Abstract
BACKGROUND Dynamic functional connectivity (dFC) alterations have been reported in patients with adult-onset and chronic psychosis. We sought to examine whether such abnormalities were also observed in patients with first episode, adolescent-onset psychosis (AOP), in order to rule out potential effects of chronicity and protracted antipsychotic treatment exposure. AOP has been suggested to have less diagnostic specificity compared to psychosis with onset in adulthood and occurs during a period of neurodevelopmental changes in brain functional connections. STUDY DESIGN Seventy-nine patients with first episode, AOP (36 patients with schizophrenia-spectrum disorder, SSD; and 43 with affective psychotic disorder, AF) and 54 healthy controls (HC), aged 10 to 17 years were included. Participants underwent clinical and cognitive assessments and resting-state functional magnetic resonance imaging. Graph-based measures were used to analyze temporal trajectories of dFC, which were compared between patients with SSD, AF, and HC. Within patients, we also tested associations between dFC parameters and clinical variables. STUDY RESULTS Patients with SSD temporally visited the different connectivity states in a less efficient way (reduced global efficiency), visiting fewer nodes (larger temporal modularity, and increased immobility), with a reduction in the metabolic expenditure (cost and leap size), relative to AF and HC (effect sizes: Cohen's D, ranging 0.54 to.91). In youth with AF, these parameters did not differ compared to HC. Connectivity measures were not associated with clinical severity, intelligence, cannabis use, or dose of antipsychotic medication. CONCLUSIONS dFC measures hold potential towards the development of brain-based biomarkers characterizing adolescent-onset SSD.

Abstract
Background First-episode psychosis is common in adolescents and can be distressful to the person experiencing it for the first time. However, there is limited research globally and specifically in Africa about the lived experiences of adolescents admitted into a psychiatric facility for first-episode psychosis. Aim To understand the adolescents' experiences of psychosis and receiving treatment in a psychiatric facility. Setting Adolescent Inpatient Psychiatric Unit, Tygerberg Hospital, Cape Town, South Africa. Methods This was a qualitative study that used purposive sampling to recruit 15 adolescents with first-episode psychosis and admitted to the Adolescent Inpatient Psychiatric Unit, Tygerberg Hospital in Cape Town, South Africa. Individual interviews were audio recorded, transcribed and analysed using thematic analysis consisting of both inductive and deductive coding. Results The participants described negative experiences of their first episode psychosis, provided varying explanations for their first episode psychosis and had the insight that cannabis precipitated their episodes. They described both positive and negative interactions with both the other patients and staff. They did not wish to return to the hospital again following their discharge. Participants stated that they wanted to change their lives, return to school and try to prevent a second episode of psychosis. Conclusion This study provides insights into the lived experiences of adolescents presenting with first-episode psychosis and calls for future research to delve deeper into factors that support or enable recovery among adolescents with psychosis. Contribution The findings of this study call for improving the quality of care in the management of first-episode psychosis in adolescents.

Affective symptom dimensions in early-onset psychosis over time: a principal component factor analysis of the Young Mania Rating Scale and the Hamilton Depression Rating Scale. Eur Child Adolesc Psychiatry 2022; 31:1715-1728.

Abstract
Early-onset psychosis (EOP) is a complex disorder characterized by a wide range of symptoms, including affective symptoms. Our aim was to (1) examine the dimensional structure of affective symptoms in EOP, (2) evaluate the predominance of the clinical dimensions and (3) assess the progression of the clinical dimensions over a 2-year period. STROBE-compliant prospective principal component factor analysis of Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale-21 (HDRS-21) at baseline, 6-months, 1-year and 2-year follow-up. We included 108 EOP individuals (mean age = 15.5 ± 1.8 years, 68.5% male). The factor analysis produced a four-factor model including the following dimensions: mania, depression/anxiety, sleep and psychosis. It explained 47.4% of the total variance at baseline, 60.6% of the total variance at 6-months follow-up, 54.5% of the total variance at 1-year follow-up and 49.5% of the total variance at 2-year follow-up. According to the variance explained, the mania factor was predominant at baseline (17.4%), 6-month follow-up (23.5%) and 2-year follow-up (26.1%), while the depression/anxiety factor was predominant at 1-year follow-up (23.1%). The mania factor was the most stable; 58.3% items that appeared in this factor (with a load > 0.4) at any time point appeared in the same factor at ≥ 3/4 time points. Affective symptoms are frequent and persistent in EOP. Mania seems to be the most predominant and stable affective dimension. However, depression and anxiety may gain predominance with time. A comprehensive evaluation of the dimensional structure and the progression of affective symptoms may offer clinical and therapeutic advantages.

Abstract
Artificial intelligence-based technologies are gradually being applied to psych-iatric research and practice. This paper reviews the primary literature concerning artificial intelligence-assisted psychosis risk screening in adolescents. In terms of the practice of psychosis risk screening, the application of two artificial intelligence-assisted screening methods, chatbot and large-scale social media data analysis, is summarized in detail. Regarding the challenges of psychiatric risk screening, ethical issues constitute the first challenge of psychiatric risk screening through artificial intelligence, which must comply with the four biomedical ethical principles of respect for autonomy, nonmaleficence, beneficence and impartiality such that the development of artificial intelligence can meet the moral and ethical requirements of human beings. By reviewing the pertinent literature concerning current artificial intelligence-assisted adolescent psychosis risk screens, we propose that assuming they meet ethical requirements, there are three directions worth considering in the future development of artificial intelligence-assisted psychosis risk screening in adolescents as follows: nonperceptual real-time artificial intelligence-assisted screening, further reducing the cost of artificial intelligence-assisted screening, and improving the ease of use of artificial intelligence-assisted screening techniques and tools.

Fronto-Parietal Gray Matter Volume Loss Is Associated with Decreased Working Memory Performance in Adolescents with a First Episode of Psychosis. J Clin Med 2021; 10:jcm10173929.

Abstract
Cognitive maturation during adolescence is modulated by brain maturation. However, it is unknown how these processes intertwine in early onset psychosis (EOP). Studies examining longitudinal brain changes and cognitive performance in psychosis lend support for an altered development of high-order cognitive functions, which parallels progressive gray matter (GM) loss over time, particularly in fronto-parietal brain regions. We aimed to assess this relationship in a subsample of 33 adolescents with first-episode EOP and 47 matched controls over 2 years. Backwards stepwise regression analyses were conducted to determine the association and predictive value of longitudinal brain changes over cognitive performance within each group. Fronto-parietal GM volume loss was positively associated with decreased working memory in adolescents with psychosis (frontal left (B = 0.096, p = 0.008); right (B = 0.089, p = 0.015); parietal left (B = 0.119, p = 0.007), right (B = 0.125, p = 0.015)) as a function of age. A particular decrease in frontal left GM volume best predicted a significant amount (22.28%) of the variance of decreased working memory performance over time, accounting for variance in age (14.9%). No such association was found in controls. Our results suggest that during adolescence, EOP individuals seem to follow an abnormal neurodevelopmental trajectory, in which fronto-parietal GM volume reduction is associated with the differential age-related working memory dysfunction in this group.

Abstract
BACKGROUND premorbid IQ (pIQ) and age of onset are predictors of clinical severity and long-term functioning after a first episode of psychosis. However, the additive influence of these variables on clinical, functional, and recovery rates outcomes is largely unknown. METHODS we characterized 255 individuals who have experienced a first episode of psychosis in four a priori defined subgroups based on pIQ (low pIQ < 85; average pIQ ≥ 85) and age of onset (early onset < 18 years; adult onset ≥ 18 years). We conducted clinical and functional assessments at baseline and at two-year follow-up. We calculated symptom remission and recovery rates using the Positive and Negative Symptoms of Schizophrenia Schedule (PANSS) and the Global Assessment Functioning (GAF or Children-GAF). We examined clinical and functional changes with pair-wise comparisons and two-way mixed ANOVA. We built hierarchical lineal and logistic regression models to estimate the predictive value of the independent variables over functioning or recovery rates. RESULTS early-onset patients had more severe positive symptoms and poorer functioning than adult-onset patients. At two-year follow-up, only early-onset with low pIQ and adult-onset with average pIQ subgroups differed consistently, with the former having more negative symptoms (d = 0.59), poorer functioning (d = 0.82), lower remission (61% vs. 81.1%), and clinical recovery (34.1% vs. 62.2%). CONCLUSIONS early-onset individuals with low pIQ may present persistent negative symptoms, lower functioning, and less recovery likelihood at two-year follow-up. Intensive cognitive and functional programs for these individuals merit testing to improve long-term recovery rates in this subgroup.

