pii/S0920996410013551
Abstract/Results: ABSTRACT:
BACKGROUND:
We previously developed a novel method of identifying children aged 9-12 years who may be at elevated risk of developing schizophrenia and the spectrum disorders because they present a triad of putative antecedents of schizophrenia (ASz). The present study aimed to determine whether ASz children also present neurocognitive deficits that are commonly observed in patients with schizophrenia.
METHODS:
Twenty-eight ASz children and 28 typically-developing (TD) children without the antecedents of schizophrenia completed a battery of neurocognitive tests assessing seven domains of function: General intelligence, scholastic achievement, verbal memory, visual memory, working memory, executive function (EF)-verbal fluency, and EF-inhibition.
RESULTS:
Relative to TD children, the ASz group showed poorer performance on all neurocognitive tests (mean Cohen's d effect size=0.52). In linear regression analyses, group status (ASz vs. TD) significantly predicted scores on the general intelligence, verbal memory, working memory, and EF-inhibition domains (p<0.05). The severity of problems on each of the individual antecedents comprising the antecedent triad did not relate strongly to performance on the neurocognitive domains.
CONCLUSIONS:
Children aged 9-12 years who present multiple antecedents of schizophrenia display poorer neurocognition than healthy peers on several domains showing pronounced deficits in schizophrenia, first-episode psychosis, and youth with prodromal symptoms. Longitudinal follow-up is necessary to determine the extent to which poorer neurocognitive performance is specific to those who develop schizophrenia.

Error-related processing dysfunction in children aged 9-12 years presenting putative antecedents of schizophrenia
Publication year: 2010

http://www.sciencedirect.com/science/article/pii/S0006322309009081
Abstract/Results: ABSTRACT:
BACKGROUND:
Intervention aimed at preventing schizophrenia may be most effective if targeted at specific, but modifiable, functional impairments that present during childhood. We have developed a novel method of screening community samples aged 9 to 12 years to identify children who present a triad of putative antecedents of schizophrenia (ASz), defined as 1) speech and/or motor development lags/problems; 2) internalizing, externalizing, and/or peer-relationship problems in the clinical range; and 3) psychotic-like experiences. This study examined whether ASz children display brain function abnormalities during error processing that are similar to those exhibited by adults with schizophrenia.
METHODS:
Twenty-two ASz children and 26 typically developing (TD) children with no antecedents of schizophrenia completed an error-inducing Go/NoGo task during event-related potential recording. Group differences were examined in the amplitude and latency of four event-related potential components: the initial error-related negativity (ERN) and later error-positivity (Pe) elicited on false-alarm responses to NoGo trials, and the corresponding initial correct response negativity (CRN) and later correct response positivity (Pc) elicited during processing of correct responses to Go trials.
RESULTS:
Relative to TD children, ASz children were characterized by reduced ERN amplitude but unaffected CRN, Pe, and Pc amplitudes. No group differences were observed in the latency of any component.
CONCLUSIONS:
Children presenting a triad of putative antecedents of schizophrenia show error-processing dysfunction mimicking that observed in adults with schizophrenia using the same Go/NoGo paradigm. The ASz children displayed specific early error-processing deficits rather than a generalized deficit in self-monitoring.

Temporal lobe volume abnormalities precede the prodrome: a study of children presenting antecedents of schizophrenia
Publication year: 2013
URL:
http://schizophreniabulletin.oxfordjournals.org/content/39/6/1318
Abstract/Results: ABSTRACT:
Distributed abnormalities of gray matter (GM) and white matter (WM) volume characterize individuals experiencing their first episode of schizophrenia. Regions of abnormality are present already, albeit less extensively, during the prodromal phase of illness. This study aimed to determine whether putatively at-risk children, aged 9–12 years, who present multiple antecedents of schizophrenia (ASz), display GM and WM volume abnormalities relative to typically developing (TD) children presenting no antecedents. Structural magnetic resonance images were acquired for 20 ASz children and 20 TD children matched on age, sex, and IQ. Whole-brain differences in GM and WM volume were determined using voxel-based morphometry. Relative to the TD group, ASz children showed significantly decreased GM volume in the right middle temporal gyrus (MTG) and increased GM volume in the left superior-middle temporal gyri (P < 0.05, cluster correction). WM volume was significantly increased in ASz children relative to TD children in a cluster encompassing the left inferior parietal lobe, occipital lobe, and superior temporal gyrus. Post-hoc analyses indicated that these abnormalities were not limited to ASz children who self-reported auditory hallucinations on questionnaire. Our findings suggest that children aged 9–12 years who present multiple ASz are characterized by abnormalities of GM and WM volume in the temporal lobes, comprising a subset of the regions affected in first-episode schizophrenia and in the prodromal phase of illness. These preliminary findings indicate that structural brain abnormalities associated with schizophrenia may be detected in putatively at-risk, preprodromal children. Prospective studies following the brain development of at-risk children are needed.

