Influence of the typology and timing of childhood trauma in psychoticism.

PURPOSE: Child maltreatment (CM) is associated with psychosis; however little is known about the frequency, type, and timing of abuse in the personality pathology domain of psychoticism (PSY) in the DSM-5. The purpose of this study was to analyze childhood trauma typology and frequency according to gender and to identify sensitive periods of susceptibility to CM in women with high PSY. METHODS: The Maltreatment and Abuse Chronology Exposure (MACE) scale was used to evaluate the frequency, severity and timing of each type of maltreatment. The full sample consisted of 83 participants with different psychiatric diagnoses. Psychoticism was assessed with the DSM-5 Personality Inventory (PID-5). To identify the differences in CM exposure between the PSY+ (high psychoticism) and PSY- (low psychoticism) groups, the Mann-Whitney U test, the chi square test and random forest (RF) test were used. RESULTS: Comparing PSY + and PSY-, revealed gender differences in the impact of abuse, with highly frequent and severe types of abuse, in women. In women, PSY + and PSY-, were differentiated especially in non-verbal emotional abuse, peer physical bullying and parental verbal abuse. Several periods with a major peak at age seven followed by peaks at age 17 and 12 years old were identified. CONCLUSION: Increased exposure to CM occurs in women with PSY+. A sensitivity to CM exposure during early childhood and late adolescence could be a risk factor for psychoticism in women.

The role of personality dimensions, depressive symptoms and other psychosocial variables in predicting postpartum suicidal ideation: a cohort study.

Suicidability has been associated with neuroticism and psychoticism, but its role during perinatal period has not been analyzed. We explore the association between personality dimensions, depressive symptoms, and other psychosocial variables in postpartum suicidal ideation. A cohort of 1795 healthy Spanish women from the general population was assessed for suicidal ideation (EPDS-Item10) in early postpartum, 8 and 32 weeks postpartum. Sociodemographic, obstetric, and reproductive variables, psychiatric history, social support, stressful life-events during pregnancy, depressive symptoms (EPDS), and the Eysenck's personality dimensions (EPQ-RS) were also assessed at baseline. A major depressive episode (DSM-IV) was confirmed in women with EPDS>10 at follow-up assessments. Descriptive, bivariate, and multivariate analyses were conducted. Adjusted logistic regression analysis was reported as odds ratio (ORs) with 95% confidence intervals (CIs). Seven percent of mothers reported suicidal ideation during the first 8 months postpartum. Sixty-two percent of women with suicidal ideation had a major depressive episode at 8 weeks, and 70% at 32 weeks postpartum. Neuroticism and psychoticism predicted suicidal ideation throughout the first 2 weeks after delivery (OR, 1.03; 95%CI 1.01-1.06; and OR, 1.03; 95%CI 1.01-1.05 respectively). Early postpartum depressive symptoms (OR 1.2; 95%CI 1.11-1.26), personal psychiatric history (OR 2.1; 95%CI 1.33-3.27), and stressful life events during pregnancy (OR 1.88; 95%CI 1.12-3.16) also emerged as predictors of postpartum suicidal ideation. Analysis of women for postpartum suicidal ideation should include not only psychiatric symptoms but also psychosocial assessment (i.e., covering psychiatric history, stressful events, or long-standing personality vulnerabilities) in order to identify those in need of early psychosocial or psychiatric care.

Risk factors and topographies for self-injurious behaviour in a sample of adults with intellectual developmental disorders.

BACKGROUND: Self-injurious behaviour (SIB) is a prevalent form of challenging behaviour in people with intellectual developmental disorders (IDD). Existing research has yielded conflicting findings concerning the major risk factors involved, and in addition, SIB shows multiple topographies and presentations. Although presence of autism spectrum disorders (ASD) and severity of intellectual disability (ID) are known risk factors for SIB, there are no studies comparing SIB topographies by severity degrees of ID and ASD. The purpose of the present paper has been to identify risk factors and topographies for SIB in a representative, stratified and randomised sample of adults with IDD. METHOD: This study was conducted on the basis of data collected by the POMONA-ESP project, in a sample of 833 adults with IDD. Data concerning demographic and health information, ASD symptoms, psychopathology and ID, have been analysed to determine the presence of risk factors for SIB among participants and to explore the occurrence and topographies of SIB across different severity levels of ID and ASD symptoms. RESULTS: Self-injurious behaviour prevalence in the sample was 16.2%. Younger age, oral pain, greater severity of ID, presence of dual diagnosis, psychiatric medication intake and higher scores on Childhood Autism Rating Scale were risk factors for SIB among participants, whereas number of areas with functioning limitations, place of residence, diagnosis of epilepsy and sex were not. SIB was more frequent in participants with ASD symptoms regardless of its severity level, and they displayed a higher number of different topographies of SIB. People with profound ID without co-morbid ASD symptoms showed similar results concerning SIB prevalence and topographies. CONCLUSIONS: Knowledge on risk factors and topographies of SIB might play a vital role in the development of prevention strategies and management of SIB in people with IDD. The mere presence of ASD symptoms, regardless of its severity level, can be a crucial factor to be taken into account in assessing SIB. Accordingly, the presence of SIB in people with ID, especially when presented with a varied number of topographies, might provide guidance on ASD differential diagnosis.