Role of Executive Function in Response to a Problem Solving Based Psychoeducational Intervention in Adolescents with Psychosis: The PIENSA Trial Revisited. J Clin Med 2019; 8:jcm8122108. [PMID: 31810220 PMCID: PMC6947315 DOI: 10.3390/jcm8122108] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 11/25/2019] [Accepted: 11/26/2019] [Indexed: 02/01/2023] Open
Abstract
An improvement in negative symptoms and a reduction in the number of visits to the emergency department have been reported in a problem solving based psychoeducational group intervention (PE) for adolescents with psychosis relative to a nonstructured group (NS). One of the factors that may play a role on the response to PE treatment is executive function (EF), a crucial cognitive domain for problem-solving performance. We aimed to examine the role of EF in response to PE treatment versus an NS group. We examined the associations between changes in cognition and in clinical/functional variables within each treatment group using Spearman-ranked and partial correlation analyses. A total of 22 individuals (mean age: 16.3) were randomized to PE (N = 10) and NS (N = 12). We found an association between improvements in EF performance and a reduction in positive symptoms (rs = –0.756, p = 0.030 for semantic fluency), reduction in negative symptoms (r = 0.758, p = 0.029 for semantic; rs = –0,733, p = 0.025 for verbal fluency), and reduction in the number of visits to the emergency department (r = –0,743, p = 0.035 for semantic fluency) in the PE group. No associations were found in the NS group. Our results suggest that EF may play a role in the specific improvements observed in the PE group. This may have implications in the development of new areas of clinical intervention focusing on the role of cognitive functioning in response to psychosocial treatments in psychosis.

Abstract
Psychotic disorders are characterized by theory of mind (ToM) impairment. Although ToM undergoes maturational changes throughout adolescence, there is a lack of studies examining ToM performance and its brain functional correlates in individuals with an early onset of psychosis (EOP; onset prior to age 18), and its relationship with age. Twenty-seven individuals with EOP were compared with 41 healthy volunteers using the "Reading-the-Mind-in-the-Eyes" Test, as a measure of ToM performance. A resting-state functional MRI scan was also acquired, in which the default mode network was used to identify areas relevant to ToM processing employing independent component analysis. Group effects revealed worse ToM performance and less intrinsic functional connectivity in the medial prefrontal cortex in EOP relative to healthy volunteers. Group by age interaction revealed age-positive associations in ToM task performance and in intrinsic connectivity in the medial prefrontal cortex in healthy volunteers, which were not present in EOP. Differences in ToM performance were partially mediated by intrinsic functional connectivity in the medial prefrontal cortex. Poorer ToM performance in EOP, coupled with less medial prefrontal cortex connectivity, could be associated with the impact of psychosis during a critical period of development of the social brain, limiting normative age-related maturation.

Reduced frontal slow wave density during sleep in first-episode psychosis. Schizophr Res 2019; 206:318-324. [PMID: 30377012 DOI: 10.1016/j.schres.2018.10.024] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Revised: 10/21/2018] [Accepted: 10/23/2018] [Indexed: 01/29/2023]
Abstract
BACKGROUND Sleep disturbances are commonly reported in psychotic patients and often contribute to the manifestation and severity of their symptoms. Slow waves characterize the deepest stage of NREM sleep, and their occurrence is critical for restorative sleep. Slow wave abnormalities have been reported in patient with schizophrenia, especially when experiencing an exacerbation of psychosis. However, their presence and delineation, with an emphasis on topography, in first-episode psychosis patients (FEP) have not yet been characterized. METHODS We performed sleep high density (hd)-EEG recordings in twenty FEP patients and twenty healthy control subjects (HC). Slow wave activity (SWA) and several other slow wave parameters, e.g. density, amplitude, up- and down-slopes, were calculated at each electrode location and compared across groups. Additionally, the association between slow wave characteristics and clinical symptoms was assessed. RESULTS FEP patients showed a reduction selectively in slow-wave density relative to HC, and this reduction was significant in a large frontal area, including channels overlying the prefrontal cortex. Furthermore, slow wave density was inversely correlated with the severity of FEP positive symptoms. CONCLUSIONS Abnormalities in slow waves are present at the beginning of psychosis, occur in frontal-prefrontal regions that are highly dysfunctional in psychotic patients, and are associated with their positive symptom severity. Building on these findings, future work will help establish the direction of these associations (i.e., if clinical symptoms precede, coincide, or follow SW deficits), which will determine whether ameliorating slow wave sleep deficits is a viable treatment target in early psychosis.

Abstract
BACKGROUND Comorbid substance use, particularly cannabis among adolescents with mental illness, is a major public health concern in developing countries with limited mental health resources. Better understanding of the association between cannabis use and other polysubstance use and early mental illness will provide for more targeted early interventions. AIM This aim of this study was to examine the socio-demographic profile and cannabis use characteristics among adolescents with first-episode early-onset psychosis (EOP) and compare with age-matched and gender-matched adolescents with first-episode non-psychotic mental illness (controls). METHOD Forty-five adolescents with first-episode EOP and 45 controls were assessed using a clinical interview, Positive and Negative Syndrome Scale and World Health Organization Alcohol, Smoking and Substance Involvement Screening test (ASSIST) for substance-related problems. RESULTS There were significant socio-demographic differences among the adolescents with EOP (73% Black, 64% from low family income, 44% from rural areas) compared with controls (24% Black, 53% from low family income, 2% from rural areas). Although there was no difference in lifetime cannabis use, EOP adolescents differed in motivation for cannabis use, had increased current cannabis use (38%, P = 0.01) and more frequent use (52%, P = 0.04) compared with controls (16% current and 18% frequent use). EOP adolescents reported more hazardous use with higher ASSIST mean cannabis-specific involvement scores (EOP 10,2; controls 2,3; P = 0.004). CONCLUSION The differences in socio-demographic variables may reflect the marked disparity in access to mental health care for rural Black youth. Psychotic youth may be more vulnerable to comorbid cannabis-related problems than other mentally ill adolescents. The study highlights the need for early introduction of substance use interventions among adolescents with mental illness.

Abstract
Oxidative stress is a pathophysiological mechanism potentially involved in psychiatric disorders. The objective of this study was to assess the relationship between total antioxidant status (TAS) and the functional status of patients with a first episode of psychosis at the onset of the disease. For this purpose, a sample of 70 patients aged between 9 and 17 years with a first episode of psychosis were followed up for a period of two years. Blood samples were drawn to measure TAS levels at three time points: at baseline, at one year, and at two years. Clinical symptoms and functioning were also assessed at the same time points using various scales. Linear regression analysis was performed to investigate the relationship between TAS and clinical status at each assessment, adjusting for potential confounding factors. The distribution of clinical variables was grouped in different percentiles to assess the dose-response in the relation between clinical variables and TAS. At baseline, patient's score on Children's Global Assessment Scale (CGAS) was directly and significantly associated with TAS with a monotonic increase in percentiles, and surprising this association was reversed after one and two years of follow-up with a monotonic decrease. In summary at the onset of the illness, TAS is positively related to clinical status, whereas as the illness progresses this correlation is reversed and becomes negative. This may be the result of an adaptive response.

Abstract
OBJECTIVES Reliability of schizoaffective disorder (SAD) diagnoses is low in adults but unclear in children and adolescents (CAD). We estimate the test-retest reliability of SAD and its key differential diagnoses (schizophrenia, bipolar disorder, and unipolar depression). METHODS Systematic literature search of Medline, Embase, and PsycInfo for studies on test-retest reliability of SAD, in CAD. Cohen's kappa was extracted from studies. We performed meta-analysis for kappa, including subgroup and sensitivity analysis (PROSPERO protocol: CRD42013006713). RESULTS Out of > 4000 records screened, seven studies were included. We estimated kappa values of 0.27 [95%-CI: 0.07 0.47] for SAD, 0.56 [0.29; 0.83] for schizophrenia, 0.64 [0.55; 0.74] for bipolar disorder, and 0.66 [0.52; 0.81] for unipolar depression. In 5/7 studies kappa of SAD was lower than that of schizophrenia; similar trends emerged for bipolar disorder (4/5) and unipolar depression (2/3). Estimates of positive agreement of SAD diagnoses supported these results. LIMITATIONS The number of studies and patients included is low. CONCLUSIONS The point-estimate of the test-retest reliability of schizoaffective disorder is only fair, and lower than that of its main differential diagnoses. All kappa values under study were lower in children and adolescents samples than those reported for adults. Clinically, schizoaffective disorder should be diagnosed in strict adherence to the operationalized criteria and ought to be re-evaluated regularly. Should larger studies confirm the insufficient reliability of schizoaffective disorder in children and adolescents, the clinical value of the diagnosis is highly doubtful.

