Homocysteine levels in first-episode patients with psychiatric disorders

A high homocysteine (Hcy) level is a risk factor for schizophrenia, depression, and bipolar disorder. However, the role of hyperhomocysteinemia as either an independent factor or an auxiliary contributor to specific psychiatric symptoms or disorders remains unclear. This study aimed to examine Hcy levels in first-episode inpatients with psychotic symptoms and various psychiatric diseases to elucidate the association between Hcy levels and psychiatric disorders. This study enrolled 191 patients (aged 18–40 years) with psychiatric disorders. Seventy-five patients were diagnosed with schizophrenia, 48 with acute and transient psychotic disorders, 36 with manic episodes with psychosis, 32 with major depressive episodes with psychosis, and 56 healthy controls. Serum Hcy levels were measured using the enzyme cycle method. A Hcy concentration level of > 15 μmol/L was defined as hyperhomocysteinemia. Hcy levels were significantly higher in first-episode patients with psychiatric disorders compared to healthy controls (5.99 ± 3.60 vs. 19.78 ± 16.61 vs. 15.50 ± 9.08 vs. 20.00 ± 11.33 vs. 16.22 ± 12.06, F = 12.778, P < 0.001). Hcy levels were significantly higher in males with schizophrenia, acute and transient psychotic disorder, and major depressive disorder but not in mania [schizophrenia, (t = -4.727, P < 0.001); acute and transient psychotic disorders, (t = -3.389, P = 0.001); major depressive episode with psychosis, (t = -3.796, P < 0.001); manic episodes with psychosis, (t = -1.684, P = 0.101)]. However, serum Hcy levels were not significantly different among the psychiatric disorder groups (F = 0.139, P = 0.968). Multivariate linear regression showed that males had an increased risk for homocysteinemia. (95% CI = 8.192–15.370, P < 0.001). These results suggest that first-episode patients with psychiatric disorders have higher Hcy levels than in the general population, and men are at greater risk for psychiatric disorders. In conclusion, elevated Hcy levels may contribute to the pathogenesis of first-episode patients with psychotic symptoms.

Integrating human endogenous retroviruses into transcriptome-wide association studies highlights novel risk factors for major psychiatric conditions.

Human endogenous retroviruses (HERVs) are repetitive elements previously implicated in major psychiatric conditions, but their role in aetiology remains unclear. Here, we perform specialised transcriptome-wide association studies that consider HERV expression quantified to precise genomic locations, using RNA sequencing and genetic data from 792 post-mortem brain samples. In Europeans, we identify 1238 HERVs with expression regulated in cis, of which 26 represent expression signals associated with psychiatric disorders, with ten being conditionally independent from neighbouring expression signals. Of these, five are additionally significant in fine-mapping analyses and thus are considered high confidence risk HERVs. These include two HERV expression signatures specific to schizophrenia risk, one shared between schizophrenia and bipolar disorder, and one specific to major depressive disorder. No robust signatures are identified for autism spectrum conditions or attention deficit hyperactivity disorder in Europeans, or for any psychiatric trait in other ancestries, although this is likely a result of relatively limited statistical power. Ultimately, our study highlights extensive HERV expression and regulation in the adult cortex, including in association with psychiatric disorder risk, therefore providing a rationale for exploring neurological HERV expression in complex neuropsychiatric traits.

Genetically predicted fatty liver disease and risk of psychiatric disorders: A mendelian randomization study.

