Abstract
Background Due to limitations of categorical definitions of mental illness, there is a need for quantitative empirical investigations of the dimensional structure of psychopathology. Using exploratory bifactor methods, this study investigated a comprehensive and representative structure of psychopathology in children to better understand how psychotic-like experiences (PLEs), autism spectrum disorder (ASD) symptoms, impulsivity, and sensitivity to reward and punishment, may be integrated into extant general factor models of psychopathology. Methods We used seven child-report and three parent-report instruments capturing diverse mental health symptoms in 11,185 children aged 9-10 from the Adolescent Brain Cognitive DevelopmentSM (ABCD) Study. We built on previous modeling frameworks by conducting both split sample and full sample factor analytic approaches that harnessed recent methodological advances in bifactor exploratory structural equation modeling (B-ESEM) to examine a wide range of psychopathology measures not previously integrated into a single analysis. Validity of psychopathology dimensions was examined by investigating associations with sex, age, cognition, imaging measures, and medical service usage. Results All four factor analytic models showed excellent fit and similar structure within informant. PLEs loaded most highly onto a general psychopathology factor, suggesting that they may reflect non-specific risk for mental illness. ASD symptoms loaded separately from attention/hyperactivity symptoms. Symptoms of impulsivity and sensitivity to reward and punishment loaded onto specific factors, distinct from externalizing and internalizing factors. All identified factors were associated with clinically relevant risk factors, providing preliminary evidence for their construct validity. Conclusion By integrating diverse child-report and parent-report psychopathology measures for children in the ABCD sample, we deliver data on the quantitative structure of psychopathology for an exceptionally large set of measurements and discuss implications for the field.

Abstract
Introduction Attention Deficit Hyperactivity Disorder (ADHD) affects up to 5% of the population and is characterised by symptoms of impulsivity, hyperactivity and inattention. These symptoms are significantly impairing and carry additional risks for children and adults with ADHD, including negative mental health (e.g. depression), physical health (e.g. obesity) and societal outcomes (e.g. imprisonment, divorce). Very few studies have attempted to synthesise these risks in one publication due to the breadth of evidence published on the adverse outcomes of ADHD. Methods An umbrella review was performed to identify reviews (systematic, meta-analysis and narrative) that investigate the risks arising from having ADHD. We conducted a narrative synthesis of the findings and conducted a quality review of the included publications. Results Upon searching five databases, 16,675 records were identified. Of these, 125 reviews met the criteria for inclusion. A narrative synthesis of these findings highlighted three key domains of risks associated with ADHD: mental health, physical health, social and lifestyle. Most reviews were of good and moderate quality. Discussion This review highlights the many risks associated with having ADHD, beyond its three key symptom domains and the impact of the condition on daily functioning.

Treatment with psychostimulants and atomoxetine in people with psychotic disorders: reassessing the risk of clinical deterioration in a real-world setting. Br J Psychiatry 2024; 224:98-105.

Abstract
BACKGROUND Although attention-deficit hyperactivity disorder (ADHD) is often comorbid with schizophrenia spectrum and other psychotic disorders (SZSPD), concerns about an increased risk of psychotic events have limited its treatment with either psychostimulants or atomoxetine. AIMS To examine whether the risk of hospital admission for psychosis in people with SZSPD was increased during the year following the introduction of such medications compared with the year before. METHOD This was a retrospective cohort study using Quebec (Canada) administrative health registries, including all Quebec residents with a public prescription drug insurance plan and a diagnosis of psychotic disorder, defined by relevant ICD-9 or ICD-10 codes, who initiated either methylphenidate, amphetamines or atomoxetine, between January 2010 and December 2016, in combination with antipsychotic medication. The primary outcome was time to hospital admission for psychosis within 1 year of initiation. State sequence analysis was also used to visualise admission trajectories for psychosis in the year following initiation of these medications, compared with the previous year. RESULTS Out of 2219 individuals, 1589 (71.6%) initiated methylphenidate, 339 (15.3%) amphetamines and 291 (13.1%) atomoxetine during the study period. After adjustment, the risk of hospital admission for psychosis was decreased during the 12 months following the introduction of these medications when used in combination with antipsychotics (adjusted HR = 0.36, 95% CI 0.24-0.54; P < 0.0001). CONCLUSIONS These findings suggest that, in a real-world setting, when used concurrently with antipsychotic medication, methylphenidate, amphetamines and atomoxetine may be safer than generally believed in individuals with psychotic disorders.

Abstract
Research on serious mental disorders, particularly psychosis, has revealed highly variable symptom profiles and developmental trajectories prior to illness-onset. As Dante Cicchetti pointed out decades before the term "transdiagnostic" was widely used, the pathways to psychopathology emerge in a system involving equifinality and multifinality. Like most other psychological disorders, psychosis is associated with multiple domains of risk factors, both genetic and environmental, and there are many transdiagnostic developmental pathways that can lead to psychotic syndromes. In this article, we discuss our current understanding of heterogeneity in the etiology of psychosis and its implications for approaches to conceptualizing etiology and research. We highlight the need for examining risk factors at multiple levels and to increase the emphasis on transdiagnostic developmental trajectories as a key variable associated with etiologic subtypes. This will be increasingly feasible now that large, longitudinal datasets are becoming available and researchers have access to more sophisticated analytic tools, such as machine learning, which can identify more homogenous subtypes with the ultimate goal of enhancing options for treatment and preventive intervention.

Abstract
BACKGROUND Childhood Attention-deficit/hyperactivity disorder (C-ADHD) is a neurodevelopmental disorder, associated with an increased risk of subsequent schizophrenia. The objective of the present study was to determine the prevalence of C-ADHD in schizophrenia and the clinical and cognitive characteristics associated with C-ADHD history in schizophrenia. METHODS 569 subjects with schizophrenia (74 % men, mean age 30.8) were included in ten expert centers at a national level and tested with a comprehensive battery of clinician-rated, patient-reported scales and cognitive tests. C-ADHD was assessed with the WURS (Wender Utah Rating Scale) self-report questionnaire. Multivariate, correlation, and principal component analyses (PCA) were conducted. RESULTS Thirty-nine subjects (N = 39, 6.9 %) were classified in the C-ADHD group. Compared to those without C-ADHD, subjects with C-ADHD were more frequently male, had lower education levels, more severe positive clinical symptoms, more subjective cognitive deficits complaints, and lower medication adherence with small to medium effect sizes. Two cognitive components emerged from the PCA, one component including perceptual reasoning and working memory, and another component including visuospatial search and graphomotor speed, cognitive inhibition/flexibility and central executive functioning. Both components were associated with lower performances in the C-ADHD group. CONCLUSIONS C-ADHD is frequent in schizophrenia and associated with more severe positive symptoms and impaired cognitive performances compared to those without C-ADHD. This suggests that the pathophysiological mechanisms contributing to these disorders may lead to the worsening of the cognitive functioning in patients with both disorders. C-ADHD is a relevant clinical marker to discriminate subgroups of schizophrenia with different profiles for a precision-psychiatry approach.