Abstract
This study aims to examine regional gray matter (GM) changes over a period of 2 years in patients diagnosed with early-onset first-episode psychosis (EO-FEP), and to identify baseline predictors of abnormalities at the follow-up. Fifty-nine patients with EO-FEP aged 11-17 years were assessed. Magnetic resonance imaging was carried out at admission and 2 years later. Changes over time were assessed with voxel-based morphometry. Fifty-nine patients (34 schizophrenia-SCZ, 15 bipolar disorder-BP, and 10 other psychotic disorders) and 70 healthy controls were assessed. At baseline no differences were found between the EO-FEP groups and control subjects. Over time, SCZ patients presented a larger GM decrease in the orbitofrontal cortex, anterior midline frontal cortex, cingulate, left caudate, and thalamus. BP patients also had a larger GM decrease in the right putamen, right orbitofrontal cortex, and anterior and midline region of the right superior frontal gyrus and left caudate, but with fewer areas showing significant differences than in the comparison between SCZ and controls. In the cross-sectional analysis, only SCZ patients showed differences with respect to controls in some GM areas. Significant baseline predictors of a 2-year reduction in GM were IQ and working memory. EO-FEP patients did not show differences in GM compared to controls at baseline. Both SCZ and BP patients showed a greater decrease in specific areas during the first 2 years. At follow-up, only SCZ patients differed significantly from controls in specific brain areas. The GM reduction was predicted by baseline cognitive variables.

Abstract
OBJECTIVES First-episode psychosis is a frequent emergency department (ED) presentation that may potentially be secondary to an underlying life-threatening HIV-related condition. The aim of this study was to determine the prevalence of HIV infection in patients presenting with a first episode of psychosis. METHODS Medical records of 159 consecutive African, Asian, White and mixed ethnicity patients presenting to a tertiary academic hospital ED with a first episode of psychotic features were prospectively reviewed. RESULTS Of the 159 subjects, 63 (39.6%) were HIV positive. An underlying medical condition was the most common aetiology of psychosis in both HIV-positive (84.2%) and HIV-negative (35.4%) subjects, but was significantly more common in HIV-positive individuals (P < 0.001). Substance-induced psychotic disorders and other primary psychiatric disorders were significantly more common in subjects without HIV infection (P < 0.001 and P < 0.001, respectively). While there were more men in the HIV-negative group (66.7%), gender distribution was almost equal in the HIV-infected group (49.2% male). Overall, as well as in both groups, most subjects were of African race, were unemployed and had not completed high school. CONCLUSIONS Co-occurrence of HIV infection was a frequent finding in first-episode psychotic individuals residing in a high-prevalence HIV setting. These individuals are more likely to have an underlying medical condition precipitating the onset of psychosis, not to have been initiated on antiretroviral therapy and to present with a low CD4 cell count and high HIV viral load.

Abstract
BACKGROUND The study of first episode early onset psychosis can yield many clues to understanding the early development of psychosis and guide interventions to decrease psychosis risk and improve outcome. The aim of the study was to investigate the socio-demographic profile and clinical correlates in early onset psychosis. METHOD Forty-five adolescents with first episode early onset psychosis were assessed by a clinical interview, socio-demographic questionnaire, the Positive and Negative Syndrome Scale (PANSS), Symptom Onset in Schizophrenia (SOS) score, the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test (WHO ASSIST) questionnaire for substance misuse and a urine cannabis level. RESULTS The mean age of the respondents was 15.9 years (SD 1.8, range 10-18 years). Thirty-one (69%) were male. There was a poor recognition of the prodromal period in 22 (49%) patients and caregivers. The mean duration of untreated psychosis (DUP) was 27.2 weeks (SD 56.7). There was a negative correlation between DUP and age of onset (p<0.05). Mean age at onset of psychosis (males 15.7 years, SD 2.2, and females 15.3 years, SD 2.6) and mean age of presentation (males 16.0 years, SD 1.8, and females 15.5 years, SD 1.7) was slightly younger in the females than males, but not statistically significant. A total of 25 (56%) adolescents reported lifetime cannabis use and 24 (96%) were male. CONCLUSION Symptoms of the prodromal period were poorly recognised. The mean DUP suggests a significant delay in treatment and younger children had a longer DUP. The gender differences in presentation (marginal) and substance use (highly significant) suggests that there may be different environmental risk factors for males and females in early onset psychosis or that early onset psychosis is more genetically homogenous and less dependent on environmental triggers.

Abstract
OBJECTIVE Treatment of early-onset schizophrenia spectrum psychosis (EOS) is hampered by limited data on clinical presentation and illness course. We aimed to systematically review the clinical characteristics, diagnostic trajectories, and predictors of illness severity and outcomes of EOS. METHODS We conducted a systematic PubMed, PsycINFO, and Embase literature review including studies published from January 1, 1990 to August 8, 2014 of EOS patients with 1) ≥50% nonaffective psychosis cases; 2) mean age of subjects <19 years; 3) clinical samples recruited through mental health services; 4) cross-sectional or prospective design; 5) ≥20 participants at baseline; 6) standardized/validated diagnostic instruments; and 7) quantitative psychotic symptom frequency or severity data. Exploratory analyses assessed associations among relevant clinical variables. RESULTS Across 35 studies covering 28 independent samples (n = 1506, age = 15.6 years, age at illness onset = 14.5 years, males = 62.3%, schizophrenia-spectrum disorders = 89.0%), the most frequent psychotic symptoms were auditory hallucinations (81.9%), delusions (77.5%; mainly persecutory [48.5%], referential [35.1%], and grandiose [25.5%]), thought disorder (65.5%), bizarre/disorganized behavior (52.8%), and flat or blunted affect/negative symptoms (52.3%/50.4%). Mean baseline Positive and Negative Syndrome Scale (PANSS)-total, positive, and negative symptom scores were 84.5 ± 10.9, 19.3 ± 4.4 and 20.8 ± 2.9. Mean baseline Clinical Global Impressions-Severity and Children's Global Assessment Scale/Global Assessment of Functioning (CGAS/GAF) scores were 5.0 ± 0.7 and 35.5 ± 9.1. Comorbidity was frequent, particularly posttraumatic stress disorder (34.3%), attention-deficit/hyperactivity and/or disruptive behavior disorders (33.5%), and substance abuse/dependence (32.0%). Longer duration of untreated psychosis (DUP) predicted less CGAS/GAF improvement (p < 0.0001), and poor premorbid adjustment and a diagnosis of schizophrenia predicted less PANSS negative symptom improvement (p = 0.0048) at follow-up. Five studies directly comparing early-onset with adult-onset psychosis found longer DUP in EOP samples (18.7 ± 6.2 vs. 5.4 ± 3.1 months, p = 0.0027). CONCLUSIONS EOS patients suffer substantial impairment from significant levels of positive and negative symptoms. Although symptoms and functioning improve significantly over time, pre-/and comorbid conditions are frequent, and longer DUP and poorer premorbid adjustment is associated with poorer illness outcome.

Abstract
The aim of the study was to analyze changes in functional adjustment from childhood to 2 years after the first episode of psychosis (FEP) in patients with early-onset schizophrenia spectrum disorders (SSD) and affective psychoses (AFP) and a good or intermediate level of premorbid adjustment. We followed 106 adolescents (aged 12-17 years) with FEP for 2 years after recruitment. Premorbid adjustment in childhood was assessed in 98 patients with the childhood subscale of the Cannon-Spoor Premorbid Adjustment Scale (c-PAS). Global functioning was assessed 2 years after the FEP with the Children's Global Assessment Scale (c-GAS) or the Global Assessment of Functioning scale (GAF), as appropriate. Functional deterioration was defined as a downward shift in the level of functional adjustment from childhood to 2 years after the FEP. In patients with good or intermediate premorbid adjustment, functional deterioration was observed in 28.2 % (26.5 % of the AFP group, 29.4 % of the SSD group). Longer duration of untreated psychosis (Beta = 0.01; P = 0.01) and higher symptom severity at the FEP, as measured with the Clinical Global Impression Scale (Beta = 1.12; P = 0.02), significantly predicted the presence of functional deterioration, accounting for 21.4 % of the variance. Irrespective of diagnosis (SSD or AFP), almost one-third of adolescents with FEP and good or intermediate premorbid adjustment showed functional deterioration from the premorbid period to 2 years after the FEP.