Non-alcoholic fatty liver disease (NAFLD) and alcohol-related liver disease (ArLD) constitute the primary forms of chronic liver disease, and their incidence is progressively increasing with changes in lifestyle habits. Earlier studies have documented a correlation between the occurrence and development of prevalent mental disorders and fatty liver. To investigate the correlation between fatty liver and mental disorders, thus necessitating the implementation of a mendelian randomization (MR) study to elucidate this association. Data on NAFLD and ArLD were retrieved from the genome-wide association studies catalog, while information on mental disorders, including Alzheimer's disease, schizophrenia, anxiety disorder, attention deficit hyperactivity disorder (ADHD), bipolar disorder, major depressive disorder, multiple personality disorder, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and schizophrenia was acquired from the psychiatric genomics consortium. A two-sample MR method was applied to investigate mediators in significant associations. After excluding weak instrumental variables, a causal relationship was identified between fatty liver disease and the occurrence and development of some psychiatric disorders. Specifically, the findings indicated that ArLD was associated with a significantly elevated risk of developing ADHD (OR: 5.81, 95%CI: 5.59-6.03, P < 0.01), bipolar disorder (OR: 5.73, 95%CI: 5.42-6.05, P = 0.03), OCD (OR: 6.42, 95%CI: 5.60-7.36, P < 0.01), and PTSD (OR: 5.66, 95%CI: 5.33-6.01, P < 0.01). Meanwhile, NAFLD significantly increased the risk of developing bipolar disorder (OR: 55.08, 95%CI: 3.59-845.51, P < 0.01), OCD (OR: 61.50, 95%CI: 6.69-565.45, P < 0.01), and PTSD (OR: 52.09, 95%CI: 4.24-639.32, P < 0.01). Associations were found between genetic predisposition to fatty liver disease and an increased risk of a broad range of psychiatric disorders, namely bipolar disorder, OCD, and PTSD, highlighting the significance of preventive measures against psychiatric disorders in patients with fatty liver disease.

Quality of life and sleep, depression, family functioning, and marital adjustment in patients on hemodialysis and peritoneal dialysis.

End-stage renal disease is different from other chronic diseases that the treatment method is as difficult. Our aim in this study was to compare marital adjustment, sexual functions and family functioning between hemodialysis (HD) and peritoneal dialysis (PD) patient. A total of 21 HD and 27 PD patients were included. Beck Depression Inventory (BDI), Short Form-36 (SF-36), Pittsburgh Sleep Quality Index (PSQI), Arizona Sexual Experiences Scale (ASEX), Golombok-Rust Inventory for Sexual Satisfaction (GRISS), Marital Adjustment Test (MAT) and Family Assessment Device (FAD) were applied. BDI scores were significantly higher in HD patients (p < 0.001). According to FAD problem solving (p < 0.001), communication (p = 0.00) and general functioning scores (p = 0.04) were higher in PD. The rate of poor sleep quality was 44.4% in the PD group, and 66.7% in HD group (p = 0.12). General health (p = 0.04), vitality (p < 0.001), mental health (p = 0.00) and social functioning (p = 0.00) scores were lower in HD patients. HD patients are at high risk for psychiatric disorders due to the treatment modality. These patients should be monitored carefully and consultation-liaison services should be increased.

Mendelian randomization analyses reveal causal relationships between brain functional networks and risk of psychiatric disorders.

Dysfunction of brain resting-state functional networks has been widely reported in psychiatric disorders. However, the causal relationships between brain resting-state functional networks and psychiatric disorders remain largely unclear. Here we perform bidirectional two-sample Mendelian randomization (MR) analyses to investigate the causalities between 191 resting-state functional magnetic resonance imaging (rsfMRI) phenotypes (n = 34,691 individuals) and 12 psychiatric disorders (n = 14,307 to 698,672 individuals). Forward MR identified 8 rsfMRI phenotypes causally associated with the risk of psychiatric disorders. For example, the increase in the connectivity of motor, subcortical-cerebellum and limbic network was associated with lower risk of autism spectrum disorder. In adddition, increased connectivity in the default mode and central executive network was associated with lower risk of post-traumatic stress disorder and depression. Reverse MR analysis revealed significant associations between 4 psychiatric disorders and 6 rsfMRI phenotypes. For instance, the risk of attention-deficit/hyperactivity disorder increases the connectivity of the attention, salience, motor and subcortical-cerebellum network. The risk of schizophrenia mainly increases the connectivity of the default mode and central executive network and decreases the connectivity of the attention network. In summary, our findings reveal causal relationships between brain functional networks and psychiatric disorders, providing important interventional and therapeutic targets for psychiatric disorders at the brain functional network level.