Higher psychoticism as a predictor of thoughts of harming one's infant in postpartum women: a prospective study.

BACKGROUND: Some women experience thoughts of harming their infants during the early postpartum period. These intrusive thoughts are conceptually similar to obsessive-compulsive disorder. The aim of our study was to assess whether personality characteristics may predict a mother's development of postpartum thoughts of harming her infant. METHODS: We studied 137 women with no psychiatric history. They were assessed at two different times during the postpartum period (2-3days after giving birth and during the 8th week following delivery). We assessed postpartum thoughts of harming one's infant with a semi-structured interview conducted in person. Personality characteristics were assessed with the Eysenck Personality Questionnaire. Depression was assessed with the Edinburgh Postnatal Depression Scale and with a structured interview (Diagnostic Interview for Genetic Studies). We also assessed socio-demographic variables, obstetric variables and stressful life events. Adjusting for age, depression and stressful life events, logistic regression was conducted to explore the relationship between a woman's personality characteristics and postpartum thoughts of harming her infant. RESULTS: Women with postpartum thoughts of harming their infants scored higher in EPQ-Psychoticism (P=0.003) but not in neuroticism or extraversion. EPQ-Psychoticism was significantly associated with the presence of postpartum intrusive thoughts (OR=1.67, p=0.003) after adjusting for other personality dimensions, age, depression and life stress. Those women scoring 5 or higher in EPQ-Psychoticism were 5.5 times more likely to report postpartum intrusive thoughts (p=0.004). CONCLUSIONS: In healthy women without psychiatric history, psychoticism is a predictor of postpartum thoughts of harming their infants.

Cholesterol dysregulation in peripheral blood mononuclear cells of Alzheimer's disease.

Cholesterol and the immune system are involved in Alzheimer's Disease (AD). To investigate the relations among them, we compared the cholesterol content in peripheral blood mononuclear cells (PBMC) of cognitively healthy controls and patients with mild cognitive impairment (MCI) and AD in two independent samples. Free cholesterol content of PBMC was lower in MCI and AD patients, and was modulated by APOE genotype. A decrease of CD8+ and an increase of CD16+ was also found in AD patients. These results suggest that cholesterol levels in PBMCs may represent an early signature of the disease and support the involvement of immune system in AD.

Association of common copy number variants at the glutathione S-transferase genes and rare novel genomic changes with schizophrenia.

Copy number variants (CNVs) are a substantial source of human genetic diversity, influencing the variable susceptibility to multifactorial disorders. Schizophrenia is a complex illness thought to be caused by a number of genetic and environmental effects, few of which have been clearly defined. Recent reports have found several low prevalent CNVs associated with the disease. We have used a multiplex ligation-dependent probe amplification-based (MLPA) method to target 140 previously reported and putatively relevant gene-containing CNV regions in 654 schizophrenic patients and 604 controls for association studies. Most genotyped CNVs (95%) showed very low (<1%) population frequency. A few novel rare variants were only present in patients suggesting a possible pathogenic involvement, including 1.39 Mb overlapping duplications at 22q11.23 found in two unrelated patients, and duplications of the somatostatin receptor 5 gene (SSTR5) at 16p13.3 in three unrelated patients. Furthermore, among the few relatively common CNVs observed in patients and controls, the combined analysis of gene copy number genotypes at two glutathione S-transferase (GST) genes, GSTM1 (glutathione S-transferase mu 1) (1p13.3) and GSTT2 (glutathione S-transferase theta 2) (22q11.23), showed a statistically significant association of non-null genotypes at both loci with an additive effect for increased vulnerability to schizophrenia (odds ratio of 1.92; P=0.0008). Our data provide complementary evidences for low prevalent, but highly penetrant chromosomal variants associated with schizophrenia, as well as for common CNVs that may act as susceptibility factors by disturbing glutathione metabolism.