Abstract
Psychopathological conditions in adolescence and young adulthood often result from an altered neurodevelopment already phenotypically expressed in childhood. Child and adolescent mental health services are ideally placed to intercept in the developmental trajectories of younger adolescents and contribute to the early detection of a risk for psychosis, as proposed by Salazar de Pablo and Arango (2023, Child and Adolescent Mental Health), opening a debate to which we contribute. The early detection of a specific risk for psychosis and of a broader risk for severe mental illness requires an understanding of the clinical staging of psychosis, neurodevelopmental antecedents of severe mental illness and of heterotypic trajectories between childhood phenotypes and adult disorders.

Abstract
BACKGROUND There are now hundreds of systematic reviews on attention deficit hyperactivity disorder (ADHD) of variable quality. To help navigate this literature, we have reviewed systematic reviews on any topic on ADHD. METHODS We searched MEDLINE, PubMed, PsycINFO, Cochrane Library, and Web of Science and performed quality assessment according to the Joanna Briggs Institute Manual for Evidence Synthesis. A total of 231 systematic reviews and meta-analyses met the eligibility criteria. RESULTS The prevalence of ADHD was 7.2% for children and adolescents and 2.5% for adults, though with major uncertainty due to methodological variation in the existing literature. There is evidence for both biological and social risk factors for ADHD, but this evidence is mostly correlational rather than causal due to confounding and reverse causality. There is strong evidence for the efficacy of pharmacological treatment on symptom reduction in the short-term, particularly for stimulants. However, there is limited evidence for the efficacy of pharmacotherapy in mitigating adverse life trajectories such as educational attainment, employment, substance abuse, injuries, suicides, crime, and comorbid mental and somatic conditions. Pharmacotherapy is linked with side effects like disturbed sleep, reduced appetite, and increased blood pressure, but less is known about potential adverse effects after long-term use. Evidence of the efficacy of nonpharmacological treatments is mixed. CONCLUSIONS Despite hundreds of systematic reviews on ADHD, key questions are still unanswered. Evidence gaps remain as to a more accurate prevalence of ADHD, whether documented risk factors are causal, the efficacy of nonpharmacological treatments on any outcomes, and pharmacotherapy in mitigating the adverse outcomes associated with ADHD.

Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are childhood-onset disorders associated with functional and psychosocial impairments that may persist into adulthood, leading to serious personal and societal costs. OBJECTIVE This study aimed to examine the socio-economic difficulties, physical and mental comorbidities, and psycho-social vulnerabilities associated with ADHD, ASD, and their co-occurrence among young adults. METHODS 16 365 families with children born 1997-1999, were involved in the prospective population-based ABIS study (All Babies in Southeast Sweden). A total of 6 233 ABIS young adults answered the questionnaire at the 17-19-year follow-up and were included in this case-control study. Diagnoses of ADHD and ASD from birth up to 17 years of age were obtained from the Swedish National Diagnosis Register. N=182 individuals received a single diagnosis of ADHD, n=78 of ASD, and n=51 received both diagnoses and were considered the co-occurrence group. Multiple multinomial logistic regression analyses were performed. RESULTS In the univariate analyses all three conditions were significantly associated with concentration difficulties, worse health quality, lower socio-economic status, lower faith in the future, less control over life, and lower social support. In the adjusted analyses, individuals with ADHD were almost three-times more likely to have less money compared with their friends (aOR 2.86; p < .001), experienced worse sleep quality (aOR 1.50; p = .043) and concentration difficulties (aOR 1.96; p < .001). ASD group were two-fold more likely to experience concentration difficulties (aOR 2.35; p = .002) and tended not to have faith in the future (aOR .63; p = .055), however, showed lesser risk-taking bahaviours (aOR .40; p < .001). Finally, the co-occurrence was significantly associated with unemployment (aOR 2.64; p = .007) and tended to have a higher risk of autoimmune disorders (aOR 2.41; p = .051), however, showed a 51% lower risk of stomach pain (aOR .49; p = .030). CONCLUSIONS All these conditions significantly deteriorated several areas of life. ADHD/ASD co-occurrence is a heavy burden for health associated with several psychosocial vulnerabilities, that shared a similar morbidity pattern with ADHD although showed less risk cognitive and behavioral profile, similar to the ASD group. Long-term follow-up and support for individuals with these conditions over the life course are crucial.

Abstract
Importance The association between attention-deficit/hyperactivity disorder (ADHD) and schizophrenia has received increased attention; however, evidence on the association between psychiatric comorbidities and subsequent schizophrenia in patients with ADHD is limited. Objective To investigate the risk of being diagnosed with schizophrenia in children and adolescents with ADHD considering the presence of psychiatric comorbidity. Design, Setting, and Participants This was a population-based, retrospective cohort study using the Health Insurance Review and Assessment claims database from January 1, 2007, to December 31, 2019. Participants were children and adolescents aged 5 to 19 years who received an ADHD diagnosis between January 1, 2010, and December 31, 2018, in the nationwide claims data of Korea. Data were analyzed from January 2010 to December 2019. Interventions or Exposures The presence of psychiatric comorbidity was assessed from diagnosis records within 1 year before ADHD diagnosis. Comorbidities were further categorized according to the number of comorbidities and specific comorbid disorders. Main Outcomes and Measures Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% CIs, examining the association between psychiatric comorbidities and the risk of being diagnosed with schizophrenia. Furthermore, the occurrence of psychiatric comorbidity during the follow-up period was explored among patients without psychiatric comorbidity at baseline. Results A total of 211 705 patients with newly diagnosed ADHD were included. A total of 157 272 patients (74.3%) were male, and the age of 5 to 9 years showed the highest distribution (115 081 patients [54.4%]). Patients with psychiatric comorbidity had a significantly higher risk of being diagnosed with schizophrenia than those without (adjusted HR, 2.14; 95% CI, 2.05-2.23). The association between schizophrenia and psychiatric comorbidity became progressively greater with the increasing number of comorbidities. Several individual psychiatric disorders showed an association with development of schizophrenia, with ASD, intellectual disability, tic disorder, depression, and bipolar disorder being the top 5 disorders most associated. Furthermore, 3244 patients (73.8%) without psychiatric comorbidities experienced the emergence of other psychiatric disorders before schizophrenia occurrence. Conclusions and Relevance In this retrospective cohort study involving children and adolescents with ADHD, the presence of psychiatric comorbidity in patients with ADHD was associated with an increased risk of being diagnosed with schizophrenia, with an increased risk observed in multiple comorbidities and a wide variety of comorbidities. These findings highlight the significance of assessing and managing psychiatric comorbidities in patients with ADHD to decrease subsequent schizophrenia risk and allow for early intervention.