Abstract
Progressive loss of cortical gray matter (GM) and increase of cerebrospinal fluid (CSF) have been reported in early-onset psychosis (EOP). EOP typically begins during adolescence, a time when developmental brain trajectories differ by gender. This study aimed to determine gender differences in progression of brain changes in this population. A sample of 61 (21 females) adolescents with a first psychotic episode and a matched sample of 70 (23 females) controls underwent both baseline and 2-year follow-up anatomical brain imaging assessments. Regional GM and CSF volumes were obtained using automated methods based on the Talairach's proportional grid system. At baseline, only male patients showed a clear pattern of alterations in the frontal lobe relative to controls (smaller GM and larger CSF volumes). However, parallel longitudinal changes for male and female patients relative to controls were observed, resulting in a common pattern of brain changes across both genders: rate of left frontal lobe GM volume loss was larger in male (-3.8%) and female patients (-4.2%) than in controls (-0.7% males; -0.4% females). The reverse was found for the CSF volume in the left frontal lobe. While the GM and CSF volumes of females with EOP appear to be within the normal range at initial illness onset, our results point to a similar trajectory of increased/accelerated brain changes in both male and female patients with EOP. The pattern of progression of brain changes in psychosis appears to be independent of gender or structural alterations on appearance of psychotic symptoms.

Abstract
OBJECTIVES The purpose of this study was to assess differences in the outcomes of youth with schizophrenia-spectrum disorders (SCZ-S) and psychotic disorder not otherwise specified (PsyNOS) during early antipsychotic treatment. METHODS The study was a prospective, naturalistic, inception cohort study of youth ≤19 years old with SCZ-S (schizophrenia, schizoaffective disorder, schizophreniform disorder) or PsyNOS (PsyNOS, brief psychotic disorder) and ≤24 months of lifetime antipsychotic treatment receiving clinician's choice antipsychotic treatment. Baseline demographic, illness and treatment variables, and effectiveness outcomes were compared at 12 weeks last-observation-carried-forward across SCZ-S and PsyNOS patients, adjusting for significantly different baseline variables. RESULTS Altogether, 130 youth with SCZ-S (n=42) or PsyNOS (n=88), mostly antipsychotic naïve (76.9%), were prescribed risperidone (47.7%), olanzapine (19.2%), aripiprazole (14.6%), quetiapine (11.5%), or ziprasidone (6.9%). Compared with those with PsyNOS, SCZ-S youth were older (16.4±2.1 vs. 14.8±3.2, p=0.0040), and less likely to be Caucasian (19.1% vs. 42.5%, p=0.009). At baseline, SCZ-S patients had significantly higher Clinical Global Impressions-Severity (CGI-S) scores (6.0±0.9 vs. 5.5±0.8, p=0.0018) and lower Children's Global Assessment Scale (CGAS) scores (29.6±9.2 vs. 36.1±8.9, p=0.0002) and were more likely to be in the severely ill CGAS group (i.e., CGAS≤40). SCZ-S and PsyNOS patients did not differ regarding all-cause discontinuation (40.5 vs. 40.3%. p=0.49), discontinuation because of adverse effects (12.2% vs. 12.4%, p=0.97), or nonadherence (29.3% vs. 30.9%, p=0.88), but somewhat more SCZ-S patients discontinued treatment for inefficacy (19.5% vs. 7.4%, p=0.063). CGI-S and CGAS scores improved significantly in both diagnostic groups (p=0.0001, each). Adjusting for baseline differences, PsyNOS patients experienced significantly better CGI-I improvement (CGI-I) scores (p=0.012) and more frequently reached higher categorical CGAS group status (p=0.021) than SCZ-S patients. CONCLUSIONS Both youth with SCZ-S and those with PsyNOS experienced significant improvements with clinician's choice antipsychotic treatment. However, treatment discontinuation was common within 12 weeks, with greater inefficacy-related discontinuation in the SCZ-S group, whereas CGI-I and CGAS score-based improvements were greater in the PsyNOS group.

Abstract
BACKGROUND The affective dimension has scarcely been studied in early-onset psychosis. Our aims were to investigate the prevalence and type of affective symptoms in the prodromal and acute phases of early-onset psychosis and to examine their relationship with suicide. We also sought to establish whether the presence of premorbid antecedents or the presence of affective symptoms during the prodromal and acute phase might predict a later diagnosis of bipolar disorder (BP) or schizophrenia (SZ). METHOD Participants were 95 youths, aged 9-17 years, experiencing a first episode of a psychotic disorder (FEP) according to DSM-IV criteria. Prodromal affective symptoms in the year prior to the onset of full-blown psychosis were assessed by means of the K-SADS. Affective symptoms during the acute episode were evaluated using the Hamilton Depression Rating Scale and the Young Mania Rating Scale. Suicidality was assessed during the acute episode and at 6 and 12 months. RESULTS Half of the patients experienced affective symptoms during the prodrome, with depressive symptoms being the most frequently reported. During the acute episode, 23.2% presented depressive, 41.4% mixed and 18.9% manic symptoms. After logistic regression analysis, only the presence of depressive symptoms was significantly associated with suicidality during the 12 months following the FEP. Neither early premorbid antecedents nor the prevalence or type of affective symptoms during the FEP predicted a diagnosis of BP or SZ at 12 months. However, both depressive and manic prodromal symptoms were associated with a later diagnosis of BP. CONCLUSIONS The FEP of both SZ and BP is preceded by an identifiable prodromal phase. Early detection programs should target young people at clinical risk for the extended psychosis phenotype. The high prevalence of affective symptoms during the early phases of psychosis may encourage clinicians to identify and treat them in order to prevent suicide behaviour.

Abstract
BACKGROUND Earlier age at onset of psychosis (AOP) has been associated with poor social adjustment and clinical outcome. Genetic and environmental factors such as obstetric complications, parental history of psychosis, advanced paternal age at time of birth, low birth weight and gestational age, and use of drugs have been described as bringing AOP forward. This study aims to evaluate the relationship between AOP and these factors in a sample of first episode of psychosis (FEP) patients. METHODS Clinical and sociodemographic data, age at FEP, age of parents at birth, parental history of psychosis, drug-use habits of the mother during pregnancy and of the patient before psychotic onset, and Lewis and Murray obstetric complication scale were obtained from 90 patients with FEP. Statistical analysis was performed by means of Pearson correlations, Chi-square tests, Student T-test analyses and a linear regression model using SPSS version 22. RESULTS Pre-eclampsia, need for incubator at birth, use of forceps, parental history of psychosis, and low birth weight were associated with an earlier AOP. Use of forceps and birth weight are the variables which best predict AOP in FEP. Stimulant drugs, which were mostly used together with cannabis and cocaine, were the only substances associated with an earlier AOP. CONCLUSIONS Our findings are consistent with previous study results and underline the role of the prenatal period in the development of psychosis and the importance of careful monitoring of pregnancy and delivery, especially in cases with familial history.

Abstract
Identifying early-onset schizophrenia spectrum disorders (SSD) at a very early stage remains challenging. To assess the diagnostic predictive value of multiple types of data at the emergence of early-onset first-episode psychosis (FEP), various support vector machine (SVM) classifiers were developed. The data were from a 2-year, prospective, longitudinal study of 81 patients (age 9-17 years) with early-onset FEP and a stable diagnosis during follow-up and 42 age- and sex-matched healthy controls (HC). The input was different combinations of baseline clinical, neuropsychological, magnetic resonance imaging brain volumetric and biochemical data, and the output was the diagnosis at follow-up (SSD vs. non-SSD, SSD vs. HC, and non-SSD vs. HC). Enhanced recursive feature elimination was performed for the SSD vs. non-SSD classifier to select and rank the input variables with the highest predictive value for a diagnostic outcome of SSD. After validation with a test set and considering all baseline variables together, the SSD vs. non-SSD, SSD vs. HC and non-SSD vs. HC classifiers achieved an accuracy of 0.81, 0.99 and 0.99, respectively. Regarding the SSD vs. non-SSD classifier, a combination of baseline clinical variables (severity of negative, disorganized symptoms and hallucinations or poor insight) and neuropsychological variables (impaired attention, motor coordination, and global cognition) showed the highest predictive value for a diagnostic outcome of SSD. Neuroimaging and biochemical variables at baseline did not add to the predictive value. Thus, comprehensive clinical/cognitive assessment remains the most reliable approach for differential diagnosis during early-onset FEP. SVMs may constitute promising multivariate tools in the search for predictors of diagnostic outcome in FEP.