Psychopathology and personality traits in psychotic patients and their first-degree relatives.

Personality dimensions have been associated with symptoms dimensions in schizophrenic patients (SP). In this paper we study the relationships between symptoms of functional psychoses and personality dimensions in SP and their first-degree relatives (SR), in other psychotic patients (PP) and their first-degree relatives (PR), and in healthy controls in order to evaluate the possible clinical dimensionality of these disorders. Twenty-nine SP, 29 SR, 18 PP, 18 PR and 188 controls were assessed using the temperament and character inventory (TCI-R). Current symptoms were evaluated with positive and negative syndrome scale (PANSS) using the five-factor model described previously (positive [PF], negative [NF], disorganized [DF], excitement [EF] and anxiety/depression [ADF]). Our TCI-R results showed that patients had different personality dimensions from the control group, but in relatives, these scores were not different from controls. With regard to symptomatology, we highlight the relations observed between harm avoidance (HA) and PANSS NF, and between self-transcendence (ST) and PANSS PF. From a personality traits-genetic factors point of view, schizophrenia and other psychosis may be initially differentiated by temperamental traits such as HA. The so-called characterial traits like ST would be associated with the appearance of psychotic symptoms.

Long lasting behavioural effects on cuprizone fed mice after neurotoxicant withdrawal.

Destruction of the myelin sheath in the central nervous system (CNS) is prominent in many clinico-pathologic conditions. Among animal models that reproduce the pathological features of de- and remyelination processes, the mouse model of cuprizone administration is widely used. Both hyperactivity and motor impairment have been reported upon cuprizone exposure. The aim of the present study was to assess behaviour in mice after CPZ withdrawal.To summarize, animals showed hypo-activity and deficits in motor coordination when they were subjected to acute demyelinating insult while minor exploratory activity, impairment in motor coordination and lower anxiety levels emerged when remyelination was reached following cuprizone withdrawal. A recovery period of 6 weeks after removal of CPZ was not accompanied by a similar return of normal activity indicating long lasting behavioural effects caused by this neurotoxicant. Specifically, the recovery group showed impairments in neurological functions involved in sensorimotor, neuromuscular, motor coordination and the capacity to cope with a stress-inducing event.

Mood changes after delivery: role of the serotonin transporter gene.

BACKGROUND: Polymorphic variations in the serotonin transporter gene (5-HTT) moderate the depressogenic effects of tryptophan depletion. After childbirth there is a sharp reduction in brain tryptophan availability, thus polymorphic variations in 5-HTT may play a similar role in the post-partum period. AIMS: To study the role of 5-HTT polymorphic variations in mood changes after delivery. METHOD: One thousand, eight hundred and four depression-free Spanish women were studied post-partum. We evaluated depressive symptoms at 2-3 days, 8 weeks and 32 weeks post-partum. We used diagnostic interview to confirm major depression for all probable cases. Based on two polymorphisms of 5-HTT (5-HTTLPR and STin2 VNTR), three genotype combinations were created to reflect different levels of 5-HTT expression. RESULTS: One hundred and seventy-three women (12.7%) experienced major depression during the 32-week post-partum period. Depressive symptoms were associated with the high-expression 5-HTT genotypes in a dose-response fashion at 8 weeks post-partum, but not at 32 weeks. CONCLUSIONS: High-expression 5-HTT genotypes may render women more vulnerable to depressive symptoms after childbirth.

The relationship between the level of exposure to stress factors and cannabis in recent onset psychosis.

BACKGROUND: There is a lack of studies investigating the dose-response effect of childhood trauma, recent events and cannabis use on recent psychosis. This study aims to determine the relationship between the level of exposure to stress factors and cannabis use with psychosis and to determine the combination effect among these factors in predicting a psychotic disorder. METHODS: 146 recent onset psychotic (ROP) patients and 61 healthy controls were included. Childhood trauma was evaluated using the childhood trauma questionnaire (CTQ) and recent events using the Holmes-Rahe social readjustment scale. The pattern of cannabis use was assessed by a detailed interview. A hierarchical multiple regression was run in order to determine both the cumulative and independent contribution of each factor in predicting a psychotic disorder. RESULTS: The highest levels of exposure to childhood trauma and cannabis were associated with psychosis while neither low nor high recent event exposure was associated. The combined effect of risk factors yielded a significant association with psychosis (×2 = 86.76, p < .001) explaining the 49% of its variation. ROP were more likely to be exposed to one, two or three environmental factors than HC. Exposed to two or all factors were 7.5-fold and 26.7-fold more likely to have a diagnosis of psychosis, respectively. CONCLUSIONS: Our study provides evidence for a cumulative and a dose-response effect of environmental factors on recent psychosis. Considering that cannabis use and stress are highly prevalent in the population with psychosis, investigations of their relationships are needed to implement targeted prevention and treatment strategies.