Abstract
Objective Psychotic-like experiences (PLEs) are increasingly being recognized as subclinical phenomena that might predict the development of various mental disorders that are not limited to the psychosis spectrum. Accumulating evidence suggests that attention-deficit/hyperactivity disorder (ADHD) and post-traumatic stress disorder (PTSD) are highly comorbid mental disorders. However, their interactive effect on the occurrence of PLEs has not been investigated so far. Therefore, in the present study we aimed to investigate the effect of interaction between ADHD and PTSD symptoms on the level of psychotic-like experiences (PLEs) in the non-clinical sample. Methods The study included 3,000 individuals aged 18-35 years with a negative history of psychiatric treatment. The symptoms of ADHD and PTSD were assessed using self-reports. Results There was a significant association of the interaction between ADHD and PTSD with the level of reporting PLEs. This association remained significant after adjustment for age, gender, the level of education, the current vocational situation, lifetime history of problematic substance use, and depressive symptoms. Post-hoc tests demonstrated significantly higher levels of reporting PLEs in participants with positive screening for both ADHD and PTSD compared to other subgroups of participants. Also, individuals with positive screening for one vulnerability (either ADHD or PTSD) reported significantly higher levels of reporting PLEs compared to those with a negative screening for ADHD and PTSD. In turn, no significant differences between individuals reporting one vulnerability, i.e., between those with positive screening for ADHD and those with positive screening for PTSD, were observed. Conclusion Findings from the present study imply that both PTSD and ADHD symptoms the interaction effect on the level of reporting PLEs that might be of importance for early intervention strategies. However, observed associations require replication in clinical samples.

Abstract
INTRODUCTION The data suggests that in children and adolescents, bipolar disorder (BD) and attention deficit hyperactivity disorder (ADHD) may be strongly correlated. Even though drugs for ADHD and BD are largely accepted, there is relatively little research on the management of comorbidity in children and adolescents, particularly in terms of safety. We provide a synthesis of these findings because one hasn't been made yet. AREAS COVERED As a primary outcome, we wanted to determine whether stimulant or non-stimulant treatment of children and adolescents with ADHD and comorbid BD was effective. As a secondary outcome, we wanted to determine tolerability, especially the risk of mood switch. EXPERT OPINION The findings of this systematic review suggest that methylphenidate, when used with a mood stabilizer, may be safe and not significantly increase the risk of a manic switch or psychotic symptoms when used to treat ADHD that co-occurs with a BD. In situations where stimulants are ineffective or have low tolerance, atomoxetine also seems to be a good alternative, and also in cases of co-morbid anxiety, oppositional defiant disorder, conduct disorders, ICT disorders, and substance use disorders. Additional research with a higher level of evidence is necessary to corroborate these preliminary findings.

Abstract
BACKGROUND Psychotic-like experiences (PLEs) are associated with a variety of psychopathological symptoms. However, it remains unknown which dimensions of psychopathology are most closely related to the occurrence of PLEs. In this study, we aimed to analyze the association of PLEs with various domains of psychopathology. METHODS A total of 1100 nonclinical adults (aged 18-35 years, 51.4% females) with a negative history of psychiatric treatment were surveyed. Assessment of psychopathology was performed using self-reports. Symptoms associated with PLEs were explored as continuous variables and based on clinically relevant thresholds using two separate network analyses. RESULTS In both network analyses, PLEs were directly connected to obsessive-compulsive disorder (OCD) symptoms, manic symptoms, depressive symptoms, and attention-deficit/hyperactivity disorder (ADHD) symptoms. Anxiety symptoms were associated with PLEs only in the network based on threshold scores. Importantly, edge weight for the connection of PLEs and OCD symptoms was significantly higher compared to edge weights of all other direct connections of PLEs with psychopathology in both networks. Edge weight for the connection between PLEs and manic symptoms was significantly higher compared to edge weights for direct connections of PLEs with depressive and ADHD symptoms in the network based on continuous scores of psychopathological symptoms. Edge weights of direct connections of PLEs with depressive, anxiety, and ADHD symptoms did not differ significantly in both networks. CONCLUSIONS Our findings indicate that PLEs are associated with multiple domains of psychopathology. However, these phenomena are most strongly associated with OCD symptoms regardless of their severity threshold.

Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) is a lifespan neurodevelopmental condition resulting from complex interactions between genetic and environmental risk factors. There is evidence that ADHD is associated with other mental disorders, but it remains unclear whether and in what way a causal relationship exists. OBJECTIVE To investigate the direct and indirect causal paths between ADHD and seven common mental disorders. METHODS Two-sample network Mendelian randomisation analysis was performed to identify psychiatric disorders causally related to ADHD. Total and direct effects were estimated in an univariable and multivariable setting, respectively. Robustness of results was ensured in three ways: a range of pleiotropy-robust methods, an iterative approach identifying and excluding outliers, and use of up to two genome-wide association studies per outcome to replicate results and calculate subsequently pooled meta-estimates. RESULTS Genetic liability to ADHD was independently associated with the risk of anorexia nervosa (OR 1.28 (95% CI 1.11 to 1.47); p=0.001). A bidirectional association was found with major depressive disorder (OR 1.09 (95% CI 1.03 to 1.15); p=0.003 in the forward direction and OR 1.76 (95% CI 1.50 to 2.06); p=4×10-12 in the reverse direction). Moreover, after adjustment for major depression disorder, a direct association with both suicide attempt (OR 1.30 (95% CI 1.16 to 1.547); p=2×10-5) and post-traumatic stress disorder (OR 1.18 (95% CI 1.05 to 1.33); p=0.007) was observed. There was no evidence of a relationship with anxiety, bipolar disorder or schizophrenia. CONCLUSIONS This study suggests that ADHD is an independent risk factor for a number of common psychiatric disorders. CLINICAL IMPLICATIONS The risk of comorbid psychiatric disorders in individuals with ADHD needs to be considered both in diagnosis and treatment.