Epigenetic mechanisms linking early-life adversities and mental health.

Early-life adversities, whether prenatal or postnatal exposure, have been linked to adverse mental health outcomes later in life increasing the risk of several psychiatric disorders. Research on its neurobiological consequences demonstrated an association between exposure to adversities and persistent alterations in the structure, function, and connectivity of the brain. Consistent evidence supports the idea that regulation of gene expression through epigenetic mechanisms are involved in embedding the impact of early-life experiences in the genome and mediate between social environments and later behavioral phenotypes. In addition, studies from rodent models and humans suggest that these experiences and the acquired risk factors can be transmitted through epigenetic mechanisms to offspring and the following generations potentially contributing to a cycle of disease or disease risk. However, one of the important aspects of epigenetic mechanisms, unlike genetic sequences that are fixed and unchangeable, is that although the epigenetic markings are long-lasting, they are nevertheless potentially reversible. In this review, we summarize our current understanding of the epigenetic mechanisms involved in the mental health consequences derived from early-life exposure to malnutrition, maltreatment and poverty, adversities with huge and pervasive impact on mental health. We also discuss the evidence about transgenerational epigenetic inheritance in mammals and experimental data suggesting that suitable social and pharmacological interventions could reverse adverse epigenetic modifications induced by early-life negative social experiences. In this regard, these studies must be accompanied by efforts to determine the causes that promote these adversities and that result in health inequity in the population.

Neurological or Psychiatric Disorders After Dengue Fever

This cohort study investigates the association between dengue fever and risk of neurological and psychiatric disorders among adults in Taiwan.

Medication and procedural abortions before 13 weeks gestation and risk of psychiatric disorders

BackgroundThe proportion of abortions provided by medication in the US and worldwide has increased greatly since FDA-approval of mifepristone in 2000. While existing research has shown that abortion does not increase risk of mental health problems, no population-based study has examined specifically whether a procedural or medication abortion increases risk of mental health disorders. ObjectiveThis study examined whether mental health disorders increased in the shorter and longer-term after a medication or procedural abortion. Study DesignUsing Danish population registers’ data, we conducted a prospective cohort study in which we included 72,424 females born in Denmark between 1980-2006, who were ages 12-38 during the study period and had a first first-trimester abortion before 13 weeks gestation in 2000-2018. Females with no previous psychiatric diagnoses were followed from one year before their abortion until their first psychiatric diagnosis, December 31, 2018, emigration from Demark, or death, whichever came first. Risk of any first psychiatric disorder was defined as a recorded psychiatric diagnosis at an in- or out-patient facility from the one year after to more than 5 years after a medication or procedural abortion relative to the year beforehand. Results were adjusted for calendar year, age, gestational age, partner status, prior mental and physical health, childbirth history, childhood environment, and parental mental health history. ResultsFemales having medication (n = 37,155) and procedural abortions (n = 35,269) had the same risk of any first psychiatric diagnosis in the year after their abortion relative to the year before their abortion (medication abortion adjusted incidence rate ratio [MaIRR] = 1.02, 95% CI: 0.93-1.12; procedural abortion adjusted incidence rate ratio [PaIRR] = 0.94, 95% CI: 0.86-1.02). Moreover, as more time from the abortion passed, the risk of a psychiatric diagnoses decreased relative to the year before their abortion for each abortion method (MaIRR 1-2 years after = 0.89, 95% CI: 0.80-0.98; PaIRR 1-2 years after = 0.81, 95% CI: 0.88-1.05; MaIRR 2-5 years after = 0.77, 95% CI: 0.71-0.84; PaIRR 2-5 years after = 0.72, 95% CI: 0.67-0.78; MaIRR 5+ years after = 0.58, 95% CI: 0.53-0.63; PaIRR 5+ years after = 0.54, 95% CI: 0.50-=0.58). ConclusionsBecause the risk of psychiatric diagnoses was the same in the year after relative to the year before a medication and procedural abortion and the risk did not increase as more time after the abortion increased, neither abortion method increased risk of mental health disorders in the shorter or longer-term.