Abstract
Objective To review the metabolic consequences of second-generation antipsychotics in youth and current monitoring and intervention guidelines for optimal treatment. Background Second-generation antipsychotics have largely replaced the use of first-generation antipsychotics in treating psychotic disorders in youth. In addition, there has been a dramatic increase in using these medications to treat a variety of nonpsychotic disorders. These medications have significant metabolic side effects, including weight gain. This raises concern, given the problem of pediatric obesity. Materials and methods A review of current literature looking at prescribing practices and possible reasons for the increased use of second-generation antipsychotics in children and adolescents was conducted. Review of the mechanisms for why youth may be particularly vulnerable to the metabolic consequences (particularly weight gain) was similarly completed. In addition, data supporting the efficacy, rationale, and unique side-effect profile of each individual second-generation drug were evaluated to help inform providers on when and what to prescribe, along with current monitoring practices. The current evidence base for possible interventions regarding the management of antipsychotic-induced weight gain was also evaluated. Results and conclusion On the basis of the literature review, there are several speculated reasons for the increase in prescriptions of second-generation antipsychotics. The choice of antipsychotic for youth should be based upon the disorder being treated along with the unique side-effect profile for the most commonly used second-generation antipsychotics. Monitoring strategies are also individualized to each antipsychotic. The current interventions recommended for antipsychotic-induced weight gain include lifestyle management, switching medication to a drug with a lower propensity for weight gain, and pharmacologic (particularly metformin) treatment.

A longitudinal study on the relationship between duration of untreated psychosis and executive function in early-onset first-episode psychosis. Schizophr Res 2014; 158:126-33. [PMID: 25034759 DOI: 10.1016/j.schres.2014.06.038] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2014] [Revised: 06/23/2014] [Accepted: 06/26/2014] [Indexed: 01/31/2023]
Abstract
BACKGROUND The relationship between duration of untreated psychosis (DUP) and executive function (EF) in patients with first-episode psychosis (FEP) is controversial. We aim to assess the influence of DUP on changes in EF over a 2-year period in subjects with early-onset FEP (first psychotic symptom before age 18) and less than 6 months of positive symptoms. METHODS A total of 66 subjects were included in the study (19 females [28.8%], mean age 16.2 ± 1.6 years). The influence of DUP on changes in EF over the 2-year follow-up (expressed as a composite score of 5 cognitive abilities: attention, working memory, cognitive flexibility, response inhibition, and problem solving) was estimated using a multivariate linear regression model after removing the effect of intelligence quotient and controlling for age, gender, diagnosis, premorbid adjustment, severity of positive and negative symptoms at baseline, global functioning at baseline, and mean daily antipsychotic dosage during follow-up. RESULTS Mean DUP was 65.0 ± 6.9 days (95% confidence interval [CI], 51.2, 78.8). Median DUP was 47.5 days (range 2-180 days). Negative symptoms at baseline was the only variable significantly associated with EF at baseline (10.9% of explained variance [e.v. 10.9%], p=0.007). Only shorter DUP (e.v. 8.7%, p=0.013) and greater severity of baseline negative symptoms (e.v. 10.0%, p=0.008) were significantly associated with greater improvement in EF. CONCLUSIONS In early-onset FEP, shorter DUP was associated with greater improvement in EF over a 2-year follow-up period.

Abstract
INTRODUCTION Recent evidence points to overlapping decreases in cortical thickness and gyrification in the frontal lobe of patients with adult-onset schizophrenia and bipolar disorder with psychotic symptoms, but it is not clear if these findings generalize to patients with a disease onset during adolescence and what may be the mechanisms underlying a decrease in gyrification. METHOD This study analyzed cortical morphology using surface-based morphometry in 92 subjects (age range 11-18 years, 52 healthy controls and 40 adolescents with early-onset first-episode psychosis diagnosed with schizophrenia (n=20) or bipolar disorder with psychotic symptoms (n=20) based on a two year clinical follow up). Average lobar cortical thickness, surface area, gyrification index (GI) and sulcal width were compared between groups, and the relationship between the GI and sulcal width was assessed in the patient group. RESULTS Both patients groups showed decreased cortical thickness and increased sulcal width in the frontal cortex when compared to healthy controls. The schizophrenia subgroup also had increased sulcal width in all other lobes. In the frontal cortex of the combined patient group sulcal width was negatively correlated (r=-0.58, p<0.001) with the GI. CONCLUSIONS In adolescents with schizophrenia and bipolar disorder with psychotic symptoms there is cortical thinning, decreased GI and increased sulcal width of the frontal cortex present at the time of the first psychotic episode. Decreased frontal GI is associated with the widening of the frontal sulci which may reduce sulcal surface area. These results suggest that abnormal growth (or more pronounced shrinkage during adolescence) of the frontal cortex represents a shared endophenotype for psychosis.

Abstract
OBJECTIVES Despite inclusion of adolescent insanity-a concept proposed by Thomas Clouston in late XIX century-into the broader nosological entity of dementia praecox, the uniqueness of early psychosis is still discussed. The aim of the current study is the assessment of course and outcome in the large sample of early-onset psychosis subjects. METHOD Of 299 patients hospitalized in the period 1998-2008 in an adolescent psychiatry ward with schizophrenia spectrum diagnosis 158 completed a follow-up interview. Data concerning current diagnosis, further admissions, current treatment status and occupational and relationship outcome were analyzed after a mean of 8 years of follow-up. RESULTS Mean age at the index admission and the follow-up was 16.6 ± 1.2 and 24.5 ± 3.0 years respectively. After the subsequent discharge almost all subjects (97%) at least briefly continued psychiatric treatment and 75% of patients had been readmitted. Overall diagnostic stability was 42%. For schizophrenia spectrum disorders and schizophrenia diagnostic stability was 72% and 78%, respectively. At the follow-up assessment 119 (77.3%) of the traced subjects declared current psychiatric treatment and 110 (73.3%) were receiving pharmacotherapy. Almost half of the subjects (48%) were employed or studying and more than a third (35.8%) remained in a stable relationship. Different distributions of baseline diagnoses were observed in males and females, and the latter showed a better outcome. CONCLUSION Early-onset psychoses were characterized by limited diagnostic stability, a necessity for further treatment and hospitalizations and significant percentage of unfavorable functional outcomes. Baseline diagnosis of acute and transient psychotic disorders and female gender were associated with an overall better outcome.

Abstract
The objective of the study is to examine the association of baseline total antioxidant status (TAS) and glutathione (GSH) levels with short- and long-term cognitive functioning in patients with early onset first-episode psychosis, comparing affective and non-affective psychoses. We analysed 105 patients with an early onset-first episode psychosis (age 9-17 years) and 97 healthy controls. Blood samples were taken at admission for measurement of TAS and GSH, and cognitive performance was assessed at baseline and at 2years of follow-up. Regression analysis was used to assess the relationship between TAS/GSH levels at baseline and cognitive performance at both time points, controlling for confounders. Baseline TAS and GSH levels were significantly lower in patients than healthy controls. In patients, baseline TAS was positively associated with the global cognition score at baseline (p=0.048) and two years later (p=0.005), while TAS was not associated with cognitive functioning in healthy controls. Further, baseline TAS in patients was specifically associated with the memory domain at baseline and with the memory and attention domains two years later. Stratifying by affective and non-affective psychoses, significant associations were only found between TAS and cognition in the non-affective psychosis group. Baseline GSH levels were not associated with cognitive functioning at either time point in either group. The antioxidant defence capacity in early onset first-episode psychotic patients is directly correlated with global cognition at baseline and at 2years of follow-up, especially in non-affective psychosis.

Abstract
BACKGROUND Schizophrenia is a chronic syndrome of unknown etiology, predominantly defined by signs of psychosis. The onset of the disorder occurs typically in late adolescence or early adulthood. Efforts to study pathophysiological mechanisms in early stages of the disease are crucial in order to prompt intervention. METHODS Case-control study of first-episode psychotic (FEP) patients and matched controls. We recruited 117 patients during the first year after their FEP according to the DSM-IV criteria and recruited 106 gender-, race-, and age-matched controls between September 2010 and June 2011. RESULTS Biochemical studies carried out in peripheral mononuclear blood cells (PMBC) and plasma evidence a significant increase in intracellular components of a main proinflammatory pathway, along with a significant decrease in the anti-inflammatory ones. Multivariate logistic regression analyses identified the expression of inducible isoforms of nitric oxide synthase and cyclooxygenase in PMBC and homocysteine plasma levels as the most reliable potential risk factors and the inhibitor of the inflammatory transcription factor NFκB, IκBα, and the anti-inflammatory prostaglandin 15d-PGJ2 as potential protection factors. DISCUSSION Taken as a whole, the results of this study indicate robust phenotypical differences at the cellular machinery level in PMBC of patients with FEP. Although more scientific evidence is needed, the determination of multiple components of pro- and anti-inflammatory cellular pathways including the activity of nuclear receptors has interesting potential as biological markers and potential risk/protective factors for FEP. Due to its soluble nature, a notable finding in this study is that the anti-inflammatory mediator 15d-PGJ2 might be used as plasmatic biomarker for first episodes of psychosis.