Abstract
Background The Swanson Nolan, and Pelham scale version IV (SNAP-IV) is the most critical tool for ADHD screening and diagnosis, which has two scoring methods. ADHD requires symptom assessment in multiple scenarios, and parent and teacher reports are indispensable for diagnosing ADHD. But the differences of assessment results from fathers, mothers and teachers, and the consistency of results from different scoring methods are unknown. Therefore, we carried out this study to understand the differences in the scores of fathers, mothers and teachers using SNAP-IV for children with ADHD and to explore the differences in scoring results under different scoring methods. Methods The SNAP-IV scale and Demographics Questionnaire and Familiarity Index were used to survey fathers, mothers and head teachers. Measurement data are expressed as the mean ± standard deviation (x ± s). The enumeration data were described by frequency and percentage. ANOVA was used to compare group differences in mothers', fathers', and teachers' mean SNAP-IV scores. The Bonferroni method was used for post hoc multiple comparison tests. Cochran's Q test was used to compare the differences in the abnormal rate of SNAP-IV score results of mothers, fathers and teachers. Dunn's test was used for post hoc multiple comparison tests. Results There were differences in scores among the three groups, and the differences showed inconsistent trends across the different subscales. Differences between groups were calculated again with familiarity as a control variable. The results showed the familiarity of parents and teachers with the patients did not affect the differences in their scores. The evaluation results were different under two assessment methods. Conclusion Results concluded that fathers did not appear to be an appropriate candidate for evaluation. When using the SNAP-V for assessment, it should be comprehensively considered from both the scorer and symptom dimensions.

Abstract
OBJECTIVE Few studies have investigated the parental risk of major psychiatric disorders among patients with comorbid autism spectrum disorder and attention deficit hyperactivity disorder. This study examined the differences in such risk among patients with autism spectrum disorder-only, with attention deficit hyperactivity disorder-only and both conditions. METHODS Between 2001 and 2011, we enrolled 132,624 patients with autism spectrum disorder or attention deficit hyperactivity disorder and 1:10 matched controls for age, sex and demographics from the National Health Insurance Database of Taiwan. Poisson regression models were used to examine the risk of five major psychiatric disorders in the patients' parents compared with those of the controls, including schizophrenia, bipolar disorder, major depressive disorder, alcohol use disorder, and substance use disorder. Patients were classified into the autism spectrum disorder-only, attention deficit hyperactivity disorder-only and dual-diagnosis groups. RESULTS The parents of attention deficit hyperactivity disorder-only and dual-diagnosis groups had a higher likelihood to be diagnosed with (odds ratios [95% confidence intervals]) schizophrenia (attention deficit hyperactivity disorder: 1.48 [1.39, 1.57]; dual: 1.79 [1.45, 1.20]), bipolar disorder (attention deficit hyperactivity disorder: 1.91 [1.82, 2.01]; dual: 1.81 [1.51, 2.17]), major depressive disorder (attention deficit hyperactivity disorder: 1.94 [1.89, 2.00]; dual: 1.99 [1.81, 2.20]), alcohol use disorder (attention deficit hyperactivity disorder: 1.39 [1.33, 1.45]; dual: 1.20 [1.01, 1.42]) and substance use disorder (attention deficit hyperactivity disorder: 1.66 [1.59, 1.73]; dual: 1.34 [1.13, 1.58]) than the controls. In contrast, the parents of autism spectrum disorder-only group had a higher likelihood to be diagnosed with schizophrenia (1.77 [1.46, 2.15]) and major depressive disorder (1.45 [1.32, 1.61]) and a lower likelihood to be diagnosed with alcohol use disorder (0.68 [0.55, 0.84]) than the controls. CONCLUSION The autism spectrum disorder-only group had a different parental incidence of major psychiatric disorders than the attention deficit hyperactivity disorder-only and dual-diagnosis groups. Our findings have implications for clinical practice and future genetic research.

Abstract
BACKGROUND Previous Scandinavian studies have shown increased levels of psychiatric morbidity in young refugees and international adoptees with an origin outside Europe. This study investigated their risk of non-affective psychotic disorders (NAPD) and whether this risk is influenced by early childhood adversity, operationalised as age at adoption/residency, and/or gender. METHODS Register study in Swedish national cohorts born 1972-1990 including 21 615 non-European international adoptees, 42 732 non-European refugees that settled in Sweden at age 0-14 years and 1 610 233 Swedish born. The study population was followed from age 18 to year 2016 for hospitalisations with a discharge diagnosis of NAPD. Hazard ratios (HRs) were calculated in gender stratified Cox regression models, adjusted for household income at age 17. RESULTS The adjusted risks of NAPD were 2.33 [95% confidence interval (CI) 2.07-2.63] for the international adoptees and 1.92 (1.76-2.09) for the former child refugees, relative to the Swedish-born population. For the international adoptees there was a stepwise gradient for NAPD by age of adoption from adjusted HR 1.66 (1.29-2.03) when adopted during the first year of life to adjusted HR 4.56 (3.22-6.46) when adopted at ages 5-14 years, with a similar risk pattern in women and men. Age at residency did not influence the risk of NAPD in the refugees, but their male to female risk ratio was higher than in Swedish-born and the adoptees. CONCLUSION The risk pattern in the international adoptees gives support to a link between early childhood adversity and NAPD. Male gender increased the risk of NAPD more among the refugees.

Associations of neurodevelopmental risk factors with psychosis proneness: Findings from a non-clinical sample of young adults. Compr Psychiatry 2023; 123:152385.