Study on Predictor Variables for Different Dimensions of Mental Health among Melavoi Village of Covid-19 Affected Young Adults Living in Anantapuram District, Andhra Pradesh

Early adulthood is an extremely diverse period of life. it encompasses a wide range of lifestyle choices and responsibilities. The pandemic has impacted the mental health of young adults very severely. Covid-19 pandemic there has been an increased risk of psychiatric disorders, chronic trauma with an eventual risk of increased suicidality and suicidal behavior linking this to immune mediated mechanisms of stress. For better dealing with these psychosocial issues of different strata of the society, psychosocial crisis prevention and intervention models should be urgently developed by the government, health care personnel and other stakeholders. Apt application of internet services, technology and social media to curb both pandemic and infodemic needs to be instigated. The main focus of the study was to swot on “Study on predictor variables for different dimensions of mental health among Melavoi village of Covid-19 affected young adults living in Anantapuram district, Andhra Pradesh”. Purposive random sampling technique was selected for the study. The respondents were selected from Melavoi village of Anantapuram district, Andhra Pradesh. Male and Female who are in the age group of 18-35 years affected with Covid-19 was selected for the study. The group consists of 30 Covid-19 affected young adults of 15 males and 15 females from Melavoivillage for the study. The study found that Covid-19 outbreak made respondents to experience lot of mental health problems like emotional distress, anxiety, stress, despair, dissatisfaction, impatience irrespective of gender.

First-episode psychiatric disorder risk from SARS-CoV-2 infection, a clinical analysis with Chinese psychiatric inpatients.

The extensive spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) throughout China in late 2022 has underscored the correlation between this virus and severe psychiatric disorders. Nevertheless, there remains a dearth of reported corresponding clinical and pathological features. Accordingly, we retrospectively reviewed the electronic medical records of psychiatric inpatients for seven days from early January 2023. Twenty-one inpatients who developed first-episode psychiatric disorders within two weeks after SARS-CoV-2 infection were recruited, while 24 uninfected the first-episode psychiatric inpatients were selected as controls. Comparative analyses of clinical manifestations, routine laboratory, and imaging examinations were performed. Our investigation revealed a 330% increase in first-episode psychiatric inpatients incidence after SARS-CoV-2 infection in 2023 compared to the preceding year without infections. Most cases exhibited psychiatric symptoms within a week of infection, resolving about two weeks with no residual symptoms after a three month. One-way ANOVA analysis between inpatients characterized by psychotic symptoms and hyperthermia was significant. Infected inpatients displayed elevated cytokine levels of interleukin-4, interleukin-8, and interferon-α, and decreased levels of eosinophils and basophils. These finding suggested that SARS-CoV-2 may contribute to the development of psychiatric disorders, likely mediated by the virus-induced inflammatory response and neuronal dysfunction in the context of psychological distress.