Sustained and selective attention deficits as vulnerability markers to psychosis.

The first descriptions of schizophrenia emphasized attention problems patients with schizophrenia have but recent results evidence that other psychotic disorders share them. We compared the performance in sustained and selective attention between psychotic patients (P), their healthy first degree relatives (R) and healthy volunteers (C) to prove whether these alterations could be an endophenotype of vulnerability to psychosis. We also compared the performance of schizophrenic patients (SZP) and that of patients with other functional psychoses (OP) in order to prove whether these alterations are specific of any psychotic disorder. Seventy-six P, 70 R and 39 C were included in the study. A selective attention index, comprising TMT A and B and Stroop Test, and a sustained attention index comprising the Continuous Performance Test were calculated. We conducted an univariant general linear model to compare three group performances in these indexes, with age, sex and years of education as a covariables. We found significant differences between the indexes when we compared P, R and C. No differences in performance were found between SZP and OP. Our data showed that sustained and selective attention alterations could be a vulnerability factor to psychotic disorders in general, but they were not specific of schizophrenia.

Schizotypal traits and cognitive performance in siblings of patients with psychosis.

INTRODUCTION: Schizotypy has been proposed to be the expression of genetic vulnerability to schizophrenia. The available literature shows cognitive similarities between schizotypy and schizophrenia, with mildly impaired performance being associated with schizotypy. This study aims to determine the relationship between schizotypy and cognitive performance in siblings of patients with psychosis. METHODS: Schizotypal features and cognitive performance on a neuropsychological battery were compared between 48 siblings of patients with psychosis and 44 healthy controls. The relationships between schizotypy and cognitive performance were analysed by controlling the condition of being a sibling. RESULTS: Siblings showed poorer performance on vigilance/sustained attention (M = 37.6; SD = 7.1) and selective attention/interference control/working memory (M = 23.28; SD = 2.7) tasks. The variance in vigilance/sustained attention performance was explained, at 30%, by the interpersonal factor of schizotypy on the suspiciousness dimension and the condition of being a sibling. CONCLUSIONS: Interpersonal features of schizotypy in siblings of patients with psychosis are associated with deficits in vigilance/sustained attention performance.

Expression of discoidin domain receptor 1 during mouse brain development follows the progress of myelination.

Discoidin domain receptor 1 is a tyrosine kinase receptor expressed in a variety of tissues including the brain. This study describes mRNA and protein expression of discoidin domain receptor 1 in mouse brain during development and provides new insights into its role during gliogenesis and neurogenesis. We performed in situ hybridization for discoidin domain receptor 1 in mouse brains at embryonic day 18, postnatal days 5, 9, 15, 21 and adulthood and observed a diffuse pattern in the proliferative areas during embryogenesis. From postnatal day 5 onwards, a defined cellular expression pattern of discoidin domain receptor 1 was observed, mainly located in white matter tracts and following a spatio-temporal pattern that overlapped the progress of myelination. Next, we performed double-labeling reactions (in situ hybridization followed by immunohistochemistry) that confirmed that discoidin domain receptor 1 was expressed by mature oligodendrocytes. We observed that cells positive for discoidin domain receptor 1 also expressed carnosine and anti-adenomatous polyposis coli, two mature oligodendrocyte markers. Based on the localization of discoidin domain receptor 1 specifically in the white matter fiber tracts during postnatal development, we suggest that discoidin domain receptor 1 participates in the development and maintenance of the myelin sheath.

Free thyroxine levels are associated with cognitive changes in individuals with a first episode of psychosis: A prospective 1-year follow-up study.