Mismatch negativity (MMN) and sensory auditory processing in children aged 9–12 years presenting with putative antecedents of schizophrenia
Publication year: 2013
URL:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3807658/
Abstract/Results: ABSTRACT:
Identification of markers of abnormal brain function in children at-risk of schizophrenia may inform early intervention and prevention programs. Individuals with schizophrenia are characterised by attenuation of MMN amplitude, which indexes automatic auditory sensory processing. The current aim was to examine whether children who may be at increased risk of schizophrenia due to their presenting multiple putative antecedents of schizophrenia (ASz) are similarly characterised by MMN amplitude reductions, relative to typically developing (TD) children. EEG was recorded from 22 ASz and 24 TD children aged 9 to 12 years (matched on age, sex, and IQ) during a passive auditory oddball task (15% duration deviant). ASz children were those presenting: (1) speech and/or motor development lags/problems; (2) social, emotional, or behavioural problems in the clinical range; and (3) psychotic-like experiences. TD children presented no antecedents, and had no family history of a schizophrenia spectrum disorder. MMN amplitude, but not latency, was significantly greater at frontal sites in the ASz group than in the TD group. Although the MMN exhibited by the children at risk of schizophrenia was unlike that of their typically developing peers, it also differed from the reduced MMN amplitude observed in adults with schizophrenia. This may reflect developmental and disease effects in a pre-prodromal phase of psychosis onset. Longitudinal follow-up is necessary to establish the developmental trajectory of MMN in at-risk children.

Misperceptions of facial emotions among youth aged 9-14 years who present multiple antecedents of schizophrenia
Publication year: 2014
URL:
http://www.ncbi.nlm.nih.gov/pubmed/23378011
Abstract/Results: ABSTRACT:
Similar to adults with schizophrenia, youth at high risk for developing schizophrenia present difficulties in recognizing emotions in faces. These difficulties might index vulnerability for schizophrenia and play a role in the development of the illness. Facial emotion recognition (FER) impairments have been implicated in declining social functioning during the prodromal phase of illness and are thus a potential target for early intervention efforts. This study examined 9- to 14-year-old children: 34 children who presented a triad of well-replicated antecedents of schizophrenia (ASz), including motor and/or speech delays, clinically relevant internalizing and/or externalizing problems, and psychotic-like experiences (PLEs), and 34 typically developing (TD) children who presented none of these antecedents. An established FER task (ER40) was used to assess correct recognition of happy, sad, angry, fearful, and neutral expressions, and facial emotion misperception responses were made for each emotion type. Relative to TD children, ASz children presented an overall impairment in FER. Further, ASz children misattributed neutral expressions to face displaying other emotions and also more often mislabeled a neutral expression as sad compared with healthy peers. The inability to accurately discriminate subtle differences in facial emotion and the misinterpretation of neutral expressions as sad may contribute to the initiation and/or persistence of PLEs. Interventions that are effective in teaching adults to recognize emotions in faces could potentially benefit children presenting with antecedents of schizophrenia.