Is waiting for rewards good for you? No association between impulsive choice, psychopathology, and functional outcomes in a large cohort sample

AbstractBackgroundA stronger preference for immediate rewards has been reported in individuals with ADHD and other disorders. However, the consistency of the associations between this preference and psychiatric conditions as well as functional outcomes have been questioned. Research on its association with longitudinal outcomes is scarce.MethodsThe current study used data on a choice delay task (CDT) from a school‐based cohort of Brazilian children with those at higher risk for psychiatric disorders over‐sampled (n = 1917). The sample included typically developing children (n = 1379), those with ADHD (n = 213), and other disorders. The frequency of the trials where children chose a larger later reward versus a smaller sooner reward was compared for those with ADHD and typically developing children. Cross‐sectionally and longitudinally, the study also evaluated whether children's preference for larger delayed rewards at baseline predicted the presence of psychiatric disorders and functional life outcomes (academic performance, alcohol use, early pregnancy, criminal conviction, BMI).ResultsChildren with ADHD and their typically developing peers performed similarly on the CDT. Their baseline task performance was not related to psychiatric conditions or life outcomes.ConclusionsThe current results raise questions regarding the use of the CDT with diverse populations and whether a preference for larger delayed rewards is predictive of positive long‐term outcomes as widely assumed.

Cardiomyopathies and Psychiatric Disorders: An Overview and General Clinical Recommendations.

The association between cardiomyopathies (CMPs) and psychiatric disorders is a complex and bidirectional phenomenon that involves multiple mechanisms and factors. CMPs may raise the risk of psychiatric disorders due to the psychological stress, physical limitations, social isolation, or poor prognosis associated with the underlying disease. Psychiatric disorders, on the other hand, can increase the possibility of developing or worsening CMPs due to the behavioral, neuroendocrine, inflammatory, or pharmacological effects of mental illness or its treatment. Moreover, some common genetic or environmental factors may have a relevant influence on both conditions. With this comprehensive review, we sought to provide an overview of the current evidence on the strict and intriguing interconnection between CMPs and psychiatric disorders, focusing on the epidemiology, pathophysiology, clinical implications, and management strategies.

Increased risk of psychiatric disorder in patients with hearing loss: a nationwide population-based cohort study

BackgroundHearing loss has been shown to be a risk factor for psychiatric disorders. In addition, long-term hearing loss is associated with increased hospitalization and mortality rates; however, the increased risk and duration of effect of hearing loss in combination with other chronic diseases on each psychiatric disorder are still not clearly defined. The purpose of this article is to clarify the risk of hearing loss for each disorder over time.MethodsThis was a retrospective cohort study, and a national health insurance research database in Taiwan was utilized. All (n = 1,949,101) Taiwanese residents who had a medical visit between 2000 and 2015 were included. Patients with hearing loss and a comparative retrospective cohort were analyzed. Every subject was tracked individually from their index date to identify the subjects who later received a diagnosis of a psychiatric disorder. The Kaplan‒Meier method was used to analyze the cumulative incidence of psychiatric disorders. Cox regression analysis was performed to identify the risk of psychiatric disorders.ResultsA total of 13,341 (15.42%) and 31,250 (9.03%) patients with and without hearing loss, respectively, were diagnosed with psychiatric disorders (P < 0.001). Multivariate analysis indicated that hearing loss significantly elevated the risk of psychiatric disorders (adjusted HR = 2.587, 95% CI 1.723–3.346, p < 0.001).ConclusionOur findings indicate that patients with hearing loss are more likely to develop psychiatric disorders. Furthermore, the various psychiatric disorders are more likely to occur at different times. Our findings have important clinical implications, including a need for clinicians to implement early intervention for hearing loss and to pay close attention to patients’ psychological status.Trial registration TSGHIRB No. E202216036.

A comprehensive assessment of toxoplasmosis and its dormant impact on psychotic disorders (Review).

Toxoplasmosis is a pathological condition induced by the parasite, Toxoplasma gondii (T. gondii), which has a notable affinity for the cellular components of the central nervous system. Over the decades, the relationship between toxoplasmosis and the development of psychiatric disorders has generated profound interest within the scientific community. Whether considering immunocompetent or immunocompromised patients, epidemiological studies suggest that exposure to T. gondii may be associated with a higher risk of certain psychiatric disorders. However, there are extensive debates regarding the exact nature of this association and how T. gondii is involved in the pathogenesis of these disorders. Toxoplasmosis has long been considered an asymptomatic infection among immunocompetent patients. However, there appears to be an association between chronic brain infection with T. gondii and alterations in patient neuronal architecture, neurochemistry and behavior. The present review aimed to compile statements and pathophysiological hypotheses regarding the potential association between toxoplasmosis and psychotic disorders. Further research is necessary for understanding the potential relationship of T. gondii infection and psychotic disorders.