Duration of untreated psychosis predicts functional and clinical outcome in children and adolescents with first-episode psychosis: a 2-year longitudinal study. Schizophr Res 2014; 152:130-8. [PMID: 24332406 DOI: 10.1016/j.schres.2013.11.018] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2013] [Revised: 11/01/2013] [Accepted: 11/12/2013] [Indexed: 11/30/2022]
Abstract
Longer duration of untreated psychosis (DUP) in adult patients with first-episode psychosis (FEP) has been associated with poor clinical and social outcomes. We aimed to estimate the influence of DUP on outcome at 2-year follow-up in subjects with an early-onset (less than 18 years of age) FEP of less than 6 months' duration. A total of 80 subjects (31.3% females, mean age 16.0±1.8 years) were enrolled in the study. The influence of DUP on outcome was estimated using multiple regression models (two linear models for influence of DUP on the C-GAF at 2 years and C-GAF change through the follow-up period, and a logistic model for influence of DUP on 41 PANSS remission at 2 years in schizophrenia patients (n=47)). Mean DUP was 65.3±54.7 days. Median DUP was 49.5 days. For the whole sample (n=80), DUP was the only variable significantly related to C-GAF score at 2-year follow-up (Beta=-0.13, p<0.01), while DUP and premorbid adjustment (Beta=-0.01, p<0.01; and Beta=-0.09, p=0.04, respectively) were the only variables significantly related to C-GAF change. In schizophrenia patients, DUP predicted both C-GAF score at 2 years and C-GAF change, while in patients with affective psychosis (n=22), DUP was unrelated to outcome. Lower baseline C-GAF score (OR=0.91, p<0.01) and shorter DUP (OR=0.98, p=<0.01) were the only variables that significantly predicted clinical remission in schizophrenia patients. In conclusion, longer DUP was associated with lower C-GAF at 2 years, less increase in C-GAF, and lower rates of clinical remission in early-onset FEP. Our findings support the importance of early detection programs, which help shorten DUP.

Abstract
The human cerebral cortex appears to shrink during adolescence. To delineate the dynamic morphological changes involved in this process, 52 healthy male and female adolescents (11-17 years old) were neuroimaged twice using magnetic resonance imaging, approximately 2 years apart. Using a novel morphometric analysis procedure combining the FreeSurfer and BrainVisa image software suites, we quantified global and lobar change in cortical thickness, outer surface area, the gyrification index, the average Euclidean distance between opposing sides of the white matter surface (gyral white matter thickness), the convex ("exposed") part of the outer cortical surface (hull surface area), sulcal length, depth, and width. We found that the cortical surface flattens during adolescence. Flattening was strongest in the frontal and occipital cortices, in which significant sulcal widening and decreased sulcal depth co-occurred. Globally, sulcal widening was associated with cortical thinning and, for the frontal cortex, with loss of surface area. For the other cortical lobes, thinning was related to gyral white matter expansion. The overall flattening of the macrostructural three-dimensional architecture of the human cortex during adolescence thus involves changes in gray matter and effects of the maturation of white matter.

Abstract
OBJECTIVE The Child and Adolescent First-Episode Psychosis Study is a longitudinal study of early-onset first psychotic episodes. This report describes the naturalistic psychopharmacological treatment administered during a 24-month follow-up period, as well as discontinuation rates, reasons for discontinuation, and adverse effects. METHODS The sample comprised 110 patients, aged 9 to 17 years, with a first psychotic episode. Pharmacological treatment, changes, reasons for discontinuation, and the UKU (Udvalg for Kliniske Undersogelser) Side Effect Rating Scale were registered at 6, 12, and 24 months of follow-up. RESULTS Second-generation antipsychotics, especially risperidone, quetiapine, and olanzapine, were the most commonly used. The discontinuation rate was 44.5% at 6 months, 59.1% at 12 months, and 70.9% at 24 months. Discontinuation rates or reasons for discontinuation (adverse reaction, insufficient response, and other) did not differ significantly between antipsychotics. At 6 months, significant differences were found in body mass index increase and body mass index z score increase, which were higher with olanzapine, and in neurological effects, which were higher with risperidone; at 12 and 24 months, these differences were no longer significant. High maintenance rates were found in the clozapine group, although they had higher scores on the autonomic subscale of the UKU. CONCLUSIONS A long follow-up period reveals high discontinuation rates similar to those observed in adults, particularly during the first year. No differences were found between antipsychotics. Differences in adverse effects were found at 6 months but not subsequently after changes in treatment. Clozapine had a high maintenance rate, and its tolerability was comparable to that of other antipsychotics.

Abstract
BACKGROUND Despite the large body of research on premorbid impairments in schizophrenia, studies comparing different early-onset psychoses are scarce. AIMS To examine premorbid impairments in first episodes of early-onset bipolar and schizophrenia disorders. METHOD We compared premorbid adjustment and other premorbid variables such as IQ and developmental abnormalities in a cohort of children and adolescents (N=69) with bipolar disorder (BP) or schizophrenia (SZ) experiencing their first psychotic episode and in a healthy control group (N=91). RESULTS Schizophrenia patients showed more social impairment in childhood than bipolar patients (p<0.05) and healthy controls (p<0.001) and had higher rates of developmental abnormalities (p<0.05) than healthy controls. Between childhood and early adolescence, schizophrenia and bipolar patients showed a greater decline in academic adjustment than healthy controls, more specifically in adaptation to school (p<0.01). CONCLUSIONS Early-onset schizophrenia patients show more early social impairment than early-onset bipolar patients. Intellectual premorbid abnormalities are less specific and probably more linked to early-onset psychosis.

Abstract
BACKGROUND The longitudinal neuropsychological study of first-episode early-onset psychosis (EOP) patients, whose brain maturation is still in progress at the time of illness onset, provides a unique opportunity to compare their cognitive development with that of healthy subjects, in search of specific patterns resulting from the interaction between neurodevelopmental processes and the presence of psychotic disorders. Method Seventy-five first-episode EOP patients (schizophrenia n = 35; bipolar disorder n = 17; other forms of psychosis n = 23) with a mean age of 15.53 years were assessed with a neuropsychological battery that included measures of attention, working memory, memory and executive functions within 6 months following the onset of the first psychotic symptom (baseline) and 2 years later. Psychotic symptoms were assessed at both times with the Positive and Negative Symptom Scale (PANSS). Seventy-nine healthy subjects matched for age and education served as controls. RESULTS EOP patients showed significant cognitive impairment at both baseline and the 2-year follow-up, with no significant differences between diagnostic groups at either time. Both healthy controls and EOP patients improved in all cognitive measures, except for patient working memory. Improvement in patient attention lost significance after controlling for psychotic symptom reduction. No significant time/diagnosis interaction was found among patients (p > 0.405). CONCLUSIONS Cognitive impairment in EOP is already present at the first episode, and cognitive development seems to be arrested early in EOP patients compared to their healthy peers, at least for some cognitive functions. These and previous similar results support the neurodevelopmental hypothesis of psychosis.

Abstract
PURPOSE OF REVIEW We aimed to review literature on the efficacy and tolerability of psychosocial and psychopharmacological interventions in youth with early-onset schizophrenia spectrum disorders (EOS). A rationale for pragmatic psychopharmacology in EOS, including dosing, switching and adverse effect monitoring and management, is provided. RECENT FINDINGS Three randomized controlled trials (RCTs) over the last 8 years demonstrated benefits of psychosocial interventions (i.e. psychoeducation, cognitive remediation, cognitive behavioural therapy) for EOS without clear advantages of one psychosocial treatment over another. Six large, placebo-controlled, short-term RCTs over the last 4 years demonstrated that aripiprazole, olanzapine, paliperidone, quetiapine and risperidone, but not ziprasidone, were superior to placebo. Except for clozapine's superiority in treatment-refractory EOS, efficacy appeared similar across studied first-generation and second-generation antipsychotics, but tolerability varied greatly across individual agents. SUMMARY Antipsychotics are efficacious in the treatment of EOS. Given the lack of efficacy differences between antipsychotics (except for clozapine for treatment-refractory EOS), we propose that tolerability considerations need to guide choice of antipsychotics. Further and longer-term efficacy and effectiveness studies are urgently needed that should also explore pharmacologic and nonpharmacologic augmentation strategies.