Daily stressors and negative life events in children at elevated risk of developing schizophrenia
Publication year: 2014
URL:
http://bjp.rcpsych.org/content/204/5/354.abstract
Abstract/Results: ABSTRACT:
BACKGROUND:
Psychological stress is implicated in the development of schizophrenia, but little is known about experiences of stress among children at elevated risk for the disorder.
AIMS:
To examine stressor exposure and reactivity in children with different vulnerability profiles for schizophrenia: (a) children presenting multiple antecedents of schizophrenia (ASz group), (b) children with a family history of schizophrenia (FHx group) and (c) typically developing low-risk (TD) children.
METHOD:
Ninety-five children (ASz = 29; FHx = 19; ASz+FHx = 5; TD = 42), identified aged 9-12 years using a community-based screening procedure or as relatives of individuals with schizophrenia, completed questionnaires assessing environmental stressors and psychopathology at age 11-14 years.
RESULTS:
Relative to their typically developing peers, children in the FHx and ASz groups were exposed to a greater number of negative life events and a higher frequency of daily stressors, respectively; and were more distressed by these experiences.
CONCLUSIONS:
Stress exposure and reactivity may constitute useful targets of early intervention for psychosis.

Mismatch negativity (MMN) and sensory auditory processing in children aged 9–12 years presenting with putative antecedents of schizophrenia
Publication year: 2013
URL:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3807658/
Abstract/Results: ABSTRACT:
Identification of markers of abnormal brain function in children at-risk of schizophrenia may inform early intervention and prevention programs. Individuals with schizophrenia are characterised by attenuation of MMN amplitude, which indexes automatic auditory sensory processing. The current aim was to examine whether children who may be at increased risk of schizophrenia due to their presenting multiple putative antecedents of schizophrenia (ASz) are similarly characterised by MMN amplitude reductions, relative to typically developing (TD) children. EEG was recorded from 22 ASz and 24 TD children aged 9 to 12 years (matched on age, sex, and IQ) during a passive auditory oddball task (15% duration deviant). ASz children were those presenting: (1) speech and/or motor development lags/problems; (2) social, emotional, or behavioural problems in the clinical range; and (3) psychotic-like experiences. TD children presented no antecedents, and had no family history of a schizophrenia spectrum disorder. MMN amplitude, but not latency, was significantly greater at frontal sites in the ASz group than in the TD group. Although the MMN exhibited by the children at risk of schizophrenia was unlike that of their typically developing peers, it also differed from the reduced MMN amplitude observed in adults with schizophrenia. This may reflect developmental and disease effects in a pre-prodromal phase of psychosis onset. Longitudinal follow-up is necessary to establish the developmental trajectory of MMN in at-risk children.

Toward earlier identification and preventative intervention in schizophrenia: evidence from the London Child Health and Development Study
Publication year: 2016

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4823320/
Abstract/Results: ABSTRACT:
PURPOSE:
The London Child Health and Development Study (CHADS) is a prospective, longitudinal investigation of children, sampled from the general community aged 9-11 years and assessed biennially, who present premorbid risk markers for schizophrenia. The study aims to characterise developmental trajectories of psychological, cognitive, and biological functioning in at-risk children and identify potential targets for early preventative intervention. This review summarises CHADS findings, discusses these in the context of recent theory regarding aetiology and prevention of schizophrenia, and highlights challenges to be addressed with future research.
METHODS:
We review (1) epidemiological information on the prevalence and correlates of developmental antecedents of schizophrenia in the general child population, (2) evidence of psychosocial, cognitive, and biological dysfunctions in at-risk children presenting multiple antecedents of schizophrenia and at-risk children with a family history of schizophrenia, and (3) related findings from an associated sample of help-seeking children receiving intervention.
RESULTS:
Community-based screening of 9-11-year olds identified ~9 % with a triad of antecedents of schizophrenia [including psychotic-like experiences (PLEs)] who are putatively at-risk of psychosis; these children reported greater exposure and responsivity to stressors, impairments in general intelligence and specific cognitive functions, brain structure and function abnormalities, and neuromotor dysfunction. Preliminary evidence suggests distressing PLEs are a viable target for cognitive-behavioural intervention in at-risk children.
CONCLUSIONS:
Intervention in early, premorbid phases of illness might alleviate current difficulties and avert future schizophrenia using benign treatments. The CHADS programme has identified several markers that may index early pathophysiology and constitute potential targets for preventative intervention.