The results of previous cross-sectional studies suggest that free thyroxine (FT4) levels are associated with cognitive abilities (particularly attention/vigilance) during the early stages of psychosis. We aimed to explore whether hypothalamic-pituitary-thyroid hormones predict cognitive changes in a 1-year longitudinal study following first episodes of psychosis (FEP). We studied 36 FEP patients and a control group of 50 healthy subjects (HS). Plasma levels of thyroid-stimulating hormone (TSH) and FT4 were measured. Cognitive assessment was performed with the MATRICS Cognitive Consensus Cognitive Battery (MCCB). FEP patients were assessed twice (baseline and after 1year), whereas HS were assessed only once. We compared cognitive changes at 1year between three groups based on baseline FT4 levels: 1) lowest quartile (Q1, FT4<1.16ng/dL); 2) medium quartiles (Q2-Q3, FT4 1.16-1.54ng/dL); and 3) highest quartile (Q4, FT4>1.54ng/dL). No differences in TSH or FT4 levels were found between HS and FEP patients. All participants had FT4 levels within the normal range. HS outperformed FEP patients in all cognitive tasks. In relation to the relationship between FT4 levels and cognitive changes, a U-shaped pattern was observed: FEP patients from the middle quartiles (Q2-Q3) improved in attention/vigilance, whereas both extreme quartiles (Q1 and Q4) showed a worsening in this cognitive domain over time. Patients with lower FT4 (Q1) showed poorer baseline attention; therefore, lower baseline FT4 levels predicted a poorer prognosis in terms of attention performance. Our study suggests that baseline FT4 levels are associated with changes in attention and vigilance performance over one year in FEP patients.

Insecure maternal attachment is associated with depression in ADHD children.

The objective of this study was to analyze the possible association between maternal attachment style and comorbidity associated with childhood ADHD. We evaluated a total of 103 children with ADHD treated at a Child and Adolescent Mental Health Centre and their mothers. Comorbidity was evaluated using the MINI-KID interview. Maternal attachment was evaluated using the Adult Attachment Questionnaire. We considered child variables that could be associated with the clinical course of ADHD, such as symptom severity, age, gender, evolution time, academic level, and current pharmacological treatment; parental variables, such as the mother's psychiatric history, current psychopathology, marital status, academic level, income, and employment, were also considered. We found an association between maternal insecure attachment and comorbid depressive disorder in childhood ADHD. An insecure maternal attachment style must be considered in the assessment and treatment of childhood ADHD with comorbid depression.

Determinants of plasma homocyst(e)ine in patients with nephrotic syndrome.

Hyperhomocyst(e)inemia is an independent risk factor for atherothrombosis in several clinical settings in which renal function is impaired, but its prevalence in the nephrotic syndrome has not been investigated in detail, even though this syndrome provides an excellent model in which to study a possible link between albuminuria, proteinuria, and hyperhomocyst(e)inemia. We obtained plasma and urine from 27 patients with biopsy-confirmed membranous glomerulonephritis presenting nephrotic syndrome and 27 matched controls and determined the concentrations of homocyst(e)ine and proteins considered putative markers of glomerular and tubular function. Hyperhomocyst(e)inemia, defined as the mean +SD of the plasma homocyst(e)ine concentration of the controls [plasma homocyst(e)ine concentration >10.8 micromol/l] was present in 26% of the patients with nephrotic syndrome but in only 7.4% of the controls. Furthermore, the degree of hyperhomocyst(e)inemia was more severe in the nephrotic patients than in the controls. The existence of renal failure, tubular damage, and, interestingly, relatively well conserved glomerular function barrier were the main predictors of increased levels of plasma homocyst(e)ine. In conclusion, hyperhomocyst(e)inemia is a frequent cardiovascular risk factor present in patients with nephrotic syndrome and renal failure, but it is not directly associated with proteinuria.

Polymorphisms in human apolipoprotein(a) kringle IV-10 and coronary artery disease: relationship to allele size, plasma lipoprotein(a) concentration, and lysine binding site activity.

Elevated plasma levels of lipoprotein(a) [Lp(a)] represent a major independent risk factor for the development of atherosclerosis. The kringle IV type 10 of apolipoprotein(a) [apo(a)] is the primary lysine binding site (LBS) of Lp(a) and is associated with lesion formation in transgenic mice. The purpose of this study was to search for mutations in the apo(a) kringle IV type 10 which could alter the LBS activity of Lp(a) from patients with coronary artery disease. We found the DNA region of kringle IV type 10 of apo(a) to be mutable but relatively well preserved in the Spanish population. We identified a novel mutation which probably leads to a truncated form of apo(a) in a patient heterozygous for the mutation and with low lysine binding activity and low plasma Lp(a) concentration. Two other mutations have been previously identified in humans, the substitutions W81R and M75T. The W81R was not found in our sample, but the M75T mutation was present in 43% of patients with coronary artery disease and 23% of age-matched controls. The genotype TT conferred a significant risk for myocardial infarction (odds ratio 2.53). This association was not due to linkage disequilibrium with kringle IV repeats. The M75T polymorphism was not associated with the LBS function of apo(a), but it influenced plasma Lp(a) concentration.