Abstract
INTRODUCTION The concept of cognitive reserve (CR) has been defined as individual differences in the efficient utilization of brain networks which allow some people to cope better than others with brain pathology. CR has been developed mainly in the field of aging and dementia after it was observed that there appears to be no direct relationship between the degree of brain pathology and the severity of clinical manifestations of this damage. The present study applies the concept of CR to a sample of children and adolescents with a first episode of schizophrenia, aiming to assess the possible influence of CR on neuropsychological performance after two year follow-up, controlling for the influence of clinical psychopathology. METHODS 35 patients meeting DSM-IV criteria for schizophrenia or schizoaffective disorder (SSD) and 98 healthy controls (HC) matched for age and gender were included. CR was assessed at baseline, taking into account premorbid IQ, educational-occupational level and leisure activities. Clinical and neuropsychological assessments were completed by all patients at two year follow-up. RESULTS The CR proxy was able to predict working memory and attention at two year follow-up. Verbal memory and cognitive flexibility were not predicted by any of the variables included in the regression model. The SSD group obtained lower scores than HC on CR. CR measures correctly classified 79.8% of the sample as being SSD or HC. CONCLUSIONS Lower scores on CR were observed in SSD than in HC and the CR measure correctly classified a high percentage of the sample into the two groups. CR may predict SSD performance on working memory and attention tasks.

Abstract
The early detection and treatment of people at risk for psychosis is currently regarded as a promising strategy in fighting the devastating consequences of psychotic disorders. Currently, the 2 most broadly used sets of at-risk criteria, that is, ultra-high risk (UHR) and basic symptom criteria, were developed mainly in adult samples. We review the data regarding the presence and relevance of at-risk symptoms for psychosis in children and adolescents. The few existing studies suggest that attenuated psychotic symptoms (APS) and brief limited intermittent psychotic symptoms (BLIPS) do have some clinical relevance in young adolescents from the general population. Nevertheless, their differentiation from atypical psychotic symptoms or an emerging schizotypal personality disorder, as well as their stability and predictive accuracy for psychosis, are still unclear. Further, standard interviews for UHR criteria do not define a minimum age for the assessment of APS and BLIPS or guidelines as to when and how to include information from parents. APS and basic symptoms may be predictive of conversion to psychosis in help-seeking young adolescents. Nevertheless, the rate and timing, and thus the required observation time, need further study. Moreover, no study has yet addressed the issue of how to treat children and adolescents presenting with at-risk symptoms and criteria. Further research is urgently needed to examine if current at-risk criteria and approaches have to be tailored to the special needs of children and adolescents. A preliminary rationale for how to deal with at-risk symptoms for psychosis in clinical practice is provided.

Abstract
BACKGROUND Our objective was to determine antioxidant defence activity in healthy controls (HC) and healthy unaffected second-degree relatives of patients with early onset psychosis (HC-FHP), and to assess its relationship with familiar environment measured using the Family Environment Scale (FES). METHODS We included 82 HC and 14 HC-FHP aged between 9 and 17 years. Total antioxidant status, lipid peroxidation, antioxidant enzyme activities and glutathione levels were determined in blood samples. RESULTS There was a significant decrease in the total antioxidant level in the HC-FHP group compared with the HC group (OR = 2.94; p = 0.009), but no between-group differences in the Global Assessment of Functioning (GAF) scale scores. For the FES, the HC-FHP group had significantly higher scores in the cohesion (p = 0.007) and intellectual-cultural dimensions (p=0.025). After adjusting for these two FES dimensions, total antioxidant status remained significantly different between groups (OR = 10.86, p = 0.009). CONCLUSIONS Although causal relationships cannot be assumed, we can state that family environment is not playing a role in inducing oxidative stress in these healthy subjects. It could be hypothesized that families with affected relatives protect themselves from psychosis with positive environmental factors such as cohesion and intellectual-cultural activities.

Abstract
Psychotic symptoms presenting in youth can be clinically complex and require that a child and adolescent psychiatrist use significant skill in making a diagnosis and initiating treatment. There are a number of illnesses to rule out before making a diagnosis of early-onset schizophrenia in particular. Psychosis in youth has significant associated morbidity and places high demands not only on families but also on the medical and educational systems. More effective pharmacologic and nonpharmacologic treatments for psychosis are needed. Nonpharmacologic therapies targeting relatively treatment-resistant domains of dysfunction such as neurocognition are also necessary as adjunctive treatments to our extant pharmacologic agents.

Abstract
Progressive loss of cortical gray matter (GM), as measured by magnetic resonance imaging, has been described early in the course of first-episode psychosis. This study aims to assess the relationship between oxidative balance and progression of cortical GM changes in a multicenter sample of first-episode early-onset psychosis (EOP) patients from baseline to two-year follow-up. A total of 48 patients (13 females, mean age 15.9±1.5 years) and 56 age- and gender-matched healthy controls (19 females, 15.3±1.5 years) were assessed. Magnetic resonance imaging (MRI) scans performed both at the time of the first psychotic episode and 2 years later were used for volumetric measurements of left and right gray matter regions (frontal, parietal, and temporal lobes) and total sulcal cerebrospinal fluid (CSF). Total glutathione (GSH) blood levels were determined at baseline. In patients, after controlling for possible confounding variables, lower baseline GSH levels were significantly associated with greater volume decrease in left frontal (B=0.034, 95% confidence interval (CI): 0.011 to 0.056, r=0.620, p=0.006), parietal (B=0.039, 95% CI: 0.020 to 0.059, r=0.739, p=0.001), temporal (B=0.026, 95% CI: 0.016 to 0.036, r=0.779, p<0.001), and total (B=0.022, 95% CI: 0.014 to 0.031, r=0.803, p<0.001) gray matter, and with greater increase in total CSF (B=-0.560, 95% CI: -0.270 to -0.850, r=-0.722, p=0.001). Controls did not show significant associations between brain volume changes and GSH levels. GSH deficit during the first psychotic episode was related to greater loss of cortical GM two years later in patients with first-episode EOP, suggesting that oxidative damage may contribute to the progressive loss of cortical GM found in patients with first-episode psychosis.

Abstract
BACKGROUND In recent decades, the assessment of neurological soft signs (NSS) in patients with psychosis has become a subject of special interest. The study of the progression of NSS during adolescence will provide valuable information about the role of NSS as endophenotypes or biomarkers and about brain development at a stage in which brain maturation has not yet been completed. METHODS Neurological soft signs were assessed in a sample of 110 first episodes of early-onset psychosis (EOP) and 98 healthy children and adolescents at two different times in a 2-year follow-up period. RESULTS Patients with EOP showed more NSS than controls both at baseline (p < .001) and the 2-year follow-up (p < .001). No differences were found in the number of signs among the different diagnostic subgroups (schizophrenia, bipolar disorder, and other psychoses). When we examined the changes in NSS over the follow-up, the reduction of NSS in the patients was greater than the controls for 'Motor coordination' (p = .032), 'Others' (p < .001), and 'Total score' (p < .001) of the NES. CONCLUSION Despite the greater reduction of NSS in patients than in controls along the follow-up, patients still have more neurological signs than healthy controls; therefore, these signs may be considered a trait marker. NSS do not seem to be specific to schizophrenia as they are present in different EOPs.

Abstract
BACKGROUND Thalamic volume deficits are associated with psychosis but it is unclear whether the volume reduction is uniformly distributed or whether it is more severe in particular thalamic regions. AIMS To quantify whole and regional thalamic volume in males with early-onset psychosis and healthy male controls. METHOD Brain scans were obtained for 80 adolescents: 46 individuals with early-onset psychosis with a duration of positive symptoms less than 6 months and 34 healthy controls. All participants were younger than 19 years. Total thalamic volumes were assessed using FreeSurfer and FSL-FIRST, group comparisons of regional thalamic volumes were studied with a surface-based approach. RESULTS Total thalamic volume was smaller in participants with early-onset psychosis relative to controls. Regional thalamic volume reduction was most significant in the right anterior mediodorsal area and pulvinar. CONCLUSIONS In males with minimally treated early-onset psychosis, thalamic volume deficits may be most pronounced in the anterior mediodorsal and posterior pulvinar regions, adding strength to findings from post-mortem studies in adults with psychosis.

Abstract
The present study aimed to compare the level and pattern of cognitive deficits in patients with early-onset psychoses with an age, gender and IQ matched control group. In order to ensure a representative sample of patients with psychoses, participants with an IQ of less than 70 were included. Forty-eight patients with an onset of psychoses before the age of 16, and 47 age, gender and IQ matched controls without psychoses were recruited. Psychotic symptomatology was assessed using the Schedules for Clinical Assessment to obtain DSM-IV and ICD-10 diagnoses. Positive and negative symptoms were assessed using the Positive and Negative Symptoms Scale. Levels of cognitive function were measured using a comprehensive neuropsychological battery. A pattern of specific impairments was not found, with few significant differences between the two cohorts. However both cohort groups performed lower than age derived norms. Therefore it appears that there are global cognitive deficits rather than specific deficits in early-onset psychoses when compared to normative data, in-line with conclusions of early-onset schizophrenia research, but patients did not have greater deficit than controls when matched on IQ, gender and age, even after excluding participants with IQ less than 70.