Abstract
Psychotic disorders often develop as the continuum of subclinical symptoms that include hallucination-like and delusion-like experiences, and are commonly referred to as psychotic-like experiences (PLEs). To date, a number of neurodevelopmental risk factors of psychosis have been detected, yet their mutual interplay remains unknown. Therefore, we aimed to investigate the additive association of childhood trauma history, reading disabilities and symptoms of attention-deficit/hyperactivity disorder (ADHD) with psychosis proneness. A total of 3000 young adults (58.3% females, aged 18-35 years) with a negative history of psychiatric treatment were recruited to the cross-sectional study through computer-assisted web interview. Self-reports were administered to measure childhood trauma history, ADHD symptoms and reading disabilities. Linear regression analyses revealed significant main associations of childhood trauma history and reading disabilities with higher levels of PLEs. There were no significant main associations of ADHD with the level of PLEs. However, the associations of all possible interactions between neurodevelopmental risk factors with the level of PLEs were significant. Our findings suggest that childhood trauma history and reading disabilities may additively increase a risk of psychosis. The present findings bring new implications for early intervention strategies in psychosis and posit the rationale of recording the accumulation of neurodevelopmental vulnerabilities in clinical practice.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that occurs in early childhood and can persist to adulthood. It can affect many aspects of a patient's daily life, so it is necessary to explore the mechanism and pathological alterations. For this purpose, we applied induced pluripotent stem cell (iPSC)-derived telencephalon organoids to recapitulate the alterations occurring in the early cerebral cortex of ADHD patients. We found that telencephalon organoids of ADHD showed less growth of layer structures than control-derived organoids. On day 35 of differentiation, the thinner cortex layer structures of ADHD-derived organoids contained more neurons than those of control-derived organoids. Furthermore, ADHD-derived organoids showed a decrease in cell proliferation during development from day 35 to 56. On day 56 of differentiation, there was a significant difference in the proportion of symmetric and asymmetric cell division between the ADHD and control groups. In addition, we observed increased cell apoptosis in ADHD during early development. These results show alterations in the characteristics of neural stem cells and the formation of layer structures, which might indicate key roles in the pathogenesis of ADHD. Our organoids exhibit the cortical developmental alterations observed in neuroimaging studies, providing an experimental foundation for understanding the pathological mechanisms of ADHD.

Parasitic infections as potential risk factors for attention deficit hyperactivity disorder (ADHD) in children. J Parasit Dis 2023; 47:82-92. [PMID: 36910322 PMCID: PMC9998788 DOI: 10.1007/s12639-022-01542-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Accepted: 10/12/2022] [Indexed: 11/27/2022] Open
Abstract
Attention deficit hyperactivity disorder (ADHD) represents a mysterious neuropsychiatric alarming concern due to indefinite etiopathogenesis among children. Notably, the studies which investigated the correlation between ADHD and parasitic infections are insufficient. Therefore, this research aimed to assess the correlation between ADHD and some tissue dwelling and intestinal parasitic infections in children. The study was conducted on 200 children, including 100 children suffering from ADHD (Group I) and 100 healthy children as a control group (Group II). All caregivers fulfilled predesigned sociodemographic form and Conners parent rating scale (CPRS-48) questionnaire. Blood samples were collected to determine hemoglobin level as well as relative eosinophilic count. The presence of anti-Toxoplasma IgG and anti-Toxocara IgG in serum by Enzyme-Linked Immunosorbent Assay (ELISA) was further investigated. Also, micronutrients as zinc, iron, and copper levels were measured. Schistosoma antigen was investigated in urine samples. Stool samples were subjected to direct wet smear, concentration technique and modified Ziehl-Neelsen (MZN) staining for coccidian parasites detection. Cryptosporidium parvum, Giardia lamblia and Entamoeba histolytica antigens were investigated in stool samples. Group I expressed more liability to sociodemographic risk factors, decreased levels of Hb, iron, zinc, and copper with statistically significant difference (P < 0.001). Comparison between Group I and Group II regarding the detected parasitic infections exhibited statistically significant difference except Schistosoma antigen positivity which expressed no statistical significance. The present study concluded that the parasitic infections with their consequences are potential risk factors in children with ADHD indicating that their early diagnosis and treatment may help in ADHD prevention.

Findings from a cross-sectional study in Japan. Front Psychiatry 2023; 14:1133779. [PMID: 37205981 PMCID: PMC10188928 DOI: 10.3389/fpsyt.2023.1133779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 04/04/2023] [Indexed: 05/21/2023] Open
Abstract
Objective Although research has indicated that the prevalence of attention-deficit/hyperactivity disorder (ADHD) may be elevated in individuals with psychotic disorders, as yet, there has been comparatively little research on this association and its effects among adults at the subclinical level. To address this deficit, the current study examined the association between psychotic experiences (PE) and ADHD symptoms in Japanese individuals and whether the presence of ADHD symptoms increases the risk for negative health outcomes in people with PE. Method Data were analyzed from an online sample of 1,452 individuals (age 18-89; 51.5% female) collected in 2021. Information on PE was obtained with the PRIME Screen-Revised (PS-R), while the Adult ADHD Self-Report Scale (ASRS) Screener was used to measure ADHD symptoms. Information was also obtained on a number of health outcomes including anxiety and depressive symptoms and suicidal ideation. Logistic regression was used to assess associations. Results In a fully adjusted analysis PE were associated with almost three times higher odds for ADHD symptoms (OR: 2.92, 95%CI: 1.19-7.17). In an analysis that was restricted to individuals with PE, ADHD symptoms were associated with significantly increased odds for depressive symptoms, lifetime suicidal ideation, perceived stress and severe sleep problems. Conclusion ADHD symptoms are present in some individuals with PE and increase the odds for several detrimental health outcomes in this population. Identifying co-occurring PE and ADHD/ADHD symptoms may facilitate treatment options and help prevent negative health outcomes in individuals with these conditions.