Trajectories of childhood internalizing and externalizing psychopathology and psychotic-like experiences in adolescence: A prospective population-based cohort study
Publication year: 2016

Abstract/Results: ABSTRACT:
Adolescent internalizing and externalizing psychopathology is strongly associated with adult psychiatric morbidity, including psychotic disorders. This study examined whether internalizing or externalizing trajectories (continuity/discontinuity of symptoms) from middle childhood were associated with adolescent psychotic-like experiences (PLEs). Prospective data were collected from a community sample of 553 children (mean age = 10.4 years; 50% male) and their primary caregivers. Participants completed questionnaire reports of internalizing and externalizing psychopathology and PLEs at baseline, and again approximately 2 years later. Logistic regression was used to examine the association of adolescent PLEs with four trajectories of internalizing and externalizing psychopathology (persistent, incident, remitting, and none), controlling for a range of potential confounders and sampling bias. Significant associations were identified between adolescent PLEs and the incident internalizing (adjusted odds ratio [adj. OR] = 2.96; 95% confidence interval [CI] = 1.60–5.49) and externalizing psychopathology (adj. OR = 2.14; 95% CI = 1.11–4.14) trajectories, as well as the persistent internalizing (adj. OR = 1.90; 95% CI = 1.13–3.18) and externalizing (adj. OR = 1.81, 95% CI = 1.02–3.19) trajectories. Children with remitting psychopathology trajectories were no more likely to present later PLEs than those who never experienced psychopathology. While for many individuals symptoms and illness remit during development without intervention, this study provides important insights regarding potential targets and timing for delivery of early intervention and prevention programs.

Adolescent trajectories of cognition and risk for psychosis
Publication year: 2016

Abstract/Results: ABSTRACT:
BACKGROUND
Impairments in multiple cognitive domains are apparent among youth who later develop schizophrenia, but it has been hypothesized that different impairments might follow distinct developmental courses from childhood into adolescence. The aim of the study was to examine developmental trajectories of cognitive growth during adolescence in youth at-risk for psychosis.
METHODS
104 participants were assessed at approximately 24-month intervals (time 1, aged 9-12 years; time 2, 11-14 years; and time 3,
13-17 years) on measures of scholastic achievement, memory, and executive function. Cognitive development between ages 9-17 years was compared between youth characterized by a triad of wellreplicated developmental antecedents of schizophrenia (ASz, N = 32); youth with a least one affected relative with schizophrenia or schizoaffective disorder (FHx; N = 29); and typically developing youth (TD, N = 45).
RESULTS
longitudinal mixed models for repeated measures data indicated that, between the ages of 9-17 years, ASz and FHx groups (relative to TD youth) displayed static impairments on word reading, numerical operations, verbal working memory, visual memory and some aspects of executive functioning, but dynamically changing patterns of cognitive growth on spelling, verbal memory and verbal fluency subtests.
DISCUSSION
The present study identified two important patterns of cognitive growth among youth at-risk for psychosis that have also been observed premorbidly among individuals with schizophrenia. The stable cognitive deficits observed in this study may represent
more suitable targets for cognitive training interventions than dynamically changing patterns of cognitive growth that appear to reflect developmental plasticity and recuperation.

Adolescent trajectories of motor function and risk for psychosis
Publication year: 2016

http://www.nature.com/public/article-assets/npg/npjschz/abstracts/npjschz20168.pdf
Abstract/Results: ABSTRACT:
BACKGROUND
Evidence indicates that individuals who subsequently develop schizophrenia/ schizophrenia spectrum disorders (SDD) in adulthood display poorer motor function during early and middle childhood than individuals who do not develop these disorders.
However, among individuals who develop schizophrenia/SSD in adulthood, motor dysfunction is not apparent at all stages of childhood development and may reduce with increasing age. Currently, little is known about the developmental trajectories of motor function in adolescence among youth at-risk for the disorder.
METHODS
94 participants were assessed at approximately 24-month intervals (time 1, aged 9-12 years; time 2, 11-14 years; and time 3, 13-17 years) on the Purdue Pegboard assessment, comprising four subtests: dominant hand, non-dominant hand, both hands, assembly subtest. Motor function between ages 9-16 years was compared between youth characterized by a triad of well-replicated developmental antecedents of schizophrenia (ASz, N = 29); youth with a least one affected relative with schizophrenia or schizoaffective disorder (FHx; N = 26); and typically developing youth (TD, N = 42).
RESULTS
Longitudinal mixed models for repeated measures data indicated significant improvements with age in TD youth on the assembly subtest only. Relative to TD youth, FHx children exhibited an early deficit on the dominant hand and both hand subtests which was followed by faster rates of improvement with age, but a stable impairment on the assembly subtest across adolescence. In contrast, compared to the TD group, ASz youth showed an early deficit followed by significant improvements for the assembly subtest, but a stable impairment on the dominant hand and both hand subtests across adolescence.
DISCUSSION
Findings are consistent with existing literature indicating that risk for schizophrenia/SSD is associated with delayed motor development. The motor dysfunction observed in both at-risk groups may reflect cerebellar dysfunction, and provides additional support for a cognitive dysmetria model of schizophrenia.