Genetic predisposition for negative affect predicts mental health burden during the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic was accompanied by an increase in mental health challenges including depression, stress, loneliness, and anxiety. Common genetic variants can contribute to the risk for psychiatric disorders and may present a risk factor in times of crises. However, it is unclear to what extent polygenic risk played a role in the mental health response to the COVID-19 pandemic. In this study, we investigate whether polygenic scores (PGSs) for mental health-related traits can distinguish between four resilience-vulnerability trajectories identified during the COVID-19 pandemic and associated lockdowns in 2020/21. We used multinomial regression in a genotyped subsample (n = 1316) of the CovSocial project. The most resilient trajectory characterized by the lowest mental health burden and the highest recovery rates served as the reference group. Compared to this most resilient trajectory, a higher value on the PGS for the well-being spectrum decreased the odds for individuals to be in one of the more vulnerable trajectories (adjusted R-square = 0.3%). Conversely, a higher value on the PGS for neuroticism increased the odds for individuals to be in one of the more vulnerable trajectories (adjusted R-square = 0.2%). Latent change in mental health burden extracted from the resilience-vulnerability trajectories was not associated with any PGS. Although our findings support an influence of PGS on mental health during COVID-19, the small added explained variance suggests limited utility of such genetic markers for the identification of vulnerable individuals in the general population.

Susceptibility to Treatment-Resistant Depression Within Families

Antidepressant responses and the phenotype of treatment-resistant depression (TRD) are believed to have a genetic basis. Genetic susceptibility between the TRD phenotype and other psychiatric disorders has also been established in previous genetic studies, but population-based cohort studies have not yet provided evidence to support these outcomes. To estimate the TRD susceptibility and the susceptibility between TRD and other psychiatric disorders within families in a nationwide insurance cohort with extremely high coverage and comprehensive health care data. This cohort study assessed data from the Taiwan national health insurance database across entire population (N = 26 554 001) between January 2003 and December 2017. Data analysis was performed from August 2021 to April 2023. TRD was defined as having experienced at least 3 distinct antidepressant treatments in the current episode, each with adequate dose and duration, based on the prescribing records. Then, we identified the first-degree relatives of individuals with TRD (n = 34 467). A 1:4 comparison group (n = 137 868) of first-degree relatives of individuals without TRD was arranged for the comparison group, matched by birth year, sex, and kinship. Modified Poisson regression analyses were performed and adjusted relative risks (aRRs) and 95% CIs were calculated for the risk of TRD, the risk of other major psychiatric disorders, and different causes of mortality. This study included 172 335 participants (88 330 male and 84 005 female; mean [SD] age at beginning of follow-up, 22.9 [18.1] years). First-degree relatives of individuals with TRD had lower incomes, more physical comorbidities, higher suicide mortality, and increased risk of developing TRD (aRR, 9.16; 95% CI, 7.21-11.63) and higher risk of other psychiatric disorders than matched control individuals, including schizophrenia (aRR, 2.36; 95% CI, 2.10-2.65), bipolar disorder (aRR, 3.74; 95% CI, 3.39-4.13), major depressive disorder (aRR, 3.65; 95% CI, 3.44-3.87), attention-deficit/hyperactivity disorders (aRR, 2.38; 95% CI, 2.20-2.58), autism spectrum disorder (aRR, 2.26; 95% CI, 1.86-2.74), anxiety disorder (aRR, 2.71; 95% CI, 2.59-2.84), and obsessive-compulsive disorder (aRR, 3.14; 95% CI, 2.70-3.66). Sensitivity and subgroup analyses validated the robustness of the findings. To our knowledge, this study is the largest and perhaps first nationwide cohort study to demonstrate TRD phenotype transmission across families and coaggregation with other major psychiatric disorders. Patients with a family history of TRD had an increased risk of suicide mortality and tendency toward antidepressant resistance; therefore, more intensive treatments for depressive symptoms might be considered earlier, rather than antidepressant monotherapy.