Abstract
Objective The present study aimed to compare the differences in positive screening rates of attention deficit hyperactivity disorder (ADHD) symptoms between parents and teachers in the same sample of primary school students. Concurrently, parental awareness and information sources of ADHD were investigated, and possible relevant factors affecting parental awareness and their influence on positive screening rate of ADHD were analyzed. Methods A cross-sectional study was conducted in Changchun, China, between September 2020 and January 2021. Parents of 1,118 primary school students and 24 head teachers were recruited in the survey. Data were collected through a structured self-administered questionnaire. It consisted of socio-demographic characteristics, ADHD symptom screening questionnaire, parental awareness, and information sources of ADHD. Results Among the 1,118 primary school students, 30 (2.7%) and 60 (5.4%) students were positive for Swanson, Nolan, and Pelham Rating Scale (SNAP-IV) screening in the parent version and teacher version, respectively. Parents had lower positive screening rates for ADHD symptoms than teachers. Relationship with children (mother, OR = 1.552, 95% CI = 1.104-2.180), bachelor degree or above of parents (OR = 1.526, 95% CI = 1.054-2.210), children's sex (girl, OR = 1.442, 95% CI = 1.093-1.904), and age (OR = 1.344, 95% CI = 1.030-1.754), children's grade (grade 2, OR = 0.522, 95% CI = 0.310-0.878; grade 3, OR = 0.388, 95% CI = 0.185-0.782), information sources of ADHD (medical staff, OR = 1.494, 95% CI = 1.108-2.015; family/relative/friend, OR = 1.547, 95% CI = 1.148-2.083; TV/Internet, OR = 3.200, 95% CI = 2.270-4.510) were the factors related to the parental awareness of ADHD. Conclusion Parents and teachers of primary school students recognize ADHD symptoms differently. The positive screening rate of ADHD among teachers was significantly higher than that of parents. Relationship with children, educational level of parents, children's sex, age, and grade, and information sources of ADHD are the relevant factors affecting parental awareness of ADHD. More efforts should be made to disseminate ADHD knowledge through mass media, and medical staff. Fathers, parents with low educational level, and parents of grade 2 and 3 pupils should be encouraged to acquire more knowledge on ADHD to improve the early recognition rate of ADHD symptoms.

Abstract
Current strategies to predict psychosis identify only a small proportion of individuals at risk. Additional strategies are needed to increase capacity for pre-diction and prevention of serious mental illness, ideally during childhood and adolescence. One possible approach would be to investigate systems in which psychosis risk factors are concentrated during childhood. One notable such system is represented by Child and Adolescent Mental Health Services (CAMHS). Although psychotic disorders are uncommon in CAMHS, many risk factors for psychosis are highly prevalent in young people who enter this system. We hypothesized, therefore, that youth attending CAMHS would be a high-risk group for psychosis if followed into adulthood and, furthermore, that CAMHS systems would capture a substantial proportion of future psychosis cases. We constructed a total population cohort study of all Finns born in 1987 (N=55,875), linking together extensive register data on health care contacts from birth through age 28 years. We identified all individuals diagnosed with a psychotic or bipolar disorder by age 28 (N=1,785). The risk of psychosis/bipolar disorder by age 28 years was 1.8% for individuals who had not attended CAMHS during childhood or adolescence, whereas it was 12.8% for those with a history of any outpatient CAMHS contact (odds ratio, OR=7.9, 95% CI: 7.2-8.7). Furthermore, the risk of psychosis/bipolar disorder by age 28 years was 2.3% for individuals without a history of inpatient CAMHS admission, whereas it was 24.0% for those with a history of inpatient CAMHS admission (OR=13.3, 95% CI: 11.9-14.9), and 36.5% for those with a history of inpatient CAMHS admission in adolescence (age 13-17 years) (OR=24.2, 95% CI: 21.2-27.6). Individuals who attended CAMHS but received no mental disorder diagnosis had an equally high risk of subsequently developing a psychosis/bipolar disorder as individuals who did receive a diagnosis (OR=0.9, 99.5% CI: 0.7-1.1). Compared to other CAMHS attendees, individuals who developed psychosis or bipolar disorder were more likely to have had an initial CAMHS diagnosis of depressive or other mood disorder (OR=2.3, 99.5% CI: 1.6-3.0) and disruptive behaviour disorder (OR=1.7, 99.5% CI: 1.2-2.5). Of all psychosis/bipolar diagnoses by age 28 years, 50.2% occurred in individuals who had, at some point in childhood or adolescence, attended CAMHS, indicating that CAMHS represent not only a high-risk but also a high-capacity system for prediction of psychosis/bipolar disorder. These findings suggest an enormous, untapped potential for large-scale psychosis/bipolar disorder prediction and prevention research within existing specialist CAMHS.

Peripheral blood inflammatory markers in patients with attention deficit/hyperactivity disorder (ADHD): A systematic review and meta-analysis. Prog Neuropsychopharmacol Biol Psychiatry 2022; 118:110581.

Abstract
It has been observed that subclinical inflammation might be involved in the pathophysiology of attention deficit/hyperactivity disorder (ADHD). However, studies investigating peripheral blood levels of immune-inflammatory markers have provided mixed findings. We performed a systematic review and meta-analysis of studies comparing unstimulated serum or plasma levels of C-reactive protein (CRP) and cytokines in subjects with ADHD and healthy controls (the PROSPERO registration number: CRD 42021276869). Online searches covered the publication period until 30th Sep 2021 and random-effects meta-analyses were carried out. Out of 1844 publication records identified, 10 studies were included. The levels of interleukin (IL)-6 were significantly higher in studies of participants up to the age of 18 years (k = 10, g = 0.70, 95%CI: 0.10-1.30, p = 0.023) and after including those above the age of 18 years (k = 10, g = 0.71, 95%CI: 0.12-1.31, p = 0.019). In turn, the levels of tumor necrosis factor-α (TNF-α) were significantly lower in subjects with ADHD compared to healthy controls (k = 7, g = -0.16, 95%CI: -0.30 - -0.03, p = 0.020). Individual studies had a high contribution to the overall effect, since the overall effect was no longer significant after removing single studies. No significant differences were found with respect to the levels of CRP, IL-1β, IL-10 and interferon-γ. The present findings indicate that individuals with ADHD tend to show elevated levels of IL-6 and reduced levels of TNF-α. Larger and longitudinal studies recording potential confounding factors and comorbid psychopathology are needed to confirm our findings.

Abstract
SUMMARY
There is a debate in psychiatry regarding whether it is better to use neo-Kraepelinian diagnostic categories or unitary models of psychosis in clinical practice. This article argues that clinicians should use either model as appropriate for the case in question, along with the conceptual framework used in the clinical management of psychosis without a clear biological cause. It first explores the values involved in the development of psychiatric classification systems, the purpose of classification and how we reached the current DSM/ICD and unitary models of psychosis. It then describes a diagnostic approach in which the choice of model should depend on the case in question, and offers a diagnostic protocol to guide the decision.