Relación entre funcionamiento cognitivo y el perfil sintomático con la calidad de vida de pacientes con trastornos del espectro de la esquizofrenia / Relationship between cognitive performance and symptomatic profile in the quality of life of patients with schizophrenia spectrum disorders / Relação entre funcionamento cognitivo e o perfil sintomático com a qualidade de vida de pacientes com transtornos do espectro da esquizofrenia

Objetivo: evaluar la asociación de los síntomas psicopatológicos y el funcionamiento cognitivo con las medidas de calidad de vida subjetiva en pacientes con diagnósticos del espectro de la esquizofrenia. Metodología: se incluyeron 102 pacientes ambulatorios que cumplían criterios DSM-IV-TR para el diagnóstico de alguno de los trastornos del espectro de la esquizofrenia. Los datos se obtuvieron utilizando el Cuestionario Sevilla de Calidad de Vida, la Escala para el síndrome positivo y negativo de la esquizofrenia (PANSS), el Inventario de depresión de Beck y el Inventario de Ansiedad estado/rasgo. Resultados: el análisis de regresión múltiple mostró que los aspectos favorables de la calidad de vida están afectados por la desorganización cognitiva, los síntomas positivos, depresivos y ansiosos. Por otra parte, la presencia de síntomas de carácter emocional está fuertemente asociada a los aspectos desfavorables, lo que hace pensar que esta dimensión sintomática deteriora la percepción subjetiva de bienestar de los pacientes con trastornos del espectro de la esquizofrenia. Conclusiones: los síntomas psicopatológicos y la función cognitiva afectan la calidad de vida subjetiva en pacientes con esquizofrenia. Si el objetivo con el tratamiento es lograr que mejore la calidad de vida percibida, las estrategias deben considerar la búsqueda de la mejoría de los síntomas de carácter emocional, como la depresión, la ansiedad y el malestar emocional.

Objective: To evaluate the association of psychopathological symptoms and cognitive functioning with the measures of subjective quality of life of a group of patients diagnosed with the schizophrenia spectrum. Methodology: The study included 102 outpatients who met the DSM-IV-TR criteria for the diagnosis of schizophrenia spectrum disorders. The data were obtained by means of the Seville Questionnaire of Quality of Life (CSCV), the scale for the positive and negative schizophrenia syndrome (PANSS), the Beck Depression Inventory (BDI) as well as the state-trait Anxiety Inventory (STAI). Results: The multiple regression analysis showed, on one hand, that favorable aspects of quality of life are affected by cognitive disorganization, positive, depressive and anxiety symptoms. On the other hand, the presence of emotional symptoms is strongly associated with unfavorable aspects, which suggests that this symptomatic dimension impairs the subjective perception of well-being of patients with schizophrenia spectrum disorders. Conclusions: Psychopathological symptoms and cognitive function affect the subjective quality of life in patients with schizophrenia. If the aim of the treatment is to improve the perceived quality of life, the strategies should consider seeking the improvement symptoms of an emotional nature, such as depression / anxiety and emotional distress.

Maternal psychiatric history is associated with the symptom severity of ADHD in offspring.

Controversy exists about the role of parent psychopathology in persistence and severity of attention deficit hyperactivity disorder (ADHD) symptoms in their children. Here we aimed to analyse the potential association between the severity of ADHD symptoms in children and the presence of psychiatric and ADHD symptoms in their biological parents. Seventy-three triads of children and their parents who were in active treatment for their diagnosed ADHD were evaluated in our Child and Adolescent Mental Health Centers. The mental health of the parents was also assessed. The general psychopathology of the parents was evaluated using the Symptom Checklist-90-R (SCL-90-R), and symptoms of hyperactivity were examined using the Adult ADHD Self-Report Scale (ASRS v.1.1). The severity of symptoms in children was assessed using the ADHD Rating Scale-IV (ADHD-RS-IV). Variables that could have affected the clinical development of ADHD such as sex, evolution time, age, academic level and the presence of comorbidities were controlled. The severity of the symptoms in children with ADHD was significantly related to the psychiatric history of their mother, the younger age of the child and the presence of a comorbid conduct disorder in the child. We discussed the importance of screening for parental psychopathology in clinical practice.