Abstract
The goal of the study is to determine the extent of structural brain abnormalities in a multicenter sample of children and adolescents with a recent-onset first episode of psychosis (FEP), compared with a sample of healthy controls. Total brain and lobar volumes and those of gray matter (GM), white matter, and cerebrospinal fluid (CSF) were measured in 92 patients with a FEP and in 94 controls, matched for age, gender, and years of education. Male patients (n = 64) showed several significant differences when compared with controls (n = 61). GM volume in male patients was reduced in the whole brain and in frontal and parietal lobes compared with controls. Total CSF volume and frontal, temporal, and right parietal CSF volumes were also increased in male patients. Within patients, those with a further diagnosis of "schizophrenia" or "other psychosis" showed a pattern similar to the group of all patients relative to controls. However, bipolar patients showed fewer differences relative to controls. In female patients, only the schizophrenia group showed differences relative to controls, in frontal CSF. GM deficit in male patients with a first episode correlated with negative symptoms. Our study suggests that at least part of the GM deficit in children and adolescent-onset schizophrenia and in other psychosis occurs before onset of the first positive symptoms and that, contrary to what has been shown in children-onset schizophrenia, frontal GM deficits are probably present from the first appearance of positive symptoms in children and adolescents.

Abstract
BACKGROUND Only one study has used a prospective method to analyze the diagnostic stability of first psychotic episodes in children and adolescents. The Child and Adolescent First-Episode Psychosis Study (CAFEPS) is a 2-year, prospective longitudinal study of early-onset first episodes of psychosis (EO-FEP). AIM To describe diagnostic stability and the variables related to diagnostic changes. METHODS Participants were 83 patients (aged 9-17 years) with an EO-FEP consecutively attended. They were assessed with a structured interview (Kiddie-Schedule for Affective Disorders and Schizophrenia, Present and Lifetime version) and clinical scales at baseline and after 2 years. RESULTS The global consistency for all diagnoses was 63.9%. The small group of bipolar disorder had high stability (92.31%) as did the group with schizophrenia spectrum disorders (90.00%). Depressive disorder had lower stability (37.50%) and the lowest values were for psychotic disorder not otherwise specified (11.76%) and brief psychotic disorder (0%).The most frequent diagnostic shift was to schizophrenia spectrum and bipolar disorders. One group of patients did not meet the criteria for any diagnosis at follow-up. Independent predictors of change to schizophrenia spectrum disorders were lower scores on the Children's Global Assessment Scale (CGAS) and the Hamilton Depression Rating Scale. Predictors of not having a diagnosis at follow-up were the CGAS and the Strauss-Carpenter Outcome Scale. CONCLUSIONS Global diagnostic stability was 63.9%. Bipolar and schizophrenia spectrum disorders were the most stable diagnoses, while depressive disorder and other psychosis the least stable. Psychosocial functioning at baseline was a good predictor of diagnosis at follow-up. These data show the need for longitudinal follow-up in EO-FEP before a stable diagnosis is reached.

Abstract
BACKGROUND Our objective is to determine the activity of the antioxidant defense system at admission in patients with early onset first psychotic episodes compared with a control group. METHODS Total antioxidant status (TAS) and lipid peroxidation (LOOH) were determined in plasma. Enzyme activities and total glutathione levels were determined in erythrocytes in 102 children and adolescents with a first psychotic episode and 98 healthy controls. RESULTS A decrease in antioxidant defense was found in patients, measured as decreased TAS and glutathione levels. Lipid damage (LOOH) and glutathione peroxidase activity was higher in patients than controls. Our study shows a decrease in the antioxidant defense system in early onset first episode psychotic patients. CONCLUSIONS Glutathione deficit seems to be implicated in psychosis, and may be an important indirect biomarker of oxidative stress in early-onset schizophrenia. Oxidative damage is present in these patients, and may contribute to its pathophysiology.

Abstract
We analyzed the potential influence of family relationships and history of psychiatric disorders on the presentation and course of early psychotic disorders. We recruited 110 subjects aged 9-17 years with a first psychotic episode and 98 matched healthy controls, and followed them for 1 year. Data were collected through clinical interviews and the Parent-Adolescent Communication Inventory. A family history of psychosis-related disorders was more common in patients' families, with a five-fold higher risk for psychoses related disorders than families of healthy controls. If we consider psychoses related disorder in first-degree relatives, the risk is even higher, rising to 15-fold. The families of patients with a first psychotic episode score themselves worse in communication than the families of healthy controls. More problems in communication at baseline correlated with a higher degree of psychopathology and a lower clinical improvement after 12 months of follow-up.

Abstract
BACKGROUND Increasing evidence supports the important role of illness state and individual characteristics in insight. METHODS Insight, as measured with the Scale to Assess Unawareness of Mental Disorder, over the first 2 years of early-onset first-episode psychosis and its correlations with clinical, socio-demographic, cognitive, and structural brain variables are studied. RESULTS (1) insight at 2 years is poorer in schizophrenia spectrum disorders (SSDs) than in subjects with other psychoses; (2) the more severe the psychosis, the worse the insight. In SSD, depressive symptoms, poorer baseline executive functioning, lower IQ, longer duration of untreated psychosis (DUP), and poorer premorbid infancy adjustment are associated with poorer insight; frontal and parietal gray matter (GM) reductions at baseline correlate with worse insight into having psychotic symptoms at 2 years; (3) insight into having a mental disorder (Scale to Assess Unawareness of Mental Disorder [SUMD]1) at 1 year, DUP, and baseline IQ are the most consistent variables explaining different aspects of insight at 2 years in SSD patients. IQ and SUMD1 at 1 year, together with left frontal and parietal GM volumes, explain 80% of the variance of insight into having specific psychotic symptoms in SSD patients (adjusted R(2) = 0.795, F = 15.576, P < .001). CONCLUSION Insight is a complex phenomenon that depends both on severity of psychopathology and also on disease and subject characteristics, such as past adjustment, IQ, DUP, cognitive functioning, frontal and parietal GM volumes, and age, gender, and ethnicity.

Abstract
OBJECTIVE The prevalence of psychiatric disorders in childhood/adolescence is of 10-15%.The most frequent causes of psychiatric emergence attendances in this age are: behavioral disturbances, suicidal behavior, and depression.The objective of this study is to present the most relevant clinical issues and to guide the initial procedures of psychiatric emergencies in childhood/adolescence. METHOD Non-systematic review. RESULTS Relevant clinical issues for psychiatric emergency evaluation of children/adolescents are presented. Clinical presentations are divided in relevant groups of symptoms, due to its frequency and to its impact to patients and their families. Therefore, the following syndromes are presented: aggressive behavior, intoxication, suicidal behavior, psychoses, anxiety disorders, eating disorders, maltreatment against children/adolescents. The initial procedures recommended for each of these conditions are described. CONCLUSION Psychiatric emergencies in childhood/adolescence can be the re-agudization or a first crisis of a psychiatric disorder. The emergency evaluation's objectives are: to identify the diagnosis, the risks for the child/adolescent, the triggering and maintaining factors, and the presence of familiar and social support.

Abstract
AIM To cut down on the time of untreated psychosis it is necessary to know the pathways to care of patients. We designed this study to examine patients' help seeking contacts. There have only been a few studies in developing countries examining the pathways to care, and this research is the first of its kind in Korea focusing on adolescents. METHODS The sample consisted of 18 adolescents aged 15 to 18 years. We evaluated the Comprehensive Assessment of At-Risk Mental States and 'pathway to care' at the initial evaluation of the patient. 'Pathways to care' data was collected via an interview with the patient. In each interview, the prospective description of each participants' help contacts, from the initial suspected psychiatric illness until the first psychiatric help was noted. RESULTS In total, 14 contacts were made among the 18 patients. Of these, the most common contacts were either through a family member, teacher or the Internet. Thirty-three percent of high risk for psychosis adolescents sought help themselves. CONCLUSION Our findings showed that the Internet and family members were the key contacts in as many as 57% of high risk adolescents. In Korea, patients and caregivers both serve important roles in help seeking efforts. It is important for adolescents who are at high risk of psychosis in Korea to have easy access to information in recognizing mental health problems. Therefore, mass in-depth educating and public campaigning are important in recognizing the symptoms of early psychosis and in doing so can reduce the DUP.