Abstract
BACKGROUND Validated screening tools are needed to detect subtle cognitive impairment in individuals at-risk for developing psychosis. Here, the utility of the Mini-Mental Status Examination (MMSE) and Penn Computerized Neurocognitive Battery (CNB) were evaluated for detecting cognitive impairment in individuals with psychosis spectrum (PS) symptoms. METHODS Participants (n = 229; 54 % female) completed the MMSE and CNB at baseline and two-year follow-up. PS (n = 91) and typically developing (TD; n = 138) participants were enrolled at baseline based on the presence or absence of PS symptoms. After two years, 65 participants remained PS, 104 participants remained TD, 23 participants had Emergent (EP) subthreshold PS symptoms, and 37 participants were experiencing Other Psychopathology (OP). RESULTS Generally, those with PS had lower scores than TD on both the MMSE (p < 0.0001) and CNB (p < 0.0001). Additionally, OP participants performed lower on the MMSE than TD (p = 0.02). Receiver operating characteristic (ROC) analyses indicated similar area under the curve (AUCs) for the two instruments (0.67); the MMSE showed higher specificity (0.71 vs. 0.62), while the CNB showed higher sensitivity (0.66 vs 0.52). Use of the MMSE and CNB in combination provided the highest diagnostic classification. CONCLUSION The MMSE and CNB can be used to screen for cognitive impairment in PS. The MMSE is better at ruling out PS-related cognitive impairment while the CNB is better at ruling in PS-related cognitive impairment. Overall, our results indicate that both tests are useful in screening for cognitive impairment, particularly in combination, in a PS population.

Abstract
Adderall is one of the most commonly prescribed stimulant medications for attention deficit hyperactivity disorder (ADHD). Although safe and effective when clinically indicated at the appropriate dose, stimulant misuse may lead to serious adverse effects. We report a 29-year-old male with a diagnosis of ADHD who took more than the recommended therapeutic dose of Adderall prescribed by his psychiatrist. He subsequently presented with persistent psychotic symptoms, which responded to oral haloperidol. Due to treatment non-compliance with multiple recurring psychiatric hospitalizations, long-acting injectable haloperidol decanoate was considered to improve compliance and prognosis. The patient’s psychosis remained in remission while on the long-acting injectable. In this case study, we highlight the need for future research to identify stimulant misuse risk factors. Randomized clinical trials are needed to determine the effectiveness of long-acting injectable antipsychotic medication in the management of persistent psychosis secondary to stimulant misuse.

Abstract
PURPOSE/BACKGROUND Stimulants can cause psychotic symptoms at high doses and with parenteral use, but it remains uncertain whether the clinical use of prescription stimulants (PS) at therapeutic doses precipitates psychosis or influences long-term psychosis risk. Although serious, psychosis is a relatively uncommon event that is difficult to detect in brief randomized controlled trials. There have been several large-scale observational studies of PS and psychosis risk, which have not been reviewed; therefore, we conducted a systematic review of observational studies of PS and psychosis risk in adults and children. METHODS/PROCEDURE We conducted a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The protocol was registered with International Prospective Register of Systematic Reviews (CRD42021243484). Eligible studies were longitudinal observational studies, either cohort or case-control, published in English that reported on PS exposure and risk of psychotic events or disorders. Risk of bias assessments were performed with the ROBINS-I instrument. FINDINGS/RESULTS There were 10,736 reports screened, and 8 were ultimately included (n = 232,567 patients): 4 retrospective cohort studies, 1 nested case-control study, 2 self-controlled case series, and 1 prospective cohort study. Exposure to methylphenidate (MPH) was more commonly studied than amphetamine (AMPH). In the 3 studies with lowest risk of bias, there was no effect of MPH exposure on psychosis risk, but there was evidence for increased risk with AMPH in 1 study. IMPLICATIONS/CONCLUSIONS We conclude that observational studies do not support a clear-cut effect of prescribed MPH on psychosis risk but that AMPH has been less well studied and may increase psychosis risk.

Abstract
IMPORTANCE Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are childhood-onset disorders that may persist into adulthood. Several studies have suggested that they may be associated with an increased risk of mortality; however, the results are inconsistent. OBJECTIVE To assess the risk of mortality among persons with ASD or ADHD and their first-degree relatives. DATA SOURCES A search of MEDLINE, Embase, Scopus, Web of Science, and PsycINFO (published from inception to April 1, 2021) was supplemented by searching reference lists of the retrieved articles. STUDY SELECTION Cohort and case-control studies that reported mortality rate ratios (RRs) in persons with ASD or ADHD and/or their first-degree relatives compared with the general population or those without ASD/ADHD were included. DATA EXTRACTION AND SYNTHESIS Screening, data extraction, and quality assessment were performed by at least 2 researchers independently. A random-effects model was used to meta-analyze individual studies and assessed heterogeneity (I2). MAIN OUTCOMES AND MEASURES All-cause mortality in association with ASD or ADHD. Secondary outcome was cause-specific mortality. RESULTS Twenty-seven studies were included, with a total of 642 260 individuals. All-cause mortality was found to be higher for persons with ASD (154 238 participants; 12 studies; RR, 2.37; 95% CI, 1.97-2.85; I2, 89%; moderate confidence) and persons with ADHD (396 488 participants; 8 studies; RR, 2.13; 95% CI, 1.13-4.02; I2, 98%; low confidence) than for the general population. Among persons with ASD, deaths from natural causes (4 studies; RR, 3.80; 95% CI, 2.06-7.01; I2, 96%; low confidence) and deaths from unnatural causes were increased (6 studies; RR, 2.50; 95% CI, 1.49-4.18; I2, 95%; low confidence). Among persons with ADHD, deaths from natural causes were not significantly increased (4 studies; RR, 1.62; 95% CI, 0.89-2.96; I2, 88%; low confidence), but deaths from unnatural causes were higher than expected (10 studies; RR, 2.81; 95% CI, 1.73-4.55; I2, 92%; low confidence). CONCLUSIONS AND RELEVANCE This systematic review and meta-analysis found that ASD and ADHD are associated with a significantly increased risk of mortality. Understanding the mechanisms of these associations may lead to targeted strategies to prevent avoidable deaths in high-risk groups. The substantial heterogeneity between studies should be explored further.