Cortisol awakening response and diurnal cortisol among children at elevated risk for schizophrenia: Relationship to psychosocial stress and cognition
Publication year: 2014
URL:
https://www.sciencedirect.com/science/article/pii/S0306453014001061?via%3Dihub
Abstract/Results: ABSTRACT:
Abnormal hypothalamic-pituitary-adrenal (HPA) axis function, as indexed by elevated diurnal cortisol levels and/or a blunted cortisol awakening response (CAR), has been observed among patients with first episode psychosis and associated with neurocognitive deficits in this population. However, the extent to which these features precede illness onset is unclear. The current study aimed to determine whether children who are at putatively elevated risk for psychosis because they present multiple antecedents of schizophrenia (ASz), and high-risk children with a family history of illness (FHx), are characterized by abnormal cortisol levels when compared with their typically developing (TD) peers. A further aim was to investigate the extent to which cortisol levels are associated with psychosocial stress and neurocognitive function. Thirty-three ASz children, 22 FHx children, and 40 TD children were identified at age 9-12 years using a novel community-based screening procedure or as relatives of individuals with schizophrenia. All participants were antipsychotic-naive and not currently seeking treatment for their symptoms. At age 11-14 years, participants provided salivary cortisol samples and completed psychosocial stress measures and tests of memory and executive function. Results indicated that FHx children, but not ASz children, were characterized by a blunted CAR relative to their TD peers (effect size = -0.73, p = 0.01) that was not explained by psychosocial stress exposure or by distress relating to these experiences. Neither FHx nor ASz children were characterized by elevated diurnal cortisol. Among both FHx and ASz children, more pronounced HPA axis function abnormalities (i.e., higher diurnal cortisol levels and greater blunting of the CAR) were associated with poorer performance on tests of verbal memory and executive function. These findings support the notion that at least some HPA axis abnormalities described in psychosis precede illness onset, rather than being a subsequent epiphenomenon. We speculate that the blunted CAR may constitute an early (potentially genetically mediated) marker of psychosis vulnerability, whilst elevated diurnal cortisol levels may emerge only proximally to disease onset.

Abstract/Results: Abstract
Poor verbal learning and memory function is well-documented among individuals with schizophrenia and those at clinical high-risk for psychosis. This study aimed to identify these impairments among children aged 9–12 years with different schizophrenia risk profiles (family history or antecedents of schizophrenia, each of higher[H] or lower[L] risk load) relative to typically developing peers. These three groups were recruited via community-screening, and differentiated for analysis into: typically developing children (TD = 45); children who had 1 first- or =2 second-degree affected relatives (FHxH = 16) or one second-degree relative (FHxL = 15); and children presenting multiple replicated antecedents of schizophrenia whose clinical symptoms persisted at 2- and/or 4-year follow-up (ASzH = 16) or remitted during follow-up (ASzL = 16). Verbal learning/memory measures assessed at baseline (age 9–12 years) included: (i) total recall; (ii) trial 1 recall; (iii) learning score; (iv) intrusions; (v) total words lost; and (vi) serial position patterns. Analyses of variance indicated that FHxH and ASzH youth demonstrated impaired total recall compared to TD and ASzL children and lost significantly more words between trials than TD and FHxL children. Learning score was impaired among both FHxH and FHxL relative to TD and ASzL children. Thus, among putatively at-risk children, total words recalled and lost distinguished those with higher risk load (by family history or persistent antecedent symptomology), whereas learning score indexed familial vulnerability. Follow-up of the sample is needed to determine the capacity of verbal learning deficits to predict later illness and provide a potential avenue for early remediation to improve clinical or functional outcomes.