Distinct Longitudinal Brain White Matter Microstructure Changes and Associated Polygenic Risk of Common Psychiatric Disorders and Alzheimer’s Disease in the UK Biobank

BackgroundDuring the course of adulthood and aging, white matter (WM) structure and organization are characterized by slow degradation processes such as demyelination and shrinkage. An acceleration of such aging processes has been linked to the development of a range of diseases. Thus, an accurate description of healthy brain maturation, particularly in terms of WM features, is fundamental to the understanding of aging. MethodsWe used longitudinal diffusion magnetic resonance imaging to provide an overview of WM changes at different spatial and temporal scales in the UK Biobank (UKB) (n = 2678; agescan 1 = 62.38 ± 7.23 years; agescan 2 = 64.81 ± 7.1 years). To examine the genetic overlap between WM structure and common clinical conditions, we tested the associations between WM structure and polygenic risk scores for the most common neurodegenerative disorder, Alzheimer’s disease, and common psychiatric disorders (unipolar and bipolar depression, anxiety, obsessive-compulsive disorder, autism, schizophrenia, attention-deficit/hyperactivity disorder) in longitudinal (n = 2329) and cross-sectional (n = 31,056) UKB validation data. ResultsOur findings indicate spatially distributed WM changes across the brain, as well as distributed associations of polygenic risk scores with WM. Importantly, brain longitudinal changes reflected genetic risk for disorder development better than the utilized cross-sectional measures, with regional differences giving more specific insights into gene-brain change associations than global averages.Conclusions: We extend recent findings by providing a detailed overview of WM microstructure degeneration on different spatial levels, helping to understand fundamental brain aging processes. Further longitudinal research is warranted to examine aging-related gene-brain associations.

Behavioral and Psychiatric Disorders in Syndromic Autism.

Syndromic autism refers to autism spectrum disorder diagnosed in the context of a known genetic syndrome. The specific manifestations of any one of these syndromic autisms are related to a clinically defined genetic syndrome that can be traced to certain genes and variants, genetic deletions, or duplications at the chromosome level. The genetic mutations or defects in single genes associated with these genetic disorders result in a significant elevation of risk for developing autism relative to the general population and are related to recurrence with inheritance patterns. Additionally, these syndromes are associated with typical behavioral characteristics or phenotypes as well as an increased risk for specific behavioral or psychiatric disorders and clinical findings. Knowledge of these associations helps guide clinicians in identifying potentially treatable conditions that can help to improve the lives of affected patients and their families.

Assessment of mental health and quality of life among children with congenital heart disease.

The current study aimed to determine the prevalence of specific psychiatric disorders, identify predictors associated with these disorders, and assess the quality of life (QoL) among children with congenital heart disease. This comparative cross-sectional study was conducted in the National Heart Institute outpatient clinics. It included 204 children with structural congenital heart defects (CHD). In addition to assessing QoL with the Pediatric Quality of Life Inventory scale, the Mini-International Neuropsychiatric Interview for Children and Adolescents was utilized to identify psychiatric disorders in the children studied. Children with CHD were at increased risk for mood and anxiety disorders. They were also more susceptible to obsessive-compulsive disorder than the comprative healthy group. In children with CHD, the cyanotic group demonstrated a greater decrease in QoL than the acyanotic group. Children with CHD have an increased risk of psychiatric disorders and a lower overall QoL score.