Abstract
Evidence suggests a continuity between obsessive-compulsive disorder (OCD) and schizophrenia. However, the factors that may predict diagnostic progression from OCD to schizophrenia remain unclear. A total of 35,255 adolescents and adults with OCD (ICD-9-CM code: 300.3) were enrolled between 2001 and 2010 and followed up at the end of 2011 for the identification of de novo schizophrenia (ICD-9-CM code: 295). The Kaplan-Meier method was used to estimate incidence rates, and the Cox regression was used to determine the significance of candidate predictors. At the end of the 11-year follow-up period, the crude cumulative progression rate from OCD to schizophrenia was 6%, and the estimated progression rate totaled 7.80%. Male sex (hazard ratio: 1.23), obesity (1.77), autism spectrum disorder (1.69), bipolar disorder (1.69), posttraumatic stress disorder (1.65), cluster A personality disorder (2.50), and a family history of schizophrenia (2.57) also were related to an elevated likelihood of subsequent progression to schizophrenia in patients with OCD. Further study is necessary to elucidate the exact pathomechanisms underlying diagnostic progression to schizophrenia in patients with OCD.

Self-Reported Maternal Parenting Stress From 9 m Is Longitudinally Associated With Child ADHD Symptoms at Age 12: Findings From a Population-Based Birth Cohort Study. Front Psychiatry 2022; 13:806669.

Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) develops in early childhood and carries lifelong impact, but early identification and intervention ensure optimal clinical outcomes. Prolonged or excessive parenting stress may be a response to infant behavioral differences antecedent to developmental disorders such as ADHD, and therefore represents a potentially valuable inclusion in routine early-life assessment. To investigate the feasibility of using routinely-collected self-reported maternal parenting stress as a risk marker for child ADHD, this study investigated the longitudinal association between maternal parenting stress from 1 to 36 months after childbirth and child ADHD in early adolescence. METHODS The sample comprised 2,638 children (1,253 girls) from the Tokyo Teen Cohort population-based birth cohort study. Mothers recorded parenting stress five times from 1 to 36 months following childbirth in the Maternal and Child Health Handbook, a tool used for routine early-life assessment in Japan. Nine years later, mothers evaluated their child's ADHD symptoms at 12 y using the hyperactivity/inattention subscale from the Strength and Difficulties Questionnaire. RESULTS Approximately 7.5% of parents reported that they had parenting stress at 36 m after childbirth. 6.2% of children were evaluated as above the cut-off for ADHD symptoms at 12 y. Parenting stress at 1 and 3-4 m was not associated with child ADHD symptoms at 12 y. However, child ADHD symptoms at 12 y was significantly associated with parenting stress at 9-10 m (unadjusted OR = 1.42, p =.047, 95% CI [1.00, 2/00]), 18 m (unadjusted OR = 1.57, p =.007, 95% CI [1.13, 2.19]) and 36 m (unadjusted OR = 1.67, p =.002, 95% CI [1.20, 2.31]). These associations remained after adjustment for child's sex, age in months and family income. CONCLUSIONS We identified associations between parenting stress at 9-10, 18 and 36 m after childbirth and child ADHD symptoms at 12 years old. Self-reported parenting stress data may have utility as an early indicator for ADHD risk. Participation in early-life health checks, assessment of parenting stress, and tailoring support to family needs should be promoted for early identification and intervention for ADHD.

Abstract
BACKGROUND Childhood attention deficit-hyperactivity disorder (ADHD) is common in psychotic disorders. However, prevalence estimates vary widely and the impact of ADHD on the severity of psychotic symptoms and associated features is unclear. We used the Philadelphia Neurodevelopmental Cohort (PNC; n = 9498 youth age 8-21), which includes a comprehensive structured interview of clinical symptoms and the Penn Computerized Neurocognitive Battery (CNB), to clarify the prevalence of ADHD in psychosis spectrum (PS) youth and determine if comorbid ADHD is associated with severity of psychotic symptoms and cognitive impairment. METHODS Prevalence of ADHD among PS youth was established by comparing PS youth to all other youth in the PNC cohort. Cognition was compared between four groups: typically developing (TD), ADHD, PS without ADHD (PS-ADHD), and PS with ADHD (PS+ADHD). To evaluate the impact of ADHD on psychosis symptomatology, severity of positive and negative psychotic symptoms was compared between PS-ADHD and PS+ADHD groups. RESULTS ADHD was more prevalent in PS youth compared to non-PS youth (45% vs. 20%). Cognition was significantly impaired in PS youth compared to TD youth, but the presence of ADHD in PS youth was not associated with greater cognitive impairment. Co-morbid ADHD was, however, associated with more severe psychosis symptoms in PS youth. CONCLUSION ADHD is more common among PS youth compared to youth without PS symptoms and is associated with more severe psychotic symptoms, but not severity of cognitive impairment. The association between ADHD and psychotic disorders may be mediated by psychosis symptoms in youth and may manifest a more stable cognitive impairment.

Abstract
Exposure to adverse childhood experiences (ACEs) is a risk factor for the development of psychiatric disorders in addition to cardiovascular associated diseases. This risk is elevated when the cumulative burden of ACEs is increased. Laboratory animals can be used to model the changes (as well as the underlying mechanisms) that result in response to adverse events. In this study, using male and female Sprague Dawley rats, we examined the impact of increasing stress burden, utilizing both two adverse early life experiences (parental/offspring high fat diet + limited bedding exposure) and three adverse early life experiences (parental/offspring high fat diet + limited bedding exposure + neonatal inflammation), on maternal care quality and offspring behavior. Additionally, we measured hormones and hippocampal gene expression related to stress. We found that the adverse perinatal environment led to a compensatory increase in maternal care. Moreover, these dams had reduced maternal expression of oxytocin receptor, compared to standard housed dams, in response to acute stress on postnatal day (P)22. In offspring, the two-hit and three-hit models resulted in a hyperlocomotor phenotype and increased body weights. Plasma leptin and hippocampal gene expression of corticotropin releasing hormone (Chrh)1 and Crhr2 were elevated (males) while expression of oxytocin was reduced (females) following acute stress. On some measures (e.g., hyperlocomotion, leptin), the magnitude of change was lower in the three-hit compared to the two-hit model. This suggests that multiple early adverse events can have interactive, and often unpredictable, impacts, highlighting the importance of modeling complex interactions amongst stressors during development.
